Looking for AHU cleaning in Ley Hill? We diagnose first, fix the price and book the work around your hours, then sign off with a report and photos.
- Units that have only ever had filter changes
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Photos of the system and how to reach it help us plan a visit to Ley Hill.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Related advice
AHU cleaning in Ley Hill, done properly
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have plant that needs cleaning after a refit and units that have only ever had filter changes, we can put it right, from dampers and louvres, drain trays and heating and cooling coils onwards.
Work in a small place like Ley Hill starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

How we price AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- Parking and loading at the site
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

- Where the plant sits or the system leaves the building, such as a roof or outside wall

Ley Hill questions
Do you work at weekends in Ley Hill?

Yes, we work in villages as well as towns, and Ley Hill is covered. The journey is planned ahead, so a few details about the route help.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.

Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.

What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Ley Hill simpler. With notice, the visit to Ley Hill can be fitted around your bookings and events.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.

What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Aftercare tips
Once we have finished, these simple steps help:
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
- Don’t ignore odours coming through the grilles
- Keep inspection doors on the unit in good order
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Common problems we fix in Ley Hill
It matters for two reasons: 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.
These are the problems we see most often:
- Air handling units with blocked filters
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
If you run a surgery, dental practice or care home near Ley Hill, clean ventilation matters as much to you as to a hospital like Amersham Hospital (about 3.8 miles south-west).
