older heating + cooling equipment

As much as half of the energy used in your home goes to heating and cooling, so it’s an important piece of your home energy efficiency puzzle.


What to Do

Have your heating and cooling systems serviced one a year.  Like changing your oil, this routine maintenance will keep the equipment running efficiently and your technician can spot a small issue before it becomes a big repair.  A combustion efficiency test, static pressure test and other diagnostic tests should be included.

Change your air filter according to package directions even if the filter doesn’t look dirty.  The filter keeps particles (some visible and some not) from getting into the motor.  A dirty filter will reduce airflow which causes the system to run less efficiently and can lead to equipment damage.  Don’t switch between flat and pleated filters.  Ask your technician to check that your system is set properly for the filter you want to use regularly.
