Greensted Green AHU cleaning
AHU cleaning for Greensted Green, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Dirty filters cutting the airflow
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
What the work involves, part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
About our AHU cleaning in Greensted Green
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for dust built up on fan impellers and coils clogged with dust and debris, across supply and extract fans, dampers and louvres and heating and cooling coils.
For a building in or near Greensted Green, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Do you need AHU cleaning in Greensted Green?
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Clients typically contact us after spotting one of these:
- Filters that are clogged or overdue
- Dirty fans and fan housings
- Drain trays holding standing water
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Greensted Green, clean ventilation matters as much to you as to a hospital like St. Margaret's Hospital (about 3.5 miles west).
Before you book anyone
- Whether they’re fully insured
- If they look at the system before pricing
- Whether the price is fixed
- What hours they’ll be on site
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
- Store the TR19 paperwork where auditors can find it
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

What happens on the day
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. Rural roads and tight entrances are worth telling us about before a visit to Greensted Green.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in

How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.

How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Whether we need access equipment or extra panels
- How many systems or sites are involved
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Why act early in Greensted Green
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Out of sight is the usual reason a rural system goes too long without attention.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or send us an email, and we’ll explain what it covers.
