Air handling unit cleaning in South Moreton, Oxfordshire
Need AHU cleaning in South Moreton? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
Keeping the system healthy
To keep the system working properly between visits:
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Keep the certificate and photo report with the plant records
- Note any water around the unit or leaks below it
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.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning for kitchens and businesses in South Moreton
Where a building in South Moreton has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for dust built up on fan impellers and dirty coils holding back the airflow, on heating and cooling coils, drain trays and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What else we do in South Moreton
How the job changes from site to site
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
What we’re called out for in South Moreton
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Any of these means the system needs a check-up:
- Condensate trays that won’t empty
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Air handling units never cleaned inside
In South Moreton, we look inside the system before deciding what needs cleaning.
What to look for in a quote
- What insurance they carry
- If the quote is a fixed price or an estimate
- How they set the interval to the next visit
- When they can work, and whether that is outside your opening hours
How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to South Moreton.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
Ask for a quote
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will normally have a quote within one working day.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Questions from South Moreton
Is South Moreton in your area for AHU cleaning?
Yes. Our area runs across London and the South East, South Moreton included. Just ring 0345 646 2711 or send us an email with a few details of the site.
Can the work in South Moreton be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, for example new access panels.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Breakdowns that need a mechanical engineer
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly.
Parts of the system we cover
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Supply and extract fans
- Drain trays
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
