You may have heard suggestions to have the air ducts in your home cleaned, either from advice on a website (you’re reading one of these now) or from a sales person offering to take on the job for a surprising small amount of money (uh, we’ll get into this later).
Yes, your home’s ducts do need regular cleaning. The big question is how often do you need this duct cleaning?
Duct Cleaning Frequency
You’ll hear different answers for this, but from our 30 years of experience we believe duct cleaning in a house should be done every 5 to 10 years. This is provided the HVAC system has proper regular filter maintenance; we recommend you change the HVAC filter every 1 to 3 months, depending on the type of filter. (This is a topic for a different post. You can always ask us during regular maintenance for our expert advice.)
