Surrey · Air handling unit cleaning
Byfleet AHU cleaning
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Byfleet, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes anything from half a day for one small unit to several shifts for a plant room full of them. Because the survey comes first, a visit to Byfleet can normally be finished without a second trip.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive

Advice
AHU cleaning in Byfleet, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. Common call-outs are for air handling units due a clean after building work and dust-coated heating and cooling coils, across internal panels, filter sections and supply and extract fans.
Around a place like Byfleet, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What AHU cleaning looks like in Byfleet
Going by the FSA’s register, there are about 4 schools, colleges and universities and about 10 care, childcare and hospital premises serving food within about 1.5 miles of central Byfleet. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Byfleet, the closest hospital is Runnymede Hospital, roughly 3.5 miles north-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. We cover Byfleet, about 20 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
If you run an office near Byfleet & New Haw station, its supply ductwork can gather dust for years before anyone looks inside. Healthcare buildings such as Runnymede Hospital, about 3.5 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Byfleet, yours matters too. For schools like St Mary's CofE Controlled Primary School, the holidays are the usual time to inspect and clean ventilation.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
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, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Byfleet: your questions answered
Do you clean school ventilation in Byfleet in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Byfleet. Booking early in the term gives the best choice of holiday dates.
Can you come to Byfleet after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Byfleet needn’t be disturbed. Your opening times are the first thing we ask for.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What information do you need?
Some photos and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
How long does it take to clean an air handling unit?
Expect it to take from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
More services for Byfleet
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Fixed quotes for AHU cleaning in Byfleet
We do not publish a price list, because sites vary so much. What we look at:
- When the work can happen, such as evenings, overnight or weekends
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
- What state the system is in
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
What we need to know
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
