AHU cleaning in Winnersh, done properly
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers heating and cooling coils, internal panels and filter sections, and people most often call us about dirty fans and fan housings and air handling units with blocked filters.
Smaller buildings around Winnersh often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Between visits
Once we have finished, these simple steps help:
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
- Note any water around the unit or leaks below it
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Questions from Winnersh
Can the work in Winnersh be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Winnersh keeps running as normal. Your opening times are the first thing we ask for.
Do you cover smaller places like Winnersh?
Yes, we work in villages as well as towns, and Winnersh is covered. Photos of the system and directions to the site help us plan the visit.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
When something else is needed
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Faulty motors, drives or bearings
- Dirty ducts beyond the unit itself
- Ventilation that was badly designed in the first place
If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer before booking.

Fixed quotes for AHU cleaning in Winnersh
The survey tells us what the work involves. The main factors are:
- One-off work versus a regular cycle
- The condition we find in the survey
- How easy every part is to reach
- Site requirements such as sign-in and permits
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Do you need AHU cleaning in Winnersh?
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 some travels further into the unit.
If you notice any of these, it’s worth a diagnosis:
- Drain trays holding standing water
- Dirty filters cutting the airflow
- Rooms that smell stuffy when the system runs
- Plant that needs cleaning after a refit
Workplaces around Winnersh station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- Proof of insurance
- How VAT is shown on the quote
- Whether a written report and photos are included
Managing agents and facilities teams in Winnersh
We also work for facilities teams across offices, schools and healthcare across Wokingham. Work can be phased by floor, building or site to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
