Busy, occupied buildings like these are where clean supply air matters most. The nearest hospital to Hartley is Darent Valley Hospital, about 4 miles north-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. About 19 miles out from central London, Hartley is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
For workplaces around Longfield station with mechanical ventilation, cleaning can be done in the evening or at weekends. For schools like Hartley Primary Academy, the holidays are the usual time to inspect and clean ventilation.

How we handle AHU cleaning in Hartley
Where a building in Hartley has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have debris and leaves in the fresh air intake and units that have only ever had filter changes, we can help, from filter sections, supply and extract fans and drain trays onwards.
In a smaller place like Hartley, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Managing agents and facilities teams in Hartley
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Your questions about AHU cleaning in Hartley
Can you come to Hartley after we close?
Yes, nights and weekends are routine for us. That way a site in Hartley doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you work in villages like Hartley?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you need to switch the unit off?
Yes, for the time we’re working on it. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, including evenings or weekends.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Parking and loading at the site
- Site rules, permits and inductions
- The scale of the work
- What state the system is in
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What we need to know
To speed up the quote, please include:
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call us on 0345 646 2711, or send details by email.

What else we do in Hartley
What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Because the survey comes first, a visit to Hartley can normally be finished without a second trip.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
- Move anything stored near the system
How to get a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
Related advice
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Hartley simpler. A quieter site near Hartley still needs its system looked after.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.

When to call us in Hartley
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
What we are most often called out for:
- Filters that are clogged or overdue
- Air handling units never cleaned inside
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
Hospitals such as Darent Valley Hospital (about 4 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Hartley are no different.
Before you book anyone
- Whether the whole system is included, or only the parts that are easy to reach
- When the next visit should be, and why
- Which accreditations they hold, and whether you can check them
- Whether VAT is included
Looking after it afterwards
To keep the system working properly between visits:
- Make sure the unit’s access doors open easily
- Diary the inspection date recommended in the report
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
