You should remove and clean your HRV filters about once a month, as debris will build up quickly, especially on the fresh air side of the ductwork. Even with routine cleaning, you should plan to replace the filters at least once a year or more often if you find that they’re getting dirty quickly during operation.

Yes, duct sealing is considered an essential task for most homes. Even small, seemingly minor leaks in your ductwork can lead to significant energy waste, reduced HVAC system efficiency, and decreased indoor comfort. For older homes, sealing is especially crucial as ducts are likely to have developed gaps and leaks over time, impacting both energy bills and air quality. However, even in newer homes, proactive duct sealing can prevent future issues and optimize your system's performance. A comprehensive approach that seals all leaks is key to maximizing energy efficiency and maintaining a comfortable home environment.

To optimize airflow and energy efficiency, regularly clean vents and replace air filters, schedule periodic professional duct inspections, and seal any visible leaks. Proper maintenance prolongs ductwork longevity and performance.

If you have a fresh air intake as part of your HVAC system, the interior vents should be near your furnace or other gas appliances inside your home. From the outside of your property, your HVAC fresh air intake location is usually near the ground (although it may also be higher up, like on the roof or attic).
