How To Install Air Conditioner Cover
Air Conditioning Organisation Installation Process From Start to Finish
I am the Install managing director at Fire & Ice, since 2022. I have spent 28 years in this business and have experienced near 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.
An in-depth air conditioner installation process guide. Learn how installation procedures dramatically affect the lifespan and effectiveness of your air conditioner.
I'm not going to prevarication, the installation process for a new air conditioner is complicated. When customers ask me what's involved in the process, they're often shocked to learn how much goes into information technology.
The more 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 part of a good installation. Information technology's easy to cutting corners and so that an A/C arrangement runs "skilful enough." Only "good enough" often ways losing thousands of dollars in energy costs over the life of your organisation, and decreased condolement for y'all and your family unit. This is unacceptable.
Do you want a sleek, efficient machine powering your air conditioning, or a comfort-robbing trashcan outside your home? I'm guessing you'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 finish! If you're committed to getting the about from your air conditioning organization, read on. Past the terminate, you'll have the peace of mind that comes with understanding each step. It volition also allow y'all to option a visitor whose installation procedure is up to snuff.
Importantly, this is non a DIY guide. Ac installation should always be handled by a licensed professional. One time yous read each step involved, it should be easy to see why.
Planning the Replacement or New Installation of Your Central Air Conditioner
The globe has changed and so much in just the past few years. So imagine how much has changed in ten years. Or 20. Or 30.
Almost existing air conditioners that are replaced today are between the ages of viii to 30 years old.
Mod air conditioners are twenty-l% larger in height, length, and width. This allows for a larger coil which, in plow, makes the air conditioner more efficient. Because of the larger size of modern air conditioners, the current location of your existing air conditioner may non suit the new one. Sometimes the air conditioner must exist relocated, especially if there are state or manufacturer regulations on infinite clearances surrounding your unit. Others require that unit of measurement to be within a sure distance to the utility meter. In some cases, this creates additional costs.
This is the first consideration for a homeowner, because information technology may require moving equipment or modifying your abode'due south ductwork.
So what's the good news? Modern air conditioners are significantly quieter and more efficient than their predecessors, so your costs are often offset by these benefits.
Collecting A/C Data During the Dwelling house Estimate
During your initial in-dwelling visit, the calculator has the responsibility of reviewing the existing air conditioning system. Important information needs to be collected so they tin can provide yous an accurate proposal. This information is and so passed to the installation team.
Depending on the job, specialized equipment may be needed, which the installation team tin can bring with them because of this footstep.
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 Prophylactic
Before your installation team arrives, you should receive a call or text letting you know they're on their way.
Many good HVAC Companies volition as well send pictures accompanied by bios of the installation team that will be working at your habitation ahead of time. This is an additional rubber and comfort factor before a stranger enters your home.
In one case they arrive, the lead installer will share and review the job information with you. This is oftentimes included in a packet that includes details of the job. This bundle contains the equipment information, accessories to exist installed, and whatsoever special instructions given by you to the estimator earlier the sale.
It's important 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 atomic number 82 installer, the other member(s) on the squad volition utilise this fourth dimension to outset laying downwardly floor protection and getting tools and equipment in place. They will too get-go a safety process that includes turning off electrical circuits and gas supply to the existing HVAC equipment.
Removing Your Existing Primal Air Conditioner
Your existing air conditioner contains a refrigerant that needs to exist removed before a new one can be installed. According to the EPA standards, it is unlawful to openly vent this refrigerant into the atmosphere.
A device known as a recovery automobile must exist used forth with a recovery tank to safely and legally remove the refrigerant in the existing central air conditioner system. This is the just process that allows for the safe removal and proper handling of the refrigerant.
Any individual handling any refrigerant or equipment containing refrigerant must have an individual EPA certification. An EPA certification only certifies the name listed on the certification. Therefore, each fellow member of the installation squad, service team, or anyone who might handle refrigerant or equipment containing refrigerant are required by law to accept their own individual EPA certification.
In one case the refrigerant is recovered properly, electric wiring is disconnected from the existing air conditioner. Most the air conditioner is a disconnect box, which is a prophylactic device in case of emergencies. It can close downwards your A/C unit.
