AHU cleaning in Chartridge, done properly
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have odours coming through the supply air and dirty coils holding back the airflow, we can help, from internal panels, supply and extract fans and dampers and louvres onwards.
Work in a small place like Chartridge starts with agreeing access and timings.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common questions in Chartridge
Do you cover smaller places like Chartridge?
Yes, Chartridge is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you do school ventilation cleaning in Chartridge in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Chartridge. Booking early in the term gives the best choice of holiday dates.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes one overnight shift for many single units, with bigger plant phased. A few pictures of the system help us make the most of a visit to a place like Chartridge.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
- Let us know when the site is closed or quiet

Signs you need AHU cleaning in Chartridge
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
The symptoms we’re asked about most are:
- Odours coming through the supply air
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
Healthcare buildings such as Chiltern Hospital, about 3.1 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Chartridge, yours matters too.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Report stiff or damaged access doors
- Do not store bins or materials near the intake
- Store the TR19 paperwork where auditors can find it
- Watch for drips or damp patches near the plant
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
What a clean won’t put right
AHU cleaning can’t fix everything, and we will tell you before any work starts. It won’t put right:
- Coils that are corroded or leaking and need replacing
- Building management system faults
- Mechanical faults with motors, belts or bearings
If in doubt, call 0345 646 2711 or use the quote form and we’ll say what we think.

Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send 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.
Why act early in Chartridge
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. In a small place like Chartridge, a system that fails can take a site out of use.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before we start.
