How we handle AHU cleaning in Hardwick
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. We’re often asked to deal with leaves and litter drawn into the unit and dirty fans and fan housings, across supply and extract fans, filter sections and heating and cooling coils.
Work in a small place like Hardwick starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
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.

Why act early in Hardwick
If people in a building in Hardwick complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Systems in rural buildings are often out of sight and out of mind.
Putting the work off seldom saves money. 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 drop us a line and we will give you an honest view and a fixed quote.
Why us?
- Full insurance on every job
- Every job surveyed first
- Work around your opening hours, with 24/7 emergency cover
- Accredited under CHAS and SafeContractor, with ISO 9001

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. In a small place like Hardwick, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a shutdown window that suits the building.
- 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.
Getting ready for the visit
- Tell us where we can park and unload
- Make sure someone can let us in and lock up afterwards
- Mention any locked doors, roof access or ceiling voids

Advice
Common problems we fix in Hardwick
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Clients normally contact us after spotting one of these:
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Dirty fans and fan housings
- Dirty coils holding back the airflow
Every job around Hardwick ends with a record of what was cleaned and what was found.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Report musty smells from the vents right away
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
- Book the next check in line with the report
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
What a clean will not put right
It’s worth knowing the limits before booking:
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
- Damaged coils beyond cleaning
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think before booking.

Your questions about AHU cleaning in Hardwick
Is Hardwick within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Hardwick included. Just mention lanes, gates or anything else about the site when you book.
Do you clean school ventilation in Hardwick in the holidays?
Yes, out-of-term visits are normal for schools. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hardwick. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
