Understanding The Air Conditioning Installation Process

HVAC systems are popular in most American homesteads. The US Energy Information Administration reports that 87% of American homes use air conditioning systems. HVAC systems use thermal manipulation to condition air and ensure homes are habitable. The popularity of HVAC systems in America is reflected in the rapid growth of the HVAC industry. Moreover, HVAC manufacturers continually find ways to enhance HVAC units' efficiency, productivity, and longevity to entice more consumers to purchase the systems. Given the climate and weather changes experienced globally, more residential homes will require air conditioning systems for safety and comfort. Below are the procedures professional HVAC contractors use during residential air conditioning installation.

Step #1: Resize the Duct

Most residential homeowners who perform DIY HVAC installations do not understand the importance of duct sizing to HVAC efficiency. Duct sizing depends on numerous factors, including airflow, static pressure, friction loss, and the home's size. HVAC systems are designed to work intricately with all its parts to ensure efficiency. Thus, a wrong size duct affects how well an air conditioning system works. Qualified HVAC contractors first cut and resize the duct to ensure it fits the HVAC system's requirements before proceeding with the residential air conditioning installation process.

Step #2: Indoor and Condenser Unit Placement

The second step during residential air conditioning installation entails placing the indoor evaporator. A qualified HVAC contractor hooks the evaporator to the duct before connecting it to a drain line; the drain line is responsible for condensate drainage. The HVAC contractors connect it to a coolant line leading to a condenser unit located outside. The HVAC contractors use an outdoor cabinet to house the air conditioning system's condenser coil and compressor. The cabinet is secured to a solid foundation to minimize accidents and tampering. Finally, the contractors connect power lines and the coolant to the condenser unit. HVAC contractors have protocols ensuring the condenser unit is placed correctly during residential air conditioning installation, mitigating inefficient airflow.

Step #3: Electrical and System Checks

Generally, HVAC systems consume a lot of power when running the compressor. Thus, HVAC contractors must establish that all electrical connections are correct to avoid tripping the circuit breakers. After inspecting the electrical connections, HVAC contractors connect and charge the refrigerant before completing the residential air conditioning installation process. The HVAC contractors should run the air conditioning system while checking for thermostat control, proper airflow, and cooling power. The test runs detecting inefficient heating or cooling, allowing timely system diagnostics and remedies.


Residential air conditioning installation requires expertise that most homeowners lack. Thus, homeowners should consult qualified professionals rather than perform shoddy DIY installations.
