AHU cleaning in East Horndon, done properly
We clean air handling units for buildings in East Horndon and across Essex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers filter sections, internal panels and heating and cooling coils, and common reasons people get in touch are plant that has been serviced but not cleaned and condensate trays that won’t empty.
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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

Fixed quotes for AHU cleaning in East Horndon
The diagnosis comes before the price. We look at:
- How many systems or sites are involved
- What state the system is in
- Any permits to work or inductions
- Access, including roofs, risers and ceiling voids
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
What we need to know
We can often survey from pictures. The most useful are:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
- Any previous report or certificate
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 photos, get a survey first. Either way, you get a fixed price before work begins.
Why it’s worth doing now in East Horndon
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Our emergency line runs 24/7, but a planned visit to East Horndon is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

Between visits
Simple habits between visits make a real difference. We recommend:
- Plan the next inspection before the last report gets filed away
- Note any water around the unit or leaks below it
- Report musty smells from the vents right away
- Check the drain tray is emptying during routine visits
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
