Cooling (and heating) your home is one of the most costly portions of your energy bill. The Family Handyman has a tip for ensuring your air conditioner works as efficiently as possible.
If your air conditioner isn’t cooling the house quickly enough, it may need repair. Here’s how to test it:
To determine whether your air conditioner needs a tune-up, perform this easy test when your AC unit has been running for at least 15 minutes and the outdoor temp is above 80 degrees F. With a clean air filter in place, set a thermometer on the supply register that’s closest to the inside cooling equipment. Keep it there for five minutes and note the temperature. Do the same thing at the return vent. The air coming out should be 14 to 20 degrees cooler than the air going in. An air conditioner that’s not cooling to those levels could be low on refrigerant or have leaks. A unit cooling more than 20 degrees could have a severe blockage.
If you aren’t sure whether your air conditioner is operating at full efficiency, give this test a try to find out. Hit the link for more tips on saving energy in the summer.
