How we handle AHU cleaning in Tyler's Green
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. Typical jobs include stale or musty smells from the ventilation and fan sections that haven’t been cleaned in years, across dampers and louvres, supply and extract fans and heating and cooling coils.
Somewhere as small as Tyler's Green, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What affects the quote in Tyler's Green
There’s no set price list, because no two systems are the same. The quote depends on:
- How big the system is
- One-off work versus a regular cycle
- Parking and loading at the site
- Any permits to work or inductions
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or drop us a line, and we’ll explain what it covers.
Asking for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Wide photos of the system and the area around it
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, call us on 0345 646 2711 or email us.
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. It takes a single shift for a typical unit, longer for large or heavily soiled ones, 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 Tyler's Green.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Managing agents and facilities teams in Tyler's Green
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
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.
Questions from Tyler's Green
Is Tyler's Green within the area you cover?
Yes, Tyler's Green is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you come to Tyler's Green after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Tyler's Green keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then phone us on 0345 646 2711 or drop us a line.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much does AHU cleaning cost in Tyler's Green?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.
Is a quote from photos possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
When it’s something else
AHU cleaning cannot fix everything, and we’ll tell you before we start. It doesn’t solve:
- Mechanical faults with motors, belts or bearings
- Leaking heating or cooling coils
- Airflow problems caused by the system’s design
If in doubt, ring 0345 646 2711, or email photos and we will say what we think.
Parts of the system we cover
- Heating and cooling coils
- Filter sections
- Internal panels
- Dampers and louvres
- Drain trays
- Supply and extract fans
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Make sure condensate is draining away
- Don’t ignore odours coming through the grilles
- Keep filter changes on time and recorded
- File each AHU report in the maintenance log
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.

Busy, occupied buildings like these are where clean supply air matters most. About 2.2 miles north-west of Tyler's Green is Caterham Dene Hospital, the nearest hospital.

Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
