Air Duct Cleaning questions, answered by experts

If you have a forced-air heating system, it’s important to have it professionally inspected at least once per year. During one of these visits, your contractor will look at all of the components of your HVAC system, including your furnace or heat pump, air conditioner, and ducts. On average, an HVAC inspection costs $300. It’s also important to perform basic maintenance between inspections, such as changing your filters and cleaning dust from around your vents.

While having a return vent in every room is unnecessary, it’s becoming more common in modern homes. You should ensure a balanced distribution of these vents throughout your home. This ensures that air circulates effectively, preventing hot or cold spots.

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.

A floor return vent needs a clearance of between 6 and 12 inches in front of it. You should not place large furniture, such as shelves, drapes, or couches, directly in front of a return air vent.

Smoke damage will not go away on its own, but with professional remediation and restoration, you can return your home to its original condition after a fire. Trained smoke restoration professionals can eliminate smoke damage, which can affect areas of your home that are hard to see or access, and restore or replace smoke-damaged materials.
