Understanding the Role of the AC Fan 24 Hour Ac Company Commercial Hvac Service Near Me Ac Fixing

Before diving into repairs, it’s essential to understand the different types of fans and their functions within an AC system. Generally, AC units utilize two primary types of fans: Emergency Heating Repair Near Me 24 Hour Hvac Service Near Me Heating Repair In My Area

• The Blower Fan (Indoor Fan): This fan is located inside the air handler unit, typically found in your attic, closet, or basement. Its primary role is to draw warm air from your home, pass it over the evaporator coil (where the refrigerant absorbs heat), and then distribute the cooled air back into your living spaces through the ductwork. 24 Hour Emergency Heating Service 24 Hour Heating And Cooling Service Near Me Air Conditioning Specialist Near Me

• The Condenser Fan (Outdoor Fan): This fan is located in the outdoor unit, the large metal box usually placed outside your house. Its function is to draw air across the condenser coil, where the refrigerant releases heat, allowing the system to dissipate the heat it has absorbed from your home.

Both fans are crucial for the proper operation of your AC system. If either fan fails, the AC unit’s cooling performance will be significantly impacted. 24 Hvac Service Near Me Ac Repair Companies Heater Repair Services
