- Dirty filters cutting the airflow
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
How we handle AHU cleaning in Botolphs
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you have dust-coated heating and cooling coils and air handling units with blocked filters, we can help, from drain trays, heating and cooling coils and internal panels onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
What happens on the day
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We agree a date with you, plan the drive to Botolphs and turn up when the site is quiet.
- 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.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
When to call us in Botolphs
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Condensate trays that won’t empty
- Plant that needs cleaning after a refit
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
Healthcare buildings such as Southlands Hospital, about 3.3 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Botolphs, yours matters too.

What the work covers
- Heating and cooling coils
- Filter sections
- Drain trays
- Dampers and louvres
- Internal panels
- Supply and extract fans
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
- Don’t store bins or materials near the intake
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
