AHU cleaning for kitchens and businesses in Portmore
Where a building in Portmore has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for plant that needs cleaning after a refit and intake sections clogged with outdoor debris, across dampers and louvres, filter sections and internal panels.
For a building in or near Portmore, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Portmore questions
Do you clean school ventilation in Portmore in the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Portmore. Just call us on 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you cover smaller places like Portmore?
Yes, we work in villages as well as towns, and Portmore is covered. Let us know about access, parking and anything unusual about getting there when you book.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Do you have insurance?
Yes. We’re fully insured, and the details are available on request.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
How long does it take to clean an air handling unit?
Expect it to take one overnight shift for many single units, with bigger plant phased. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. For a village or hamlet like Portmore, tell us about narrow lanes, gates and parking when you book.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
- Agree a time when the area can be out of use
Getting a quote
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.

When it’s something else
A few issues sit outside what this work can do:
- Controls and BMS settings that run the unit
- Dirty ducts beyond the unit itself
- A system that is undersized for the building
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
What the work covers
- Drain trays
- Heating and cooling coils

- Filter sections
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Whether several sites go on one quote
- The size of the system
- The condition of the system
- Access, including roofs, risers and ceiling voids
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before work begins.
AHU cleaning in Portmore: local notes
Food Standards Agency data includes about 7 schools, colleges and universities, about 4 caring premises (care homes, nurseries and hospitals) and about 4 hotels, B&Bs and guest houses within about 1.5 miles of central Portmore. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1 mile south-west of Portmore is Lymington New Forest Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Southlands School has ducted ventilation, a half-term visit keeps the work out of lesson time. Lymington New Forest Hospital, about 1 mile south-west, is the nearest hospital to Portmore, and healthcare sites of every size need their supply air kept clean.
Portmore is about 2 miles north-east of Lymington, in Hampshire. From the centre of Portmore to the outskirts, we cover AHU cleaning for every kind of premises, from a single unit to a large public building. Our area takes in 683 places across Hampshire, from busy centres to quieter spots. For sites nearby, see our Southampton page (11 miles or so).
Work in SO41 follows the same survey, fixed quote and written report as everywhere else we cover. That includes premises on Warborne Lane, Jordans Lane and Main Road and the roads around them.

Why deal with it now?
Stuffy rooms and stale smells in a building in Portmore can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Our emergency line runs 24/7, but a planned visit to Portmore is calmer for everyone.
What you pay depends on the size of the system, 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.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents straight away
- Watch for drips or damp patches near the plant
- Change filters on schedule and log each change
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
