All air conditioners and heat pumps require regular maintenance to perform at peak efficiency. Each central air conditioning unit should be inspected, cleaned and tuned by a professional at regular intervals.
The Technician Should
* Measure the refrigerant to see if it needs recharging. An undercharged unit
lowers the efficiency of the system.
* Measure the airflow over the air conditioner's cooling coils. Inadequate airflow
is a common problem and correcting airflow rates can increase efficiency 5 to
10 percent.
* Clean and inspect the motor, compressor, air handler, ducts, coils and air
filter.
