Kings Hill AHU cleaning
AHU cleaning for Kings Hill, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Dust-coated heating and cooling coils
- Units that have only ever had filter changes
- Condensate trays that will not empty
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Evenings, weekends or a closed day all work for a site in a place like Kings Hill.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Move anything stored near the system
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet

Photos are enough for some jobs, while others need a look on site. 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 work begins.

AHU cleaning in Kings Hill, done properly
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for filters that are clogged or overdue and units that have only ever had filter changes, across filter sections, drain trays and supply and extract fans.
Visits to a place like Kings Hill are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What else we do in Kings Hill
What we are called out for in Kings Hill
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Signs it’s time to call us include:
- Drain trays holding standing water
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
- Dust-coated heating and cooling coils
Healthcare ventilation, from large hospitals like Maidstone Hospital (about 3.4 miles east) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- Whether they’re fully insured
- What records you’ll receive afterwards
Why act early in Kings Hill
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A visit arranged in advance is far less disruptive than a callout on a busy day.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
What you get with us
- CHAS, SafeContractor and ISO 9001
- Every visit written up, with pictures
- Full insurance on every job
- Ventilation hygiene specialists since 2009

What affects the cost of AHU cleaning
We do not publish a price list, because no two systems are the same. The quote depends on:
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What we need to know
When you contact us, it’s useful to have:
- Wide pictures of the system and the area around it
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or email us.
Between visits
To keep the system working properly between visits:
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
- Report stiff or damaged access doors
- Stick to the filter change plan
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
AHU cleaning around Kings Hill
There are about 8 schools, colleges and universities and about 3 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Kings Hill, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Kings Hill is about 27 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. Kings Hill’s nearest hospital, Maidstone Hospital, is about 3.4 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Kings Hill School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Kings Hill is about 5 miles west of Maidstone, in Kent. Sites in Kings Hill get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Across Kent, we cover 922 places, and Kings Hill is one of them.

Questions from Kings Hill
Will you come out to Kings Hill?
Yes. Villages and rural sites across the South East are part of our work, Kings Hill included. The journey is planned ahead, so a few details about the route help.
Can you come to Kings Hill after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Kings Hill needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Are you insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Will the ventilation be off while you clean?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
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. At the end, the area is cleaned down.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
Honest limits
Some problems need a different service or another trade:
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
