AHU cleaning in Waltham Chase, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. Common call-outs are for dirty filters cutting the airflow and drain trays holding standing water, on supply and extract fans, internal panels and dampers and louvres.
Somewhere as small as Waltham Chase, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What happens if it’s left?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Planning a trip to Waltham Chase ahead is easier for everyone than a rushed one.

How much does AHU cleaning cost in Waltham Chase?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Can you quote from photos?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Signs you need AHU cleaning in Waltham Chase
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Most sites get in touch when they notice something like this:
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
- Plant that needs cleaning after a refit
- Condensate trays that won’t empty
Classrooms and halls at schools such as St John the Baptist Church of England Primary School are easiest to work in when pupils are away.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
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 will take a look and give you a fixed quote.
How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Waltham Chase run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet

- Ventilation that was badly designed in the first place
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Check the drain tray is emptying during routine visits
- Diary the inspection date recommended in the report
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
