Air conditioning installation is a complex project that requires specialized training and the right tools to complete correctly. Hiring an experienced HVAC company ensures that your new AC system is properly sized and installed, ensuring optimal comfort and energy efficiency. During an in-home consultation, an HVAC contractor will assess your home and recommend the right system for your needs. Once you have selected a system, the company will order it for your home and schedule an installation date. During this time, you will want to make sure that the unit is delivered to the installation site in good condition and that you have prepared for the installation.
Depending on the type of AC you select, the installation process may take several days or even weeks. This is because it will take time for the air conditioning unit to be delivered, for the contractor to schedule an appointment with you, and for the installation team to get the unit up and running. A professional installer will also conduct a walk-through of your home to make sure the air conditioner is located in the best possible spot. If you are installing a wall-mounted AC, you will need to make sure that the mounting location is sturdy and stable, at least 2.1 m above the ground. Additionally, the location should be free of any obstructions that could restrict air flow. Finally, the mounting location should be at least 3.3 feet (1.0 m) away from antennas and cables used for televisions, radios, intercoms, home security systems, or telephones. These can cause electrical interference that affects the performance of your new air conditioning unit.
If you’re installing a central air conditioning system, your HVAC contractor will need to inspect and repair existing ductwork. This may include sealing leaks, resizing or rerouting ductwork to optimize airflow and eliminate hot and cold spots throughout your home. The technician will also install a new thermostat, if you choose to upgrade from your current model.
The installation team will begin the project by draining the refrigerant from your old system, using a recovery machine to safely remove the substance from the system. This is a critical step to prevent environmental hazards, including the illegal venting of refrigerant into the atmosphere. Then, the team will disconnect all the electrical wiring, remove the old power conduit or “whip,” and install a new one.
Before the installation of your new AC unit, the team will prepare the mounting area by spreading a pad for the outdoor unit to sit on. Then the team will mount the unit to the pad, level it, and connect the evaporator coil and blower. Finally, the technician will test the system to make sure it is operating properly and connect the new ductwork to the new unit.
Your HVAC technician will explain any basic maintenance tasks you can perform, and can answer any questions you have about your new system. You will then be able to enjoy the cool comfort of your new air conditioning system!
