SIGNS YOUR COMMERCIAL KITCHEN HOOD SYSTEM NEEDS REPAIR
HOT & SMOKY KITCHEN
Smoke lingers, the line is uncomfortable, and the hood isn't pulling like it used to. Usually a failing motor, control, or clogged PCU.
FAILED INSPECTION
A fire or health inspector flagged your system. We document the fix and keep you compliant with NFPA 96 and local code.
ODOR COMPLAINTS
Neighbors or customers smelling your exhaust? Spent carbon or permanganate media and out-of-spec controls are the usual culprits.
WASH CYCLE WON'T RUN
Hood wash not cycling, pumps dry, or drains clogged? Wrong detergent and aging controls quietly kill performance.

FREQUENTLY ASKED QUESTIONS
COMMERCIAL KITCHEN HOOD SERVICE, ANSWERED
HOW OFTEN SHOULD A COMMERCIAL KITCHEN EXHAUST SYSTEM BE SERVICED?
Most manufacturers require pollution control units, electrostatic precipitators, and hood wash systems to be inspected and serviced on a set schedule, often monthly or quarterly, depending on your cooking volume to maintain warranty coverage, efficiency, and NFPA 96 compliance. Nelbud builds a service interval around your specific equipment, cooking load, and local code requirements.
WHAT IS A POLLUTION CONTROL UNIT (PCU)?
A pollution control unit cleans grease, smoke, and odor out of your kitchen exhaust before it leaves the building, typically using electrostatic precipitator (ESP) cells, filtration, UV light, or carbon media. Without regular cleaning and calibration, efficiency drops, odor complaints rise, and the unit can fail inspection or stop pulling smoke from the kitchen.
WHAT ARE THE SIGNS MY HOOD SYSTEM NEEDS REPAIR?
Watch for a hot or smoky kitchen, smoke or odor escaping the hood, visible plume or grease on the roof, neighbor odor complaints, an indicator light or alarm on the control panel, a hood wash cycle that no longer runs, or a failed fire or health inspection. Any one of these means the system is no longer performing as designed and should be serviced.
WHICH HOOD AND VENTILATION BRANDS DOES NELBUD SERVICE?
Nelbud is a trained, certified representative for all major brands; including Halton, Gaylord, VentMaster, Trion, Accurex, CaptiveAire, Carroll, Caddy Corporation, and Avtec Industries, across electrostatic precipitation, UV filtration, hood wash, and carbon/odor-control technologies. No matter the technology you installed, we can service it.
WHY DOES MY PRE-ENGINEERED HOOD WASH SYSTEM NEED A SPECIFIC DETERGENT?
Pre-engineered hood wash systems are designed to dispense one specific manufacturer-approved detergent. Using the wrong product can sharply reduce grease-removal efficiency or cause the system to damage itself. Nelbud uses only manufacturer-approved detergents and can replace obsolete controls with U.L.-listed alternatives so the system performs exactly as it did when installed.
DO YOU PROVIDE DOCUMENTATION FOR COMPLIANCE AND INSURANCE?
Yes. Every Nelbud service includes before & after photos, compliance documentation, and reporting, all accessible through your customer portal. It's backed by our ISO 9001:2015 accredited Quality Management System, so you have a defensible record for inspectors and insurers.

PRE-ENGINEERED HOOD WATER WASH SYSTEMS REPAIR & MAINTENANCE
KEEP YOUR HOOD WASH PERFORMING AND AVOID A COSTLY RIP-AND-REPLACE
Pre-engineered hood wash systems are built for efficient grease removal, but they're only "automatic," never "maintenance-free." The wrong detergent can cut efficiency to near zero or cause the system to damage itself. Our technicians:
- Inspect & maintain detergent pumps, timers & wash cycles
- Use only manufacturer-approved detergents
- Replace obsolete controls with U.L.-listed alternatives
- Restore proper operation as originally installed
- Clear clogged or blocked drains
- Prevent costly removal of a hood system that would otherwise need full replacement
