Central air conditioners have two separate components: the condenser and the evap­orator. Located  outside the house, the condenser unit is usually on a concrete slab. The evaporator coil is mounted in the plenum or main duct junction above the furnace.  Most  Utah County central air conditioners  are connected to a home’s forced-air distribution system. The same motor, blower, and ductwork used for heating are used to distribute cool air from the air conditioning system. When a central air conditioner is operating, hot air inside the house flows to the furnace through the return-air duct. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the house. When the air conditioner works but the house doesn’t cool, the problem is probably in the distribution system.

The evaporator and the condenser are sealed so a professional Lehi HVAC technition should be called for any maintenance other than routine cleaning. Central air conditioners should be professionally inspected and adjusted before the beginning of every cooling season.
