For central air conditioners

A central air conditioner contains two main parts – a condenser unit located outside the house and an evaporator coil mounted inside. Both these units are sealed and hence, their internal workings should be serviced by authorized personnel.

However, you can do some preliminary maintenance by cleaning the evaporator as described in the following steps:

1. Remove foil-wrapped insulation at front behind which is the access plate. Unscrew and remove it. Clean entire underside of evaporator unit with stiff brush. You can slide out the unit if it’s difficult to reach.

3. Put unit back into place, reinstall plate and tape the insulation back.Dallas HVAC Attic Tent Continue reading →
