Stalisfield AHU cleaning
Our technicians work in Stalisfield on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports on every job.
- Dirty filters cutting the airflow
- Coils clogged with dust and debris
- Condensate trays that won’t empty
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Stalisfield, the date and timings are agreed with you well before the day.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Let us know about permits to work or site inductions

AHU cleaning in Stalisfield, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include dust built up on fan impellers and dirty coils holding back the airflow, across drain trays, internal panels and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A fault that closes a site in a village like Stalisfield affects everyone who depends on it.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.

Do you need AHU cleaning in Stalisfield?
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Most sites get in touch when they notice one of these:
- Stale or musty smells from the ventilation
- Condensate trays that won’t empty
- Dirty coils holding back the airflow
- Air handling units due a clean after building work
Around Stalisfield, an air handling unit’s drain tray is checked for standing water as a matter of course.

Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report water on the plant room floor
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
- Keep the area around the fresh air intake clear
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Stalisfield: your questions answered
Can you work in Stalisfield outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Stalisfield needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Is Stalisfield within the area you cover?
Yes, we work in villages as well as towns, and Stalisfield is covered. Photos of the system and directions to the site help us plan the visit.
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.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, give us a ring on 0345 646 2711 or send us an email with the site type, opening hours and a few photos.
Do you need to switch the unit off?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply give us a ring on 0345 646 2711 or use the quote form.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
