About our AHU cleaning in Meonstoke
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. We are often asked to deal with units needing a clean before a new tenant or handover and condensate trays that won’t empty, on internal panels, drain trays and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.

Questions from Meonstoke
Can you work in Meonstoke outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Meonstoke needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Can ventilation in schools around Meonstoke be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Meonstoke. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
How long will the unit be out of action?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Pictures of the system and its access let us plan the work in Meonstoke before we set off.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Honest limits
We’d rather tell you now than book work that won’t help, so here are the limits:
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
- Airflow problems caused by the system’s design
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think before booking.

Signs you need AHU cleaning in Meonstoke
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Look out for any of the following:
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
- Units needing a clean before a new tenant or handover
- Fan sections that haven’t been cleaned in years
For buildings in and around Meonstoke, TR19® Air cleaning starts with an inspection.

Why it’s worth doing now in Meonstoke
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. It’s worth booking a check, because nobody sees inside a duct day to day.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or email us, and we’ll explain what it covers.

What affects the cost of AHU cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- How big the system is
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Any permits to work or inductions
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
You do not need the technical terms. It helps if you can send:
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Looking after it afterwards
After the visit, a few habits help the work last:
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
- Diary the inspection date recommended in the report
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
