About our AHU cleaning in Pimlico
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We’re often asked to deal with dust-coated heating and cooling coils and rooms that smell stuffy when the system runs, on filter sections, internal panels and dampers and louvres.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Pimlico.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Look at the condensate drain whenever the unit is serviced
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

Signs you need AHU cleaning in Pimlico
Whatever surrounds a building in Pimlico, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
If you notice any of these, it’s worth a diagnosis:
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
- Units that have only ever had filter changes
- Dust built up on fan impellers
For workplaces around London Victoria station with mechanical ventilation, cleaning can be done in the evening or at weekends.
What to look for in a quote
- Whether they’re fully insured
- Whether the quote is based on a survey or pictures
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
AHU cleaning around Pimlico
Food Standards Agency data includes about 73 schools, colleges and universities, about 37 caring premises (care homes, nurseries and hospitals) and about 103 hotels, B&Bs and guest houses across Pimlico and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. London plant rooms are often on roofs or in basements reached through occupied floors. For Pimlico, the closest hospital is The Gordon Hospital, roughly under half a mile north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Wherever a school like Churchill Gardens Primary Academy has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run a surgery, dental practice or care home near Pimlico, clean ventilation matters as much to you as to a hospital like The Gordon Hospital (about under half a mile north-east).

What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Getting kit into a London building takes planning, so let us know where we can load and park in Pimlico.
- We survey the unit from photos 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 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 photos.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend

Common questions in Pimlico
Can ventilation in schools around Pimlico be cleaned out of term?
Yes, holiday work suits schools best. With about 73 schools and colleges on the FSA’s register within roughly a mile and a half of Pimlico, it pays to plan holiday dates ahead. Just call 0345 646 2711, or email photos with your term dates and we will plan around them.
Can the work in Pimlico be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Pimlico needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
