Air handling unit cleaning in Martyr's Green, Surrey
AHU cleaning for commercial sites in Martyr's Green and across Surrey. CHAS, SafeContractor and ISO 9001, and fully insured.
- Odours coming through the supply air
- Condensate trays that will not empty
- Plant that needs cleaning after a refit
The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes one overnight shift for many single units, with bigger plant phased. A quick note on how to find the site and where to park makes a visit to Martyr's Green run smoothly.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

How we handle AHU cleaning in Martyr's Green
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. The work covers dampers and louvres, filter sections and heating and cooling coils, and people most often call us about blocked condensate drains and slimy trays and dirty fans and fan housings.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Clear leaves and litter away from the intake
- Stick to the filter change plan
- Keep inspection doors on the unit in good order
- Store the TR19 paperwork where auditors can find it
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
Not sure which it is? You can call 0345 646 2711 or use the quote form and we’ll tell you honestly.
What we work on in Martyr's Green
- Heating and cooling coils
- Internal panels
- Drain trays
- Supply and extract fans
- Filter sections
- Dampers and louvres
Why it’s worth doing now in Martyr's Green
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. It’s worth booking a check, because nobody sees inside a duct day to day.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Martyr's Green questions
Do you offer AHU cleaning in Martyr's Green?
Yes, Martyr's Green is covered. Get in touch with the details and we’ll arrange a survey.
Can you work in Martyr's Green outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Martyr's Green needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
How long does it take to clean an air handling unit?
The work takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, and you can call us on 0345 646 2711 or email us to plan it.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What we’re called out for in Martyr's Green
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
What we are most often called out for:
- Air handling units never cleaned inside
- Drain trays holding standing water
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
Healthcare buildings such as Woking Community Hospital, about 5.1 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Martyr's Green, yours matters too.

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Martyr's Green buildings and their air
The FSA’s food hygiene register lists about 3 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service across Martyr's Green and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 20 miles out from central London, Martyr's Green is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Woking Community Hospital is the nearest hospital, about 5.1 miles west of Martyr's Green. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
