What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
AHU cleaning in Pirbright, done properly
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you have dust-coated heating and cooling coils and air handling units with blocked filters, we can put it right, from drain trays, heating and cooling coils and internal panels onwards.
Somewhere as small as Pirbright, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the quote in Pirbright
Your quote is based on your site. We consider:
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
- The postcode and the type of business
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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it 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 Pirbright run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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 pictures are taken and the certificate issued.
Before we arrive
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Let us know about permits to work or site inductions
How to get a quote
Getting a quote does not take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Between visits
Aftercare is simple, and it helps at the next visit:
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Why act early in Pirbright
If people in a building in Pirbright complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Equipment tucked in a roof space or outbuilding near Pirbright rarely gets looked at unless someone books it.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Common questions in Pirbright
Is Pirbright within the area you cover?
Yes, we work in villages as well as towns, and Pirbright is covered. Just mention lanes, gates or anything else about the site when you book.
Is Pirbright in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Pirbright included. A fixed quote usually follows within one working day of the survey details.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Managing agents and facilities teams in Pirbright
