About our AHU cleaning in Lower Upnor
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. Typical jobs include units needing a clean before a new tenant or handover and dirty filters cutting the airflow, on internal panels, supply and extract fans and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Nothing is signed off by word of mouth: 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.

Why act early in Lower Upnor
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. In a place like Lower Upnor, ductwork and fans are easy to forget until something goes wrong.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Why book with us
- We are fully insured
- Accredited under CHAS and SafeContractor, with ISO 9001

Fixed quotes for AHU cleaning in Lower Upnor
You will get a fixed price before we start. It takes into account:
- The condition of the system
- Travel, parking and unloading
- The times the site is available
- Site rules, permits and inductions
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
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 photos, get a survey first. Either way, you get a fixed price before any work starts.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Make sure condensate is draining away
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
- Store the TR19 paperwork where auditors can find it
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Lower Upnor questions
Will you come out to Lower Upnor?
Yes, we work in villages as well as towns, and Lower Upnor is covered. Just mention lanes, gates or anything else about the site when you book.
Do you do school ventilation cleaning in Lower Upnor in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 11 schools and colleges with food registrations within roughly a mile and a half of Lower Upnor. Booking early in the term gives the best choice of holiday dates.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Can you clean the AHU out of hours?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Common problems we fix in Lower Upnor
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Most sites get in touch after spotting something like this:
- Coils clogged with dust and debris
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Dust built up on fan impellers
Hospitals such as French Hospital (about 1.9 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lower Upnor are no different.
What your quote should include
- Whether the figure could change on the day
- When they can work, and whether that is outside your opening hours
- Whether a written report and pictures are included
