Your hood fan pulls smoke and heat out. Your make-up air unit replaces that air. When one fails, both feel it.

Frequently Asked Questions
Why are my restaurant's doors hard to open?
Usually the kitchen exhaust is pulling out more air than is coming back in, often because the make-up air unit isn't running or isn't bringing in enough air. We'll check both units and the controls that link them.
Why is freezing air coming into my kitchen in winter?
The make-up air unit is most likely running without heating the air. Common causes are an igniter, flame sensor, gas valve or control problem. Call us and we'll get it heating again.
My hood fan is squealing. Is that urgent?
A squeal often means a slipping or worn belt, or failing bearings. It's best dealt with soon, before the belt breaks or the motor fails mid-service.
Do you clean grease out of hoods and ducts?
Grease cleaning of hoods and ducts is a separate specialty from fan and make-up air repair. Ask us if you're not sure who to call and we'll point you in the right direction.
Can you come out during or after service hours?
Yes. We're open 24 hours, 7 days a week, so we can work around your kitchen's schedule.
