AHU cleaning in Fairstead
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, so cleaning the unit matters as much as cleaning the ducts. We are often asked to deal with debris and leaves in the fresh air intake and condensate trays that won’t empty, across drain trays, heating and cooling coils and dampers and louvres.
Work in a small place like Fairstead starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.

What else we do in Fairstead
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Fairstead and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
To get a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll usually have a quote within one working day.
Related advice
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. Systems in rural buildings are often out of sight and out of mind.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before we start.

Common questions in Fairstead
Do you work at weekends in Fairstead?
Yes, evening, overnight and weekend work is normal for us. The work in Fairstead can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you get to a site in Fairstead?
Yes, Fairstead is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
What happens to the waste?
We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What AHU cleaning can’t fix
We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.
Parts of the system we cover
- Supply and extract fans

Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
The symptoms we’re asked about most are:
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
- Dust-coated heating and cooling coils
- Plant that has been serviced but not cleaned
If you manage a school such as Terling Church of England Voluntary Aided Primary School, ventilation cleaning is best booked for the holidays.
