Fan Replacement at a Glance

The rooftop exhaust fan is the motor-driven fan at the top of your duct. It does all the pulling: without it, smoke, heat and grease stay in the kitchen.

What we replace
Worn-out kitchen exhaust fans and fan motors on the roof.
When to call
The hood isn’t pulling, the fan won’t start, or it squeals, grinds or shakes.
How fast
We work 24/7. Call 720-808-3020 any time and tell us what the fan is doing.
While we’re up there
We can clean the duct and the new fan’s curb in the same visit, so the new fan starts clean.

Signs the Fan or Motor Is Failing

  • Smoke rolls out of the hood instead of going up
  • The fan won’t start, or stops and starts
  • Squealing, grinding or rattling from the roof
  • The fan shakes or wobbles on its curb
  • The kitchen is hotter and smokier than usual
  • The motor smells hot or trips the breaker

A hood with no working fan can’t do its job, and most kitchens shouldn’t cook under it. Call us before the next service.

Grease in the fan makes it heavy and out of balance. We clean it at every hood cleaning.

Fan Questions

Why do kitchen exhaust fans wear out?

Grease. A rooftop exhaust fan runs hot, greasy air through it every day you cook. Grease builds up on the wheel and throws it out of balance, which wears the bearings and the motor. Regular hood cleaning includes cleaning the fan, which helps it last longer.

Can I keep cooking if the exhaust fan stops?

You shouldn’t. Without the fan, smoke, heat and grease stay in the kitchen and the hood can’t do its job. Call A-1 at 720-808-3020. We work 24/7.
