Kingswood: your questions answered
Do you clean school ventilation in Kingswood in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Kingswood. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do you work at weekends in Kingswood?
Yes. We work evenings, overnight and at weekends. The work in Kingswood can fit around your hours. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
How much does AHU cleaning cost in Kingswood?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
How we handle AHU cleaning in Kingswood
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 dampers and louvres, internal panels and drain trays, and common reasons people get in touch are rooms that smell stuffy when the system runs and filters that are clogged or overdue.
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.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Kingswood are booked in advance, at a time that suits whoever runs the site.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- 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.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system
- Tell us about site rules, permits or sign-in
How to get a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
Advice
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Kingswood and across Buckinghamshire. Larger estates can be phased building by building around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Why it’s worth doing now in Kingswood
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Equipment tucked in a roof space or outbuilding near Kingswood rarely gets looked at unless someone books it.
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711, or email photos, and we will explain what it covers.
Why choose Duct Doctor in Kingswood
- Ventilation hygiene specialists since 2009
- One number for every site across the South East and London
- Work around your opening hours, with 24/7 emergency cover
- Accredited under CHAS and SafeContractor, with ISO 9001
Common problems we fix in Kingswood
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Keep an eye out for these warning signs:
- Units that have only ever had filter changes
- Air handling units with blocked filters
- Dirty fans and fan housings
- Condensate trays that won’t empty
School buildings such as Grendon Underwood Combined School are usually done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- When they can work, and whether that’s outside your opening hours
- How VAT is shown on the quote
- Whether they’re fully insured
What affects the cost of AHU cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- The times the site is available
- A single visit or a regular plan
- The scale of the work
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What we need to know
When you contact us, it’s useful to have:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- The times we could work without disrupting the site
To get a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
What AHU cleaning cannot fix
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Heating and cooling coils
- Internal panels
- Filter sections
- Dampers and louvres
- Drain trays
- Supply and extract fans
Keeping the system healthy
So the system stays in good health:
- Book the next check in line with the report
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents right away
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
