Every summer, we deliver tips to you on how to keep your energy bills low. From now until September, your air conditioner is going to run an average 18 hours a day. The costs add up quickly so we’ve compiled a list of simple things you can do to keep your energy bills at a minimum:

  • Rinse your outdoor condenser coil.
  • Don’t run your air conditioner when doing yard work. Cutting grass and weed eating produce dust that gets sucked into your air conditioner and can clog the unit. Did you know that just 1/32” of dust can lower the SEER rating on your air conditioner?
  • If possible move your clothes dryer vent away from your air conditioner. If it is near the air conditioner, make sure you don’t run your air while using your dryer.
  • Change your filters inside regularly.

Another very important factor is the type of filter you are using. Your typical 3M - 1” filters restrict airflow and are probably the number one reason for decreased efficiency.

A properly designed duct system operates at .5 static pressure with .7 being the highest permissible. The 1” filter doubles your static pressure (adding .5 to it) and lowers the air conditioner’s effectiveness. The CFM rate, (cubic feet per minute) of airflow on a 4 ton blower is cut in half when using a 1” inch pleated filter.

Alternately, using a 4” inch pleated filter will only increase your static pressure by .1 as opposed to .5. The high efficiency 4” pleated filter is much thicker and has much more surface area. The filter cloth does a much better job at improving indoor air quality and lasts far longer than the 1”.

Having an energy audit done by a qualified professional is the best way to analyze your air conditioning system and maximize your efficiency. We come out to your home to give your system a close inspection and at the very least, give you useful information on how to minimize your energy costs. Call us today for a free energy audit.
