“Does your HRV need to run all the time?” 🤔
Not necessarily — but it should be running regularly.
An HRV is designed to constantly bring in fresh air and push out stale air. That’s what keeps humidity, odors, and air quality in check — especially in tighter, well-insulated homes.
✔️ Continuous low-speed = ideal for most homes
✔️ Boost mode = when cooking, showering, or high humidity
✔️ Off = not recommended for long periods
Turning it off completely can lead to stale air, excess moisture, and even mold issues over time.
Think of it less like a switch… and more like a system your home relies on every day.
