What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- The size of the system
- Whether several sites go on one quote
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Asking for a quote
Before you ask for a quote, gather:
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
AHU cleaning in Stokenchurch
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for air handling units with blocked filters and blocked condensate drains and slimy trays, on filter sections, heating and cooling coils and supply and extract fans.
In a smaller place like Stokenchurch, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. A site near Stokenchurch typically has room to park, so the questions are about access to the system and your hours.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in
Get a fixed quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Flag stale or damp smells in the supply air
- Store the TR19 paperwork where auditors can find it
- Stick to the filter change plan
- Note any water around the unit or leaks below it
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.

Why act early in Stokenchurch
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. Dealing with it early keeps the clean straightforward. Light use slows the build-up but does not stop it.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
