How we handle AHU cleaning in Michelmersh
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers drain trays, supply and extract fans and dampers and louvres, and people most often call us about drain trays holding standing water and leaves and litter drawn into the unit.
In a village or hamlet like Michelmersh, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Why deal with it now?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Out of sight is the usual reason a rural system goes too long without attention.
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. Ask for a fixed quote and we’ll go through it with you.

Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
What AHU cleaning can’t fix
Some problems need a different service or another trade:
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
If in doubt, phone us on 0345 646 2711 or email us and we’ll say what we think before you book.

Your questions about AHU cleaning in Michelmersh
Is Michelmersh in your area for AHU cleaning?
Yes, Michelmersh is covered. A fixed quote usually follows within one working day of the survey details.
Do you cover smaller places like Michelmersh?
Yes, Michelmersh is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Is there a survey before the work?
Yes, every time. 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.
How much does AHU cleaning cost?
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.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Common problems we fix in Michelmersh
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Keep an eye out for any of the following:
- Condensate trays that won’t empty
- Dirty filters cutting the airflow
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
An inspection comes first for any ventilation job around Michelmersh, so the cleaning matches what’s there.

Advice
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
