AHU cleaning in Dartford, done properly
Our AHU cleans for sites in Dartford cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. If you have units needing a clean before a new tenant or handover and dirty coils holding back the airflow, we can help.
In Dartford, ventilation in schools and offices is cleaned when the building is quiet: evenings, weekends or school holidays.
A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

- Do not store bins or materials near the intake
- Keep the certificate and photo report with the plant records
- Don’t ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Questions from Dartford
Do you offer AHU cleaning in Dartford?
Yes. Our area runs across London and the South East, Dartford included. A fixed quote normally follows within one working day of the survey details.
Can ventilation in schools around Dartford be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Dartford. You can call 0345 646 2711, or email photos with the dates the site is empty.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- Controls and BMS settings that run the unit
- Dirty ducts beyond the unit itself
- Damaged coils beyond cleaning
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before you book.
What the work covers
- Filter sections
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Internal panels
- Dampers and louvres
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building around the people who use them.
