AHU cleaning for kitchens and businesses in Gilston
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Common call-outs are for leaves and litter drawn into the unit and drain trays holding standing water, across drain trays, heating and cooling coils and internal panels.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
A written report with photos follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Gilston: your questions answered
Can ventilation in schools around Gilston be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Gilston. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we will fit the work in.
Do you work overnight in Gilston?
Yes, nights and weekends are routine for us. The work in Gilston can fit around your hours. Your opening times are the first thing we ask for.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

Gilston buildings and their air
Food Standards Agency records list about 9 schools, colleges and universities, about 12 hospitals, care homes and childcare premises and about 3 hotels and B&Bs registered as food businesses in Gilston and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Gilston, about 22 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. About 1.4 miles south-west of Gilston is Princess Alexandra Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Hospitals such as Princess Alexandra Hospital (about 1.4 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Gilston are no different. For schools like St Alban's Catholic Academy, the holidays are the usual time to inspect and clean ventilation. If you manage shops or offices close to Harlow Town station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Keeping the system healthy
To keep the system working properly between visits:
- Do not store bins or materials near the intake
- File each AHU report in the maintenance log
- Note any water around the unit or leaks below it
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Gilston run smoothly.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Mention any parking or loading restrictions
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
