Aircon compressor repair

We diagnose compressor faults before recommending replacement. Repair vs replace gets settled on-site. We’ll assess first, then confirm whether this is the right scope before you book.

What compressor repair covers

The compressor circulates refrigerant and is the single most expensive component, so a failed compressor isn't always the right diagnosis. We rule out refrigerant and electrical faults first, then test the compressor itself. Common situations where compressor work fits:

Unit runs but doesn't cool after basic causes are ruled out
If airflow and refrigerant check clear, the compressor circuit becomes a stronger suspect.
Breaker trips when the aircon starts
High starting current can come from the compressor, capacitor, relay, or wiring.
Outdoor unit is silent while the indoor unit runs
We need to test the compressor, contactor, capacitor, and outdoor supply before quoting any repair.

When compressor repair isn't suitable

Compressor replacement is expensive. If the fault isn't confirmed, start with a diagnostic visit and rule out the common lookalikes.

Low refrigerant or active leak
Pressure, leak, and top-up calls should come before blaming the compressor.
Dirty outdoor coil or failed outdoor fan
Poor heat rejection mimics compressor trouble. Fix that first.
Old system with major repair risk
If the unit's near end of life, inspection should weigh repair cost against replacement before any compressor quote.

What you get

A confirmed diagnosis before you commit to the most expensive aircon component repair.

Cheaper causes ruled out
We check refrigerant, airflow, capacitor, relay, and supply before quoting compressor repair.
Repair economics explained
You get a repair-versus-replacement view before spending on an older or high-risk system.
Approval before parts
We don't order or fit a compressor until the fault, part match, and price are agreed.

What we check before quoting

We work through the causes that mimic compressor failure before quoting a major component repair.

Refrigerant and airflow
We check low gas, leaks, dirty coils, and airflow restrictions before testing the compressor itself.
Capacitor, relay, and supply
We test start components and electrical supply, because they cause trips and no-start symptoms that look like compressor failure.
Compressor windings
Resistance and ground checks tell us whether the motor winding is open, shorted, or within range.
Repair vs replacement
We weigh unit age, part cost, and warranty value before recommending a compressor quote.

Refrigerant, airflow, the capacitor, the relay and the supply are ruled out before the compressor windings are tested, and a repaired system runs a full cycle before we leave. How a job runs, from first message to booking.

Brand-specific compressor repair

Each brand page lists the models we see, that brand’s fault codes, parts lead times and when replacement makes more sense.

From the field

An outdoor unit opened up for diagnosis, testing the compressor circuit before quoting.

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.

Compressor case patterns

Diagnosis-led case notes, not generic service claims. Open the case if the symptom looks familiar.

Frequently asked questions about aircon compressor repair in Singapore

How much does compressor repair cost?

A capacitor replacement is a fraction of a full compressor swap. The compressor itself is priced by brand, model, and system type (single-split vs multi-split). We diagnose first and quote before any parts are ordered.

Should I repair or replace an old unit with compressor failure?

Replacement makes sense when the compressor cost approaches the price of a new unit with warranty. On a 10-year-old system, that's often the case. We give you an honest assessment, and if replacement is the better call, we'll say so.

Can you repair all compressor types?

Yes. We handle rotary and scroll compressors found in residential split and multi-split systems. That covers the majority of residential installations in Singapore.

How long does compressor replacement take?

Typically 1 to 2 days including sourcing. The replacement itself is a half-day job, but we need to confirm part availability for your specific model before scheduling. We'll tell you the lead time once the fault and part match are confirmed.
