How we handle AHU cleaning in Ashurst
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers filter sections, internal panels and drain trays, and people most often call us about condensate trays that won’t empty and dirty fans and fan housings.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What we’re called out for in Ashurst
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.

- Coils clogged with dust and debris
- Air handling units due a clean after building work
- Condensate trays that will not empty

Looking after it afterwards
Results last longer with the right care. We suggest:
- Look at the condensate drain whenever the unit is serviced
- Don’t ignore odours coming through the grilles
- Keep inspection doors on the unit in good order
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
What a clean won’t put right
AHU cleaning can’t fix everything, and we’d rather say so up front. It will not put right:
- The supply and extract ducts, quoted separately
- Problems with the unit’s controls or sensors
- Mechanical faults with motors, belts or bearings
If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think before you book.

How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Ashurst, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
Ask for a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711, or email photos.

What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to Ashurst is calmer for everyone.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

What affects the cost of AHU cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- Any permits to work or inductions
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Wide pictures of the system and the area around it
- Any previous report or certificate
For AHU cleaning in Ashurst, ring 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote normally follows within one working day.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
