Air handling unit cleaning in Middleton, Hampshire
AHU cleaning for Middleton, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Coils clogged with dust and debris
- Dust built up on fan impellers
- Odours coming through the supply air
How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like Middleton are booked in advance, at a time that suits whoever runs the site.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
- Clear the space around the work
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
AHU cleaning in Middleton
Our AHU cleaning covers sites in Middleton and the rest of Hampshire, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include stale or musty smells from the ventilation and air handling units never cleaned inside, on internal panels, filter sections and supply and extract fans.
For a building in or near Middleton, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
- File each AHU report in the maintenance log
- 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 pictures. They belong in the plant or maintenance log.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Middleton buildings and their air
At about 60 miles from central London, Middleton sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. Middleton’s nearest hospital, Andover War Memorial Hospital, is about 4.8 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you manage a school such as Longparish Church of England Primary School, ventilation cleaning is best booked for the holidays.
Middleton is about 4 miles east of Andover, in Hampshire. We carry out AHU cleaning for commercial premises of every kind in Middleton and the rest of Hampshire. Middleton is one of 683 places in Hampshire where we work for commercial clients. Our Southampton page covers sites nearby, about 19 miles away.

Middleton questions
Do you work in villages like Middleton?
Yes, Middleton is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you work in Middleton outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Middleton needn’t be disturbed. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
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 often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
Signs you need AHU cleaning in Middleton
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
What we are most often called out for:
- Rooms that smell stuffy when the system runs
- Coils clogged with dust and debris
- Units needing a clean before a new tenant or handover
- Blocked condensate drains and slimy trays
Healthcare buildings such as Andover War Memorial Hospital, about 4.8 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Middleton, yours matters too.

Why act early in Middleton
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. It’s worth booking a check, because nobody sees inside a duct day to day.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form, and we will explain what it covers.
Why book with us
- Fixed quotes from a survey or pictures
- Out-of-hours work and a 24/7 emergency line
- A written report with photos after every visit
- Fully insured

How the job changes from site to site
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.

Fixed quotes for AHU cleaning in Middleton
The quote reflects the site in front of us. We consider:
- Travel, parking and unloading
- How many systems or sites are involved
- Whether we need access equipment or extra panels
- Any permits to work or inductions
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.
Helping us quote
To speed up the quote, please include:
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or drop us a line.
Honest limits
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
- A system that’s undersized for the building
