AHU cleaning for kitchens and businesses in Dedworth
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with debris and leaves in the fresh air intake and stale or musty smells from the ventilation, we can help.
Around a place like Dedworth, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Watch for drips or damp patches near the plant
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
- Plan the next inspection before the last report gets filed away
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.

Advice
How we price AHU cleaning
A fixed price needs a few facts first. We check:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- A single visit or a regular plan
- The times the site is available
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
What we need to know
You don’t need the technical terms. Just send:
- A few general shots of the system
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Why it’s worth doing now in Dedworth
Stuffy rooms and stale smells in a building in Dedworth can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. It’s easy to lose track of when the work was last done on a quieter site.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Why book with us
- Every visit written up, with photos
- In business since 2009
- Out-of-hours work and a 24/7 emergency line
- We diagnose before we treat

Your questions about AHU cleaning in Dedworth
Do you work at weekends in Dedworth?
Yes, out-of-hours work is a big part of what we do. That way a site in Dedworth doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in Dedworth in the summer holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 23 schools and colleges with food registrations within roughly a mile and a half of Dedworth. Just call 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, so ring 0345 646 2711, or email photos to talk it through.

Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Different parts, different methods
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
Managing agents and facilities teams in Dedworth
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
We also work for facilities teams across offices, schools and healthcare across Windsor and Maidenhead. Larger estates can be phased building by building to keep disruption down.
