Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Stick to the filter change plan
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
- Check the drain tray is emptying during routine visits
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
AHU cleaning in Shere
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers drain trays, supply and extract fans and heating and cooling coils, and people most often call us about dust built up on fan impellers and plant that has been serviced but not cleaned.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How we price AHU cleaning
We do not publish a price list, because sites vary so much. What we look at:
- The times the site is available
- Site rules, permits and inductions
- The size of the system
- Parking and loading at the site
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
What we need to know
When you contact us, these details help:
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
If you need AHU cleaning in Shere, ring 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send pictures or your last report if you can. A fixed quote normally follows within one working day.
Why it’s worth doing now in Shere
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Shere simpler. A planned visit to Shere is easier to arrange than an emergency callout.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before we start.

What happens on the day
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. A few photos of the system help us make the most of a visit to a place like Shere.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive

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.

Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
