What staff can safely do
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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
AHU cleaning in Sharnal Street, done properly
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you’re dealing with odours coming through the supply air and dust-coated heating and cooling coils, we can put it right, from internal panels, filter sections and drain trays onwards.
In a village or hamlet like Sharnal Street, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Sharnal Street run smoothly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Mention any parking or loading restrictions
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
Getting a quote
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, you get a fixed price before we start.

Fixed quotes for AHU cleaning in Sharnal Street
A fixed price needs a few facts first. We look at:
- How many systems or sites are involved
- The times the site is available
- The condition of the system
- How big the system is
Whatever the type of site, the quote works 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.
Asking for a quote
To speed up the quote, please include:
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
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. Add the site type and your opening hours, and we can price many jobs without a visit.

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Do you need AHU cleaning in Sharnal Street?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
If you notice any of these, it’s worth a diagnosis:
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
- Drain trays holding standing water
- Units that have only ever had filter changes
Wherever a school like High Halstow Primary Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Keep filter changes on time and recorded
- Diary the inspection date recommended in the report
- Note any water around the unit or leaks below it
- Do not store bins or materials near the intake
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Sharnal Street questions
Will you come out to Sharnal Street?
Yes. Villages and rural sites across the South East are part of our work, Sharnal Street included. Photos of the system and directions to the site help us plan the visit.
Do you cover Sharnal Street for AHU cleaning?
Yes, Sharnal Street is within the area we cover across London and the South East. You can give us a ring on 0345 646 2711 or send us an email and tell us what needs doing.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or email us with the site type, opening hours and a few photos.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or send us an email for straight advice and a fixed quote.
