Understanding Your AC System

Before any Fontana air conditioner repair, it helps to understand your AC system and its key components. 

  • Compressor: Circulates refrigerant and transfers heat outside
  • Condenser Coil: Releases heat from your home into the outdoor air
  • Evaporator Coil: Absorbs heat from indoor air
  • Refrigerant Lines: Copper tubing connecting indoor and outdoor units
  • Air Handler/Blower: Circulates cooled air through ductwork
  • Thermostat: Controls temperature settings
  • Air Filter: Traps dust and debris to protect the system and air quality

Don’t forget—it’s also wise to familiarize yourself with California’s SEER2 efficiency standards. 

When upgrading your home to newer systems rather than repairing an older system, you can save money by reducing energy costs.
