What the work involves, part by part
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
AHU cleaning in Heath End
If the units serving a building in Heath End have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers filter sections, supply and extract fans and internal panels, and people most often call us about dust built up on fan impellers and dirty coils holding back the airflow.
Work in a small place like Heath End starts with agreeing access and timings.
The paperwork matters as much as the work. You get a written report with pictures after each 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 to hand when an insurer or inspector asks.

For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, and that takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Heath End run smoothly.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
Getting a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. If the system at a site near Heath End fails, there may be nowhere nearby to move to.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.

Common problems we fix in Heath End
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Signs it’s time to call us include:
- Units needing a clean before a new tenant or handover
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
- Stale or musty smells from the ventilation
Fleet Community Hospital, about 4.4 miles north-west, is the nearest hospital to Heath End, and healthcare sites of every size need their supply air kept clean.
Before you book anyone
- How areas they can’t reach will be recorded
- How VAT is shown on the quote
- What hours they’ll be on site
- How they set the interval to the next visit
What AHU cleaning cannot fix
We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:
- Building management system faults
- The supply and extract ducts, quoted separately
- Faulty motors, drives or bearings
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think before you book.
What the work covers
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Drain trays
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Do not store bins or materials near the intake
- Note any water around the unit or leaks below it
- Make sure condensate is draining away
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
