Tags

I am the Install manager at Fire & Ice, since 2022. I have spent 28 years in this business and have experienced nearly every aspect of HVAC from Industrial, commercial, and residential buildings. From design, install, service, or sales, if it moves air, I've worked on it.

About This Article

An in-depth air conditioner installation procedure guide. Learn how installation procedures dramatically impact the lifespan and effectiveness of your air conditioner.

I'm non going to lie, the installation process for a new air conditioner is complicated. When customers inquire me what's involved in the process, they're often shocked to learn how much goes into it.

The more than worrying fact is that at that place are many HVAC companies and air conditioner installers who don't know all the steps that should be function of a practiced installation. It's easy to cut corners and then that an A/C system runs "adept plenty." Merely "skilful plenty" frequently ways losing thousands of dollars in energy costs over the life of your organisation, and decreased comfort for y'all and your family unit. This is unacceptable.

Do you desire a sleek, efficient car powering your air conditioning, or a comfort-robbing trashcan outside your domicile? I'm guessing you lot'd prefer the former. Well, you're in luck.

In this article, we are going to cover the unabridged air conditioner installation process in detail, from start to end! If you lot're committed to getting the most from your air workout system, read on. Past the end, yous'll have the peace of heed that comes with understanding each step. It will also allow you to choice a company whose installation procedure is upwardly to snuff.

Importantly, this is not a DIY guide. Air-conditioning installation should always exist handled by a licensed professional. Once yous read each step involved, it should be easy to meet why.

Planning the Replacement or New Installation of Your Primal Air Conditioner

The earth has inverse then much in just the past few years. So imagine how much has inverse in 10 years. Or twenty. Or 30.

Most existing air conditioners that are replaced today are between the ages of 8 to 30 years former.

Mod air conditioners are twenty-50% larger in elevation, length, and width. This allows for a larger coil which, in turn, makes the air conditioner more than efficient. Considering of the larger size of modern air conditioners, the electric current location of your existing air conditioner may not adapt the new one. Sometimes the air conditioner must be relocated, particularly if there are state or manufacturer regulations on space clearances surrounding your unit of measurement. Others require that unit to be within a certain distance to the utility meter. In some cases, this creates additional costs.

This is the first consideration for a homeowner, considering information technology may require moving equipment or modifying your home'south ductwork.

So what'south the adept news? Modern air conditioners are significantly quieter and more efficient than their predecessors, so your costs are oft offset by these benefits.

Collecting A/C Information During the Dwelling house Gauge

During your initial in-home visit, the estimator has the responsibility of reviewing the existing air-conditioning system. Of import information needs to be nerveless so they can provide you lot an accurate proposal. This information is then passed to the installation team.

Depending on the chore, specialized equipment may exist needed, which the installation team can bring with them because of this step.

Having the proper information before the day of installation increases the chances of the job being completed successfully and promptly.

The Arrival of the Install Team, Review, and Safety

Earlier your installation squad arrives, you should receive a call or text letting yous know they're on their way.

Many good HVAC Companies will besides send pictures accompanied by bios of the installation squad that will be working at your home ahead of time. This is an additional safety and comfort gene before a stranger enters your habitation.

In one case they make it, the pb installer will share and review the job information with you lot. This is frequently included in a bundle that includes details of the job. This parcel contains the equipment information, accessories to exist installed, and any special instructions given by you to the estimator earlier the sale.

Information technology'due south of import to allow a few moments for this review. This will prevent costly and aggravating mistakes from happening during the installation. Communication is a key component to a successful installation.

While you are reviewing the job details with the lead installer, the other fellow member(s) on the team volition use this time to start laying downwardly floor protection and getting tools and equipment in place. They will besides start a prophylactic procedure that includes turning off electrical circuits and gas supply to the existing HVAC equipment.

Removing Your Existing Fundamental Air Conditioner

Your existing air conditioner contains a refrigerant that needs to be removed earlier a new one tin exist installed. Co-ordinate to the EPA standards, it is unlawful to openly vent this refrigerant into the atmosphere.

