AHU cleaning in Abinger
Our AHU cleans for sites in Abinger cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers filter sections, heating and cooling coils and supply and extract fans, and people most often call us about dirty coils holding back the airflow and filters that are clogged or overdue.
Somewhere as small as Abinger, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The paperwork matters as much as the work. Each visit is written up with pictures, 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 ready for an insurer, fire officer or EHO.

- Dirty ducts beyond the unit itself

Fixed quotes for AHU cleaning in Abinger
You will get a fixed price before any work starts. It takes into account:
- Any permits to work or inductions
- How big the system is
- The number of sites or systems
- Working hours and out-of-hours timing
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711, or send details by email, and we’ll talk you through it.
What we need to know
We can often survey from photos. Try to include:
- The postcode and the type of business
- Wide pictures of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks

Why deal with it now?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. In a place like Abinger, ductwork and fans are easy to forget until something goes wrong.
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 not sure what’s needed, phone us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Clear leaves and litter away from the intake
- Stick to the filter change plan
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Abinger is set by you, and the travel is our side of the planning.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one

Advice
Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
What we’re called out for in Abinger
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Abinger, that is air they breathe for hours at a time.
What we’re most often called out for:
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
School buildings such as Belmont Prep School are usually done in the holidays, so classrooms are not disturbed.
Questions to ask before booking
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
- Exactly which parts of the system are covered
- Proof of accreditation you can verify