From the disconnect box, a "whip" (flexible electrical conduit) carries the power to the air conditioner. Skilful HVAC companies replace the disconnect and the whip when replacing an air conditioner, to ensure system condom.
In cases where an old system lacks a disconnect box, a new i is required past safety codes to exist installed with the new air conditioner. There are specific installation guidelines for sizing and wiring the disconnect properly.
The circuit breaker should be turned off in the electrical panel before any work is to be done inside the service disconnect. Once all the existing connections are safely removed, the existing air conditioner is ready to exist removed.
Preparing the Area for the New Fundamental Air Conditioner
In most cases, the existing location of the air conditioner will require some prep piece of work earlier the new air conditioner can exist set in place. This prep work includes replacing the pad that the new air conditioner will set up on.
New air conditioners are larger and taller than their predecessors. There are besides times when the ground has sunk. Before the new pad can be set, the basis must be leveled. Practiced HVAC companies use a gravel base to level out or build upward the area where the new air conditioner will be placed.
Some people think information technology is better to have a physical pad poured for the new air conditioner to set on. A concrete pad is not necessary and tin cleft and shift drastically. When this happens, it is very difficult to repair or remedy. Instead, a blended pad is recommended. The composite pad is purposely designed to be outside and terminal the lifetime of the new air conditioner. Additionally, it's often ameliorate equipped than concrete to blot vibrations from the car, which can reduce noise and shaking.
Once the new air conditioner is installed, it cannot be moved or lifted safely without damage in most cases. Many internal elements are rigid and pressurized. Moving information technology after it is connected could permanently impairment the arrangement. A blended 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 whorl is the other half of your air-conditioning system that sits above 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 ringlet has two variations. One is cased and the other is uncased. In either application, the canvas metal plenum must be disconnected before the new curl tin can be installed. This procedure can be complicated when access to the coil is restricted.
The most common restrictions are rooms congenital around the organization such as closets or finished basements. This prevents access to all sides of the curlicue or plenum. An additional accuse may be added to the cost of the job based on difficulty. Considering virtually indoor coils are more efficient, they are taller. Additional prep work to the supply plenum may exist required before the new coil can be installed.
Removing the Existing Copper Refrigerant Lines (Line Set)
Next, the existing refrigerant line gear up can be removed. This is a ready of two copper lines through which the refrigerant travels from the outdoor condenser, then back into the indoor evaporator scroll.
The refrigerant line set 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 gear up be replaced in every case that information technology is exposed and attainable.
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 constitute in the new air conditioner. These oils cannot exist mixed without damaging the new ac system.
Sometimes the line set up is concealed past a ceiling or in a wall, or it is buried underground or in physical. Sometimes providing access is not an selection or possible. In these cases, you lot have the option of finding a new location to run a new line set or reusing the existing line set remains. If the existing line set must be reused, it must be flushed and cleaned properly, then pressure tested. It is never recommended to continue an existing line set if it can be replaced.
Installation of the New Indoor Evaporator Gyre
There are 2 options when installing a new evaporator curlicue for whatsoever new air conditioner system: cased and uncased. The preferred option is a cased coil, because it 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 top of the furnace without whatever modifications, which makes repairs and modifications easy. In well-nigh cases, it will be painted to match the color of the furnace. The biggest benefit of using a cased roll 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 gyre, it is already "installed" by the manufacturer and merely needs to exist placed on the pinnacle of the furnace. The terminal step at that point is to connect and seal information technology to the existing sheet metal plenum.
An uncased scroll is the gyre without an insulated cabinet. They accept more than installation requirements and longer grooming fourth dimension. They are available in the aforementioned variations equally the cased coil.
Uncased coils are typically more than difficult to install. Withal, an uncased scroll will provide the same comfort and be merely as efficient every bit a cased whorl when installed properly.
Earlier the coil can be built into the existing sheet metal supply plenum, there is specific grooming required. These requirements are specified by the manufacturer. Failure to follow the installation transmission'southward guidelines may consequence in harm to the furnace as well as the roll.
The bleed pan on the coil is plastic, and so rails need to exist fabricated by the installer to brand sure the coil is sitting the proper distance above the furnace heat exchanger. This keeps the bleed pan from melting. If the bleed pan melts into the furnace, it could permanently damage the furnace or crusade a fire.
