Commercial Hood Repair
For kitchens dealing with airflow problems, loud equipment, or system failure
A commercial hood system works under constant pressure. Day after day it pulls heat, grease, smoke, and combustion gases away from your cooking line. When it stops performing properly, the effects show up fast: rising temperatures, smoke hanging in the kitchen, staff working in uncomfortable conditions, and health inspectors flagging problems during routine visits.
We repair commercial hood systems for restaurants, cafeterias, hotels, ghost kitchens, and any other commercial cooking environment. Our technicians locate the root cause of the problem, complete the repair correctly, and verify the system is performing to specification before leaving the job.
WHY IT MATTERS
A Failing Hood System Affects More Than Comfort
Most kitchen operators notice the obvious signs first: a fan that sounds different than it used to, smoke that lingers near the line, or a unit that cycles on and off unpredictably. What is harder to see is the damage that builds up over time when these issues go unresolved.
Grease that is not captured properly accumulates inside ductwork. Heat that is not removed efficiently puts pressure on refrigeration and HVAC equipment. Makeup air imbalances make doors hard to open and create drafts that disrupt service. Fire suppression systems lose effectiveness when the hood they are mounted in is not functioning correctly.
Ignoring early warning signs does not make them go away. It converts a repair call into a much larger problem.
SIGNS OF A PROBLEM
When to Call for Hood Repair
Contact us if your kitchen is experiencing any of the following:
Smoke or cooking odors are escaping from the cooking line into the dining area or back-of-house
The exhaust fan is louder than normal, vibrating, or making grinding noises
Airflow feels weaker than it should be at the hood face
The makeup air unit is not keeping up with exhaust, creating negative pressure at entry points
Grease is accumulating on surfaces near the hood faster than usual
The system is tripping breakers, shutting off unexpectedly, or failing to start
Your last health inspection cited hood performance or ventilation issues
Staff are complaining about heat or poor air quality on the line
These problems do not resolve on their own. Early repair prevents them from escalating into full system failure during a service period.
OUR SERVICES
What We Repair
Contact us if your kitchen is experiencing any of the following:
Exhaust Fan Repair
Motor failure, blade damage, and bearing wear reduce airflow and increase noise. We diagnose and restore full fan performance.
Makeup Air Unit Repair
An unbalanced makeup air unit creates pressure problems that affect the entire kitchen. We recalibrate or repair the unit to restore proper air balance.
Grease Filter Maintenance & Replacement
Clogged or damaged filters restrict airflow and increase fire risk. We clean, align, or replace filters to keep the system operating safely.
Baffle & Duct Cleaning
Grease accumulation inside ducts reduces airflow and creates fire hazards. We clean internal components thoroughly to restore capacity and safety.
Belt & Pulley Replacement
Worn belts cause slipping, noise, and reduced fan speed. We replace belts and pulleys to bring the motor back to rated performance.
Control Board & Wiring Repair
Faulty controls cause inconsistent fan speeds or complete shutdowns. We trace electrical faults and restore proper system control.
Fire Suppression System Inspection
We verify that suppression components are intact and properly connected as part of hood system repairs.
Hood System Balancing
After any repair, we test and balance the entire system to confirm proper airflow, pressure, and capture velocity across the cooking line.
OUR PROCESS
How We Diagnose and Repair Commercial Hoods
Every repair call follows the same structured process. This keeps the work organized, reduces the chance of missed faults, and gives you a clear picture of what was done.
1
Initial Assessment
We start by reviewing the system setup, getting your description of the problem, and noting anything that has changed recently, including menu adjustments, cooking volume increases, or previous repair work. This context helps us prioritize where to look first.
2
Full System Inspection
We inspect the exhaust fan, motor, belts, bearings, filters, baffles, ductwork, makeup air unit, controls, and electrical connections. We do not limit inspection to the component that appears to be failing. Secondary faults frequently accompany the main problem.
3
Airflow Measurement
We use calibrated instruments to measure face velocity and capture velocity at the hood. These readings tell us whether the system is moving the volume of air it was designed to handle and where losses are occurring.
4
Repair and Component Replacement
We carry common replacement parts on our service vehicles. For most repairs, we can complete the work in a single visit. If specialized components are needed, we will give you a clear timeline and keep downtime to a minimum.
5
Post-Repair Verification
After completing the repair, we retest airflow and system performance. We will not sign off on the job until the measurements confirm the system is operating correctly. You receive a summary of what was found, what was repaired, and the results of the post-repair tests.
WHY CHOOSE US
The CRS Hoods Difference
We Find the Real Problem
We diagnose before we quote. Many repair calls come in after a kitchen has already paid for parts that did not fix the issue. We trace every fault to its source before recommending a repair path.
We Work Around Your Schedule
A hood repair does not need to shut down your operation. We schedule around your prep times, off-peak hours, or closures to minimize disruption. If emergency service is needed, we respond quickly.
We Carry the Parts That Matter
Our technicians stock the components that fail most often in commercial hood systems. That means fewer return visits and faster resolution on the most common repair types.
We Leave You With Documentation
Every completed repair comes with a written record. You have clear documentation of what was inspected, what was repaired, what parts were used, and what the post-repair airflow readings showed. That record matters for health inspections, insurance claims, and warranty purposes.
We Understand Code Requirements
Commercial kitchen ventilation is covered by fire codes, health codes, and local mechanical codes. Our technicians understand what inspectors look for and perform repairs that meet those standards.
