AHU Cleaning in Cadmore End
We cover Cadmore End for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
- Fan sections that haven’t been cleaned in years
What the work involves, part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
About our AHU cleaning in Cadmore End
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, internal panels and supply and extract fans, and common reasons people get in touch are fan sections that haven’t been cleaned in years and drain trays holding standing water.
Work in a small place like Cadmore End starts with agreeing access and timings.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Somewhere as small as Cadmore End, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Questions from Cadmore End
Do you cover smaller places like Cadmore End?
Yes. Villages and rural sites across the South East are part of our work, Cadmore End included. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work at weekends in Cadmore End?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Cadmore End needn’t be disturbed. When you call 0345 646 2711 or email us, mention when the site is quiet.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
How long does it take to clean an air handling unit?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, so call us on 0345 646 2711 or email us to talk it through.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What affects the quote in Cadmore End
The diagnosis comes before the price. We look at:
- The times the site is available
- How big the system is
- The condition of the system
- Whether several sites go on one quote
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 we start.
What we need to know
When you call or email, it’s useful to have:
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- The site address and the type of premises
- The paperwork from the last visit, if you have it
Want a quote for AHU cleaning? Please ring 0345 646 2711 or send us an email with a few details about the site. We will talk you through the work and give you a fixed quote before you commit to anything.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Cadmore End.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711, or send details by email.
Advice
What AHU cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
- Mechanical faults with motors, belts or bearings
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before you book.
Where we work
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Drain trays
- Internal panels
- Filter sections
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
