How we handle AHU cleaning in Adeyfield
We clean air handling units for buildings in Adeyfield and across Hertfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with dust-coated heating and cooling coils and debris and leaves in the fresh air intake, we can help, from heating and cooling coils, dampers and louvres and supply and extract fans onwards.
In a place like Adeyfield, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- What state the system is in
- Travel, parking and unloading
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
What to send for a quote:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.
What we’re called out for in Adeyfield
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Most sites get in touch after spotting something like this:
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
- Filters that are clogged or overdue
- Dirty fans and fan housings
Hospitals such as Hemel Hempstead Hospital (about 0.9 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Adeyfield are no different.
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- What records you’ll receive afterwards
- What insurance they carry
- Whether the price is fixed
Why act early in Adeyfield
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. You choose the date of a planned visit, and a breakdown never asks.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or email us for straight advice and a fixed quote.

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Getting to the system matters more than parking in a place like Adeyfield, so let us know how to reach it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
How to prepare
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
- 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: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Can ventilation in schools around Adeyfield be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 29 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Adeyfield. Send us your term dates when you call 0345 646 2711 or drop us a line, and we will fit the work in.

Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
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.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

Yes. Full insurance covers our work, and we’ve been trading since 2009.
Between visits
Good habits slow the build-up between visits. Our tips:
- Keep filter changes on time and recorded
- Make sure condensate is draining away
- File each AHU report in the maintenance log
- Make sure the unit’s access doors open easily
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
