Improving Air Conditioning


It's that time of year when the Dog Days of Summer are really making your air conditioning system work longer and harder than any other time of year, and if you want to get full service life out or your unit and minimize repairs over the life of the unit, it is important to regularly service and clean the unit.

According to the U.S. Governments Energy Information Administration, (, From 1978 to 1997, the total amount of electricity used in the residential sector increased from 2.47 quadrillion Btu in 1978 to 3.54 quadrillion Btu. Over the same period, electricity used for residential air-conditioning rose from 0.31 quadrillion Btu to 0.42 quadrillion Btu. Among the reasons air-conditioning electricity use did not rise more is the increasing efficiency of air-conditioning equipment.

Short of replacing your existing condensing unit with a new higer SEER model, (A standard measure of air-conditioning equipment efficiency is the Seasonal Energy Efficiency Ratio (SEER). For a given piece of equipment, the higher the SEER, the greater its efficiency, and the lower its electricity consumption) Keeping your system serviced and cleaned is the most important part of improving efficiency.

Your exterior condensing unit pulls air in from the sides of the unit through the coils, cooling hot freon, and exhausting the heated air out the top of the unit. Unfortunately, it also pulls in dirt, grass, pollen, etc., which can clogg the coils reducing the flow of air and affecting efficiency. (See the Photo Above).

Keeping shrubs from close proximity to the unit is also advised, as this can significantly restrict air flow through the coils.

In addition to the above, you should also:

  • Check and change filters when dirty
  • Have freon levels checked and your interior evaporateor coil cleaned & serviced by a professional HVAC contractor prior to cooling season.
  • Improve attic ventilation and insulation if ducting is routed through the attic to lower heat load to ducting and ceilings.

Your air conditioning system is designed to provide you with a long full service life. Maintain your system regularly to insure you get the most out of your system.
