Q. Why does my air conditioner require a CheckMe!^TM Engineering Performance Evaluation?
A. U.S. Environmental Protection Agency (EPA) research studies confirm that "2/3 of all American home central air conditioning systems are performing significantly below the manufacturer's specification."

Q. Do I need a CheckMe!^TM if my air conditioner seems to be operating fine?
A. Yes. Simply because there is cool air blowing from your house air ducts does not mean you're getting all the cooling air conditioned comfort you're paying for.

Q. What kinds of things can cause my air conditioner to operate inefficiently?
A. Improper refrigerant charge and air flow are the two biggest culprits. Too much or too little refrigerant can cause your air conditioner to overwork. The same is true if the air flow across the inside coil is low. CheckMe!^TM focuses on these two problems.

Q. How does the CheckMe!^TM analysis detect improper refrigerant charge and air flow?
A. More technical information here.

Q. Who is using CheckMe!^TM?
A. CheckMe!^TM has been widely used throughout California's warmest regions:

• CheckMe!^TM was part of the 1998 PG&E, California Public Utilities Commission and California Board of Energy Efficiency funded effort to provide a means for homeowners in Fresno and Clovis to tune-up their home air conditioners.
• CheckMe!^TM is being used in the California Board of Energy Efficiency's 1999 programs by Southern California Edison.
