What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A few photos of the system help us make the most of a visit to a place like Otterbourne.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Let us know when the site is closed or quiet

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
How we handle AHU cleaning in Otterbourne
Coils are where a lot of the dirt ends up. 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. The work covers internal panels, dampers and louvres and heating and cooling coils, and common reasons people get in touch are drain trays holding standing water and intake sections clogged with outdoor debris.
For a building in or near Otterbourne, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Ventilation in Otterbourne buildings
Food Standards Agency records list about 8 care, childcare and hospital premises registered as food businesses in Otterbourne and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. For Otterbourne, the closest hospital is Royal Hampshire County Hospital, roughly 3.7 miles north. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
School buildings such as Otterbourne Church of England Primary School are typically done in the holidays, so classrooms are not disturbed.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Stick to the filter change plan
- Diary the inspection date recommended in the report
- Don’t ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
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.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
FAQs for Otterbourne
Do you do school ventilation cleaning in Otterbourne in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Otterbourne. Just phone us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Will you come out to Otterbourne?
Yes. Villages and rural sites across the South East are part of our work, Otterbourne included. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What information do you need?
A short description and a few photos, with the address and opening hours. If we need more, we’ll ask.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Managing agents and facilities teams in Otterbourne
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Fixed quotes for AHU cleaning in Otterbourne
You’ll get a fixed price before we start. It’s based on:
- What state the system is in
- Whether we need access equipment or extra panels
- How big the system is
- The times the site is available
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- The times we could work without disrupting the site
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, call us on 0345 646 2711, or send details by email.

Common problems we fix in Otterbourne
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Keep an eye out for these warning signs:
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Drain trays holding standing water
Hospitals such as Royal Hampshire County Hospital (about 3.7 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Otterbourne are no different.

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Equipment tucked in a roof space or outbuilding near Otterbourne rarely gets looked at unless someone books it.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