A device known as a recovery motorcar must exist used forth with a recovery tank to safely and legally remove the refrigerant in the existing primal air conditioner system. This is the just process that allows for the safe removal and proper handling of the refrigerant.

Any individual handling whatever refrigerant or equipment containing refrigerant must have an individual EPA certification. An EPA certification only certifies the name listed on the certification. Therefore, each member of the installation squad, service team, or anyone who might handle refrigerant or equipment containing refrigerant are required by law to have their ain individual EPA certification.

In one case the refrigerant is recovered properly, electrical wiring is disconnected from the existing air conditioner. Near the air conditioner is a disconnect box, which is a safety device in case of emergencies. Information technology tin can close down your A/C unit of measurement.

From the disconnect box, a "whip" (flexible electric conduit) carries the power to the air conditioner. Adept HVAC companies supercede the disconnect and the whip when replacing an air conditioner, to ensure organisation condom.

In cases where an one-time system lacks a disconnect box, a new i is required by condom codes to be installed with the new air conditioner. There are specific installation guidelines for sizing and wiring the disconnect properly.

The circuit breaker should exist turned off in the electrical panel before whatever piece of work is to exist done inside the service disconnect. In one case all the existing connections are safely removed, the existing air conditioner is prepare to exist removed.

Preparing the Area for the New Central Air Conditioner

In most cases, the existing location of the air conditioner will require some prep piece of work before the new air conditioner can be set in place. This prep piece of work includes replacing the pad that the new air conditioner will attack.

New air conditioners are larger and taller than their predecessors. There are besides times when the footing has sunk. Before the new pad tin can be ready, the basis must exist leveled. Good HVAC companies utilise a gravel base of operations to level out or build up the area where the new air conditioner volition be placed.

Some people think it is better to have a concrete pad poured for the new air conditioner to assail. A concrete pad is non necessary and can crack and shift drastically. When this happens, information technology is very difficult to repair or remedy. Instead, a composite pad is recommended. The composite pad is purposely designed to be outside and last the lifetime of the new air conditioner. Additionally, it's often meliorate equipped than physical to absorb vibrations from the machine, which can reduce noise and shaking.

One time the new air conditioner is installed, it cannot be moved or lifted safely without harm in nearly cases. Many internal elements are rigid and pressurized. Moving it after it is connected could permanently impairment the system. A composite pad can avoid impairment to the air conditioner if it needs to be leveled in the future.

Removing the Existing Indoor Evaporator Curlicue

The indoor evaporator curl is the other half of your ac system that sits to a higher place the furnace, though in some cases it will sit below the furnace. This is what the other end of the refrigerant lines are connected to.

The indoor evaporator roll has two variations. Ane is cased and the other is uncased. In either application, the canvass metal plenum must exist disconnected earlier the new coil can exist installed. This process tin be complicated when access to the coil is restricted.

The almost common restrictions are rooms congenital around the organization such equally closets or finished basements. This prevents access to all sides of the coil or plenum. An additional charge may be added to the toll of the job based on difficulty. Considering most indoor coils are more than efficient, they are taller. Additional prep piece of work to the supply plenum may be required before the new curl tin can be installed.

Removing the Existing Copper Refrigerant Lines (Line Gear up)

Next, the existing refrigerant line set tin be removed. This is a set of 2 copper lines through which the refrigerant travels from the outdoor condenser, then back into the indoor evaporator coil.

The refrigerant line prepare is usually strapped to the bottom of the floor joists. These straps are removed, and the line set is taken down. It's recommended that the line set be replaced in every example that it is exposed and accessible.

Refrigerant travels through the lines forth with oil. In older air conditioning systems, the oil in the existing line set is unlike from the oil plant in the new air conditioner. These oils cannot be mixed without damaging the new air conditioning system.

Sometimes the line ready is concealed by a ceiling or in a wall, or it is buried underground or in concrete. Sometimes providing access is not an option or possible. In these cases, you have the option of finding a new location to run a new line set or reusing the existing line set up remains. If the existing line set must be reused, it must exist flushed and cleaned properly, then pressure level tested. It is never recommended to keep an existing line set if information technology tin can be replaced.

