AHU cleaning in Shellingford, done properly
Coils are where a lot of the dirt ends up. 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 are not flattened. Common call-outs are for coils clogged with dust and debris and leaves and litter drawn into the unit, on drain trays, supply and extract fans and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Healthcare buildings such as Longworth Hospital, about 2.3 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Shellingford, yours matters too.

Different parts, different methods
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Do you need AHU cleaning in Shellingford?
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
Wherever a school like Shellingford Church of England (Voluntary Aided) School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before you book
- Whether the whole system is included, or only the parts that are easy to reach
- How areas they cannot reach will be recorded
- Whether the figure could change on the day
- What hours they’ll be on site
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What else we do in Shellingford
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Shellingford questions
Do you work overnight in Shellingford?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can you get to a site in Shellingford?
Yes, Shellingford is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What do you do with what you remove?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Fixed quotes for AHU cleaning in Shellingford
Before we fix a price, we need to know a few things. We look at:
- Site rules, permits and inductions
- A single visit or a regular plan
- How big the system is
- The number of sites or systems
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
What we need to know
To speed up the quote, send us:
- The site address and the type of premises
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then phone us on 0345 646 2711, or email photos.
What your team can do, and what needs us
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.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
What happens on the day
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Shellingford, 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.
- The unit is shut down with your site team and the area 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.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
