- Drain trays holding standing water
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
How we handle AHU cleaning in Galleywood
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you have filters that are clogged or overdue and debris and leaves in the fresh air intake, we can help.
In a smaller place like Galleywood, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Fixed quotes for AHU cleaning in Galleywood
There’s no set price list, because no two systems are the same. The quote depends on:
- The number of sites or systems
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
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. Call for a fixed quote and we’ll go through it with you.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- The paperwork from the last visit, if you have it
To get a fixed quote, call us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Galleywood: your questions answered
Do you work at weekends in Galleywood?
Yes, nights and weekends are routine for us. That way a site in Galleywood doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Can ventilation in schools around Galleywood be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Galleywood. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
Is Galleywood in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Galleywood.
How long does it take to clean an air handling unit?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Bigger units can be phased, so give us a ring on 0345 646 2711 or send us an email to talk it through.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
What we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the journey to Galleywood and bring what the job is likely to need.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- 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
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system

Part by part
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.

What we are called out for in Galleywood
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
These are the problems we see most often:
- Odours coming through the supply air
- Drain trays holding standing water
- Leaves and litter drawn into the unit
- Filters that are clogged or overdue
If you manage a school such as St Michael's Church of England Voluntary Aided Junior School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- Whether a survey comes first
- Whether the whole system is included, or only the parts that are easy to reach
- Proof of insurance
- Whether a written report and pictures are included
Why it’s worth doing now in Galleywood
If people in a building in Galleywood complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. A planned visit to Galleywood fits your hours; an emergency doesn’t.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.
