About our AHU cleaning in Little Heath
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. We’re often asked to deal with odours coming through the supply air and dirty filters cutting the airflow, on heating and cooling coils, drain trays and dampers and louvres.
Around a place like Little Heath, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
Good records are part of the job. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Going by the FSA’s register, there are about 8 schools, colleges and universities and about 15 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Little Heath. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. The nearest hospital to Little Heath is Battle Hospital, about 2.5 miles east.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
- The condition of the system
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
Part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. In a smaller place like Little Heath, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Related advice
Why act early in Little Heath
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A site near Little Heath that has to close at short notice is hard to cover for.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

Looking after it afterwards
So the system stays in good health:
- Flag stale or damp smells in the supply air
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
- File each AHU report in the maintenance log
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Your questions about AHU cleaning in Little Heath
Do you clean school ventilation in Little Heath in the holidays?
Yes, and it’s the easiest time to do it. With about 8 schools and colleges on the FSA’s register within roughly a mile and a half of Little Heath, it pays to plan holiday dates ahead. You can phone us on 0345 646 2711, or email photos with the dates the site is empty.
Do you cover smaller places like Little Heath?
Yes. Little Heath is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
How long does it take to clean an air handling unit?
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, so call 0345 646 2711 or drop us a line to talk it through.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
What we’re called out for in Little Heath
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Clients typically contact us when they notice one of these:
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
Healthcare ventilation, from large hospitals like Battle Hospital (about 2.5 miles east) to small clinics, depends on clean filters, coils and ducts.
