Why the Rooftop Exhaust Fan Gets Cleaned Too

The last part of a restaurant’s duct exhaust system usually sits where nobody in the kitchen looks: on the roof.

Every time the cookline runs, grease-laden air rises into the duct exhaust hood. The grease filters catch much of it, but some carries on through the plenum and the ductwork and reaches the rooftop exhaust fan, where it builds up on the fan and around its base. Cleaning only what can be seen from the kitchen leaves that end of the system untouched.

That’s why Allen’s Duct Systems treats the rooftop fan as part of the same exhaust system that starts over the cookline. On the roof, the fan is tilted back so the grease can be cleaned from the fan and the duct opening beneath it, then rinsed off before the fan is closed up again. Removing accessible grease buildup helps support the ongoing fire-safety maintenance of a commercial kitchen exhaust system.

To book a cleaning or get a free estimate, call Mrs. Allen at (917) 930-5887.

Where Grease Filters Go During a Duct Exhaust Cleaning

Once the cookline is covered, the grease filters are the next thing to come out of the duct exhaust hood.

At Allen’s Duct Systems, each filter is cleaned on both sides, and the tracks, rails and frames it sits in are cleaned while it’s out. With the filter bank open, the accessible plenum behind it gets cleaned too. Before the filters go back in, each one is inspected.

Some filters don’t pass that look. A filter that is damaged, warped, missing or the wrong size is a job for grease filter replacement, a separate service: the filter bank is measured, replacements are matched in size, quantity and orientation, and the new filters are installed and checked for fit.

Questions about your filters? Call Mrs. Allen at (917) 930-5887.

Who to Call About an FDNY Duct Exhaust Violation

A violation on the duct exhaust system brings up two questions right away for many restaurant owners: what needs to be cleaned, and when can the work get done.

At Allen’s Duct Systems, those questions go straight to Mrs. Allen. Mr. and Mrs. Allen founded the company in 1998, and it is still a family business, so the person on the phone is part of the family that runs it.

Violation removal is the cleaning work performed to clear an FDNY violation on a restaurant’s duct exhaust system. It follows the same process we use on every job, from protecting the cookline before any work starts to the final review and service sticker. Removing accessible grease buildup helps support the ongoing fire-safety maintenance of a commercial kitchen exhaust system.

Allen’s Duct Systems is an FDNY Approved Company, #065, with free estimates for restaurant kitchens across the five boroughs. Call Mrs. Allen at (917) 930-5887.

Keeping Duct Exhaust Cleaning on a Regular Schedule

Keeping Duct Exhaust Cleaning on a Regular Schedule

A cleaning schedule takes one question off a busy manager’s list: when was the duct exhaust system last cleaned?

Every day of cooking sends grease into the duct exhaust hood, onto the grease filters and into the connected ductwork. Scheduled cleaning, also called routine or regular cleaning, puts each visit on the calendar in advance, so it is planned rather than squeezed in at the last minute.

Removing accessible grease buildup helps support the ongoing fire-safety maintenance of a commercial kitchen exhaust system, and a regular schedule keeps that cleaning from being put off.

What Emergency Duct Exhaust Service Covers

Most duct exhaust cleaning is booked ahead, on a schedule that works around a kitchen’s hours. Some calls can’t be planned.

Emergency service is part of Allen’s 24/7 availability, and that includes weekends. When a restaurant calls with an urgent duct exhaust problem, the work covers the same connected system as any full cleaning: the duct exhaust hood, the grease filters and the tracks that hold them, the accessible plenum behind the filters, accessible sections of the ductwork, and the rooftop exhaust fan.

The cookline is protected before anything else is touched. Filters come out, degreaser goes on, heavy grease is removed, and accessible areas are washed with hot water before everything is reassembled, polished and reviewed. Damaged or warped filters found along the way can be replaced, since grease filter replacement is its own service at Allen’s.

Allen’s Duct Systems is family owned, FDNY Approved Company #065, and licensed & insured, serving restaurant kitchens across New York City and Westchester County. Restaurants speak directly with Mrs. Allen at (917) 930-5887.

What Shows Up Once the Grease Filters Are Pulled

From the kitchen floor, a row of grease filters can look like a solid wall of stainless steel. Once those filters come out, the space behind them comes into view: the tracks and rails that hold each filter, and the accessible plenum where the duct begins.

That is why grease filter cleaning at Allen’s is done with the filters out. The cookline is protected first, the filters are removed, and their front, rear and baffle surfaces are cleaned. Then the tracks, rails and frames are cleaned, along with the accessible plenum behind them, before every filter is inspected and put back in place.

Pulling the filters can also show what a quick look from below misses: heavy buildup around the filter tracks, or a filter that is warped, damaged or the wrong size. Filters like that are replaced rather than washed again and again, and grease filter replacement is its own service at Allen’s.

Duct Exhaust Cleaning for Quick-Service Kitchens

Quick-service kitchens cook fast and cook a lot, with fryers, griddles and flat-tops running through the day.

That steady cooking sends grease into the grease filters, and from there into the plenum and the connected ductwork. High-volume cooking loads the filters faster, and buildup around the filter tracks is common in busy kitchens. Allen’s Duct Systems cleans the grease filters and their tracks, the accessible plenum and ductwork, and the rooftop exhaust fan, following the whole connected exhaust path. Removing accessible grease buildup helps support the ongoing fire-safety maintenance of a commercial kitchen exhaust system.

Allen’s offers scheduled cleaning, and emergency service is available 24/7. A free estimate starts with a call to Mrs. Allen at (917) 930-5887.

Why Grease Filter Fit Matters

Grease filters are made to sit snug in a row along the bottom of the duct exhaust hood, each one seated in its track.

When a filter is missing, warped, damaged or the wrong size, the row ends up with a gap or a loose fit, and washing that filter again won’t fix it. That’s when Allen’s Duct Systems replaces it. We review the filters, confirm which ones need replacing, measure the filter bank, and match the new filters’ size, quantity and orientation. Then we install them and check that each one fits, lines up and sits steady.

Replacement is its own service, separate from grease filter cleaning, so filters that are still in good shape are simply cleaned. You can read more about grease filter replacement here: https://allensductcleaning.com/services/restaurant-grease-filter-replacement/

What Full-System Kitchen Exhaust Cleaning Includes

Full-system kitchen exhaust cleaning follows the grease along the same path the air takes out of the kitchen.

It starts with protecting the cookline. Then the grease filters come out, and the duct exhaust hood and canopy, the accessible plenum behind the filters and the connected duct sections that can be reached are all cleaned. The rooftop exhaust fan at the end of the path is included too. Last comes reassembly, finishing and a final review, and a service sticker is placed.
