Your questions about AHU cleaning in York Town
Can you work in York Town outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Is York Town within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
About our AHU cleaning in York Town
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, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris, across filter sections, drain trays and heating and cooling coils.
In a place like York Town, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

When to call us in York Town
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in York Town, that is air they breathe for hours at a time.
Common reasons sites call us are:
- Stale or musty smells from the ventilation
- Dirty fans and fan housings
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
For workplaces around Camberley station with mechanical ventilation, cleaning can be done in the evening or at weekends.

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, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. Evenings, weekends or a closed day all work for a site in a place like York Town.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need
How to get a quote
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or send us an email.

In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Where buildings like these have air handling units, filters, coils and drain trays need regular attention.

Healthcare buildings such as Frimley Park Hospital, about 1.4 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near York Town, yours matters too.

What the work involves, part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- One-off work versus a regular cycle
- Any permits to work or inductions
- What state the system is in
- Working hours and out-of-hours timing
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 explain each part.
What to send for a quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
What AHU cleaning cannot fix
Before you book, it helps to know what’s not included:
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
- A system that’s undersized for the building
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly.
