AHU Cleaning in Snowdown
Our technicians work in Snowdown on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
- Do not ignore odours coming through the grilles
- Note any water around the unit or leaks below it
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
AHU cleaning in Snowdown, done properly
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you’re dealing with air handling units never cleaned inside and dirty filters cutting the airflow, we can put it right, from supply and extract fans, filter sections and internal panels onwards.
For a building in or near Snowdown, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Managing agents and facilities teams in Snowdown
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
How it works
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 the rest is down to us. Before we leave, the area is tidied and the paperwork follows. If the van will struggle with a lane or gateway near Snowdown, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
Getting a quote
To help us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or send us an email.

Fixed quotes for AHU cleaning in Snowdown
Your quote is based on your site. We take into account:
- Travel, parking and unloading
- The condition we find in the survey
- How easy every part is to reach
- Whether several sites go on one quote
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.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

What else we do in Snowdown
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Snowdown questions
Can you get to a site in Snowdown?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you clean school ventilation in Snowdown in the holidays?
Yes, out-of-term visits are normal for schools. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Snowdown. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Different parts, different methods
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Ventilation in Snowdown buildings
Food Standards Agency data includes about 3 schools, colleges and universities and about 3 hospitals, care homes and childcare premises within roughly a mile and a half of the centre of Snowdown.

Snowdown is about 60 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
For schools like St Joseph's Catholic Primary School, the holidays are the usual time to inspect and clean ventilation.

What we are called out for in Snowdown
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Any of these means the system needs a check-up:
- Leaves and litter drawn into the unit
- Dust built up on fan impellers
- Units that have only ever had filter changes
- Filters that are clogged or overdue
If you run an office near Snowdown station, its supply ductwork can gather dust for years before anyone looks inside.
Before you book anyone
- Proof of accreditation you can verify
- Whether a survey comes first
- Whether VAT is included
- Whether the whole system is included, or only the parts that are easy to reach
