The process
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes from a few hours for a compact unit to a day or more for a large one. In a place like Botley, we fit the visit around your hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

About our AHU cleaning in Botley
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. Typical jobs include drain trays holding standing water and debris and leaves in the fresh air intake, across internal panels, heating and cooling coils and drain trays.
In a place like Botley, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
A written report with photos follows each visit, 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 staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
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.
What AHU cleaning looks like in Botley
Food Standards Agency data includes about 6 schools, colleges and universities and about 4 hotels and B&Bs within about 1.5 miles of central Botley. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Botley is about 55 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. Radcliffe Infirmary is the nearest hospital, about 1.8 miles east of Botley. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage a school such as Botley School, ventilation cleaning is best booked for the holidays.

What else we do in Botley
What AHU cleaning can’t fix
We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:
- Dirty ducts beyond the unit itself
- Building management system faults
- Faulty motors, drives or bearings
If you are not sure, just phone us on 0345 646 2711, or send details by email and we will give you a straight answer.
What we work on in Botley
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Filter sections
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Book the next check in line with the report
- Don’t ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
- Make sure the unit’s access doors open easily
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Common questions in Botley
Can you get to a site in Botley?
Yes, Botley is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Do you work overnight in Botley?
Yes, nights and weekends are routine for us. It means the site in Botley keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Where the site is and how we reach it
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Asking for a quote
To speed up the quote, send us:
- The paperwork from the last visit, if you have it
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, call us on 0345 646 2711, or email photos.
Managing agents and facilities teams in Botley
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
When to call us in Botley
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Most sites get in touch when they notice one of these:
- Condensate trays that won’t empty
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
Hospitals such as Radcliffe Infirmary (about 1.8 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Botley are no different.
