AHU cleaning in Nursling
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have blocked condensate drains and slimy trays and rooms that smell stuffy when the system runs, we can put it right.
For a building near Nursling, 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 are fully insured.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Evenings, weekends or a closed day all work for a site in a place like Nursling.
- 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 photos are taken and the certificate issued.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet
- Tell us about site rules, permits or sign-in

Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
When to call us in Nursling
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.
If you notice any of these, it’s worth a diagnosis:
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
- Drain trays holding standing water
Classrooms and halls at schools such as Nursling Church of England Primary School are easiest to work in when pupils are away.
Before you book anyone
- How they set the interval to the next visit
- If they look at the system before pricing
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What insurance they carry
What the work involves, part by part
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Watch for drips or damp patches near the plant
- Keep the area around the fresh air intake clear
- Diary the inspection date recommended in the report
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. When a site near Nursling shuts unexpectedly, the people who rely on it notice at once.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711, or send details by email for straight advice and a fixed quote.

Nursling questions
Do you work overnight in Nursling?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Nursling needn’t be disturbed. Just phone us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Can you get to a site in Nursling?
Yes. Nursling is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What do you need from me for a quote?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
