AC temperature differential test

A-C temperature differential test: Generally the temperature of the return air entering the air conditioner and the cooled air leaving the air conditioner should differ by about 14 to 22 degrees Fahrenheit Below 14 degrees may mean the unit needs freon or other gasses. Above 22 degrees may mean the filter is dirty or the air flow is somehow restricted causing it to pass over the cooling coils too slowly. This may lead to excessive sweating and moisture. The final test for differential must be done as close to the evaporator coils as possible to eliminate duct temperature interference.

Heater toxic gas test: Flame distortion and flame color test: Heating equipment clearance: Vent system review:
