This is the single most important thing that needs to be done to keep your system clean and operating efficiently. If you have a standard furnace filter, we recommend replacing it monthly even if the old one still looks clean. High efficiency filtering systems, air cleaners, and ERV, may require different schedules. Pets, environment, and number of household members can all affect how often your filter needs to be replaced.

Most people don't realize their furnace and air conditioner run more and start and stop more than their automobile. Routine service is very important for energy efficiency and longevity of your equipment. Equipment that is not regularly serviced tends to need more repairs. We recommend having your system professionally cleaned and serviced a minimum of once per year.
