Does Your AC Evaporator Unit Require Maintenance?
Typical residential air conditioning systems have three critical components: the condenser, evaporator, and air handler. If your home uses forced air heating, both HVAC systems likely share the same air handling unit. You probably already know that you need to change your air conditioning filter periodically, but it's not the only part of your system that requires regular maintenance. The evaporator coils are the magic that allows your air conditioner to deliver cool air.
