AHU cleaning in Cole Henley
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers dampers and louvres, drain trays and supply and extract fans, and common reasons people get in touch are units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays.
Somewhere as small as Cole Henley, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.

What we’re called out for in Cole Henley
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Common reasons sites call us are:
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
Ventilation work in and around Cole Henley is risk-based: inspect, then clean what needs it.
Questions to ask before you book
- Proof of accreditation you can verify
- What happens if part of the system cannot be accessed
- What paperwork you get at the end
- Whether the quote is based on a survey or pictures
FAQs for Cole Henley
Will you come out to Cole Henley?
Yes. Cole Henley 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.
Do you offer AHU cleaning in Cole Henley?
Yes, Cole Henley is within the area we cover across London and the South East. To start, phone us on 0345 646 2711 or drop us a line with a few pictures of the system.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
What should I send you?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Between visits
Once we’ve finished, these simple steps help:
- Diary the inspection date recommended in the report
- Stick to the filter change plan
- Report stiff or damaged access doors
- Report musty smells from the vents right away
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
The process
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Cole Henley before we set off.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

Staff cleaning versus specialist work
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.
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, next to our reports.
How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- How easy every part is to reach
- Whether several sites go on one quote
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
Asking for a quote
Before you ask for a quote, gather:
- The site address and the type of premises
- Any previous report or certificate
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
