AHU cleaning in Higham
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Typical jobs include air handling units due a clean after building work and stale or musty smells from the ventilation, across filter sections, dampers and louvres and internal panels.
Work in a small place like Higham starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Make sure the unit’s access doors open easily
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Why it’s worth doing now in Higham
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. Equipment tucked in a roof space or outbuilding near Higham rarely gets looked at unless someone books it.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Signs you need AHU cleaning in Higham
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Keep an eye out for any of the following:
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
- Dust built up on fan impellers
- Odours coming through the supply air
Healthcare buildings such as Severalls Hospital, about 5.2 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Higham, yours matters too.

Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When it’s something else
It’s worth knowing the limits before booking:
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before you book.

Different parts, different methods

How it works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. A quick note on how to find the site and where to park makes a visit to Higham run smoothly.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
