AHU cleaning in Upper Halliford
We clean air handling units for buildings in Upper Halliford and across Surrey, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have drain trays holding standing water and air handling units with blocked filters, we can put it right, from internal panels, dampers and louvres and drain trays onwards.
Somewhere as small as Upper Halliford, ducted ventilation is usually 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too in Upper Halliford and across Surrey. Work can be phased by floor, building or site to keep disruption down.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the area around the fresh air intake clear
- Note any water around the unit or leaks below it
- Check the drain tray is emptying during routine visits
- Stick to the filter change plan
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Signs you need AHU cleaning in Upper Halliford
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Common reasons sites call us are:
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
- Stale or musty smells from the ventilation
Workplaces around Upper Halliford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Upper Halliford questions
Can you clean school ventilation in Upper Halliford during the holidays?
Yes, holiday work suits schools best. With about 17 schools and colleges on the FSA’s register within roughly a mile and a half of Upper Halliford, it pays to plan holiday dates ahead. Just call 0345 646 2711 or email us with your term dates and we’ll plan around them.
Will you come out to Upper Halliford?
Yes, we work in villages as well as towns, and Upper Halliford is covered. Let us know about access, parking and anything unusual about getting there when you book.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
How long does it take to clean an air handling unit?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, out of hours if needed.
Can you clean without disrupting the building?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
Can you quote from photos?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Why it’s worth doing now in Upper Halliford
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Rural sites cannot always move to another kitchen or room when something fails.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why us?
- In business since 2009
- Fixed quotes, normally within one working day
- Work around your opening hours, with 24/7 emergency cover
- A written report with pictures after each visit

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
