AHU cleaning in Headley, done properly
A cooling coil drips condensate into a tray that should drain away. 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. If you are dealing with plant that has been serviced but not cleaned and leaves and litter drawn into the unit, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How we price AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Where the site is and how we reach it
- Whether it’s a one-off visit or part of a schedule
- How easy every part is to reach
- The number of sites or systems
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.
Asking for a quote
There’s no need for technical detail. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- Any previous report or certificate
For a fixed quote, ring 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
Headley buildings and their air
There are about 3 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within roughly a mile and a half of the centre of Headley.

Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

Do you need AHU cleaning in Headley?
Whatever surrounds a building in Headley, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Signs it’s time to call us include:
- Air handling units never cleaned inside
- Air handling units due a clean after building work
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
School buildings such as St Andrew's Catholic School are typically done in the holidays, so classrooms are not disturbed.
What your quote should include
- What records you’ll receive afterwards
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the work can be done while the site is closed
- Whether the quote shows VAT
Why act early in Headley
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a small place like Headley, a system that fails can take a site out of use.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or email us, and we will explain what it covers.

What a clean will not put right
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
- Faulty motors, drives or bearings
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly.
What we work on in Headley
- Heating and cooling coils
- Dampers and louvres
- Internal panels
- Filter sections
- Supply and extract fans
- Drain trays
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Headley, let us know and we will plan around it.
- We survey the unit from photos 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, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Your questions about AHU cleaning in Headley
Do you do school ventilation cleaning in Headley in the summer holidays?
Yes. The holidays are the usual time for school work. Around Headley, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Can you come to Headley after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Headley keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Do you work in Headley?
Yes. Headley is part of the area we cover, as part of our area across London and the South East.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Can you price the work without visiting?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we will say so.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. 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. Reaching it takes a specialist with the right equipment.