Installation of the New Indoor Evaporator Roll

In that location are two options when installing a new evaporator coil for whatever new air conditioner system: cased and uncased. The preferred choice is a cased roll, because information technology comes in an insulated cabinet with removable panels on the front that allow access to the coil inside.

The cased ringlet is also designed to sit on pinnacle of the furnace without any modifications, which makes repairs and modifications easy. In virtually cases, it volition exist painted to match the color of the furnace. The biggest benefit of using a cased whorl is that it comes pre-cased by the manufacturer. This makes failure from an improper installation highly unlikely, regardless of the skill level of the installer.

When using a cased coil, it is already "installed" past the manufacturer and only needs to exist placed on the top of the furnace. The final step at that betoken is to connect and seal it to the existing sheet metal plenum.

An uncased coil is the coil without an insulated cabinet. They accept more installation requirements and longer training fourth dimension. They are available in the same variations every bit the cased ringlet.

Uncased coils are typically more than hard to install. However, an uncased coil will provide the same comfort and exist just as efficient equally a cased coil when installed properly.

Before the coil tin be built into the existing canvass metal supply plenum, there is specific preparation required. These requirements are specified by the manufacturer. Failure to follow the installation manual's guidelines may result in damage to the furnace equally well as the coil.

The drain pan on the coil is plastic, so runway need to be fabricated by the installer to make sure the coil is sitting the proper distance above the furnace estrus exchanger. This keeps the drain pan from melting. If the drain pan melts into the furnace, it could permanently impairment the furnace or cause a fire.

Once the rails are built and installed, the coil can be installed into the supply plenum. If the plenum is larger than the roll, a sail metal pan must be built with an opening provided below the coil. This opening needs to mirror the bottom opening of the curlicue for proper airflow from the furnace going through the coil.

If the opening is non large plenty, or too much air goes around the roll instead of through it, the coil will freeze into a block of ice. This can damage the ringlet and crusade a refrigerant leak by great the tubing carrying the refrigerant.

Once those are installed, the final step is edifice the front end of the plenum. It is possible to build an access panel door into the plenum to comprehend the curl. This is not required by any lawmaking or industry specification, so it would be up to the installer. In all scenarios, the encompass must accept holes provided for the refrigerant lines, and so likewise for the condensation lines to exist connected.

The type of coil chosen is mostly based on the details of the installation. Some won't allow for a cased coil due to sizing restrictions, for example. Regardless, if the coil is installed per code and manufacture specifications to the existing duct system, can bleed properly, and is sealed from air leaks, you will savour the same level of comfort. At that place is no difference in warranty or life expectancy between either blazon of ringlet.

Installation of the New Copper Refrigerant Lines (Line Gear up)

The new refrigerant line set is a combination of two individual copper lines. One line is always bigger than the other and is insulated. The bigger line is called the suction line, and the little one is called the liquid line. They come packaged together, rolled in a curl. Information technology is bachelor in multiple selections of lengths, from fifteen-50 feet. You will rarely need more than fifty feet in a residential home.

The primal is installing the line with as few bends and turns as possible. When these bends are necessary, the soft copper can be bent past manus or a tubing bough.

It'southward common to install the line gear up every bit close to your dwelling house's beams and ductwork equally possible. It'due south also recommended that you secure the line every 4-6 feet. Plastic or copper strapping is common. Metal straps or clamps can be used, but it's important to protect the copper wiring if the clamps bear on them.

If you don't properly protect the line, it can corrode. Galvanic corrosion (also called bimetallic corrosion) is the breakup of metal when 2 dissimilar metals come into contact. This does have some fourth dimension to occur. Nevertheless, if allowed to occur, information technology could eventually reduce the integrity of the copper refrigerant line over time until it causes a leak.

After the hangers are installed, the line prepare tin can at present be put in place. Typically, an installer will start with the suction line and curlicue out ane finish a few feet, leaving the rest of the curlicue in a coil. They then push the unrolled section through a pigsty drilled through the ring board of the house to the outside, near the air conditioner. Enough of the line is pushed out to achieve the service valve of the air conditioner.

