HOME / COMMERCIAL KITCHEN VENTILATION
Makeup Air Units · Balanced Intake

AIR OUT NEEDS AIR BACK IN. THAT’S THE WHOLE LAW.

Every CFM your hood exhausts has to come from somewhere. Without makeup air it comes under the doors, through the dining room, and out of your walk-in’s efficiency. We size, set and temper the air your kitchen breathes.

Scope of work

What we install

Tempered, interlocked, balanced — the three words that keep a kitchen comfortable.

SIZING

Matched to exhaust

MUA capacity engineered against total hood exhaust so the building sits at slight negative — not a wind tunnel, not a smokehouse.

TEMPERING

Heated & cooled intake

Raw 100° Houston air dumped on your line is a lawsuit from your cooks. Tempered units condition the air before it lands.

INTERLOCK

Runs when the hood runs

Wired so MUA and exhaust operate together — an inspector checkbox and an energy-bill saver.

BALANCE

Measured, not assumed

We read building pressure after install and document it. Doors close. Pilots stay lit.

How it runs

02

Questions we get

Straight answers

How do I know I have a makeup air problem?
Doors that whistle or won’t close, smoke rolling out of the hood face, HVAC that can’t keep up, pilots blowing out. All the same disease: more air leaving than arriving.
Does makeup air have to be heated or cooled?
Code in most jurisdictions requires tempering when it discharges near workers. Practically — untempered MUA in Texas summers makes the line unworkable. We’ll spec what your kitchen and city require.
Can you add MUA to an existing hood system?
Yes, that’s a common retrofit. We verify the exhaust totals, find roof or wall real estate for the unit, and interlock it with the existing hood controls.
