AHU cleaning for kitchens and businesses in Postling
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers heating and cooling coils, dampers and louvres and drain trays, and people most often call us about debris and leaves in the fresh air intake and dirty fans and fan housings.
Work in a small place like Postling starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Ventilation in Postling buildings
Royal Victoria Hospital is the nearest hospital, about 4.9 miles east of Postling. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. At about 57 miles from central London, Postling sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
If you manage a school such as Brockhill Park Performing Arts College, ventilation cleaning is best booked for the holidays.

What the work involves, part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. We agree a date with you, plan the drive to Postling and turn up when the site is quiet.
- 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
- Find the previous report, if there is one
- Move anything stored near the system
- Let us know when the site is closed or quiet
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or send us an email.

When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer.
What the work covers
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Filter sections
What we’re called out for in Postling
Whatever surrounds a building in Postling, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
- Air handling units never cleaned inside
Royal Victoria Hospital, about 4.9 miles east, is the nearest hospital to Postling, and healthcare sites of every size need their supply air kept clean.
Comparing quotes

- Whether the quote is based on a survey or pictures
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What hours they’ll be on site
Keeping the system healthy
After the visit, a few habits help the work last:
- Store the TR19 paperwork where auditors can find it
- Don’t store bins or materials near the intake
- Make sure the unit’s access doors open easily
- Stick to the filter change plan
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
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.

Why it’s worth doing now in Postling
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. It’s worth booking a check, because nobody sees inside a duct day to day.
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 play a part.

Postling: your questions answered
Can you come to Postling after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Postling needn’t be disturbed. Your opening times are the first thing we ask for.
Is Postling in your area for AHU cleaning?
Yes, we work in Postling and the places around it. To start, phone us on 0345 646 2711 or drop us a line with a few photos of the system.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
How long does it take to clean an air handling unit?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, so call 0345 646 2711 or drop us a line to talk it through.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
