In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
AHU cleaning in Penenden Heath
Where a building in Penenden Heath has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. We’re often asked to deal with dust built up on fan impellers and intake sections clogged with outdoor debris, across drain trays, supply and extract fans and heating and cooling coils.
Smaller buildings around Penenden Heath often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What happens on the day
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. In a smaller place like Penenden Heath, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive

Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Different parts, different methods
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.

Common questions in Penenden Heath
Do you cover smaller places like Penenden Heath?
Yes. Penenden Heath is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Penenden Heath?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
Will the ventilation be off while you clean?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.

Fixed quotes for AHU cleaning in Penenden Heath
We do not publish a price list, because sites vary so much. What we look at:
- A single visit or a regular plan
- The condition we find in the survey
- Working hours and out-of-hours timing
- Any permits to work or inductions
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What we need to know
We can often survey from photos. The most useful are:
- The site address and the type of premises
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Common problems we fix in Penenden Heath
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Keep an eye out for any of the following:
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
- Filters that are clogged or overdue
If you manage shops or offices close to Maidstone East station, a TR19® Air inspection shows whether the ductwork needs cleaning.
What your quote should include
- If they look at the system before pricing
- What paperwork you get at the end
- What hours they’ll be on site
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
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.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
