How we handle AHU cleaning in Lower Hardres
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. If you’re dealing with filters that are clogged or overdue and units that have only ever had filter changes, we can help, from filter sections, heating and cooling coils and supply and extract fans onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Between visits
To keep the system working properly between visits:
- Note any water around the unit or leaks below it
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.

What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- Whether we need access equipment or extra panels
- How big the system is
- Whether several sites go on one quote
- Travel, parking and unloading
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, ring 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
What we need to know
We can often survey from photos. The most useful are:
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
- A few general shots of the system
- The postcode and the type of business
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
How the visit works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Lower Hardres and turn up when the site is quiet.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system

Advice
Why act early in Lower Hardres
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. If the system at a site near Lower Hardres fails, there may be nowhere nearby to move to.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

FAQs for Lower Hardres
Is AHU cleaning available in Lower Hardres?
Yes, we work in Lower Hardres and the places around it. Get in touch with the details and we’ll arrange a survey.
Do you cover smaller places like Lower Hardres?
Yes. Lower Hardres is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
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 does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What we’re called out for in Lower Hardres
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
If you notice any of these, it’s worth a diagnosis:
- Blocked condensate drains and slimy trays
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
- Intake sections clogged with outdoor debris
Hospitals such as Kent and Canterbury Hospital (about 2.2 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Lower Hardres are no different.
