What the work involves, part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
AHU cleaning in Botley
Our AHU cleaning covers sites in Botley and the rest of Hampshire, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Common call-outs are for stale or musty smells from the ventilation and air handling units due a clean after building work, on supply and extract fans, filter sections and drain trays.
In a place like Botley, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
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 carry full insurance.

- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.

Advice
AHU cleaning around Botley
Food Standards Agency records list about 11 schools, colleges and universities and about 17 care, childcare and hospital premises registered as food businesses within roughly a mile and a half of the centre of Botley. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Botley, the closest hospital is Moorgreen Hospital, roughly 2.2 miles north-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Healthcare buildings such as Moorgreen Hospital, about 2.2 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Botley, yours matters too. If you run an office near Botley station, its supply ductwork can gather dust for years before anyone looks inside.

Aftercare tips
So the system stays in good health:
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Botley simpler. A planned visit to Botley fits your hours; an emergency does not.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.

Signs you need AHU cleaning in Botley
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
School buildings such as Botley Church of England Controlled Primary School are normally done in the holidays, so classrooms aren’t disturbed.

In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
