AHU cleaning in Purbrook Heath, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. If you are dealing with air handling units due a clean after building work and dust built up on fan impellers, we can help, from filter sections, heating and cooling coils and drain trays onwards.
For a building in or near Purbrook Heath, 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.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Common problems we fix in Purbrook Heath
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Signs it’s time to call us include:
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
Wherever a school like Purbrook Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- When they can work, and whether that is outside your opening hours
- Whether a survey comes first
- Which accreditations they hold, and whether you can check them
- Whether inaccessible sections are listed on the report
Common questions in Purbrook Heath
Can you clean school ventilation in Purbrook Heath during the holidays?
Yes, and it’s the easiest time to do it. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Purbrook Heath, it pays to plan holiday dates ahead. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you work overnight in Purbrook Heath?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Is Purbrook Heath in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Purbrook Heath.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

What a clean will not put right
We’d rather tell you now than book work that will not help, so here are the limits:
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
Where we work
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Dampers and louvres
- Drain trays
- Filter sections
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Report musty smells from the vents right away
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Purbrook Heath run smoothly.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Clear loose items from the work area
How to get a quote

Advice
What your team can do, and what needs us
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 don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
