About our AHU cleaning in Headley Down
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Typical jobs include dust built up on fan impellers and units that have only ever had filter changes, across dampers and louvres, drain trays and heating and cooling coils.
For a building near Headley Down, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
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.

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Diary the inspection date recommended in the report
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Your opening hours decide when we come to Headley Down, not ours.
- 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.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system

Advice
Staff cleaning versus 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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
When it’s something else
A few issues sit outside what this work can do:
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
- The supply and extract ducts, quoted separately
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
What the work covers
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Drain trays
For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Work can be phased by floor, building or site around the people who use them.
How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Your questions about AHU cleaning in Headley Down
Do you work in villages like Headley Down?
Yes, Headley Down is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can you come to Headley Down after we close?
Yes, we can come after you close and finish before you open. The work in Headley Down can fit around your hours. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

Can you set up regular visits?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
