Testing Your Air Conditioner

I received this helpful tip in email from 'Appliance Zone'To do this test, the outside temperature needs to be above 80 degrees Fahrenheit and your A/C unit needs to have been running for at least 15 minutes. Also be sure that you have a clean air filter in place.

Place a room thermometer on the supply register closest to the inside cooling equipment. Wait 5 minutes then check the temperature reading. Then do the same at the return register.

The air coming into your house should be 14-20 degrees cooler than the air going out. If your air conditioner isn't cooling up to those parameters, it may need a tune-up."
I've bought several parts from these people. I found them to be trustworthy. Thought I'd pass this along to anyone who's interested.
