What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
How we handle AHU cleaning in Wadesmill
If the units serving a building in Wadesmill have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you’re dealing with air handling units never cleaned inside and drain trays holding standing water, we can help, from filter sections, internal panels and dampers and louvres onwards.
Work in a small place like Wadesmill starts with agreeing access and timings.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. A quick note on how to find the site and where to park makes a visit to Wadesmill run smoothly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand

What affects the quote in Wadesmill
Your quote is based on your site. We take into account:
- The condition of the system
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- The number of sites or systems
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.
Helping us quote
What to send for a quote:
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.
Aftercare tips
Results last longer with the right care. We suggest:
- Report stiff or damaged access doors
- Report water on the plant room floor
- Report musty smells from the vents straight away
- Book the next check in line with the report
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Your questions about AHU cleaning in Wadesmill
Can the work in Wadesmill be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Wadesmill needn’t be disturbed. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can you get to a site in Wadesmill?
Yes, we work in villages as well as towns, and Wadesmill is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
How long does an AHU clean take?
The work takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, and you can phone us on 0345 646 2711 or use the quote form to plan it.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711 or send us an email.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Building management system faults
- Dirty ducts beyond the unit itself
- A system that is undersized for the building
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
