Kent · Air handling unit cleaning
Air handling unit cleaning in Lewson Street, Kent
AHU cleaning for Lewson Street, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Stale or musty smells from the ventilation
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
How we handle AHU cleaning in Lewson Street
A cooling coil drips condensate into a tray that should drain away. 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 have dirty fans and fan housings and dust-coated heating and cooling coils, we can put it right, from filter sections, internal panels and dampers and louvres onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Your questions about AHU cleaning in Lewson Street
Can a school’s ventilation in Lewson Street be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Lewson Street. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Do you work at weekends in Lewson Street?
Yes, we can come after you close and finish before you open. That way a site in Lewson Street doesn’t have to lose a day’s trading. When you call 0345 646 2711, or email photos, mention when the site is quiet.
How much does AHU cleaning cost in Lewson Street?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711, or send details by email with the site type, opening hours and a few photos.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Can you quote from pictures?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
Why act early in Lewson Street
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. It’s simpler to plan the work at Lewson Street now than to arrange it in a hurry later.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Looking after it afterwards
Once we’ve finished, these simple steps help:
- Note any water around the unit or leaks below it
- Store the TR19 paperwork where auditors can find it
- Make sure condensate is draining away
- Book the next check in line with the report
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