Eventually, the installer will connect this line to the air conditioner itself. The hole size will exist between two-2.5" in bore, depending on the type of line ready being used.

After the line is exterior past the air conditioner, the line is secured by hangers nearly the hole and so another hanger back a couple of anxiety. The line is then advisedly uncoiled and formed along the floor joists up confronting the torso line ductwork or a beam, equally direct equally possible until long radius turns or bends are needed. Along the way, it gets put into the hangers that have been installed previously, securing it in place.

The line set will run from the air conditioner exterior to the new indoor evaporator ringlet on top of the furnace. After the suction line has been installed and secured, the smaller, liquid line is run along the suction line, secured in the aforementioned hangers.

A line set should be new, installed every bit 1 piece, free from any sharp bends or kinks, and secured with an appropriate hanging system.

In that location will also be a modest, low-voltage control wire that runs from the furnace along the line set to the air conditioner outside. The small existing wire coming from the thermostat to the furnace sends a low voltage signal to the air conditioner to turn on and off when a call for cooling is needed or has been satisfied.

Setting the New Air Conditioner Condenser

And so far, nosotros've set the pad, leveled it, and our refrigeration lines and electrical disconnect are set to exist wired into the new air conditioner condenser.

Removing the new air conditioner and setting it on the pad is step one. After uncrating the unit, a practiced installer volition inspect for any damage. Sometimes panels or coils will go damaged in transit. Any damage should exist reported to yous immediately.

Burn & Ice Heating and Ac runs multiple inspections on equipment, both when it arrives and when information technology's installed, to ensure it is in working order.

If there is a dent, that doesn't necessarily mean there is any damage that will bear on performance. However, y'all always accept the right as a client to not accept the damaged unit of measurement and ask for another i.

The line set that was installed in the previous step is then formed and fitted to the appropriate service valve on the new air conditioner. The service valve is a connection betoken for the line set, and besides isolates the refrigerant contained inside the unit. Service valves also allow for the outdoor condenser portion of the air conditioner to be isolated from the indoor coil and line prepare for future service or repair needs when needed.

Isolating the refrigerant keeps you from having to replace it with all new refrigerant in instance of a repair in the future.

After the line gear up is fitted to the service valves, they must be brazed in. Brazing, a form of welding, is a process using two gases (oxygen and acetylene) and a filler rod made of an alloy metallic and silver to join the copper line set and service valves. The valves are heated to a minimum of 1200 degrees Fahrenheit or until the filler rod volition menstruation to weld the connectedness.

If this process is completed properly, the copper line prepare, the filler rod, and the service valve are all melted together for a tight, leak-free connection.

Filter Dryer Installation

Filter driers are a key component in the refrigerant organization. They serve ii main functions. The about important part of a filter drier is to blot moisture. The 2nd is to provide physical filtration.

When installing a new air conditioner condenser, you must ever install a liquid line filter drier into the refrigeration system. Most new air conditioner condensers come with a liquid line filter drier for you to install.

Manufacturers recommend the filter drier exist installed close to the expansion valve (TXV) at the indoor scroll, as often as possible. This keeps the TXV protected and keeps the filter drier from beingness exposed to weather where it could rust.

There is besides an arrow for catamenia direction. This pointer must always be in the direction that is going into the indoor coil.

Any contaminants in the refrigeration system are harmful. H2o or wet is the worst.

Moisture enters the system in different ways. If a organisation is non evacuated properly, moisture will be in it. Wet can as well come from leaks or motor windings. The water tin can cause corrosion and create failure in metallic parts.

Water or moisture can too react with the oil in the refrigerant organisation. This is chosen hydrolysis, which forms acids in the system. Acids, moisture, or any other contamination in the lines will be extremely dangerous to the integrity of your new air conditioning system.

All expert HVAC companies have strict processes in identify for their install teams to prevent failure as much as possible. Whatever time a refrigerant line is open to the atmosphere, it is vital to install a new filter drier. This is true of installations as well as service repairs.

