Air handling unit cleaning in Ramsden, Oxfordshire
AHU cleaning for Ramsden, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
- Fan sections that haven’t been cleaned in years
How we handle AHU cleaning in Ramsden
If the units serving a building in Ramsden have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you have fan sections that haven’t been cleaned in years and coils clogged with dust and debris, we can help, from heating and cooling coils, supply and extract fans and dampers and louvres onwards.
For a building in or near Ramsden, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Check the drain tray is emptying during routine visits
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- Don’t store bins or materials near the intake
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What else we do in Ramsden
What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
- How many systems or sites are involved
- The condition of the system
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
To get a fixed quote, phone us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
How the visit works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Ramsden before we set off.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- 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
- Make sure someone can let us in and lock up afterwards
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What should I send you?

Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you clean the AHU out of hours?
Yes, if daytime working is not practical. We plan the shutdown window with you.

Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What we’re called out for in Ramsden
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Look out for any of the following:
- Leaves and litter drawn into the unit
- Plant that needs cleaning after a refit
- Odours coming through the supply air
- Dust-coated heating and cooling coils
If you manage a school such as Finstock Church of England Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- Whether the work can be done while the site is closed
- Which accreditations they hold, and whether you can check them
- What insurance they carry
- What happens if part of the system cannot be accessed
Why it’s worth doing now in Ramsden
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Equipment tucked in a roof space or outbuilding near Ramsden rarely gets looked at unless someone books it.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
