Hampshire · Air handling unit cleaning
Air handling unit cleaning in Mockbeggar, Hampshire
We cover Mockbeggar for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports as standard.
- Air handling units with blocked filters
- Air handling units due a clean after building work
- Dirty coils holding back the airflow
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
About our AHU cleaning in Mockbeggar
We clean air handling units for buildings in Mockbeggar and across Hampshire, 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 internal panels, heating and cooling coils and drain trays, and the jobs we see most are units that have only ever had filter changes and plant that needs cleaning after a refit.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Mockbeggar questions
Do you work overnight in Mockbeggar?
Yes, evening, overnight and weekend work is normal for us. It means the site in Mockbeggar keeps running as normal. Your opening times are the first thing we ask for.
Is Mockbeggar in your area for AHU cleaning?
Yes, Mockbeggar is within the area we cover across London and the South East. A fixed quote usually follows within one working day of the survey details.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Do you need AHU cleaning in Mockbeggar?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
These are the problems we see most often:
- Rooms that smell stuffy when the system runs
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
In Mockbeggar, we look inside the system before deciding what needs cleaning.
What to look for in a quote
- What happens if part of the system cannot be accessed
- Whether a written report and photos are included
- Whether VAT is included
- Whether the quote is based on a survey or photos
Keeping the system healthy
Results last longer with the right care. We suggest:
- Store the TR19 paperwork where auditors can find it
- Stick to the filter change plan
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. Somewhere like Mockbeggar, lanes, gates and parking are worth mentioning in advance.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend

Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
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.
What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- A system that is undersized for the building
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711 or email us and we will say what we think.