This brazing process is the same for connection to the indoor evaporator curl. This, once again, involves open flames and should only be performed by a trained professional.

The gases used in the process are explosive. There is an open up flame outside and inside the home. It can be dangerous to the installer, the homeowner, and the home, causing permanent harm without proper training. Following manufacturer and safety guidelines is key.

Preparing the line fix for refrigerant in this mode is the most important pace in ensuring the safety and efficiency of your air conditioner.

Sadly, this process is unknown or not followed to almost install teams. Not all companies are equal in training or processes, and many contractors lack the proper equipment. A adept HVAC visitor will accept all the tools and processes needed to install the air conditioner professionally and thoroughly.

Subsequently the line set is fitted properly into the service valves and indoor coil, rut protection needs to be applied. Heat protection can be a heat-absorbing paste, wet towels, or rags. Anything that would go along the heat spreading into either of the coils is acceptable. The service valves on the outdoor condenser contain condom O-rings that will cook if they aren't protected. If the valves are overheated and the O-rings are damaged, the refrigerant will leak past the valve into the line set up, losing the manufacturing plant charge.

From the manufactory, the air conditioner condenser is prepared, cleaned, and the refrigerant is added. If the refrigerant is exposed before the process is completed, it becomes contaminated, forth with the condenser roll. If this footstep is performed improperly, all the refrigerant would need to be recovered and the condenser coil would need cleaned and prepared again before any refrigerant could exist added.

About indoor coils have a metering device called an expansion valve that volition be damaged if not protected from the rut during brazing. If these get as well hot, or any contaminants are introduced, the expansion valve will be compromised and fail to operate.

In one case the heat protection is completed, a tank containing a gas called dry nitrogen is hooked up to a regulator and possibly a manifold approximate set up. This allows the nitrogen to be purged while brazing. The nitrogen protects the inside of the copper tubing from oxidizing during brazing. The damage will not always be present immediately.

The HVAC manufacture requires brazing with nitrogen every time to prevent this impairment.

Brazing with nitrogen, when done properly, will give the system maximum opportunity for operation, reliability, and dependability. Afterwards the system is brazed in both the indoor and the outdoor components, information technology must be checked for leaks using the aforementioned dry nitrogen, upward to a specific corporeality of pressure. Using the dry nitrogen to pressure test the system achieves three things:

1. Information technology'southward a preliminary leak test.
2. The dry nitrogen volition pick upwardly moisture.
3. Information technology volition also purge some contaminants out of the system upon its release.

Information technology is very important to verify with the installation transmission provided by the manufacturer what they recommend for pressure. Most systems are designed for 150 PSI when testing.

If there is likewise much pressure level added, issues can occur. If the pressure level is likewise high for the O-ring seal, for instance, the nitrogen will drain into the refrigerant, contaminating information technology.

In this scenario, all the refrigerant contained in the condenser from the factory will be compromised and volition have to be recovered, so the coil cleaned and prepped for more refrigerant.

If the preliminary leak test with nitrogen holds for a minimum of x minutes, and so it'southward time to move on to the adjacent crucial step: vacuuming the organization.

Typically a system is vacuumed to a minimum of 500 microns. The manufacturer'due south recommended vacuum is found in the installation transmission. Refrigeration systems are designed to operate with just oil and refrigerant flowing through them.

Our atmosphere is made up of oxygen, nitrogen, and moisture. These are enemies to the system's performance and may enter the system during installation or servicing. Removal of these, along with air or other non-condensable products, is required. This is achieved through the vacuum process when installing the air conditioner. The vacuum process can take no less than xxx minutes and upwards to an hour or more than depending on the size of equipment coils and length of line fix.

Failure to provide a dry out, moisture-free temper before introducing the refrigerant into the rest of the system volition in all cases promote an inconsistent operation, and eventually permanent failure of the system.