In one case the rail are built and installed, the coil can exist installed into the supply plenum. If the plenum is larger than the coil, a sail metal pan must exist built with an opening provided below the gyre. This opening needs to mirror the lesser opening of the coil for proper airflow from the furnace going through the coil.
If the opening is not big plenty, or too much air goes around the gyre instead of through it, the coil will freeze into a block of ice. This can impairment the ringlet and crusade a refrigerant leak by cracking the tubing conveying the refrigerant.
Once those are installed, the final step is edifice the front of the plenum. It is possible to build an access panel door into the plenum to comprehend the scroll. This is non required by any lawmaking or manufacture specification, so it would be upwards to the installer. In all scenarios, the cover must accept holes provided for the refrigerant lines, and then also for the condensation lines to be continued.
The blazon of coil chosen is more often than not 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 lawmaking and industry specifications to the existing duct system, can drain properly, and is sealed from air leaks, you volition enjoy the same level of comfort. There is no difference in warranty or life expectancy between either type of coil.
Installation of the New Copper Refrigerant Lines (Line Set)
The new refrigerant line set is a combination of 2 individual copper lines. One line is e'er bigger than the other and is insulated. The bigger line is called the suction line, and the little 1 is called the liquid line. They come packaged together, rolled in a coil. It is available in multiple selections of lengths, from 15-50 feet. You volition rarely need more than l feet in a residential home.
The key is installing the line with as few bends and turns as possible. When these bends are necessary, the soft copper tin exist bent by manus or a tubing bough.
Information technology's common to install the line set as close to your abode'due south beams and ductwork as possible. Information technology'due south also recommended that y'all secure the line every 4-vi anxiety. Plastic or copper strapping is common. Metal straps or clamps can exist used, but it's important to protect the copper wiring if the clamps touch them.
If yous don't properly protect the line, information technology can corrode. Galvanic corrosion (also chosen bimetallic corrosion) is the breakdown of metal when two dissimilar metals come up into contact. This does take some time to occur. Nevertheless, if allowed to occur, information technology could eventually reduce the integrity of the copper refrigerant line over time until information technology causes a leak.
Subsequently the hangers are installed, the line prepare tin can now be put in place. Typically, an installer will start with the suction line and curlicue out one end a few feet, leaving the remainder of the coil in a coil. They so push the unrolled department through a hole drilled through the ring board of the house to the outside, near the air conditioner. Enough of the line is pushed out to reach the service valve of the air conditioner.
Somewhen, the installer will connect this line to the air conditioner itself. The hole size volition be betwixt ii-2.v" in diameter, depending on the type of line set up beingness used.
After the line is exterior past the air conditioner, the line is secured by hangers near the hole then another hanger back a couple of feet. The line is then carefully uncoiled and formed along the floor joists up against the trunk line ductwork or a beam, every bit straight every bit 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 outside to the new indoor evaporator coil on top of the furnace. Afterwards the suction line has been installed and secured, the smaller, liquid line is run forth the suction line, secured in the same hangers.
A line gear up should be new, installed as one slice, gratis from whatever sharp bends or kinks, and secured with an appropriate hanging organisation.
There will also exist a small, low-voltage control wire that runs from the furnace forth the line gear up to the air conditioner outside. The small existing wire coming from the thermostat to the furnace sends a low voltage betoken to the air conditioner to plough on and off when a phone call for cooling is needed or has been satisfied.
Setting the New Air Conditioner Condenser
Then far, we've set the pad, leveled it, and our refrigeration lines and electrical disconnect are gear up to be wired into the new air conditioner condenser.
Removing the new air conditioner and setting it on the pad is step i. Later on uncrating the unit, a good installer will audit for any damage. Sometimes panels or coils will go damaged in transit. Whatsoever damage should be reported to yous immediately.
Fire & Ice Heating and Air conditioning runs multiple inspections on equipment, both when it arrives and when it'southward installed, to ensure it is in working club.
If in that location is a paring, that doesn't necessarily mean there is whatever harm that will affect performance. However, you e'er accept the right as a customer to not have the damaged unit of measurement and ask for another one.
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 point for the line set, and besides isolates the refrigerant contained inside the unit. Service valves too allow for the outdoor condenser portion of the air conditioner to be isolated from the indoor coil and line set for time to come service or repair needs when needed.
