What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The times the site is available
- The condition of the system
- The number of sites or systems
- Site requirements such as sign-in and permits
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.
What to send for a quote
Before you ask for a quote, gather:
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- Wide pictures of the system and the area around it
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
AHU cleaning in Anna Valley, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers dampers and louvres, filter sections and internal panels, and the jobs we see most are air handling units never cleaned inside and debris and leaves in the fresh air intake.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. In a small place like Anna Valley, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Honest limits
It’s worth knowing the limits before booking:
- Problems with the unit’s controls or sensors
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think.
What the work covers
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Filter sections
- Heating and cooling coils
- Internal panels
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Report musty smells from the vents straight away
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
- Keep the area around the fresh air intake clear
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
What we do, step by step
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. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Anna Valley.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, ring 0345 646 2711, or send details by email.
