Reduce your cooling bills

All air conditioning systems, large or small, need good air flow across the condenser coil. Its purpose is to transfer heat from the refrigerant used in the system. Efficiency and performance drop rapidly as air flow decreases. 

The condenser fan moves air across the coil to increase the transfer of heat. Pressure inside the coil can exceed 400 psi., during warm weather conditions. The cleaner it is kept, the better it transfers heat. Routine maintenance and servicing will help keep it operating efficiently. After years of use it may be necessary to put special chemicals on to clean condensers.

Obstructing the flow of air will not only reduce efficiency but can lead to compressor failure. Keep debris and objects away from condenser coil and fan to allow maximum air flow. Some condenser fan motors have sealed bearings, others need lubrication. Damage to the fan can occur if serviced or removed improperly. Have a qualified serviceman handle the work if needed.
