Commercial Hood Exhaust System Repair in Mesa, AZ | Exhaust System Repair
Mesa Hood & Exhaust Co. performs commercial hood exhaust system repair in Mesa, AZ for restaurants, hotels, school cafeterias, and food trucks. There are three things that define our crews. They bring 20 years on Mesa rooftops and kitchen lines, they clean and repair in one visit so the crew that degreases your hood also fixes it, and they leave photo records of every repair for inspectors and insurers.
Grease wears out hoods in predictable places. Canopy seams crack, duct gaskets dry out, and fan mounts work loose. Mesa summers speed that up, since 105-degree roofs bake sealant until it splits.
Our licensed technicians trace each symptom to its source, fix it, and test airflow before they leave. Repairs range from resealing a roof penetration to welding a duct seam. Mesa Fire and Medical Department inspectors see a system that meets NFPA 96 and the International Fire Code, and you see fewer surprises on inspection day. Our crews also reach Gilbert, Tempe, and Chandler.

Our licensed technicians trace each symptom to its source before any tool comes out. Smoke then stays on the line, and grease stops dripping into ceiling tiles.


Restaurant hood exhaust repair starts when your hood drips grease onto the cooktop or loses its pull during dinner service. Our crew checks canopy welds, baffle tracks, and the drip trough, then repairs each defect with stainless patches and fresh sealant. Your hood captures grease again, and your line stays open.
Type I hood exhaust repair covers the UL 710 listed canopies above fryers, griddles, and charbroilers. Our technicians repair cracked welds, bent baffle tracks, and leaking grease cups.


Cooking line exhaust repair targets trouble you see at the cooktop. Smoke rolls past the canopy edge, grease drips from a filter track, or one hood pulls weaker than its neighbor. Mesa Hood & Exhaust Co. tests airflow hood by hood, finds the leak, blockage, or loose damper behind the problem, and fixes it. Your cooks work in cleaner air, and every appliance on the line gets the same pull.
Food truck exhaust system repair happens at your commissary or event lot, since nobody wants a truck parked in a shop for a week. Our crew reseals roof penetrations, tightens fan mounts that road vibration loosens, and repairs cracked stack welds on compact hoods.
Maricopa County Environmental Services inspectors look closely at mobile units, and sound exhaust hardware keeps fumes away from the service window.


Emergency exhaust system repair covers failures that need attention now, like smoke spilling into the dining room, grease pouring from a duct seam, or a fan that quit mid-service.
Our technicians stop the leak or restore airflow first, then document the damage for your insurer and inspector. Temporary fixes get labeled as temporary. A permanent repair plan follows in writing, so you know what broke, what got fixed, and what remains.

Our technicians check seams, gaskets, dampers, and fan mounts, and run a smoke test to spot leaks.
Step 3: Protect Your Kitchen
Plastic covers equipment, power gets locked out at the fan, and fire blankets guard the cooking line during any welding.
Crews weld liquid-tight seams, swap gaskets, reseal roof penetrations, and realign dampers using stainless steel and high-temperature sealant.
Airflow gets tested with the fan running, and photos of each repair go into your report.

HVAC trades charge $75 to $150 per hour for complex work, according to HomeGuide, which gives you a fair reference point for exhaust repairs.
