AHU cleaning in Woodway, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you are dealing with air handling units never cleaned inside and coils clogged with dust and debris, we can put it right.
Somewhere as small as Woodway, ducted ventilation is typically 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. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Between visits
Aftercare is simple, and it makes the next visit easier:
- Change filters on schedule and log each change
- Report musty smells from the vents right away
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
We recommend when the unit should next be inspected or cleaned, based on what we found. 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, rather than waiting for a problem.
What AHU cleaning looks like in Woodway
About 49 miles out from central London, Woodway is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Wherever a school like Blewbury Endowed Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. An inspection comes first for any ventilation job around Woodway, so the cleaning matches what’s there.

What the work involves, part by part
Internal casing and panels

Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Woodway: your questions answered
Do you cover Woodway for AHU cleaning?
Yes, Woodway is covered. A fixed quote typically follows within one working day of the survey details.
Do you work overnight in Woodway?
Yes, evening, overnight and weekend work is normal for us. The work in Woodway can fit around your hours. Tell us your opening hours when you ask for a quote.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
What information do you need?
Where the site is, what it is and when it’s open, along with a few pictures and any previous 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. Large plant can be split over several shifts, so ring 0345 646 2711 or send us an email to talk it through.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Fixed quotes for AHU cleaning in Woodway
There’s no set price list, because sites vary so much. The quote depends on:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
- Site rules, permits and inductions
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What we need to know
To help us quote quickly, send us:
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
What a clean will not put right
Some problems need a different service or another trade:
- Building management system faults
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think.
What the work covers

How it works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further.

- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Agree a time when the area can be out of use

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, next to our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
