Air Conditioner Installation is a major project requiring careful planning, proper tools, and adherence to manufacturer guidelines. It’s also one of the most important projects a homeowner can take on, and mistakes can be costly.
Incorrectly installing an air conditioning system can lead to shortened equipment life, inefficiency, discomfort, and high energy costs. An experienced HVAC specialist should be hired to perform all steps of the process and ensure a proper air conditioning system is installed for maximum comfort and efficiency.
The first step is to assess the space and determine a suitable air conditioner. The most common choice is a domestic or “split-system” model that includes an indoor and outdoor unit with refrigerant pipes connecting the two. The contractor will also determine if there are any restrictions to placing the unit, such as a roof leak or an issue with your home’s ductwork that may require modification.
Once the space is cleared and prepped, the installer will connect the refrigerant lines to the new air conditioner. It’s critical that all connections are made properly and with the right tools to avoid damaging the new system.
All individuals handling refrigerant must have a valid EPA (Environmental Protection Agency) certification. This will be verified at the time of installation, as well as during the commissioning process.
The installation team will mount the indoor unit, using a mounting bracket that fits the size of the window. They will use a level to verify the bracket is straight, so the AC can sit in the window without moving or shifting. They will then drill holes through the mounting plate and the wall stud, and fasten the unit to the mounting bracket with screws.
A drain line is connected to the air conditioner and routed to an appropriate discharge location, such as a floor drain or condensate pump. The installer will also connect the electrical wires and check their length to ensure they are long enough to reach the breaker box and power cord.
Finally, the new outdoor unit is mounted on a composite pad, which is much more durable than concrete and will last the lifetime of the air conditioner. It’s also safer, as concrete pads are more likely to crack and shift over time.
The contractor will then run the outdoor unit for up to 20 minutes to test sequence of operation, thermostat function, and a range of settings. The installer will also discuss operating parameters and demonstrate the maintenance process.
While this comprehensive air conditioning installation process may seem lengthy, a professional technician will work quickly and efficiently to ensure the job is done correctly. They will also provide a thorough commissioning process, which is often overlooked or skipped by homeowners. This important step ensures that the system is functioning as intended and that your home is comfortable, efficient, and safe.
