How we handle AHU cleaning in Worplesdon
We clean air handling units for buildings in Worplesdon and across Surrey, working to TR19® Air, in offices, schools, hospitals, care homes and retail. 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-coated heating and cooling coils, we can put it right.
For a building in or near Worplesdon, access is agreed in advance and the visit is planned around the journey.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What the work involves, part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
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.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Worplesdon knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
Get a fixed quote
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, you get a fixed price before work begins.

Common questions in Worplesdon
Is Worplesdon within the area you cover?
Yes. Worplesdon is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Worplesdon?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Worplesdon needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What should I send you?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Signs you need AHU cleaning in Worplesdon
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 the finer material travels on.
Most sites get in touch after spotting something like this:
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Guildford Hospital (about 2.3 miles south) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book
- What insurance they carry
- Exactly which parts of the system are covered
- Whether a written report and photos are included
- Whether the price is fixed
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- Parking and loading at the site
- The times the site is available
- Site requirements such as sign-in and permits
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, call 0345 646 2711, or send details by email.
In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Staff cleaning does not 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.
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. With notice, the visit to Worplesdon can be fitted around your bookings and events.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
