Professional AC Installation Process
The installation process involves several key steps that require precision and expertise. Each phase builds on the previous one to create a complete cooling system for your home.
Removing Old Equipment and Ensuring Proper Disposal
We start by safely disconnecting your old air conditioning system from all power sources. This prevents electrical hazards during removal.
Our team carefully removes refrigerant from the old system using specialized recovery equipment. This step protects the environment and follows EPA regulations.
We disconnect the refrigerant lines and electrical connections from both the indoor and outdoor units. Each connection point gets properly sealed to prevent contamination.
The old condenser unit comes out first, followed by the indoor air handler or evaporator coil. We protect your floors and walls during this process.
We dispose of all old equipment according to local environmental laws. Many components get recycled, including metals and refrigerants.
Installing the Outdoor Condenser Unit
We select the best location for your new condenser unit based on airflow requirements and local codes. The spot needs proper clearance on all sides.
A concrete pad or mounting brackets provide a stable foundation. We ensure the unit sits level to prevent vibration and operating problems.
Our team positions the condenser away from bedrooms and neighbor properties to reduce noise. We also consider service access for future maintenance.
The unit gets secured to its mounting surface using manufacturer-approved hardware. This prevents movement during operation and severe weather.
We check that the condenser has adequate electrical supply nearby. The disconnect box gets installed within sight of the unit for safety.
Setting Up the Air Handler and Indoor Components
The indoor air handler or evaporator coil goes in your chosen location, typically an attic, basement, or closet. We verify adequate space for service access.
We mount the unit securely to prevent vibration and ensure proper drainage. The condensate drain gets connected to an appropriate disposal location.
Ductwork connections get sealed properly to prevent air leaks. We use mastic sealant or metal tape, not standard duct tape.
The air filter housing gets positioned for easy access during regular maintenance. We show you how to change filters properly.
We install the thermostat in a central location away from direct sunlight and heat sources. The wiring runs back to the air handler through walls or conduit.
Connecting Refrigerant Lines and Electrical Connections
Refrigerant lines get sized according to your system's capacity and the distance between units. We use proper insulation to prevent energy loss.
We run copper lines through walls or outside your home, securing them every few feet. Sharp bends get avoided to maintain proper refrigerant flow.
All joints get brazed using nitrogen to prevent oxidation inside the lines. This creates strong, leak-free connections that last for years.
Electrical connections get made according to manufacturer specifications and local electrical codes. We use appropriate wire gauges for your system's power requirements.
We test all connections with meters before energizing the system. The electrical disconnect gets properly labeled for safety.
A final pressure test ensures no leaks exist before adding refrigerant. We evacuate the lines and charge the system to exact specifications.
