Essex · Air handling unit cleaning
AHU Cleaning in Layer Marney
For air handling unit cleaning in Layer Marney, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
- Coils clogged with dust and debris
What happens if it’s left?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. It’s worth booking a check, because nobody sees inside a duct day to day.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

AHU cleaning in Layer Marney
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers dampers and louvres, filter sections and heating and cooling coils, and the jobs we see most are intake sections clogged with outdoor debris and filters that are clogged or overdue.
Somewhere as small as Layer Marney, ducted ventilation is usually 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.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When something else is needed
AHU cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly before booking.
Parts of the system we cover

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We take into account:
- The scale of the work
- Where the site is and how we reach it
- A single visit or a regular plan
- How easy every part is to reach
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
Asking for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- When the site is open and when it’s quiet
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Managing agents and facilities teams in Layer Marney
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Common problems we fix in Layer Marney
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Most sites get in touch after spotting something like this:
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
- Condensate trays that will not empty
For schools like Thurstable School, the holidays are the usual time to inspect and clean ventilation.

Common questions in Layer Marney
Can you work in Layer Marney outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Layer Marney keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you offer AHU cleaning in Layer Marney?
Yes, Layer Marney is covered. A fixed quote typically follows within one working day of the survey details.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What if parts of the system cannot be reached?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or drop us a line.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.
How long does it take to clean an air handling unit?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Can you quote from pictures?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Pictures of the system and its access let us plan the work in Layer Marney before we set off.

- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
