Understanding Your AC System

When you understand how your AC system works, you can better understand the repairs or replacements that might be necessary. To help, familiarize yourself with the cooling system’s key components below:  

  • 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

It’s also important to understand that AC replacements in Corona, CA, may help you save money from California’s SEER2 efficiency standards. 

When upgrading your home to newer systems rather than repairing an older system, you’ll reduce overall energy costs.
