AHU cleaning in Ashendon, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. The work covers heating and cooling coils, dampers and louvres and filter sections, and the jobs we see most are blocked condensate drains and slimy trays and plant that needs cleaning after a refit.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.

What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Ashendon, let us know and we will plan around it.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, call us on 0345 646 2711 or send us an email.

Keeping the system healthy
To keep the system working properly between visits:
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
- Plan the next inspection before the last report gets filed away
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the 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.
Fixed quotes for AHU cleaning in Ashendon
We quote each job individually. These are the things that affect it:
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
Asking for a quote
What to send for a quote:
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.
Parts of the system we cover
- Filter sections
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Supply and extract fans
