Aircon coil replacement

Evaporator or condenser coil replacement, once we confirm the leak's in the coil and not a cheaper joint. We’ll assess first, then confirm whether this is the right scope before you book.

What coil replacement covers

The coil is where heat moves: the evaporator indoors, the condenser outdoors. When one corrodes or springs a pinhole, the system loses refrigerant no top-up will hold. We confirm the leak's in the coil, not a cheaper joint, before quoting a swap. Common situations where coil replacement fits:

  • Gas keeps running out and the leak's at the coil

    A pressure test traces the loss to the coil itself, not a joint or flare that could be resealed.

  • Visible corrosion or a pinhole on the fins

    Salt air and age eat through thin coil walls, especially on coastal or high-floor units.

  • The coil's beyond a clean

    Buildup cleans off; a holed or corroded coil doesn't. That's a replacement, not a chemical wash.

When coil replacement isn't suitable

A coil swap is a major repair. These point somewhere cheaper first.

  • The leak's at a joint or flare

    A reseal or flare repair is far cheaper than a coil. Leak detection locates the source first.

  • The coil's just dirty, not holed

    Buildup and mould clean off. Chemical servicing restores cooling without a swap.

  • The whole system's near end of life

    On an old unit, a new coil may not be worth it. We weigh it against a full replacement.

What you get

The leak confirmed at the coil before you spend on one.

  • Leak located, not guessed

    We pressure-test to confirm the coil's the source, so you're not paying for a coil that wasn't the problem.

  • Coil-vs-system math

    We weigh a new coil against replacing the unit, so an old system doesn't get an expensive coil it won't outlast.

  • Correct coil sourced

    Matched to the unit and refrigerant, then pressure-tested and recharged after fitting.

How a coil replacement works

No swapping a coil on a guess. From your first message to a system that holds, here is what happens.

  1. You message us

    Tell us the symptom: repeated gas loss, weak cooling, or visible corrosion on the coil.

  2. We assess on-site ($30)

    We pressure-test to confirm the leak's in the coil and not a joint, and check whether the system's worth a new coil. The $30 rules out work you don't need.

  3. We explain what we found

    Plain language: whether it's the coil, a cheaper joint, or an ageing system better replaced whole.

  4. We quote, you decide

    The coil, labour, and refrigerant, with the lead time if the part needs sourcing. Nothing goes ahead without your say.

  5. We replace and verify

    The $30 comes off the repair. We fit the coil, pressure-test, recharge, and confirm cooling holds before we leave.

What we check before quoting

A coil's an expensive part. We rule out the cheaper causes and weigh the system's age before quoting one.

  • Leak location

    Pressure testing confirms the coil's the source, not a flare joint, service valve, or pipe run.

  • Coil condition

    Corrosion, pinholes, and fin damage on the evaporator or condenser, and whether it's repairable or a swap.

  • Coil vs system

    Unit age and part cost weighed against a full replacement, so an old system isn't given a coil it won't outlast.

  • Part match

    The correct coil for the unit and refrigerant, with the sourcing lead time confirmed before scheduling.

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 labour warranty. If the same fault returns from the repair we did, we come back and the labour is on us, with no second diagnosis fee.

Parts

Parts follow whatever warranty the distributor sets for that component, so the term varies by part. We tell you the coverage before you approve the quote.

Documented coil cases

Real diagnosis work, not generic service claims. Open the case if the symptom looks familiar.

Frequently asked questions about aircon coil replacement in Singapore

How much does aircon coil replacement cost?
The coil itself is priced by brand, model, and whether it's the evaporator or condenser. Labour and refrigerant are on top. We confirm the coil's the actual fault before quoting, and the $30 visit is rebated if you proceed.
Should I replace the coil or the whole system?
On a newer unit, a coil is worth it. On an old system, the coil cost can approach a new install with warranty, in which case replacement is the better value. We lay out both before you decide.
Can a leaking coil be repaired instead of replaced?
Sometimes a single accessible pinhole can be repaired, but corrosion is rarely isolated, so a patched coil often leaks again nearby. Where a repair won't hold, replacement is the honest call. We tell you which this is.
How long does coil replacement take?
Usually 1 to 2 days including sourcing. The fitting itself is a half-day job, but we confirm the correct coil is available for your model before scheduling.
