About our AHU cleaning in Chawley
Coils are where a lot of the dirt ends up. 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 are not flattened. The work covers internal panels, filter sections and supply and extract fans, and common reasons people get in touch are condensate trays that won’t empty and plant that needs cleaning after a refit.
For a building in or near Chawley, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Signs you need AHU cleaning in Chawley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Look out for these warning signs:
- Air handling units never cleaned inside
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
If you run a surgery, dental practice or care home near Chawley, clean ventilation matters as much to you as to a hospital like Radcliffe Infirmary (about 3 miles north-east).

What AHU cleaning looks like in Chawley
Food Standards Agency records list about 3 schools, colleges and universities and about 4 hospitals, care homes and childcare premises registered as food businesses across Chawley and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. The nearest hospital to Chawley is Radcliffe Infirmary, about 3 miles north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 55 miles out from central London, Chawley is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
For schools like Cumnor Church of England School (Voluntary Controlled), the holidays are the usual time to inspect and clean ventilation.

What happens if it’s left?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Rural sites can’t always move to another kitchen or room when something fails.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Chawley: your questions answered
Do you clean school ventilation in Chawley in the holidays?
Yes. The holidays are the usual time for school work. Around Chawley, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Will you come out to Chawley?
Yes, Chawley is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Are you fully insured?
Yes. Full insurance covers our work and have been trading since 2009.
What’s included in an AHU clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
How long does it take to clean an air handling unit?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.

What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Chawley, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system

Advice
Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Make sure condensate is draining away
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
