If your home’s central air conditioning system is like most, it’s a split system. That means it has indoor and outdoor components: an indoor air handler and evaporator coil connected to the ductwork system, and an outdoor condenser cabinet. You pay more attention to the indoor parts, because you can hear the operation of the blower fan. The outdoor unit is a functional object that’s placed out of the way where it doesn’t detract from the exterior of the house.
We recommend you pay some attention to the condenser, however, particularly at this time of year. If the condenser becomes dirty or the area around it congested with branches, leaves, dirt, and other obstacles, the AC’s performance will suffer. We’ll explain why.
