What we’re called out for in St Mary Hoo
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in St Mary Hoo, that is air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Intake sections clogged with outdoor debris
- Condensate trays that will not empty
- Air handling units due a clean after building work
- Odours coming through the supply air
Healthcare ventilation, from large hospitals like Medway Maritime Hospital (about 6 miles south-west) to small clinics, depends on clean filters, coils and ducts.

About our AHU cleaning in St Mary Hoo
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have dust-coated heating and cooling coils and plant that has been serviced but not cleaned, we can put it right, from drain trays, internal panels and dampers and louvres onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What else we do in St Mary Hoo
How we price AHU cleaning
You’ll get a fixed price before we start. It’s based on:
- The number of sites or systems
- How easy every part is to reach
- What state the system is in
- The size of the system
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
What we need to know
There’s no need for technical detail. It helps if you can send:
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
To get a fixed quote, call us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.

Keeping the system healthy
So the system stays in good health:
- Don’t store bins or materials near the intake
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Your questions about AHU cleaning in St Mary Hoo
Do you work in villages like St Mary Hoo?
Yes, St Mary Hoo is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work overnight in St Mary Hoo?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What happens if you cannot reach some of it?
We record them on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. Seeing the system in pictures first means the trip to St Mary Hoo can be planned properly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Tell us where we can park and unload
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
Ask for a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711 or email us.
Advice
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. It’s worth booking a check, because nobody sees inside a duct day to day.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
