AHU Cleaning in Midanbury
Our technicians work in Midanbury on air handling unit cleaning. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
The process
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes one overnight shift for many single units, with bigger plant phased. Around Midanbury, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
AHU cleaning for kitchens and businesses in Midanbury
Our AHU cleaning covers sites in Midanbury and the rest of Southampton, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include dirty coils holding back the airflow and intake sections clogged with outdoor debris, across internal panels, dampers and louvres and filter sections.
Visits to a place like Midanbury are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Look at the condensate drain whenever the unit is serviced
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Midanbury buildings and their air
Going by the FSA’s register, there are about 26 schools, colleges and universities, about 41 hospitals, care homes and childcare premises and about 3 hotels and guest houses serving food within about 1.5 miles of central Midanbury. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 1.7 miles south-west of Midanbury is Royal South Hants Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
School buildings such as Bitterne Park School are typically done in the holidays, so classrooms are not disturbed. If you manage offices or shops near Bitterne station, their ventilation can be inspected and cleaned out of hours.

For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Different parts, different methods
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.

What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Honest limits
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly.

Questions from Midanbury
Can you get to a site in Midanbury?
Yes. Villages and rural sites across the South East are part of our work, Midanbury included. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work overnight in Midanbury?
Yes, evening, overnight and weekend work is normal for us. It means the site in Midanbury keeps running as normal. Your opening times are the first thing we ask for.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
How long does an AHU clean take?
The work takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, and you can call us on 0345 646 2711 or use the quote form to plan it.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you need AHU cleaning in Midanbury?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Most sites get in touch when they notice one of these:
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
If you run a surgery, dental practice or care home near Midanbury, clean ventilation matters as much to you as to a hospital like Royal South Hants Hospital (about 1.7 miles south-west).
