Fan Coil Unit Condensate Blockage explained
Clearance of blocked fan coil condensate systems — trays, traps, pipework and pumps — with the fall corrected so the blockage does not simply return. Every visit starts with a check of the surrounding system, because fan coil unit condensate blockage problems are frequently caused by something upstream — pressure, controls, water quality or an earlier installation shortcut. You get a plain explanation of what we found and what it will cost to put right.
- Blockage location and clearance
- Trap, tray and pipework flush
- Pump and float chamber clean
- Safety switch test and reset
- Pipework fall correction
- Anti-microbial dosing to prevent regrowth
- Drain flow test before leaving
Symptoms we get called to
The usual trigger for a call is a tray overflowing, a safety switch tripping the unit or water marking the ceiling. Other signs worth acting on early include unexplained noise, water where it should not be, pressure that will not hold, and temperatures that drift away from where they were set. Left alone these get more expensive, so an early diagnostic visit is almost always the cheaper route.
- Reported fault: a tray overflowing, a safety switch tripping the unit or water marking the ceiling
- Noise, vibration or unusual running behaviour
- Pressure loss, discharge or visible water
- Temperature or performance that has drifted over time
What the engineer checks on site
The engineer tests each element in turn rather than swapping parts hopefully. Findings are recorded, photographed where useful and sent to you afterwards, which matters for landlords, managing agents and anyone keeping compliance records for a building.

Fan Coil Unit Condensate Blockage across London
Customers usually call us about fan coil unit condensate blockage when they notice a tray overflowing, a safety switch tripping the unit or water marking the ceiling. Rather than guessing, the engineer works through the system in a fixed order, isolates the component at fault and shows you what has failed before anything is replaced. That approach keeps the first visit productive and means you are not paying for a second engineer to repeat the same tests a week later.
Fan Coil Unit Condensate Blockage sits within our fan coil unit services work. We service, repair, clean, commission and replace fan coil units in offices, hotels, apartment blocks and retail units — covering the chilled water and LTHW circuits, control valves, actuators, PICVs, condensate systems, fan motors, sensors and BMS interface as one system rather than as separate trades. Because we handle the surrounding system as well as the individual component, faults that cross between pumps, controls, valves and hot water get solved once instead of being passed between trades.
We work on equipment from Dunham Bush, Diffusion, Ability Projects, Daikin, Toshiba and other major manufacturers, and we carry the common service parts for these on the van. Where a specialist part has to be ordered, we tell you the lead time and the price on the day rather than leaving you waiting for a quote.
Coverage runs across Central, North, South, East and West London and out to the M25 — including Camden, Islington, Westminster, Chelsea, Hammersmith, Croydon, Bromley, Ealing, Barnet, Poplar and the surrounding Home Counties towns. Same-day attendance is normally available for urgent fan coil unit condensate blockage work, and out-of-hours visits can be arranged for commercial sites that cannot lose service during trading hours.
Landlords, letting agents and facilities managers use us for fan coil unit condensate blockage because the paperwork comes with the work: a written record of what was tested, photographs of the components we found at fault, the parts fitted and the readings taken at handover. That record goes straight into a property file or a planned maintenance schedule, and it gives you evidence if a tenant, an insurer or an inspector asks what has been done.
Booking fan coil unit condensate blockage is straightforward. Call 07427 826446 and describe what the system is doing, or request a visit online and we will confirm a slot the same day wherever the diary allows. There is no call-out fee on top of the hourly rate, parts are quoted before they are fitted, and all workmanship carries a 12-month guarantee. If we believe replacement is better value than repair we will say so, with prices for both, so the decision stays yours.
