AHU cleaning for kitchens and businesses in East Marden
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with filters that are clogged or overdue and units needing a clean before a new tenant or handover, we can help, from internal panels, dampers and louvres and supply and extract fans onwards.
Somewhere as small as East Marden, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How it works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like East Marden, tell us about narrow lanes, gates and parking when you book.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Agree a time when the area can be out of use
- Let us know about parking and loading
- Clear loose items from the work area
How to get a quote
Photos are enough for some jobs, while others need a look on site. 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 any work starts.
Related advice
Do you need AHU cleaning in East Marden?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Signs it’s time to call us include:
- Leaves and litter drawn into the unit
- Condensate trays that won’t empty
- Air handling units due a clean after building work
- Air handling units with blocked filters
Whether the building is in East Marden itself or nearby, filters, coils, drain trays and ducts are all part of the work.
Questions to ask before booking
- Whether the whole system is included, or only the parts that are easy to reach
- Proof of accreditation you can verify
- How areas they cannot reach will be recorded
- Whether the quote is based on a survey or pictures
Different parts, different methods
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Between visits
Once we have finished, these simple steps help:
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Flag stale or damp smells in the supply air
- Change filters on schedule and log each change
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Honest limits
Before you book, it helps to know what’s not included:
- Damaged coils beyond cleaning
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly.

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- Travel, parking and unloading
- How easy every part is to reach
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Wide pictures of the system and the area around it
- Problems your staff have spotted
- When the site is open and when it’s quiet
- Your last certificate, test record or report
The quickest way to a quote is to send pictures: 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.
