Why it’s worth doing now in Great Parndon
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. It’s better to plan the work at a site near Great Parndon than wait for a failure.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.

AHU cleaning for kitchens and businesses in Great Parndon
Drain trays under cooling coils are meant to empty. 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. Common call-outs are for dust-coated heating and cooling coils and dirty filters cutting the airflow, on dampers and louvres, supply and extract fans and heating and cooling coils.
Visits to a place like Great Parndon are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When something else is needed
In fairness, there are a few things this work will not fix:
- The supply and extract ducts, quoted separately
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly.
What the work covers
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Internal panels
Looking after it afterwards
Once we have finished, these simple steps help:
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
- Flag stale or damp smells in the supply air
- Keep filter changes on time and recorded
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Any permits to work or inductions
- Parking and loading at the site
- The times the site is available
- The size of the system
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What we need to know
When you contact us, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
FAQs for Great Parndon
Do you clean school ventilation in Great Parndon in the holidays?
Yes, holiday work suits schools best. Around Great Parndon, the Food Standards Agency lists about 22 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711 or drop us a line, and we will fit the work in.
Can you get to a site in Great Parndon?
Yes, Great Parndon is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What does TR19 mean?
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.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Can you quote from photos?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Tell us when your site near Great Parndon is quiet and the visit will be booked for then.
- 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, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
How to get a quote
To get a fixed quote, ring 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Advice
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
