What FCU replacement covers
The FCU is the indoor fan coil unit, the part on your wall or ceiling. When it's beyond economical repair, a cracked casing, a failed coil and motor together, water damage, but the outdoor unit and piping are sound, replacing just the FCU is cheaper than a whole new system. Common situations where it fits:
The indoor unit's failed, the outdoor's fine
A dead or damaged FCU on a working condenser doesn't need a full system swap.
Several indoor parts have gone at once
When the coil, motor, and board all fail together, a new FCU often costs less than fixing each.
Physical or water damage to the indoor unit
A cracked casing, flood damage, or a seized unit past repair, with the rest of the system sound.
When FCU replacement isn't suitable
Replacing the indoor unit isn't always the right call. These point elsewhere first.
Only one component has failed
A single fault, a motor, board, or sensor, is a repair, not an FCU swap. Start with diagnosis.
The outdoor unit is also failing
If the condenser's near end of life too, weigh a full system replacement instead.
The unit's just dirty or smelly
Buildup and mould clean off. Servicing restores it without a new unit.
What you get
The indoor unit replaced without paying for a full system you don't need.
Repair-vs-replace-FCU math
We confirm the indoor unit's beyond economical repair before quoting a new one, so a fixable fault isn't oversold.
Your outdoor unit and piping reused
Sound condenser, copper, and drainage stay; only the indoor unit's swapped, where it makes sense.
Matched FCU fitted and commissioned
A new indoor unit matched to the outdoor unit and refrigerant, then vacuumed, charged, and tested.
What we check before quoting
Replacing the indoor unit only makes sense if the rest of the system's worth keeping. We confirm that first.
Indoor unit condition
Whether the FCU's repairable or beyond it: casing, coil, motor, board, and water damage.
Outdoor unit & piping
Whether the condenser, copper, and drainage are sound enough to reuse with a new indoor unit.
Refrigerant match
That the new FCU matches the existing refrigerant and outdoor unit, so the system runs as one.
Part match & lead time
The correct indoor unit for the system, with sourcing confirmed before scheduling.
We confirm the indoor unit is beyond economical repair and that the outdoor unit and piping are worth keeping before a new indoor unit is quoted. How a job runs, from first message to booking.
From our jobs
Photos our team took on jobs across Singapore.
Workmanship warranty
We stand behind the repair we carry out, and we are straight about the part of the cover we do not set ourselves.
Labour
30-day workmanship warranty. If the same fault returns from our repair, we come back and the labour is on us, with no second diagnostic visit fee.
Parts
Parts carry the distributor's warranty for that component, so the term varies by part. We tell you both terms before you approve the work.
Indoor unit case patterns
When the indoor unit itself is the fault rather than the circuit feeding it.
