This Simple Visual Inspection Procedure Can Disclose Damage or Operating Problems

Schematic of an air conditioner compressor unit showing inspection points (C) Carson Dunlop AssociatesThe (usually) outdoor half of a typical air conditioning system is a unit containing the refrigerant compressor and condensing coil. The air conditioning compressor motor is a pump which draws heat laden refrigerant gas from the building's indoor components (evaporator coil and air handler), and compresses the low pressure refrigerant gas to high pressure and higher temperature.

The diagnosis and repair of various defects in the air conditioning compressor/condenser unit are discussed in detail using the links provided at the left of this page.

Here is a little visual inspection checklist that any homeowner or home inspector can perform.
