When was the last time you changed your air conditioner’s air filter?  The average home A/C air filter should be replaced once a month.  Doing so not only provides your home with fresh, clean air, but also plays a very important role in keeping your A/C system working properly.  A dirty filter can drastically reduce your system’s lifespan, cause damage requiring repairs, and have a big impact on energy efficiency.   According to the U.S. Department of Energy, making sure to have clean filters in your home can save you around 5-15% on your energy bill.  If you have any questions about air filters or other HVAC related questions feel free to contact a Gembecki Service expert today and be sure to ask about our maintenance program.
