About our AHU cleaning in Stubbings
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. Typical jobs include dust-coated heating and cooling coils and air handling units due a clean after building work, on filter sections, dampers and louvres and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

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. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Seeing the system in photos first means the trip to Stubbings can be planned properly.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Our emergency line runs 24/7, but a planned visit to Stubbings is calmer for everyone.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or email photos, and we will talk you through it.

Fixed quotes for AHU cleaning in Stubbings
A fixed price needs a few facts first. We look at:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Between visits
Simple habits between visits make a real difference. Our advice:
- Book the next check in line with the report
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

When to call us in Stubbings
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Signs it’s time to call us include:
- Air handling units never cleaned inside
- Condensate trays that will not empty
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
If you run a surgery, dental practice or care home near Stubbings, clean ventilation matters as much to you as to a hospital like St Mark's Hospital (about 1.4 miles east).

Your questions about AHU cleaning in Stubbings
Can the work in Stubbings be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Stubbings can fit around your hours. When you ring 0345 646 2711, or email photos, mention when the site is quiet.
Can a school’s ventilation in Stubbings be done out of term time?
Yes. The holidays are the usual time for school work. There are about 17 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Stubbings. You can call 0345 646 2711, or send details by email with the dates the site is empty.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How long does an AHU clean take?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.
How much notice do you need?
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.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
What staff can safely do
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. That’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

What else we do in Stubbings
What the work involves, part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
