How we handle AHU cleaning in East Hendred
Our AHU cleans for sites in East Hendred cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. We’re often asked to deal with intake sections clogged with outdoor debris and units that have only ever had filter changes, across heating and cooling coils, drain trays and internal panels.
For a building in or near East Hendred, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in East Hendred knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- A TR19® certificate and photo report follow the clean.

Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. It’s worth booking a check, because nobody sees inside a duct day to day.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Stick to the filter change plan
- Report stiff or damaged access doors
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Common questions in East Hendred
Do you offer AHU cleaning in East Hendred?
Yes, East Hendred is within the area we cover across London and the South East. You can give us a ring on 0345 646 2711 or send us an email and let us know what needs doing.
Is East Hendred within the area you cover?
Yes, we work in villages as well as towns, and East Hendred is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Can you price the work without visiting?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Honest limits
Some problems need a different service or another trade:
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before booking.

Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. 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. Reaching it takes a specialist with the right equipment.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- The scale of the work
- The condition of the system
- Site requirements such as sign-in and permits
- Whether we need access equipment or extra panels
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
Asking for a quote
When you contact us, these details help:
- Wide photos of the system and the area around it
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