Isolating the refrigerant keeps yous from having to replace information technology with all new refrigerant in instance of a repair in the future.
After the line prepare 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 metal and argent 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 menses to weld the connection.
If this process is completed properly, the copper line fix, 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 system. They serve 2 main functions. The well-nigh of import function of a filter drier is to absorb moisture. The second is to provide physical filtration.
When installing a new air conditioner condenser, yous must always install a liquid line filter drier into the refrigeration system. Virtually new air conditioner condensers come with a liquid line filter drier for you to install.
Manufacturers recommend the filter drier be installed close to the expansion valve (TXV) at the indoor coil, as oftentimes as possible. This keeps the TXV protected and keeps the filter drier from being exposed to weather where it could rust.
At that place is besides an arrow for flow direction. This arrow must e'er be in the direction that is going into the indoor whorl.
Any contaminants in the refrigeration organization are harmful. Water or moisture is the worst.
Moisture enters the organization in different ways. If a system is not evacuated properly, moisture will be in it. Wet can also come up from leaks or motor windings. The h2o tin can cause corrosion and create failure in metallic parts.
Water or moisture can also react with the oil in the refrigerant system. This is called hydrolysis, which forms acids in the system. Acids, moisture, or any other contamination in the lines will exist extremely unsafe to the integrity of your new air conditioning system.
All good HVAC companies have strict processes in identify for their install teams to preclude failure equally much as possible. Whatsoever time a refrigerant line is open to the temper, information technology is vital to install a new filter drier. This is true of installations too as service repairs.
This brazing process is the aforementioned for connection to the indoor evaporator roll. This, 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 flame outside and inside the home. It can be dangerous to the installer, the homeowner, and the dwelling house, causing permanent damage without proper training. Following manufacturer and safety guidelines is fundamental.
Preparing the line set up for refrigerant in this way is the most important step in ensuring the safety and efficiency of your air conditioner.
Sadly, this process is unknown or not followed to most install teams. Not all companies are equal in training or processes, and many contractors lack the proper equipment. A good HVAC company will have all the tools and processes needed to install the air conditioner professionally and thoroughly.
After the line gear up is fitted properly into the service valves and indoor curlicue, rut protection needs to be applied. Heat protection can be a rut-absorbing paste, moisture towels, or rags. Anything that would go along the heat spreading into either of the coils is adequate. The service valves on the outdoor condenser contain safety O-rings that will melt 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 prepare, losing the factory charge.
From the factory, the air conditioner condenser is prepared, cleaned, and the refrigerant is added. If the refrigerant is exposed before the process is completed, information technology becomes contaminated, along with the condenser coil. If this footstep is performed improperly, all the refrigerant would need to be recovered and the condenser coil would need cleaned and prepared once again before whatever refrigerant could exist added.
Nigh indoor coils have a metering device called an expansion valve that will be damaged if non protected from the rut during brazing. If these become likewise hot, or any contaminants are introduced, the expansion valve volition be compromised and fail to operate.
Once the oestrus protection is completed, a tank containing a gas called dry nitrogen is hooked upwards to a regulator and maybe a manifold estimate prepare. This allows the nitrogen to be purged while brazing. The nitrogen protects the within of the copper tubing from oxidizing during brazing. The damage will non always be present immediately.
The HVAC industry requires brazing with nitrogen every time to forestall this impairment.
Brazing with nitrogen, when done properly, will give the system maximum opportunity for functioning, reliability, and dependability. Later on the organisation is brazed in both the indoor and the outdoor components, it must be checked for leaks using the aforementioned dry nitrogen, up to a specific amount of force per unit area. Using the dry nitrogen to pressure test the organization achieves three things:
- Information technology's a preliminary leak test.
- The dry nitrogen will choice up wet.
- It will also purge some contaminants out of the system upon its release.
It is very important to verify with the installation manual provided by the manufacturer what they recommend for force per unit area. Almost systems are designed for 150 PSI when testing.
If there is too much pressure level added, problems can occur. If the force per unit area is too high for the O-ring seal, for example, the nitrogen volition drain into the refrigerant, contaminating it.
In this scenario, all the refrigerant contained in the condenser from the mill will exist compromised and will take to be recovered, and then the coil cleaned and prepped for more than refrigerant.
