AHU cleaning in Asheldham
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. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers internal panels, heating and cooling coils and supply and extract fans, and the jobs we see most are dirty coils holding back the airflow and units needing a clean before a new tenant or handover.
In a village or hamlet like Asheldham, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

When to call us in Asheldham
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
It’s time to book a visit if you see:
- Stale or musty smells from the ventilation
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
- Units needing a clean before a new tenant or handover
Ventilation work in and around Asheldham is risk-based: inspect, then clean what needs it.

What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
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’s our job.
Asheldham buildings and their air
Food Standards Agency data includes about 3 hospitals, care homes and childcare premises within 1.5 miles or so of the middle of Asheldham. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Asheldham, about 43 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible.
Around Asheldham, an air handling unit’s drain tray is checked for standing water as a matter of course.

For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
How it works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. In a small place like Asheldham, the journey is planned ahead and the visit arranged around the site’s hours.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- 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.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms

Related advice
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Make sure the unit’s access doors open easily
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- The scale of the work
- The times the site is available
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- A few general shots of the system
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Questions from Asheldham
Will you come out to Asheldham?
Yes, we work in villages as well as towns, and Asheldham is covered. Photos of the system and directions to the site help us plan the visit.
Can you do AHU cleaning in Asheldham?
Yes, Asheldham is within the area we cover across London and the South East. Get in touch with the details and we’ll arrange a survey.
How long does an AHU clean take?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, out of hours if needed.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Can you quote from photos?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Part by part
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
