AHU cleaning in Molesey
Our AHU cleaning covers sites in Molesey and the rest of Surrey, 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. The work covers heating and cooling coils, drain trays and internal panels, and common reasons people get in touch are stale or musty smells from the ventilation and air handling units never cleaned inside.
In a place like Molesey, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The paperwork matters as much as the work. You get a written report with photos after every visit, 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.

Part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a smaller place like Molesey, a site that has to close is felt quickly.
What you pay depends on the size of the system, 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.

FAQs for Molesey
Do you clean school ventilation in Molesey in the holidays?
Yes. The holidays are the usual time for school work. Around Molesey, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Will you come out to Molesey?
Yes. Villages and rural sites across the South East are part of our work, Molesey included. Let us know about access, parking and anything unusual about getting there when you book.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
- Make sure condensate is draining away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

What affects the quote in Molesey
Some jobs are bigger than they look, and some smaller. The main factors:
- The condition of the system
- Any permits to work or inductions
- How big the system is
- The times the site is available
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before we start.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Where the site is and what kind of site it is
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
The process
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Everything the job in Molesey needs is worked out beforehand, from the survey.
- 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.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Agree a time when the area can be out of use

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Signs you need AHU cleaning in Molesey
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
If you notice any of these, it’s worth a diagnosis:
- Fan sections that haven’t been cleaned in years
- Debris and leaves in the fresh air intake
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
If you manage a school such as The Orchard Infant School, ventilation cleaning is best booked for the holidays.
