In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
How we handle AHU cleaning in Widdington
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers supply and extract fans, internal panels and drain trays, and the jobs we see most are plant that has been serviced but not cleaned and units needing a clean before a new tenant or handover.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

FAQs for Widdington
Can you get to a site in Widdington?

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Widdington needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
How much does AHU cleaning cost in Widdington?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
How long does an AHU clean take?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.

Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Planning a trip to Widdington ahead is easier for everyone than a rushed one.
Putting the work off seldom saves money. 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 email photos for straight advice and a fixed quote.

What the work involves, part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
When to call us in Widdington
Whatever surrounds a building in Widdington, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
It’s time to book a visit if you see:
- Dust-coated heating and cooling coils
- Filters that are clogged or overdue
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Saffron Walden Community Hospital (about 4.4 miles north) to small clinics, depends on clean filters, coils and ducts.

What a clean won’t put right
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
If you’re not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
What we work on in Widdington
- Heating and cooling coils
- Internal panels
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Drain trays
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Don’t ignore odours coming through the grilles
- Do not store bins or materials near the intake
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