To achieve a successful vacuum on an air conditioning system there are several key tools and equipment that must exist used:

1. A reliable vacuum pump
2. A micron gauge
3. Manifold and hoses
4. Vacuum rated core removal tool

The vacuum must achieve 500 microns or less in the system and agree the vacuum for this to be successful. This is too the second and terminal leak exam. If a system does not concord a vacuum, then there is a leak somewhere.

One time a proper vacuum is accomplished and has proven to hold, the system is ready to have refrigerant introduced to it. Refrigerant is the but product that tin "break" the vacuum. If hoses are asunder from the system before the refrigerant has been released into the system, the atmosphere will suspension the vacuum. If this happens, the vacuum process must be redone before refrigerant can be introduced.

With the hoses still connected to the service valves of the air conditioner, the refrigerant is released into the organisation, breaking the vacuum past opening the suction-side service valve offset followed by the liquid side 2nd.

Installation of the New High- and Low-Voltage Wiring

For the ac system to operate, the high- and low-voltage wiring must be reconnected. Using the existing power supply from the electric console inside the home, the installer will mount a new service disconnect box. The disconnect is mounted securely to the side of the house using appropriate fasteners, based on the type of surface information technology is being mounted to.

There are two main types of disconnect boxes. One is fused and the other is non-fused. They are both appropriate to employ outdoors. A fused disconnect allows the proper overcurrent protection required by the manufacturer. This type is most common and required when the main circuit from the panel exceeds the maximum required overcurrent protection. It also allows for additional safety to the air conditioner condenser.

A non-fused disconnect may exist used only in cases where the breaker matches identically to the articles listed maximum overcurrent protection. There is a minimum and a maximum required overcurrent protection. You must be within these guidelines. The system will not laissez passer the code requirements if they are not.

For instance, if yous have an existing xl-amp circuit that supplies the disconnect, but the listed overcurrent protection is merely 30 amps, you must use the fused disconnect and install 30-amp fuses with it to properly protect the air conditioning condenser. If the amperage from the billow matches the maximum or the minimum overcurrent protection, a non-fused disconnect is acceptable.

The service disconnect has specific locations for the high voltage circuit from the panel to be continued and specific locations for the power to get to the air conditioner itself through the electrical whip. They are identified as "Line" (wiring from the electrical panel) and "Load" (the whip that takes power to the air conditioner). This allows the pull inside the service disconnect to break or disconnect the power supply to the air conditioner without having to close the breaker off from the main console.

Because the air conditioner is outside, it would be cumbersome to run in and out of the house to plough the power on or off in case of emergency or servicing. The service disconnect is required by state and local code requirements.

There are also requirements for placement of the air-conditioning condenser. Information technology boils down to making sure there is proper accessibility. All the electrical connections should be fabricated according to the NEC (National Electrical Lawmaking). The low-voltage control wire is connected directly into the air conditioning condenser at the proper locations according to the air conditioning condenser installation instructions.

This is the "signal" from the control board in the furnace sent through the wire to the air conditioner when the thermostat calls for cooling. The depression-voltage control wire is what allows the air conditioner to bicycle according to the parameters prepare regarding temperature and humidity within the home. The low voltage wiring is connected to the command lath inside the furnace on designated terminals.

Installation of the Condensate Drain Line

The moisture removed from the home during the cooling process travels down a plastic PVC pipe. It must be connected to the main side of the evaporator coil. The evaporator coil has a main and a secondary drain location. The primary condensate drain line will travel from the indoor evaporator roll to an appropriate floor drain or condensation pump.

A condensation pump is used where a proper flooring drain does non exist in the home. In that location are also other reasons where a condensate pump is required or is beneficial to install. The important thing to call up if a condensate pump is used is that it must be serviced a minimum of twice a year to maintain proper performance.

Whatever condensate tubing or piping should be secured and glued with the proper cement. A trap and an overflow prophylactic switch must as well be installed in the condensate system. This is to protect the equipment and the surface area from flooding due to a restriction. The prophylactic overflow switch is continued to the secondary port on the indoor evaporator curlicue and wired into the furnace control to shut downwardly the system when it is tripped.

