Essex · Air handling unit cleaning
Air handling unit cleaning in Mowden, Essex
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Mowden: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Intake sections clogged with outdoor debris
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
AHU cleaning in Mowden
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. If you have stale or musty smells from the ventilation and air handling units never cleaned inside, we can help, from filter sections, dampers and louvres and internal panels onwards.
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.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

When to call us in Mowden
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Look out for any of the following:
- Dirty fans and fan housings
- Dirty coils holding back the airflow
- Condensate trays that will not empty
- Rooms that smell stuffy when the system runs
Healthcare ventilation, from large hospitals like Priory Hospital (about 3.9 miles west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- When they can work, and whether that’s outside your opening hours
- What’s included in the scope, part by part
- If the quote is a fixed price or an estimate
- How areas they cannot reach will be recorded
Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Leave it or put it right?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Rural sites cannot always move to another kitchen or room when something fails.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Mowden, let us know and we’ll plan around it.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
- Clear loose items from the work area
How to get a quote
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or email photos.

Questions from Mowden
Do you work overnight in Mowden?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you work in villages like Mowden?
Yes. Mowden is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How much does AHU cleaning cost in Mowden?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.
