AHU cleaning in Burntcommon, done properly
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. We are often asked to deal with units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris, on filter sections, internal panels and dampers and louvres.
In a village or hamlet like Burntcommon, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When the work can happen, such as evenings, overnight or weekends
- What state the system is in
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Asking for a quote
We can often survey from pictures. Try to include:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call 0345 646 2711 or use the quote form.

Do you need AHU cleaning in Burntcommon?
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
Signs it’s time to call us include:
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
School buildings such as Send CofE Primary School are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- Whether the price is fixed
- When the next visit should be, and why
- Whether a written report and pictures are included
- If they look at the system before pricing
Leave it or put it right?
Standing water in a drain tray does not 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. In a place like Burntcommon, ductwork and fans are easy to forget until something goes wrong.
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.

Looking after it afterwards
After the visit, a few habits help the work last:
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
- Stick to the filter change plan
- File each AHU report in the maintenance log
When we’ve 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.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
What a clean won’t put right
Before booking, it helps to know what’s not included:
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think before you book.

How it works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. A few photos of the system help us make the most of a visit to a place like Burntcommon.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload
- Agree a time when the area can be out of use

Burntcommon questions
Can you work in Burntcommon outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Do you do school ventilation cleaning in Burntcommon in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Burntcommon, it pays to plan holiday dates ahead. Just call 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.
Is there a survey before the work?
Yes, every time. 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.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
