AHU cleaning in Fairford Leys
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with dirty coils holding back the airflow and drain trays holding standing water, we can put it right, from internal panels, drain trays and dampers and louvres onwards.
For a building near Fairford Leys, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When something else is needed
In fairness, there are a few things this work will not fix:
- Coils that are corroded or leaking and need replacing
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
If in doubt, call 0345 646 2711 or drop us a line and we’ll say what we think.
What the work covers
- Filter sections
- Heating and cooling coils
- Drain trays
- Internal panels
- Dampers and louvres
- Supply and extract fans
What we’re called out for in Fairford Leys
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
These are the problems we see most often:
- Drain trays holding standing water
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Royal Buckinghamshire Hospital (about 1 mile east) to small clinics, depends on clean filters, coils and ducts.

What we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes one overnight shift for many single units, with bigger plant phased. For a place like Fairford Leys, we load the van from the survey notes so the work can be done in one visit where possible.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Clear the space around the work
- Let us know about permits to work or site inductions
- Find the previous report, if there is one

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Your questions about AHU cleaning in Fairford Leys
Is Fairford Leys within the area you cover?
Yes, Fairford Leys is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can the work in Fairford Leys be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Fairford Leys does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
What affects the quote in Fairford Leys
Your quote is based on your site. We take into account:
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
- The condition of the system
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.
Helping us quote
When you call or email, these details help:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
Getting a quote does not take long. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When your team notices a problem 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’ll take a look and send you a fixed quote.
What the work involves, part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
