AHU cleaning in Downend
We clean air handling units for buildings in Downend and across West Berkshire, working to TR19® Air, 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. If you are dealing with drain trays holding standing water and dust built up on fan impellers, we can put it right.
Work in a small place like Downend starts with agreeing access and timings.
The paperwork matters as much as the work. You get a written report with photos after each 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.

Questions from Downend
Do you cover smaller places like Downend?
Yes, we work in villages as well as towns, and Downend is covered. Just mention lanes, gates or anything else about the site when you book.
Can you clean school ventilation in Downend during the holidays?
Yes. The holidays are the usual time for school work. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Downend. Just ring 0345 646 2711 or drop us a line with your term dates and we will plan around them.
What information do you need?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How much does AHU cleaning cost in Downend?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Different parts, different methods
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes one overnight shift for many single units, with bigger plant phased. In a small place like Downend, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Let us know when the site is closed or quiet
- Move anything stored near the system
- Let us know about permits to work or site inductions
Getting a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

Ventilation in Downend buildings
Food Standards Agency data includes about 7 schools, colleges and universities in and around Downend, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. West Berkshire Community Hospital is the nearest hospital, about 4.7 miles south of Downend.

The visit is fixed around your opening hours, not ours.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Stick to the filter change plan
- Book the next check in line with the report
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What affects the cost of AHU cleaning
Your quote is based on your site. We consider:
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- The condition we find in the survey
- A single visit or a regular plan
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 we start, so there are no surprises.
What we need to know
There’s no need for technical detail. Just send:
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then ring 0345 646 2711 or send us an email.
Common problems we fix in Downend
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
Keep an eye out for any of the following:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
If you manage a school such as Chieveley Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- Whether the price is fixed
- Which accreditations they hold, and whether you can check them
- Whether the work can be done while the site is closed
- What paperwork you get at the end
What a clean will not put right
We will not sell you work that doesn’t address the problem, so these are the things it won’t cover:
- Dirty ducts beyond the unit itself
- Coils that are corroded or leaking and need replacing
- Controls and BMS settings that run the unit
If in doubt, give us a ring on 0345 646 2711 or email us and we’ll say what we think before booking.
