Air Conditioning Installation is the process of installing an air conditioner and associated components. This can be done by a professional, or the homeowner may choose to do some of the work himself. It can involve the actual unit, a rooftop support arrangement, or interior work, including ductwork and thermostat. An HVAC technician is a good choice to perform these tasks, since they have extensive training and experience with a variety of brands and types of equipment.
The first step is preparing the site. This includes cleaning the area and ensuring that it can support the weight of the new unit. It also involves removing any debris that could interfere with the installation. It is often recommended that the new AC unit be set on a composite pad rather than a concrete one, as a concrete pad can crack and shift, causing problems for the unit. The installer can also install a vapor barrier, which is an inexpensive way to protect against water leaks from the unit.
Next, the installer will mount the indoor unit in the window frame. This will include removing any storm window frames and ensuring that the window is free from obstructions, such as branches or shrubbery. It is a good idea to use an air conditioning company that offers pre-installation evaluations, as these can help homeowners avoid the added cost of unanticipated problems that can add up quickly.
After mounting the indoor unit, the installer will close and secure the window sash. This will prevent hot air from escaping and cold air from leaking out. He will then extend accordion-style side panels and attach them to the window frame using clips or screws. This helps to seal the window and improve the performance of the air conditioner.
Depending on the air conditioner, there may be various wiring connections to make, including a wire connection from the compressor to the control panel and a line from the condenser to the evaporator coil inside your home. The installer will also connect a power cable from the electrical panel to the outdoor unit. This will include running the wires through a new service disconnect box, which is mounted on the wall outside of the house.
Once all the connections are made, the installer will run a new refrigerant line from the compressor to the indoor evaporator coil. He will use hangers to keep the lines in place and will make sure that just enough line is pushed through to reach the service valve on the air conditioner. The technician will then connect a low-voltage control wire from the thermostat to the air conditioner.
Once the connections are complete, the technician will test the system to ensure that it is working properly. This includes a thorough evaluation of the air ducts to look for leaks. If any repairs are needed, the technician will let you know how they should be performed and can schedule a follow-up maintenance appointment at your convenience.
