How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, 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. If the van will struggle with a lane or gateway near Lower Heyford, let us know and we will plan around 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.
- After photos are taken and the certificate issued.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or email us.
Advice
About our AHU cleaning in Lower Heyford
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for rooms that smell stuffy when the system runs and coils clogged with dust and debris, across filter sections, internal panels and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Fixed quotes for AHU cleaning in Lower Heyford
You’ll get a fixed price before work begins. It takes into account:
- How many systems or sites are involved
- The times the site is available
- A single visit or a regular plan
- Whether we need access equipment or extra panels
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
Asking for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Why deal with it now?
Stuffy rooms and stale smells in a building in Lower Heyford can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Systems in rural buildings are often out of sight and out of mind.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.

Honest limits
Before you book, it helps to know what’s not included:
- Dirty ducts beyond the unit itself
- Building management system faults
- Damaged coils beyond cleaning
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Supply and extract fans
- Drain trays
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
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.

Common questions in Lower Heyford
Will you come out to Lower Heyford?
Yes, we work in villages as well as towns, and Lower Heyford is covered. Just mention lanes, gates or anything else about the site when you book.
Is AHU cleaning available in Lower Heyford?
Yes. Our area runs across London and the South East, Lower Heyford included. Get in touch with the details and we will arrange a survey.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
Managing agents and facilities teams in Lower Heyford
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Between visits
Results last longer with the right care. We suggest:
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
- Keep the certificate and photo report with the plant records
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
