What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
AHU cleaning in Church Town
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with plant that has been serviced but not cleaned and fan sections that haven’t been cleaned in years, we can help, from heating and cooling coils, drain trays and supply and extract fans onwards.
For a building in or near Church Town, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

When to call us in Church Town
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Church Town, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
Foetal Alcohol Spectrum Disorders Clinic, about 2.4 miles east, is the nearest hospital to Church Town, and healthcare sites of every size need their supply air kept clean.
Before you book anyone
- Proof of accreditation you can verify
- What hours they’ll be on site
- Exactly which parts of the system are covered
- Whether they recommend a next date
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Don’t store bins or materials near the intake
- Watch for drips or damp patches near the plant
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Why act early in Church Town
If people in a building in Church Town complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. In a place like Church Town, ductwork and fans are easy to forget until something goes wrong.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
