A dirty air conditioner does not run as “smoothly” as a clean one. This means it has to work harder to give you the same results, costing you extra on your electric bill. Some air conditioning problems can DOUBLE the operating cost without increasing comfort. Just 1/100th of an inch of dirt or film on an evaporator coil can reduce its efficiency by 5%.


Systems that are properly maintained live longer than ones that are set aside and forgotten about. Up to 80% of all air conditioning compressor failures could be eliminated if the problems that lead to failure were corrected in a timely manner.


Air conditioners can run at over 250 volts. Any exposed components could pose a fire and/or shock hazard.

Refrigerant should never have to be replaced, if it must be added every year, there is an expensive leak that should be repaired. Make sure all refrigerant is properly pumped out by your certified Harker service technician and disposed of in an environmentally safe manner.
