Understanding the Split System AC 24 Hour Ac Company 24 7 Hvac Service Heating And Ac Service Near Me

Before diving into repairs, it’s essential to grasp the basic components of a split system AC. It primarily consists of two units: Emergency Heating Repair Near Me Ac Repair Company Near Me Air Conditioning And Heating Services Near Me

• Indoor Unit (Evaporator Coil): This unit is located inside the building and houses the evaporator coil, blower fan, and air filter. It’s responsible for absorbing heat from the indoor air, cooling it down, and circulating it throughout the space.
• Outdoor Unit (Condenser Unit): This unit is located outside the building and contains the compressor, condenser coil, and fan. It’s responsible for releasing the heat absorbed by the indoor unit to the outside environment.

These two units are connected by refrigerant lines, electrical wiring, and a condensate drain line. The refrigerant, a specialized fluid, circulates between the units, absorbing and releasing heat to provide cooling. 24 Hour Emergency Heating Service Air Conditioning Repair Companies Near Me Heating Ac Service Near Me
