AHU cleaning in Marshborough
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. Common call-outs are for stale or musty smells from the ventilation and plant that has been serviced but not cleaned, across heating and cooling coils, dampers and louvres and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Each visit ends with a written report and photos, 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.

Honest limits
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Mechanical faults with motors, belts or bearings
- The supply and extract ducts, quoted separately
- Leaking heating or cooling coils
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before you book.
Parts of the system we cover
- Supply and extract fans
- Drain trays
- Filter sections
- Dampers and louvres
- Internal panels
- Heating and cooling coils
Different parts, different methods
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Leave it or put it right?
Dirt left in an air handling unit does not 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. Somewhere as small as Marshborough, losing a kitchen or building to a fault is felt by everyone who uses it.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or drop us a line, and we’ll talk you through it.

How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- Where the site is and how we reach it
- The times the site is available
- What state the system is in
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
Common questions in Marshborough
Can you come to Marshborough after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Marshborough doesn’t have to lose a day’s trading. Just phone us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Can ventilation in schools around Marshborough be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Marshborough. Send us your term dates when you ring 0345 646 2711 or send us an email, and we will fit the work in.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, so phone us on 0345 646 2711, or email photos to talk it through.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
What types of premises do you cover?
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.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Marshborough buildings and their air
Food Standards Agency data includes about 5 hospitals, care homes and childcare premises within about 1.5 miles of central Marshborough. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.
Wherever a school like Sandwich Technology School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Common problems we fix in Marshborough
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Common reasons sites call us are:
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
- Odours coming through the supply air
- Air handling units due a clean after building work
In Marshborough, we look inside the system before deciding what needs cleaning.

What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. The timing of a visit to Marshborough is set by you, and the travel is our side of the planning.
- 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.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down

Keeping the system healthy
Results last longer with the right care. We suggest:
- Report stiff or damaged access doors
- Don’t ignore odours coming through the grilles
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
