Common Whole-House Ventilation System Service Questions

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.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

You can do some basic heat recovery ventilator maintenance yourself, including removing and cleaning the filters once a month and replacing them yourself every 6 to 12 months. You can also shut off and unplug the unit before cleaning debris out of the core unit. You can also clear clogs from the condensate drain and make sure that remains clean and functional. Beyond that, you should hire a professional HVAC technician to check and adjust belts, heat exchangers, and other internal components to keep it in good working condition.
