How we handle AHU cleaning in Turnfurlong
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. Typical jobs include dust-coated heating and cooling coils and stale or musty smells from the ventilation, on supply and extract fans, drain trays and internal panels.
Around a place like Turnfurlong, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
- Make sure the unit’s access doors open easily
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
FAQs for Turnfurlong
Do you work overnight in Turnfurlong?
Yes, evening, overnight and weekend work is normal for us. It means the site in Turnfurlong keeps running as normal. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
Do you clean school ventilation in Turnfurlong in the holidays?
Yes, and it’s the easiest time to do it. There are about 32 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Turnfurlong. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711 or email us with the site type, opening hours and a few pictures.
Why act early in Turnfurlong
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Light use slows the build-up but does not stop it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

What a clean won’t put right

AHU cleaning around Turnfurlong
Going by the FSA’s register, there are about 32 schools, colleges and universities and about 35 caring premises (care homes, nurseries and hospitals) serving food across Turnfurlong and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Turnfurlong, the closest hospital is Stoke Mandeville Hospital, roughly 0.9 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. At about 37 miles from central London, Turnfurlong sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
Workplaces around Aylesbury station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you run a surgery, dental practice or care home near Turnfurlong, clean ventilation matters as much to you as to a hospital like Stoke Mandeville Hospital (about 0.9 miles south). Wherever a school like Turnfurlong Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Different parts, different methods
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
How it works
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. Evenings, weekends or a closed day all work for a site in a place like Turnfurlong.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Have your last certificate or report to hand
- Move anything stored near the system
- Mention any parking or loading restrictions

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
