In fact, Energy.gov says changing your filters (as often as every 30 days, depending on your filter type) is your most important maintenance task for preserving your system’s efficiency. That’s because clogged, dirty filters block the normal airflow. When airflow is obstructed, air that bypasses the filter could carry dirt straight into the evaporator coil and cause damage. That means the simple step of a filter change can protect your equipment’s life.
It can also save on energy. Replacing a dirty filter with a clean one can lower your heating and air conditioner’s energy use by 5 to 15 percent. And if that’s not reason enough to take care of this task – if your filter becomes too dirty, it can affect the quality of your indoor air. Remember, a dirty air filter can reduce air flow up to 60%.
How and when you make the change depends on the type of filter your system uses. While some are reusable, others must be replaced. You’ll want to clean or replace filters more often if your air conditioner is in constant use or if you have furry pets in the home.
Also, don’t forget that your furnace and air conditioning system should get a professional tune-up to get ready for the upcoming season. Along with improving the performance of your system, technicians are also able to see problems that may be occurring and often make a simple fix before they grow into a larger repair.
If you have any questions or concerns about maintenance on your system, or if it’s time for your regular HVAC tune-up, just let us know.
