AHU cleaning for kitchens and businesses in Rowly
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers drain trays, dampers and louvres and supply and extract fans, and common reasons people get in touch are dust built up on fan impellers and odours coming through the supply air.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Aftercare tips
How long the results last depends on use and care. We suggest:
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
- Keep filter changes on time and recorded
- File each AHU report in the maintenance log
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.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

What do you need from me for a quote?
A short description and a few pictures, with the address and opening hours. If we need more, we will ask.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Are you fully insured?
Yes. We’re fully insured, and we can share the details when you need them.
What we do, step by step
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Rowly, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet

What a clean will not put right
In fairness, there are a few things this work will not fix:
- Building management system faults
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.

- Supply and extract fans
- Filter sections
- Dampers and louvres
- Drain trays
- Internal panels
- Heating and cooling coils
What affects the quote in Rowly
Sites vary more than people expect. The main factors:
- Where the site is and how we reach it
- The condition we find in the survey
- How big the system is
- Access, including roofs, risers and ceiling voids
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, call 0345 646 2711 or drop us a line.
