Useful Tips For Homeowners

 A good working a/c system should produce about 20* F of cooling or heating (heat pump).

 

 

 

Supply Air

1.  Measure the temperature of the air blowing out of the register with a thermometer(stem, or laser). Eg. 60*F

Return Air

2. Then measure the air going into the Return grill(with clean filter), with your thermometer.  Eg. 80*F

System

3. Finally subtract the Return Air *F from the Supply Air *F to get your air split. Return - Supply= 18-20*F 

If your reading is Less than 18*F, you are Low on refrigerant. Which requires Professional help to top off your system.  Call 602-433-9241
