Make-Up Air Unit Installation for a High-Power Range Hood in Blaine

Most homeowners don't think twice about make-up air - until they install a powerful range hood and start noticing negative pressure issues, backdrafting, or doors that are suddenly hard to open and close. If your range hood moves more than 400 CFM, you're pulling a serious amount of air out of your home. That air has to come from somewhere.

That's exactly what we were dealing with on this job in Blaine. The homeowner wanted the cooking power to match their ambitions - and that meant the ventilation system had to keep up. When you're exhausting that much air, building codes and basic physics both require a make-up air solution to replace what's being pushed out.

What we installed here is a make-up air unit that brings fresh outside air back into the home to compensate for what the range hood is exhausting. In colder climates - and Minnesota winters are no joke - that incoming air often needs to be heated before it enters the living space. A heated make-up air unit handles exactly that, so you're not blasting cold air into your kitchen every time you fire up the stove.

The ductwork routing on a job like this takes real planning. Getting the airflow balanced, making sure the unit is properly tied in, and ensuring everything is sealed and secure - it's not a simple swap. We handle the full install from unit placement to duct connections so the system works the way it's supposed to from day one.

If you're planning a kitchen upgrade with a high-output range hood, this is something worth thinking about early in the process. The make-up air requirement catches a lot of people off guard, and retrofitting it later is always more work than planning it in from the start.
