AHU cleaning in Cootham
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, with the unit switched off and made safe first. The work covers internal panels, heating and cooling coils and dampers and louvres, and the jobs we see most are odours coming through the supply air and plant that has been serviced but not cleaned.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Photos of the system and how to reach it help us plan a visit to Cootham.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, ring 0345 646 2711 or send us an email.
Related advice
What we are called out for in Cootham
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
The symptoms we are asked about most are:
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
In Cootham, we look inside the system before deciding what needs cleaning.
Questions to ask before you book
- When they can work, and whether that is outside your opening hours
- What records you will receive afterwards
- What happens if part of the system can’t be accessed
- Proof of insurance
Cootham: your questions answered
Do you cover smaller places like Cootham?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you work in Cootham outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Cootham can fit around your hours. Your opening times are the first thing we ask for.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
How much does AHU cleaning cost in Cootham?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, typically ready within one working day.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
How long will the unit be out of action?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, including evenings or weekends.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

Managing agents and facilities teams in Cootham
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
What a clean won’t put right
To be straight with you, there are a few things this work will not fix:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
If you’re not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer.

Leave it or put it right?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Somewhere as small as Cootham, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

Looking after it afterwards
To keep the system working properly between visits:
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
