AHU cleaning in Towersey
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you have stale or musty smells from the ventilation and air handling units never cleaned inside, we can help.
Work in a small place like Towersey starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Equipment tucked in a roof space or outbuilding near Towersey rarely gets looked at unless someone books it.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Ventilation in Towersey buildings
Food Standards Agency data includes about 3 caring premises (care homes, nurseries and hospitals) in and around Towersey, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. About 40 miles out from central London, Towersey is part of the South East area we work across. The visit is fixed around your opening hours, not ours. For Towersey, the closest hospital is Thame Community Hospital, roughly 1.4 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Thame Community Hospital, about 1.4 miles west, is the nearest hospital to Towersey, and healthcare sites of every size need their supply air kept clean. If you manage a school such as Lord Williams's School, ventilation cleaning is best booked for the holidays.

What affects the cost of AHU cleaning
You will get a fixed price before work begins. It’s based on:
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or email us, and we’ll explain what it covers.
Helping us quote
What to send for a quote:
- Any access panels or hatches you can see
- Problems your staff have spotted
- The postcode and the type of business
- Wide pictures of the system and the area around it
To get a fixed quote, give us a ring on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Towersey, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- 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.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
Advice
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Do not store bins or materials near the intake
- Report musty smells from the vents right away
- File each AHU report in the maintenance log
- Report stiff or damaged access doors
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Questions from Towersey
Is Towersey in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Towersey included. To start, call us on 0345 646 2711 or send us an email with a few pictures of the system.
Can you work in Towersey outside opening hours?
Yes, we can come after you close and finish before you open. The work in Towersey can fit around your hours. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
How long will the unit be out of action?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
