AHU cleaning for kitchens and businesses in Abbots Worthy
Our AHU cleaning covers sites in Abbots Worthy and the rest of Hampshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers internal panels, filter sections and supply and extract fans, and common reasons people get in touch are stale or musty smells from the ventilation and coils clogged with dust and debris.
Work in a small place like Abbots Worthy starts with agreeing access and timings.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Any permits to work or inductions
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- One-off work versus a regular cycle
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711, or email photos.

Ventilation in Abbots Worthy buildings

Signs you need AHU cleaning in Abbots Worthy

- Debris and leaves in the fresh air intake
- Coils clogged with dust and debris
- Units needing a clean before a new tenant or handover
- Air handling units with blocked filters
Healthcare buildings such as St John's Rooms And Chapel, about 2.3 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Abbots Worthy, yours matters too.

What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Abbots Worthy run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

What else we do in Abbots Worthy
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
