· Type of refrigerant, there are two common types, R22 and R410.
· Outdoor temperature at the time the A/C is being serviced.
· Clean and lube the furnace motor. The furnace motor circulates the cool air and needs to be serviced.
· Clean or replace the furnace filter. A clean filter is vital for the air conditioner to operate properly and efficiently.
· Oil the condenser motor. This is the fan motor on the outdoor unit.
· Check condenser motor and compressor amps. High amperage draw indicates a problem.
· Wash the condenser coil. This coil is part of the outdoor unit.
· Check for spiders in the electrical contacts. Sounds strange, but those little buggers cause problems.
· Check refrigerant levels. A tune up does not include adding refrigerant. If your system is low, expect additional charges. Heads up, refrigerant prices have skyrocketed in recent years.
· Check temperature differential. This is the temperature drop from the room temperature air to the air temperature coming out of your registers. Normally it’s an 18 to 21 degree difference. More or less may indicate problems.
· Check Superheat. This indicates how much heat is being removed from the home.
· Check thermostat settings and calibration.
· Confirm the supply air and return air vents are not covered or blocked by furniture.
