AHU cleaning in Thurnham
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers supply and extract fans, dampers and louvres and filter sections, and common reasons people get in touch are air handling units due a clean after building work and blocked condensate drains and slimy trays.
Somewhere as small as Thurnham, ducted ventilation is normally 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 paperwork matters as much as the work. You get a written report with pictures after every 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 to hand when an insurer or inspector asks.

Common questions in Thurnham
Can you work in Thurnham outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Thurnham needn’t be disturbed. Your opening times are the first thing we ask for.
Do you cover smaller places like Thurnham?
Yes. Thurnham is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll typically reply within one working day.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Do you survey before quoting?
Yes, always. 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.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Between visits
So the system stays in good health:
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
The process
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Thurnham knowing what to expect.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
- Clear the space around the work

Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. It’s worth booking a check, because nobody sees inside a duct day to day.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Different parts, different methods
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
What we are called out for in Thurnham
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Thurnham, that is air they breathe for hours at a time.
It’s time to book a visit if you see:
- Units that have only ever had filter changes
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
- Leaves and litter drawn into the unit
Hospitals such as KIMS hospital (about 1.4 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Thurnham are no different.
