About our AHU cleaning in Dallington
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Typical jobs include rooms that smell stuffy when the system runs and air handling units due a clean after building work, on heating and cooling coils, drain trays and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Your questions about AHU cleaning in Dallington
Do you work in villages like Dallington?
Yes, Dallington is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you cover Dallington for AHU cleaning?
Yes. We work across London and the South East, and Dallington is part of that. Get in touch with the details and we’ll arrange a survey.
What if parts of the system can’t be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Is a quote from pictures possible?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Will the ventilation be off while you clean?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
What affects the quote in Dallington
The survey tells us what the work involves. We look at:
- Site rules, permits and inductions
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or use the quote form, and we will talk you through it.
What to send for a quote
To help us quote quickly, send us:
- Any access panels or hatches you can see
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
What we do, step by step
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Pictures of the system and its access let us plan the work in Dallington before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Find the previous report, if there is one
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
- Ventilation that was badly designed in the first place
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer.
Parts of the system we cover
- Internal panels
- Dampers and louvres
- Supply and extract fans
- Drain trays
- Filter sections
- Heating and cooling coils
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Make sure the unit’s access doors open easily
- Keep the certificate and photo report with the plant records
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Why act early in Dallington
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Planning a trip to Dallington ahead is easier for everyone than a rushed one.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
