AHU cleaning for kitchens and businesses in Dry Sandford
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you have filters that are clogged or overdue and air handling units never cleaned inside, we can help, from supply and extract fans, dampers and louvres and heating and cooling coils onwards.
Work in a small place like Dry Sandford starts with agreeing access and timings.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.

Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before booking.

The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. If the van will struggle with a lane or gateway near Dry Sandford, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Can you get to a site in Dry Sandford?
Yes. Villages and rural sites across the South East are part of our work, Dry Sandford included. A survey first, from pictures or a visit, means we arrive with the right kit.

Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.

The work takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, and you can ring 0345 646 2711 or email us to plan it.
Does the AHU have to be shut down for cleaning?
Yes, for the time we are working on it. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.
Signs you need AHU cleaning in Dry Sandford
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Debris and leaves in the fresh air intake
- Blocked condensate drains and slimy trays
If you manage a school such as Dry Sandford Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- What records you will receive afterwards
- Whether the price is fixed
- What hours they’ll be on site
- If they look at the system before pricing
