How we handle AHU cleaning in Sevington
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, heating and cooling coils and filter sections, and people most often call us about stale or musty smells from the ventilation and dirty coils holding back the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Sevington
There’s no set price list, because sites vary so much. The quote depends on:
- Travel, parking and unloading
- How many systems or sites are involved
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
When you call or email, these details help:
- The site address and the type of premises
- The times we could work without disrupting the site
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
For a fixed quote, call us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
What staff can safely do
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 can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
How the visit works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send photos, we can arrive in Sevington knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then call us on 0345 646 2711 or email us.

- Blocked condensate drains and slimy trays

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Flag stale or damp smells in the supply air
- Check the drain tray is emptying during routine visits
- Keep the certificate and photo report with the plant records
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