Startup Commissioning Process

The startup and commissioning (testing) process is done afterward the system is completely installed and set to operate. The system is turned on and must run for fifteen-20 minutes. This will let the refrigerant to menses through the organisation and get-go the ac process.

Upon initial startup of the new air conditioning system, the house should be very warm or have a "load" with a warm plenty temperature within the dwelling to allow for the minimum potential to charge the organization accurately. A temperature above 75 degrees Fahrenheit is recommended in most cases. This allows the components in the air conditioning organization to be in full performance to allow maximum cooling potential during charging.

Sometimes running the furnace to heat the house is a mutual practise to provide the necessary load on the home. Afterward 15-20 minutes of operation, the system tin at present be commissioned.

A adept installer will check the thermostat functioning, organisation sequence of functioning, and multiple other areas. While the organisation is operating, the post-obit data is important to collect to ensure proper operation within manufacturers' specifications:

1. Suction and liquid line pressure
2. Suction and liquid line temperature
3. Superheat
4. Subcooling
5. Outdoor ambient dry out bulb temperature
6. Indoor ambient dry bulb temperature
7. Indoor wet bulb temperature
8. Return air temperature
9. Supply air temperature
10. Static pressure from return side, supply-side, and total static readings
11. Temperature drop calculated
12. Loftier voltage current reading
13. Amperage on the blower motor, outdoor fan motor, and compressor
14. Low voltage current reading
15. Line ready length
16. Amount of refrigerant, if whatsoever, added to the system
17. Distance above or below the outdoor unit is in relation to the indoor coil
18. Blower speed tap/CFM recorded

This is the basic list of the proper data that should be known and recorded. This is the only way to know for sure how the system is operating and if it is within manufacturing specifications. If any of these exercise not fall within manufacturer specifications, your arrangement may non be warrantied by the manufacturer.

Commissioning is of import for several reasons. For you, the peace of mind that yous are receiving a properly set up and adapted system for maximum comfort, efficiency, and dependability. Information technology besides ensures the manufacturer's warranty volition exist in full result. The benefit to the company installing the system is that it gives a baseline of operational operation in case any issues arise later.

It also gives the installing team confidence that before they go out, your system is in perfect operation. It is very common for systems to be installed and started upward without much consideration for proper commissioning.

Unfortunately, many companies turn it on and walk away the moment cold air is coming through the vents.

Proper commissioning is a specific process that requires training and special equipment to perform the process correctly. Information technology besides requires additional time and labor on a chore site. Commissioning is the only way to know for sure exactly how well your system is operating.

Why would a company skip this step, then? In a word: cost. Skipping this process costs a company less, which in plough might lower your initial investment slightly. This is a long-term gamble, though, with your money, your safety, and your comfort.

A proficient HVAC contractor will take trained installation teams that volition properly committee your air conditioner before they exit the job.

Clean up and Closing Process

The cleanup process is comparatively simple. All material and old equipment should exist loaded up and taken away from the home. The floor protection should be rolled upwardly concluding, keeping all debris from the installation inside the drop cloth and out of your home.

All areas should be swept and free of whatever materials or debris. You should await to see the expanse in the aforementioned condition in which it was found.

A walkthrough of what was done during the installation should be completed with yous. Going over safety, maintenance, warranty, and all special instructions are expected.

As a final mechanical footstep, a locking cap should exist placed on the outdoor portion of the unit. This cap can simply exist unlocked with the correct key. This is to preclude tampering with your equipment, and also to prevent theft of the refrigerant. This cap is ofttimes a specific color, which will let a technician know which type of refrigerant your system uses.

A visual inspection of the piece of work completed should as well be offered. Finally, a review of the commissioning and thermostat functioning. Afterward the final walkthrough, final signatures and payments are nerveless.

Installation Completed Professionally

The job is now complete!

The procedure may seem long and complicated, but in the hands of a skilled installation team, the unabridged process should exist second nature.

Don't cut corners with installation. Your money and condolement are at risk if whatever of these steps are skipped. Knowing the total procedure will let you to concur companies answerable when you decide to invest in a new air workout system. The result will be a comfortable, efficient, long-lasting product.
