It is very important to remember to keep a clean filter in your Heating and Air Conditiong System. These will typically be located in the entry and hallway areas in newer homes. And in older homes it will be found inside of the furnace or air handler itself. Some may be washable filters that can be cleaned with a garden hose. Others will be disposable pleated filters that can usually be found at your local hardware store. We recommend signing up with filtersfast.com, they have a convenient auto order feature that will send them to your home bi-annually or whichever timeline you might choose. It is a good idea to check the filter every few months, and always remember to date the filter when replacing so there’s no question on when you were last there!
