Hannington AHU cleaning
Need AHU cleaning in Hannington? We survey first, send you a fixed quote and work around your opening hours, finishing with a written report and photos.
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
- Leaves and litter drawn into the unit
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Somewhere as small as Hannington, losing a kitchen or building to a fault is felt by everyone who uses it.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

How we handle AHU cleaning in Hannington
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 pictures in a report. The work covers filter sections, drain trays and dampers and louvres, and people most often call us about dust built up on fan impellers and air handling units due a clean after building work.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How it works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Hannington, tell us about narrow lanes, gates and parking when you book.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend

FAQs for Hannington
Will you come out to Hannington?
Yes, Hannington is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Is AHU cleaning available in Hannington?
Yes. Our area runs across London and the South East, Hannington included. Get in touch with the details and we will arrange a survey.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
What a clean won’t put right
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It won’t put right:
- Ventilation that was badly designed in the first place
- Breakdowns that need a mechanical engineer
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer.

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Signs you need AHU cleaning in Hannington
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Leaves and litter drawn into the unit
- Odours coming through the supply air
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
For buildings in and around Hannington, TR19® Air cleaning starts with an inspection.
