AHU cleaning for Mottisfont and the surrounding area: a survey, a fixed price, careful work and proper paperwork. Call for a fixed quote.
- Leaves and litter drawn into the unit
- Drain trays holding standing water
- Coils clogged with dust and debris
How we price AHU cleaning
The diagnosis comes before the price. We look at:
- One-off work versus a regular cycle
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- How big the system is
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
What to send for a quote
What to send for a quote:
- Any access panels or hatches you can see
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it
The quickest way to a quote is to send pictures: 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 we can price many jobs without a visit.
AHU cleaning for kitchens and businesses in Mottisfont
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have filters that are clogged or overdue and drain trays holding standing water, we can help.
In a village or hamlet like Mottisfont, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Mottisfont: your questions answered
Do you offer AHU cleaning in Mottisfont?
Yes, Mottisfont is covered. You can ring 0345 646 2711, or email photos and let us know what needs doing.
Do you work in villages like Mottisfont?
Yes. Villages and rural sites across the South East are part of our work, Mottisfont included. Let us know about access, parking and anything unusual about getting there when you book.
How do you 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.
What does TR19 mean?
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.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
How long will the unit be out of action?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Facilities teams in offices, schools and healthcare sites book us too in Mottisfont and across Hampshire. Work can be phased by floor, building or site around the people who use them.

Between visits
So the system stays in good health:
- Don’t ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Check the drain tray is emptying during routine visits
- Stick to the filter change plan
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. 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 instead of leaving it to guesswork.

Do you need AHU cleaning in Mottisfont?
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
It’s time to book a visit if you see:
- Dirty fans and fan housings
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
Healthcare ventilation, from large hospitals like Romsey Community Hospital (about 4 miles south-east) to small clinics, depends on clean filters, coils and ducts.

How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. The timing of a visit to Mottisfont is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- 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.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
How to get a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, phone us on 0345 646 2711, or email photos.
Advice
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
