Air handling unit cleaning in Hartley, Kent
Need AHU cleaning in Hartley? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- Coils clogged with dust and debris
- Air handling units with blocked filters
- Dust built up on fan impellers
The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Hartley, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us where we can park and unload
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system

About our AHU cleaning in Hartley
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with air handling units never cleaned inside and air handling units with blocked filters, across filter sections, internal panels and dampers and louvres.
Somewhere as small as Hartley, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Hartley
About 4.7 miles east of Hartley is Benenden Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. About 39 miles out from central London, Hartley is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
Classrooms and halls at schools such as High Weald Academy are easiest to work in when pupils are away.

How the job changes from site to site
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
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.

Common problems we fix in Hartley
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Look out for these warning signs:
- Units needing a clean before a new tenant or handover
- Dirty filters cutting the airflow
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
If you run a surgery, dental practice or care home near Hartley, clean ventilation matters as much to you as to a hospital like Benenden Hospital (about 4.7 miles east).

Why deal with it now?

Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Report water on the plant room floor
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
- Report musty smells from the vents straight away
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Hartley: your questions answered
Is Hartley within the area you cover?
Yes, we work in villages as well as towns, and Hartley is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you offer AHU cleaning in Hartley?
Yes. Our area runs across London and the South East, Hartley included. A fixed quote normally follows within one working day of the survey details.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
Do you need to switch the unit off?
Yes, for the time we’re working on it. Out-of-hours work is available to keep disruption down.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
