About our AHU cleaning in Cowley
If the units serving a building in Cowley have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Typical jobs include condensate trays that won’t empty and stale or musty smells from the ventilation, across filter sections, internal panels and heating and cooling coils.
Visits to a place like Cowley are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What happens on the day
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. Evenings, weekends or a closed day all work for a site in a place like Cowley.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in

Cowley questions
Do you cover smaller places like Cowley?
Yes, we work in villages as well as towns, and Cowley is covered. Just mention lanes, gates or anything else about the site when you book.
Can you clean school ventilation in Cowley during the holidays?
Yes, and it’s the easiest time to do it. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Cowley. Booking early in the term gives the best choice of holiday dates.
What about areas you cannot get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Can you clean the AHU out of hours?
Yes, if daytime working is not practical. We plan the shutdown window with you.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Why deal with it now?
Stuffy rooms and stale smells in a building in Cowley can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. A site near Cowley that has to close at short notice is hard to cover for.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or email photos, and we’ll explain what it covers.

If you manage a school such as Our Lady's Roman Catholic Primary School, ventilation cleaning is best booked for the holidays.

Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Make sure condensate is draining away
- Do not ignore odours coming through the grilles
- Stick to the filter change plan
- Store the TR19 paperwork where auditors can find it
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
When something else is needed
In fairness, there are a few things this work won’t fix:
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
