AHU cleaning in Stone Cross, done properly
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers supply and extract fans, heating and cooling coils and drain trays, and people most often call us about condensate trays that won’t empty and leaves and litter drawn into the unit.
Work in a small place like Stone Cross starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part

Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.

Leave it or put it right?
Stuffy rooms and stale smells in a building in Stone Cross can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. It’s worth booking a check, because nobody sees inside a duct day to day.
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 choose Duct Doctor in Stone Cross
- CHAS, SafeContractor and ISO 9001
- Ventilation hygiene specialists since 2009
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Full insurance on every job
Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Check the drain tray is emptying during routine visits
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Report musty smells from the vents right away
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

The symptoms we’re asked about most are:
