About our AHU cleaning in Wormley
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. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have dust built up on fan impellers and plant that has been serviced but not cleaned, we can help, from heating and cooling coils, drain trays and internal panels onwards.
Somewhere as small as Wormley, 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.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
What affects the quote in Wormley
Sites vary more than people expect. The main factors:
- How many systems or sites are involved
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- What state the system is in
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
What to send for a quote
What to send for a quote:
- The site address and the type of premises
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
If you need AHU cleaning in Wormley, call us on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We normally send a fixed quote within one working day.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Leave it or put it right?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Rural sites can’t always move to another kitchen or room when something fails.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.

FAQs for Wormley
Do you work at weekends in Wormley?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Can you get to a site in Wormley?
Yes, Wormley is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
How much does AHU cleaning cost in Wormley?
Every site is different, so each gets its own fixed quote. To get one, ring 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
How long will the unit be out of action?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
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 photos, so records stay tidy.

About 2.3 miles north of Wormley is Milford 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. We cover Wormley, about 35 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible.
If you manage shops or offices close to Witley station, a TR19® Air inspection shows whether the ductwork needs cleaning.
