AHU cleaning in South Alkham
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include odours coming through the supply air and condensate trays that won’t empty, across supply and extract fans, filter sections and heating and cooling coils.
Somewhere as small as South Alkham, 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.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

When something else is needed
A few issues sit outside what this work can do:
- Leaking heating or cooling coils
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.
Parts of the system we cover
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Internal panels
- Drain trays
- Supply and extract fans
How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Why act early in South Alkham
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 South Alkham simpler. It’s worth booking a check, because nobody sees inside a duct day to day.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

In-house cleaning or a specialist?
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’ll take a look and send you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Common problems we fix in South Alkham
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us include:
- Dirty coils holding back the airflow
- Air handling units with blocked filters
- Leaves and litter drawn into the unit
- Units needing a clean before a new tenant or handover
Ventilation work in and around South Alkham is risk-based: inspect, then clean what needs it.
What your quote should include
- What happens if part of the system cannot be accessed
- Whether they’re fully insured
- Whether the price is fixed
- Whether a written report and pictures are included
