Hood Cleaning,
Done Right

Cherry Hill is one of the busiest dining markets in South Jersey. Between the Route 70 and Route 38 corridors, the town packs in national chains, independent kitchens, and everything in between, and almost none of it slows down for the season the way a shore-town kitchen does. That steady, year-round volume is good for business and hard on an exhaust system — grease builds up on a predictable schedule whether it is January or July.

A kitchen hood exists to do one thing: capture grease-laden air above the cooking line and carry it outside before it settles. Skip the cleaning and that grease does not disappear — it collects inside the hood, migrates into the ductwork, and coats the exhaust fan on the roof. Left long enough, it stops being a maintenance issue and becomes fuel sitting next to an open flame.

NFPA 96 is the national standard that sets minimum cleaning frequency for commercial kitchen exhaust systems, and Camden County kitchens answer to it the same as anywhere else in the state. A kitchen running solid-fuel cooking or a wok station is typically on a monthly cycle. A more typical Cherry Hill menu — burgers, fryers, a flat top — usually falls under the quarterly baseline. None of this is a suggestion: your fire marshal, your insurance carrier, and most health inspectors will all want signed proof that the cleaning happened on schedule.

There is also a cost to ignoring it that has nothing to do with fire risk. Grease-clogged baffle filters force the exhaust fan to work harder to move the same volume of air. That shows up as a hotter line, higher utility bills, and a fan motor under more strain than it should be. Cleaning the system as a whole — hood, baffles, duct, and fan — is what keeps airflow where it belongs.

Why a Full-System Cleaning Beats a Hood-Only Job

Most kitchens are better served booking the hood, duct, and exhaust fan together rather than piecemeal. Grease does not stop at the canopy — it travels the whole path, and a hood-only cleaning leaves the rest of that path dirty. If you are also due for a grease trap pump-out, we can combine both on the same after-hours visit so your kitchen only loses one night, not two.

Filter exchange runs on its own, tighter cycle for kitchens that generate grease faster than a quarterly hood cleaning can keep up with. Instead of scheduling a full degreasing appointment every time the baffles saturate, we swap in a clean set and take the dirty ones with us. It is a fast fix that keeps the system from falling behind between full cleanings.

Signs Your System Needs Attention Before the Inspector Shows Up

Waiting for a failed inspection to trigger a cleaning is a bad strategy in a market this competitive — a shut kitchen on a Friday night in Cherry Hill costs real revenue. There are warning signs worth acting on first.

Grease dripping or pooling at the edges of the hood is the clearest signal. If it is visible on the outside of the canopy or on equipment underneath, the interior is worse. Smoke that hangs over the line longer than it used to, without any change in cooking volume, usually points to a partially blocked duct or fan. On the roof, a dark ring on the membrane around the fan housing means the grease containment tray has already overflowed.

Inside the building, a sulfur smell rising from floor drains — worse on hot days — is a grease trap nearing capacity, not something a drain cleaner will fix. A grease trap pump-out is the only real solution once that odor shows up.

What a Real Cleaning Crew Actually Does

A proper hood cleaning is not a quick wipe with a rag — plenty of operators in this market have had that experience with a cut-rate crew and paid for it at the next inspection. Ours starts with a pre-clean inspection to gauge grease load and flag mechanical issues. We lay drop covers to protect the line, apply a commercial-grade hot degreaser, let it dwell, then scrub and pressure-rinse everything from the hood canopy down through the duct to the rooftop fan. Every bit of grease we remove leaves the property with us — none of it ends up in your drains or on your roof.

Every visit ends with a signed service report listing the technician, date, areas cleaned, and anything we found that needs follow-up. Keep it with your health permit and fire suppression records — it is exactly what a fire marshal asks to see at inspection.

When Not to Call Us

Cleaning cannot fix a system that was installed wrong in the first place — undersized ductwork, a fan that cannot keep up with the BTU load, makeup air that is badly out of balance. We will tell you exactly what we see during the inspection, but correcting a mechanical or installation problem is a job for an HVAC contractor, not a cleaning crew, and we will say so rather than pretend a degreasing will solve it.

We also do not work on residential range hoods. Our crew and equipment are built for commercial volume. A home kitchen or a very small café running a recirculating hood is not a good fit for us, and we would rather tell you that up front than take the job.

Cleaning requirements are governed by NFPA 96 and enforced locally by the NJ Division of Fire Safety. For grease trap requirements, refer to the EPA's FOG prevention guidance.
