AHU cleaning in High Halstow
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers dampers and louvres, heating and cooling coils and internal panels, and common reasons people get in touch are odours coming through the supply air and fan sections that haven’t been cleaned in years.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
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.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Signs you need AHU cleaning in High Halstow
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
These are the problems we see most often:
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
If you manage a school such as High Halstow Primary Academy, ventilation cleaning is best booked for the holidays.

What affects the quote in High Halstow
Every site gets its own quote. These are the things that affect it:
- How big the system is
- One-off work versus a regular cycle
- How easy every part is to reach
- The condition of the system
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
For a fixed quote, call 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 typically come back within one working day.
High Halstow: your questions answered
Do you cover smaller places like High Halstow?
Yes. High Halstow is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you offer AHU cleaning in High Halstow?
Yes. Our area runs across London and the South East, High Halstow included. Get in touch with the details and we will arrange a survey.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you have insurance?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
How long does an AHU clean take?
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 give us a ring on 0345 646 2711 or use the quote form to talk it through.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Report musty smells from the vents straight away
- Don’t store bins or materials near the intake
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Somewhere like High Halstow, lanes, gates and parking are worth mentioning in advance.
- 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.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Find the previous report, if there is one
- Clear loose items from the work area
- Mention any parking or loading restrictions
