AHU cleaning in Ascott d'Oyley, done properly
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers heating and cooling coils, internal panels and drain trays, and people most often call us about odours coming through the supply air and plant that has been serviced but not cleaned.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What else we do in Ascott d'Oyley
What we’re called out for in Ascott d'Oyley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Keep an eye out for these warning signs:
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
Ventilation work in and around Ascott d'Oyley is risk-based: inspect, then clean what needs it.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Between visits
Once we’ve finished, these simple steps help:
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents straight away
- Report stiff or damaged access doors
- Make sure condensate is draining away
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What the work involves, part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.

What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
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.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Ascott d'Oyley.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down
