- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
- Dirty filters cutting the airflow
Common problems we fix in Camden Town
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Air handling units never cleaned inside
- Leaves and litter drawn into the unit
- Dirty coils holding back the airflow
- Condensate trays that won’t empty
Wherever a school like Our Lady Roman Catholic Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before you book
- What’s included in the scope, part by part
- Whether they recommend a next date
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the figure could change on the day
AHU cleaning in Camden Town, done properly
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for air handling units with blocked filters and fan sections that haven’t been cleaned in years, across supply and extract fans, internal panels and heating and cooling coils.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Camden Town, dust and debris build up in the units and ductwork over time.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Once we have finished, these simple steps help:
- Change filters on schedule and log each change
- Plan the next inspection before the last report gets filed away
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes one overnight shift for many single units, with bigger plant phased. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Camden Town.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
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 pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Common questions in Camden Town
Do you work at weekends in Camden Town?
Yes, evening, overnight and weekend work is normal for us. That way a site in Camden Town doesn’t have to lose a day’s trading. Just call us on 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Can ventilation in schools around Camden Town be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 83 schools, colleges and universities with registered kitchens within about a mile and a half of Camden Town. Tell us your holiday dates and we will book the visit for when the site is empty.
How much does AHU cleaning cost in Camden Town?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, typically ready within one working day.
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 we will suggest an interval after the first clean.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.

Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.

What else we do in Camden Town
Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Shared walls, risers and roofs mean a problem at one London site seldom stays put.

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
