Your furnace and air conditioner work together to keep your home comfortable. Both units use components of your HVAC system, so upgrades to either can benefit the other and improve energy efficiency overall.

Here’s how:

  1. Your furnace and AC use the same air blower.
  2. Your home thermostat activates, controls, and shuts off both devices.
  3. The furnace and air conditioner work together to clean and condition air before recirculating it throughout the house.
  4. Both systems help maintain temperature and humidity.
  5. The AC Evaporator transfers excess heat and humidity from inside to outside the home. It uses the same system as your furnace, so an issue with the overall system can cause it to freeze.

Understanding how your HVAC system works can help you work out a maintenance schedule, adjust your thermostat programming and improve energy efficiency. It can also help you troubleshoot issues when working with a qualified HVAC technician to ensure they run safely and efficiently.
