Air handling unit cleaning in Ewhurst Green, Surrey

- Intake sections clogged with outdoor debris
How we handle AHU cleaning in Ewhurst Green
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. We are often asked to deal with condensate trays that won’t empty and units needing a clean before a new tenant or handover, on internal panels, drain trays and heating and cooling coils.
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 report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Looking after it afterwards
Results last longer with the right care. We suggest:
- Change filters on schedule and log each change
- Look at the condensate drain whenever the unit is serviced
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
The process
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 it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Ewhurst Green is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
- Find the previous report, if there is one
Getting a quote
To get a fixed quote, ring 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You’ll usually have a quote within one working day.
Related advice
What we’re called out for in Ewhurst Green
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Keep an eye out for any of the following:
- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
- Filters that are clogged or overdue
- Odours coming through the supply air
School buildings such as Ewhurst CofE Aided Infant School are typically done in the holidays, so classrooms are not disturbed.
