Your heating and cooling system equipment runs best when properly maintained.
One of the easiest ways to maintain your system is to change your filters on a regular basis.
Also having your HVAC system serviced on an annual basis will help ensure that your system is not costing your more than it should. Plus proper maintenance will help increase the life of the system itself.
And don’t forget to check to make sure that inside and outside coils are kept clean and free of debris.
Finally, if you have an older unit it might be time to upgrade your HVAC to a new Energy Star model and see how it might make paying bills more comfortable.
