AHU cleaning in Bentley
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you are dealing with air handling units never cleaned inside and plant that needs cleaning after a refit, we can put it right, from filter sections, supply and extract fans and internal panels onwards.
Somewhere as small as Bentley, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Each visit ends with a written report and photos, 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.

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Look at the condensate drain whenever the unit is serviced
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- Do not ignore odours coming through the grilles
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Bentley.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Clear the space around the work

What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.

Common problems we fix in Bentley
Whatever surrounds a building in Bentley, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
It’s time to book a visit if you see:
- Dust built up on fan impellers
- Drain trays holding standing water
- Stale or musty smells from the ventilation
- Dust-coated heating and cooling coils
For schools like Becket Keys Church of England School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- What happens if part of the system cannot be accessed
- What’s included in the scope, part by part
- What paperwork you get at the end
- Whether the work can be done while the site is closed
Managing agents and facilities teams in Bentley
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
What AHU cleaning cannot fix
AHU cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Mechanical faults with motors, belts or bearings
- A system that is undersized for the building
- Leaking heating or cooling coils
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
What the work covers

Common questions in Bentley
Can you come to Bentley after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Bentley does not have to lose a day’s trading. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.

Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.

Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or email us and tell us about the site and its opening hours.

It takes anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
