How we handle AHU cleaning in Poynders End
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you have debris and leaves in the fresh air intake and dust built up on fan impellers, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces 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 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.

What AHU cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly before you book.
Where we work
- Internal panels
- Supply and extract fans
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Drain trays
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Poynders End, let us know and we will plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards

How we price AHU cleaning
We don’t publish a price list, because sites vary so much. The quote depends on:
- What state the system is in
- The number of sites or systems
- Parking and loading at the site
- A single visit or a regular plan
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

When you call or email, these details help:
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep filter changes on time and recorded
- Keep the area around the fresh air intake clear
- Watch for drips or damp patches near the plant
- Don’t ignore odours coming through the grilles
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Different parts, different methods
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
