AHU cleaning in Cheriton, done properly
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers drain trays, heating and cooling coils and internal panels, and the jobs we see most are air handling units due a clean after building work and coils clogged with dust and debris.
Somewhere as small as Cheriton, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We have 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.

What else we do in Cheriton
How the visit works
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Cheriton.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Questions from Cheriton
Is AHU cleaning available in Cheriton?
Yes, Cheriton is covered. Get in touch with the details and we will arrange a survey.
Do you work in villages like Cheriton?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then phone us on 0345 646 2711, or email photos.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711 or send us an email and tell us about the site and its opening hours.
Can you price the work without visiting?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Signs you need AHU cleaning in Cheriton
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Cheriton, that is air they breathe for hours at a time.
Common reasons sites call us are:
- Odours coming through the supply air
- Debris and leaves in the fresh air intake
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
Wherever a school like Cheriton Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before you book anyone
- Whether they recommend a next date
- What happens if part of the system can’t be accessed
- Whether the quote shows VAT
- Whether a written report and photos are included
Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Fixed quotes for AHU cleaning in Cheriton
Before we fix a price, we need to know a few things. We look at:
- Travel, parking and unloading
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Helping us quote
You don’t need the technical terms. Just send:
- Any access panels or hatches you can see
- Problems your staff have spotted
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Plan the next inspection before the last report gets filed away
- Stick to the filter change plan
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
- Airflow problems caused by the system’s design
If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer.
Where we work
- Heating and cooling coils

For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
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.
