AHU cleaning for kitchens and businesses in Buntingford
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, filter sections and internal panels, and the jobs we see most are filters that are clogged or overdue and dirty coils holding back the airflow.
Visits to a place like Buntingford are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Common questions in Buntingford
Can you work in Buntingford outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Buntingford does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Will you come out to Buntingford?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How long does it take to clean an air handling unit?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, and you can call 0345 646 2711 or email us to plan it.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. A site near Buntingford that has to close at short notice is hard to cover for.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Other services in Buntingford
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
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. Leave those to us.
When to call us in Buntingford
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Most sites get in touch after spotting one of these:
- Condensate trays that will not empty
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
Classrooms and halls at schools such as Millfield First and Nursery School are easiest to work in when pupils are away.
Questions to ask before booking
- Whether a written report and pictures are included
- How VAT is shown on the quote
- How they set the interval to the next visit
- If the quote is a fixed price or an estimate
What affects the quote in Buntingford
The diagnosis comes before the price. We look at:
- How easy every part is to reach
- The scale of the work
- One-off work versus a regular cycle
- The number of sites or systems
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.
Helping us quote
What to send for a quote:
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or use the quote form.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What happens on the day
We turn up 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 before any work starts, and floors and nearby surfaces are sheeted. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. Tell us when your site near Buntingford is quiet and the visit will be booked for then.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Move anything stored near the system
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
How to get a quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
