Common Whole-House Ventilation System Service Questions

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.

Costs depend on fan size, attic accessibility, labor, and whether additional ventilation adjustments are needed.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Clean fan blades periodically, check wiring for safety, and inspect attic ventilation to ensure efficiency.

It depends on which type of whole-house ventilation system you choose. Generally speaking, exhaust-only and supply-only ventilation systems will be the least expensive to install, while balanced ventilation and energy recovery systems tend to be pricier. For instance, a whole-house fan costs an average of $1,700, while an ERV system usually comes out to $2,000 or more.