If the preliminary leak test with nitrogen holds for a minimum of 10 minutes, then it's fourth dimension to move on to the adjacent crucial step: vacuuming the arrangement.
Typically a system is vacuumed to a minimum of 500 microns. The manufacturer's recommended vacuum is constitute in the installation manual. Refrigeration systems are designed to operate with just oil and refrigerant flowing through them.
Our atmosphere is made upwardly of oxygen, nitrogen, and moisture. These are enemies to the organization'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 accomplished through the vacuum process when installing the air conditioner. The vacuum process tin take no less than 30 minutes and up to an hour or more than depending on the size of equipment coils and length of line set.
Failure to provide a dry, moisture-free atmosphere before introducing the refrigerant into the rest of the system will in all cases promote an inconsistent operation, and eventually permanent failure of the organisation.
To achieve a successful vacuum on an air workout arrangement there are several central tools and equipment that must be used:
- A reliable vacuum pump
- A micron gauge
- Manifold and hoses
- Vacuum rated cadre removal tool
The vacuum must attain 500 microns or less in the arrangement and concord the vacuum for this to be successful. This is also the second and last leak exam. If a system does not hold a vacuum, then there is a leak somewhere.
Once a proper vacuum is accomplished and has proven to agree, the system is ready to have refrigerant introduced to it. Refrigerant is the only product that tin "break" the vacuum. If hoses are disconnected from the arrangement before the refrigerant has been released into the organization, the atmosphere volition break the vacuum. If this happens, the vacuum procedure must be redone before refrigerant tin be introduced.
With the hoses still connected to the service valves of the air conditioner, the refrigerant is released into the system, breaking the vacuum by opening the suction-side service valve first followed by the liquid side second.
Installation of the New Loftier- and Low-Voltage Wiring
For the air-conditioning system to operate, the high- and low-voltage wiring must be reconnected. Using the existing ability supply from the electric panel inside the home, the installer will mountain 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 it is beingness mounted to.
There are two main types of disconnect boxes. Ane is fused and the other is non-fused. They are both appropriate to use outdoors. A fused disconnect allows the proper overcurrent protection required past the manufacturer. This blazon is most common and required when the main circuit from the panel exceeds the maximum required overcurrent protection. It also allows for boosted prophylactic to the air conditioner condenser.
A non-fused disconnect may be used only in cases where the breaker matches identically to the manufactures listed maximum overcurrent protection. In that location is a minimum and a maximum required overcurrent protection. You lot must be within these guidelines. The organisation will not pass the code requirements if they are not.
For example, if you have an existing 40-amp excursion that supplies the disconnect, merely the listed overcurrent protection is only 30 amps, you lot must utilize the fused disconnect and install 30-amp fuses with it to properly protect the air conditioning condenser. If the amperage from the breaker matches the maximum or the minimum overcurrent protection, a not-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 console) and "Load" (the whip that takes ability to the air conditioner). This allows the pull inside the service disconnect to intermission or disconnect the power supply to the air conditioner without having to close the breaker off from the main panel.
Because the air conditioner is outside, information technology would be cumbersome to run in and out of the business firm to turn the ability on or off in case of emergency or servicing. The service disconnect is required past state and local code requirements.
There are besides requirements for placement of the air workout condenser. It boils down to making sure there is proper accessibility. All the electrical connections should be made co-ordinate to the NEC (National Electric Code). The depression-voltage control wire is connected straight into the ac condenser at the proper locations according to the air conditioning condenser installation instructions.
This is the "signal" from the control lath 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 cycle co-ordinate to the parameters set regarding temperature and humidity inside the dwelling. The low voltage wiring is continued to the command board inside the furnace on designated terminals.
Installation of the Condensate Drain Line
The moisture removed from the dwelling house during the cooling procedure travels down a plastic PVC pipe. It must be connected to the principal side of the evaporator coil. The evaporator coil has a primary and a secondary bleed location. The primary condensate drain line will travel from the indoor evaporator ringlet to an advisable floor drain or condensation pump.
A condensation pump is used where a proper flooring drain does not be in the domicile. There are too other reasons where a condensate pump is required or is benign to install. The important thing to remember if a condensate pump is used is that it must exist serviced a minimum of twice a yr to maintain proper performance.
