Before diving into repairs, it’s essential to understand the basic components of your air conditioning system. Most residential AC units consist of two main parts: Phoenix Air Conditioning Repair Ac Repair Man Near Me 24 Hour Air Conditioning Service Near Me Air Conditioning And Heating Services

• The Outdoor Unit (Condenser): This unit, typically located outside your home, houses the compressor, condenser coil, and fan. Its primary function is to release heat from the refrigerant.
• The Indoor Unit (Evaporator): This unit, often located in your attic, basement, or closet, contains the evaporator coil and blower fan. It absorbs heat from the air inside your home, cooling it down.

These two units are connected by refrigerant lines, which circulate a special chemical called refrigerant. The refrigerant absorbs heat from the indoor air, carries it to the outdoor unit, and releases it. 24 Hvac Service Near Me 24 7 Hvac Service Commercial Ac Service Near Me Heating And Ac Companies Near Me
