AHU cleaning in Arreton, done properly
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you have air handling units never cleaned inside and units needing a clean before a new tenant or handover, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Your questions about AHU cleaning in Arreton
Can you work in Arreton outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Is AHU cleaning available in Arreton?
Yes. Our area runs across London and the South East, Arreton included. A fixed quote usually follows within one working day of the survey details.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
How long does an AHU clean take?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
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.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Arreton before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Advice
What else we do in Arreton
What AHU cleaning can’t fix
In fairness, there are a few things this work won’t fix:
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
If you’re not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer.
What we work on in Arreton
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Internal panels
Part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Don’t store bins or materials near the intake
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents straight away
- Keep the certificate and photo report with the plant records
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
AHU cleaning around Arreton
About 2.9 miles west of Arreton is Whitecroft Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
In Arreton, we look inside the system before deciding what needs cleaning.
Arreton is about 3 miles south-east of Newport, in the Isle of Wight. Arreton gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Arreton is one of 125 towns, villages and districts in the Isle of Wight we cover for commercial clients. We also work in Portsmouth, about 12 miles from Arreton.
Our technicians cover all of the PO30 postcode area for AHU cleaning and the streets around it. AHU cleaning is available to premises on Cherrywood View, Hopkins Walk and Hazely Combe and the roads around them. Close by, we work in Merstone (1 mile south-west), Downend (1 mile north), Hale Common (1 mile south), Newchurch (1 mile south-east) and Branstone (2 miles south-east). We also work in nearby towns such as Newport (3 miles north-west), Ryde (5 miles north-east), Cowes (7 miles north-west), Sandown (4 miles east), Shanklin (4 miles south-east) and Ventnor (5 miles south). If your site is somewhere remote, the visit takes a little more planning, so mention it when you ask for a quote.
What’s near Arreton
Locally, jobs take us to businesses close to The White Lion pub, among other places. The closest station to Arreton is Sandown station, about 3.4 miles east of the centre. Nearby you will also find Museum of Country And Agriculture (0.5 miles south-east) and Carisbrooke Castle (3.5 miles west). Not far away are Alverstone Mead and Brading Down.
What affects the quote in Arreton
Some jobs are bigger than they look, and some smaller. What affects the quote:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- How many systems or sites are involved
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
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.
What we’re called out for in Arreton
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
It’s time to book a visit if you see:
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
- Rooms that smell stuffy when the system runs
Hospitals such as Whitecroft Hospital (about 2.9 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Arreton are no different.
Before booking anyone
- What insurance they carry
- When they can work, and whether that’s outside your opening hours
- What paperwork you get at the end
- Whether the whole system is included, or only the parts that are easy to reach
