How the job changes from site to site
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
AHU cleaning in Sunninghill, done properly
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers internal panels, supply and extract fans and dampers and louvres, and people most often call us about dirty coils holding back the airflow and plant that needs cleaning after a refit.
For a building near Sunninghill, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What happens if it’s left?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. In a smaller place like Sunninghill, a site that has to close is felt quickly.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
Why us?
- Full insurance on every job
- Each visit written up, with pictures
- We diagnose before we treat
- Out-of-hours work and a 24/7 emergency line
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Sunninghill and across Windsor and Maidenhead. Larger estates can be phased building by building around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Your questions about AHU cleaning in Sunninghill
Do you do school ventilation cleaning in Sunninghill in the summer holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 15 schools, colleges and universities with registered kitchens within about a mile and a half of Sunninghill. You can call 0345 646 2711 or email us with the dates the site is empty.
Can the work in Sunninghill be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Sunninghill needn’t be disturbed. Tell us your opening hours when you ask for a quote.
How long does it take to clean an air handling unit?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
What information do you need?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- The times the site is available
- The size of the system
- Site rules, permits and inductions
- The condition of the system
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Getting to the system matters more than parking in a place like Sunninghill, so let us know how to reach it.
- We agree a shutdown window that suits the building.
- We take before photos 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 pictures are taken and the certificate issued.
Getting ready for the visit
- Clear the space around the work
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms

What else we do in Sunninghill
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
