AHU cleaning in Monkwood, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers heating and cooling coils, drain trays and dampers and louvres, and people most often call us about fan sections that haven’t been cleaned in years and condensate trays that won’t empty.
For a building in or near Monkwood, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
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 half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Somewhere as small as Monkwood, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- 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 about permits to work or site inductions
- Move anything stored near the system
- Have your last certificate or report to hand

What else we do in Monkwood
When it’s something else
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Mechanical faults with motors, belts or bearings
- A system that is undersized for the building
- Building management system faults
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before you book.
What we work on in Monkwood
- Supply and extract fans
- Drain trays
- Filter sections
- Internal panels
- Dampers and louvres
- Heating and cooling coils
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Make sure condensate is draining away
- File each AHU report in the maintenance log
- Change filters on schedule and log each change
- Don’t store bins or materials near the intake
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Monkwood: your questions answered
Can the work in Monkwood be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Monkwood can fit around your hours. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Can you get to a site in Monkwood?
Yes, we work in villages as well as towns, and Monkwood is covered. A survey first, from photos or a visit, means we arrive with the right kit.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, including evenings or weekends.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

Questions to ask before booking
- Proof of insurance
- Proof of accreditation you can verify
- When the next visit should be, and why
- Whether the quote shows VAT
Why act early in Monkwood
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. With notice, the visit to Monkwood can be fitted around your bookings and events.
