AHU cleaning in Middleton-on-Sea
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you have dirty coils holding back the airflow and debris and leaves in the fresh air intake, we can help, from filter sections, heating and cooling coils and supply and extract fans onwards.
In a smaller place like Middleton-on-Sea, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. Your opening hours decide when we come to Middleton-on-Sea, not ours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Before we arrive
- Clear the space around the work
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions

What AHU cleaning cannot fix
AHU cleaning cannot fix everything, and we’d rather say so up front. It will not put right:
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.
What we work on in Middleton-on-Sea
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Internal panels
- Dampers and louvres
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 don’t reach the grease that builds up further in. That part needs specialist access and equipment.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Fixed quotes for AHU cleaning in Middleton-on-Sea
The price is fixed before any work begins. It takes into account:
- The number of sites or systems
- How big the system is
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
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 are unsure, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Asking for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
- 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.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Questions from Middleton-on-Sea
Can ventilation in schools around Middleton-on-Sea be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Middleton-on-Sea. Booking early in the term gives the best choice of holiday dates.
Will you come out to Middleton-on-Sea?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
What we are called out for in Middleton-on-Sea
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Any of these means the system needs a check-up:
- Air handling units due a clean after building work
- Air handling units with blocked filters
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
Healthcare ventilation, from large hospitals like Bognor Regis War Memorial Hospital (about 2.4 miles west) to small clinics, depends on clean filters, coils and ducts.

Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
