AHU cleaning for kitchens and businesses in Boarhunt
We clean air handling units for buildings in Boarhunt and across Hampshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers supply and extract fans, dampers and louvres and filter sections, and the jobs we see most are fan sections that haven’t been cleaned in years and air handling units with blocked filters.
Somewhere as small as Boarhunt, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- File each AHU report in the maintenance log
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Your questions about AHU cleaning in Boarhunt
Can a school’s ventilation in Boarhunt be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Boarhunt. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
Is Boarhunt within the area you cover?
Yes. Boarhunt is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll usually reply within one working day.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711 or send us an email.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Common problems we fix in Boarhunt
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
If you notice any of these, it’s worth a diagnosis:
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
If you manage a school such as Cams Hill School, ventilation cleaning is best booked for the holidays.
Comparing quotes

Leave it or put it right?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. If the system at a site near Boarhunt fails, there may be nowhere nearby to move to.
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.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Boarhunt and across Hampshire. Work can be phased by floor, building or site around the people who use them.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
What affects the cost of AHU cleaning
You’ll get a fixed price before any work starts. It’s based on:
- The condition we find in the survey
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Getting a quote does not take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
