Questions from Duton Hill
Can you do AHU cleaning in Duton Hill?
Yes, we work in Duton Hill and the places around it. Get in touch with the details and we’ll arrange a survey.
Can you work in Duton Hill outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Duton Hill keeps running as normal. When you give us a ring on 0345 646 2711 or email us, mention when the site is quiet.
Where does the waste go?
We take it away when we go. During the work, it’s contained so the area stays clean.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
About our AHU cleaning in Duton Hill
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. Typical jobs include rooms that smell stuffy when the system runs and plant that needs cleaning after a refit, across drain trays, filter sections and heating and cooling coils.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Do you need AHU cleaning in Duton Hill?
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Any of these means the system needs a check-up:
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Air handling units with blocked filters
- Condensate trays that will not empty
If you manage a school such as Putteridge High School, ventilation cleaning is best booked for the holidays.

How it works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Rural roads and tight entrances are worth telling us about before a visit to Duton Hill.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
Getting a quote
We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.

When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Breakdowns that need a mechanical engineer
- Building management system faults
- A system that’s undersized for the building
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly before booking.
What we work on in Duton Hill
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Drain trays
- Dampers and louvres
- Filter sections
Leave it or put it right?
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. A planned visit to Duton Hill is easier to arrange than an emergency callout.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Make sure condensate is draining away
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
