Commercial Exhaust Fan Replacement in Mesa, AZ | Commercial Fan Replacement
Mesa Hood & Exhaust Co. handles commercial exhaust fan replacement in Mesa, AZ, and most of the job comes down to one measurement, the roof curb. A new fan has to match the old unit's CFM and static pressure, and its base has to sit on your curb without gaps. When it doesn't, our licensed technicians fit an adapter curb so rain stays out and the fan stays level.
Our team also confirms the replacement carries a UL 762 listing for grease service, wires the motor to your disconnect, and installs a hinge kit so the next cleaning crew can tilt the fan safely. Heavy belt-drive units on hotel and hospital roofs may need a lift or crane, and our crew plans that before install day.
After the last bolt goes in, the fan runs under load while amperage gets checked, and photos of the finished install go into your file. Mesa Fire and Medical Department inspectors and your insurer can read the paperwork without a phone call. Crews have been climbing Mesa roofs for 20 years, and service reaches Gilbert and Tempe as well.

Commercial kitchen exhaust fan replacement starts with matching the new fan to the airflow your hood was designed for, since an undersized fan leaves smoke behind and an oversized one strains your makeup air.
Our licensed technicians read the nameplate on the old unit, confirm CFM and static pressure, and set the new fan on your existing roof curb, using an adapter when the footprint differs. Hotel and hospital roofs often need a lift for the heavier wheels. The right match pulls smoke off the line without whistling.


Restaurant exhaust fan replacement makes sense once repair bills stack up or bearings keep failing after every fix.
Mesa Hood & Exhaust Co. installs UL 762 listed upblast fans, wires the new motor to your existing disconnect, and fits a hinge kit so future cleanings can tilt the fan safely. Fresh bearings and a balanced wheel spin with less vibration, which spares your roof and your ears.
Commercial ventilation fan replacement covers the fans beyond your main upblast, including inline exhaust, makeup air, and dish room fans that fail quietly until the kitchen heats up.
Our experts swap motors and blower wheels, match belt sizes, and confirm the dampers open fully. Cooks work in cooler air afterward, and nearby equipment stops absorbing steam it was never built for.


Type I exhaust fan replacement swaps out fans serving grease hoods, where the unit must carry a UL 762 listing for grease-laden vapor.
Our technicians install each fan with its grease containment box, fit the hinge kit, and check discharge clearance so vapor leaves upward instead of settling. Correct placement keeps grease off your roof membrane and gives your inspector a fan that looks the way the code expects.
Food truck exhaust fan replacement fits compact direct-drive upblast fans onto your truck roof, where space runs tight and power comes from a generator.
Our team works at your commissary or event lot, mounts the new fan on fresh sealant, and tests amperage against your generator's capacity. A sealed mount stops rain leaks, and a fan sized for the truck keeps smoke away from the service window.


After-hours exhaust fan replacement gets the old fan off your roof and the new one running between last close and first prep.
Mesa Hood & Exhaust Co. stages the replacement unit and hoisting gear before you close, disconnects power, sets the fan, and restarts it under load before dawn. You open on schedule with new airflow, and no crane sits over your building during service hours.
CFM, horsepower, voltage, and drive type come off the nameplate, and our technicians measure your curb before ordering anything.
Crews source a UL 762 listed upblast fan that matches airflow, plus an adapter curb or hinge kit if your roof needs one.
Step 3: Disconnect and Lift
Power gets locked out and tagged, then the old fan comes off the curb, by hand or with a lift when it's heavy.
The new fan goes onto fresh curb sealant, gets bolted level, and connects to your disconnect and grease containment box.
Amperage, rotation, and vibration get checked with the fan running, and you receive photos of the finished install.
The fan itself spans a wide range. Catalog listings for rooftop upblast exhausters start from about $477 for direct-drive units and from about $1,501 for heavy-duty belt-drive models, and those figures cover equipment only.
Meanwhile, labor, roof access, and electrical work sit on top of that. Rooftop installations on multi-story buildings often require crane rigging, which adds its own line item.
Costs | How it affects your quote |
|---|---|
Direct-drive fan equipment (catalog starting price) | About $477 and up |
Heavy-duty belt-drive fan equipment (catalog starting price) | About $1,501 and up |
Roof curb match | An adapter curb adds materials and labor |
Roof access and rigging | Lifts or cranes add cost on tall or heavy jobs |
Electrical work | New disconnects or wiring changes add labor |
Service timing | After-hours or rush installs may add to standard rates |
Our technicians measure your curb, read your nameplate, and inspect roof access before quoting, so your estimate covers the fan, the labor, and any rigging.