Any condensate tubing or piping should exist secured and glued with the proper cement. A trap and an overflow safe switch must also be installed in the condensate arrangement. This is to protect the equipment and the area from flooding due to a restriction. The safety overflow switch is connected to the secondary port on the indoor evaporator coil and wired into the furnace control to shut downwardly the system when it is tripped.
Startup Commissioning Process
The startup and commissioning (testing) procedure is done afterward the system is completely installed and ready to operate. The system is turned on and must run for 15-20 minutes. This will let the refrigerant to flow through the organization and starting time the ac process.
Upon initial startup of the new ac system, the business firm should be very warm or take a "load" with a warm plenty temperature inside the habitation to allow for the minimum potential to charge the system accurately. A temperature above 75 degrees Fahrenheit is recommended in most cases. This allows the components in the air workout system to be in full functioning to let maximum cooling potential during charging.
Sometimes running the furnace to rut the firm is a common do to provide the necessary load on the home. Later 15-20 minutes of operation, the system can now be commissioned.
A good installer volition check the thermostat operation, arrangement sequence of operation, and multiple other areas. While the system is operating, the following information is of import to collect to ensure proper operation within manufacturers' specifications:
- Suction and liquid line pressure
- Suction and liquid line temperature
- Superheat
- Subcooling
- Outdoor ambience dry seedling temperature
- Indoor ambient dry bulb temperature
- Indoor wet bulb temperature
- Render air temperature
- Supply air temperature
- Static pressure from return side, supply-side, and total static readings
- Temperature driblet calculated
- Loftier voltage current reading
- Amperage on the blower motor, outdoor fan motor, and compressor
- Low voltage electric current reading
- Line set length
- Amount of refrigerant, if whatever, added to the organisation
- Distance to a higher place or below the outdoor unit is in relation to the indoor coil
- Blower speed tap/CFM recorded
This is the bones list of the proper data that should be known and recorded. This is the only mode to know for sure how the system is operating and if it is within manufacturing specifications. If whatever of these practice not fall within manufacturer specifications, your system may non be warrantied by the manufacturer.
Commissioning is of import for several reasons. For you, the peace of listen that you lot are receiving a properly set up and adapted organization for maximum comfort, efficiency, and dependability. It besides ensures the manufacturer'south warranty volition be in total event. The benefit to the company installing the system is that information technology gives a baseline of operational performance in case whatever problems arise after.
It besides gives the installing team confidence that before they leave, your organization is in perfect functioning. It is very mutual for systems to be installed and started upwards without much consideration for proper commissioning.
Unfortunately, many companies plough it on and walk away the moment cold air is coming through the vents.
Proper commissioning is a specific procedure that requires training and special equipment to perform the process correctly. It also requires additional time and labor on a job site. Commissioning is the only way to know for sure exactly how well your arrangement is operating.
Why would a company skip this step, and so? In a word: toll. 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 safe, and your condolement.
A good HVAC contractor volition have trained installation teams that will properly commission your air conditioner before they leave the job.
Clean upwardly and Closing Process
The cleanup process is comparatively elementary. All material and sometime equipment should exist loaded upward and taken away from the home. The floor protection should exist rolled up last, keeping all debris from the installation inside the drop cloth and out of your home.
All areas should be swept and costless of any materials or debris. You lot should expect to see the surface area in the same condition in which information technology was found.
A walkthrough of what was done during the installation should exist completed with y'all. Going over safety, maintenance, warranty, and all special instructions are expected.
As a last mechanical stride, a locking cap should be placed on the outdoor portion of the unit. This cap can but be unlocked with the correct key. This is to forbid tampering with your equipment, and also to prevent theft of the refrigerant. This cap is often a specific color, which will let a technician know which blazon of refrigerant your system uses.
A visual inspection of the piece of work completed should also exist offered. Finally, a review of the commissioning and thermostat operation. After the final walkthrough, final signatures and payments are collected.
Installation Completed Professionally
The task is now complete!
The process may seem long and complicated, but in the hands of a skilled installation squad, the unabridged process should be second nature.
Don't cut corners with installation. Your money and condolement are at gamble if any of these steps are skipped. Knowing the full procedure will allow you to hold companies answerable when you decide to invest in a new air conditioning system. The result will exist a comfortable, efficient, long-lasting production.
