AHU cleaning for kitchens and businesses in Doddinghurst
If the units serving a building in Doddinghurst have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you are dealing with units that have only ever had filter changes and leaves and litter drawn into the unit, we can help, from dampers and louvres, heating and cooling coils and filter sections onwards.
Somewhere as small as Doddinghurst, ducted ventilation is normally 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.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

AHU cleaning in Doddinghurst: local notes
Food Standards Agency records list about 5 care, childcare and hospital premises registered as food businesses within 1.5 miles or so of the middle of Doddinghurst. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Doddinghurst is about 21 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. Brentwood Community Hospital is the nearest hospital, about 3.1 miles south of Doddinghurst. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Doddinghurst, clean ventilation matters as much to you as to a hospital like Brentwood Community Hospital (about 3.1 miles south).

How it works
The visit has three parts: 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. The middle part takes longest, and that takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Doddinghurst, the date and timings are agreed with you well before the day.
- 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.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
Advice
Honest limits
A few issues sit outside what this work can do:
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
- Problems with the unit’s controls or sensors
If in doubt, call 0345 646 2711 or email us and we will say what we think before booking.
Where we work
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Internal panels
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- The number of sites or systems
- One-off work versus a regular cycle
- What state the system is in
- The size of the system
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before we start.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles

Do you need AHU cleaning in Doddinghurst?
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Look out for any of the following:
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
- Condensate trays that will not empty
- Intake sections clogged with outdoor debris
For schools like Doddinghurst Infant School, the holidays are the usual time to inspect and clean ventilation.
