Air handling unit cleaning in Horsleycross Street, Essex
Air handling unit cleaning for commercial sites in Horsleycross Street and across Essex. CHAS, SafeContractor and ISO 9001, and fully insured.
- Units needing a clean before a new tenant or handover
- Dirty fans and fan housings
- Dirty coils holding back the airflow
Between visits
Think of this as the after-treatment advice, in brief:
- Clear leaves and litter away from the intake
- Stick to the filter change plan
- Make sure the unit’s access doors open easily
- Diary the inspection date recommended in the report
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
About our AHU cleaning in Horsleycross Street
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. The work covers drain trays, internal panels and heating and cooling coils, and the jobs we see most are odours coming through the supply air and dirty filters cutting the airflow.
Somewhere as small as Horsleycross Street, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

About 58 miles out from central London, Horsleycross Street is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.

How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. The timing of a visit to Horsleycross Street is set by you, and the travel is our side of the planning.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Common problems we fix in Horsleycross Street
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Any of these means the system needs a check-up:
- Stale or musty smells from the ventilation
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Air handling units due a clean after building work
For buildings in and around Horsleycross Street, TR19® Air cleaning starts with an inspection.
Before booking anyone
- What hours they’ll be on site
- Whether VAT is included
- If the quote is a fixed price or an estimate
- What insurance they carry
For landlords and multi-site operators
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Systems in rural buildings are often out of sight and out of mind.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Horsleycross Street: your questions answered
Can the work in Horsleycross Street be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Horsleycross Street needn’t be disturbed. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you work in villages like Horsleycross Street?
Yes, we work in villages as well as towns, and Horsleycross Street is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
How long will the unit be out of action?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, so give us a ring on 0345 646 2711 or use the quote form to talk it through.
What affects the quote in Horsleycross Street
The survey tells us what the work involves. The main factors are:
- Site rules, permits and inductions
- Parking and loading at the site
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
Asking for a quote
You don’t need the technical terms. Just send:
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- The site address and the type of premises
- Any previous report or certificate
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
