How we handle AHU cleaning in Shellow Bowells
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers filter sections, supply and extract fans and drain trays, and the jobs we see most are air handling units due a clean after building work and air handling units never cleaned inside.
Work in a small place like Shellow Bowells starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

The process
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Shellow Bowells, tell us about narrow lanes, gates and parking when you book.
- 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.
Before we arrive
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

Signs you need AHU cleaning in Shellow Bowells
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 Shellow Bowells, that is air they breathe for hours at a time.
It’s time to book a visit if you see:
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Plant that needs cleaning after a refit
Hospitals such as Chelmsford and Essex Hospital (about 5.7 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Shellow Bowells are no different.

Yes, out-of-hours work is a big part of what we do. The work in Shellow Bowells can fit around your hours. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you work in villages like Shellow Bowells?
Yes, we work in villages as well as towns, and Shellow Bowells is covered. Let us know about access, parking and anything unusual about getting there when you book.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
How long does it take to clean an air handling unit?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, and you can call 0345 646 2711, or email photos to plan it.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.

Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Why it’s worth doing now in Shellow Bowells
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.

Aftercare tips
So the system stays in good health:
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
- Report stiff or damaged access doors
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
What affects the quote in Shellow Bowells
Every site gets its own quote. These are the things that affect it:
- How many systems or sites are involved
- A single visit or a regular plan
- Working hours and out-of-hours timing
- How easy every part is to reach
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
What we need to know
When you call or email, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- The site address and the type of premises
- Wide photos of the system and the area around it
- The paperwork from the last visit, if you have it
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
