AHU cleaning in City of London: how it works
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. Typical jobs include blocked condensate drains and slimy trays and dirty fans and fan housings, on dampers and louvres, filter sections and supply and extract fans.
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes one overnight shift for many single units, with bigger plant phased.
- 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.
- We close up the unit and send the certificate and before and after photos.
What you’ll pay
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, ring 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

Where we work in City of London
Buildings across City of London range from large sites with several air handling units to small units in a roof space. Every system has filters, coils, drain trays and ductwork to keep clean.
From central London kitchens to coastal hotels and country pubs, London and the South East have every kind of site. Wherever the site is in City of London, the work is done to the same TR19® standard.
City of London: If you run an office near London Cannon Street station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near City of London, clean ventilation matters as much to you as to a hospital like London Bridge Hospital (about 0.6 miles south-east).
Different parts, different methods
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Managing agents and facilities teams in City of London
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Facilities teams in offices, schools and healthcare sites book us too across City of London. Larger estates can be phased building by building around the people who use them.
What affects the quote in City of London
You’ll get a fixed price before work begins. It takes into account:
- How easy every part is to reach
- Site requirements such as sign-in and permits
- What state the system is in
- Where the site is and how we reach it
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What we need to know
When you call or email, it’s useful to have:
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- Where the site is and what kind of site it is
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 any work starts.
Signs you need AHU cleaning
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Signs it’s time to call us include:
- Filters that are clogged or overdue
- Odours coming through the supply air
- Dust built up on fan impellers
- Units that have only ever had filter changes
Honest limits
It’s worth knowing the limits before booking:
- Building management system faults
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
Questions from City of London
Do you need to switch the unit off?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Are you insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
How long does an AHU clean take?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
