AHU cleaning in Drayton St Leonard, done properly
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with air handling units never cleaned inside and leaves and litter drawn into the unit, we can put it right.
Work in a small place like Drayton St Leonard starts with agreeing access and timings.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common problems we fix in Drayton St Leonard
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Any of these means the system needs a check-up:
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
Healthcare buildings such as Littlemore Hospital, about 5.3 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Drayton St Leonard, yours matters too.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building around the people who use them.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.

Fixed quotes for AHU cleaning in Drayton St Leonard
The price is fixed before any work begins. It’s based on:
- How big the system is
- A single visit or a regular plan

- Working hours and out-of-hours timing
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
What to send for a quote
To speed up the quote, please include:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Change filters on schedule and log each change
- Watch for drips or damp patches near the plant
- Diary the inspection date recommended in the report
- Keep the area around the fresh air intake clear
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

The process

- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
