AHU cleaning in Forstal, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you have dust built up on fan impellers and drain trays holding standing water, we can help.
For a building in or near Forstal, 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.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

The process
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Forstal, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Find the previous report, if there is one
- Clear loose items from the work area
- Agree a time when the area can be out of use
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Keep filter changes on time and recorded
- Check the drain tray is emptying during routine visits
- Store the TR19 paperwork where auditors can find it
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Why deal with it now?
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. Out of sight is the usual reason a rural system goes too long without attention.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Part by part
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.

- Whether we need access equipment or extra panels
- What state the system is in

- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- A few general shots of the system
- Detail shots of panels, filters and grilles
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
