About our AHU cleaning in Durford Wood
Our AHU cleaning covers sites in Durford Wood and the rest of Hampshire, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you’re dealing with leaves and litter drawn into the unit and dust built up on fan impellers, we can put it right.
Somewhere as small as Durford Wood, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Common questions in Durford Wood
Do you cover smaller places like Durford Wood?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you offer AHU cleaning in Durford Wood?
Yes. We work across London and the South East, and Durford Wood is part of that. To start, phone us on 0345 646 2711 or use the quote form with a few photos of the system.
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.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How long will the unit be out of action?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
What happens to the waste?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Signs you need AHU cleaning in Durford Wood
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
It’s time to book a visit if you see:
- Plant that has been serviced but not cleaned
- Dust built up on fan impellers
- Odours coming through the supply air
- Condensate trays that will not empty
If you manage a school such as Liss Infant School, ventilation cleaning is best booked for the holidays.
What your quote should include

- Whether the quote shows VAT
- What insurance they carry
How we price AHU cleaning
We don’t publish a price list, because sites vary so much. The quote depends on:
- Whether several sites go on one quote
- The scale of the work
- The condition we find in the survey
- Working hours and out-of-hours timing
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Wide pictures of the system and the area around it
- Problems your staff have spotted
Getting a quote does not take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Why it’s worth doing now in Durford Wood
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Systems in rural buildings are often out of sight and out of mind.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
Why Durford Wood businesses choose us
- One number for every site across the South East and London
- Survey first, then a fixed quote
- Fully insured
- Evenings, overnight and weekends, plus 24/7 emergency callout

How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Seeing the system in photos first means the trip to Durford Wood can be planned properly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
Ask for a quote
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, the quote is fixed before any work is booked.
