The compressor is the heart of your air conditioner — when it won’t start, you get no cooling. ROMA Heating & Cooling diagnoses and repairs compressor-start problems across Greater Vancouver.
Why an AC compressor won’t start
A compressor that hums, clicks or stays silent usually points to one of these:
- A failed start/run capacitor (a very common, repairable cause)
- A bad contactor not sending power to the compressor
- An overheated compressor on thermal overload
- Low refrigerant or pressure-switch lockout
- Wiring, control-board or thermostat faults
- A seized compressor (the most serious case)
How ROMA diagnoses it
We test the capacitor, contactor, electrical supply and pressures to find exactly why the compressor isn’t starting, then quote the repair up front. Many compressor-start issues are an inexpensive capacitor or contactor — not a full compressor replacement.
Repair vs replace
If it’s a capacitor or contactor, repair is quick and affordable. If the compressor itself has failed on an older system, we’ll quote both a compressor replacement and a new high-efficiency system so you can choose.

Frequently Asked Questions
Is a humming AC compressor that won’t start serious?
Often it’s a failed capacitor — a common, affordable fix. But don’t keep cycling it; that can overheat the compressor.
How much does an AC capacitor cost to replace?
It’s one of the more affordable AC repairs. We give you a flat-rate quote up front after diagnosing.
Can a bad compressor be repaired?
Sometimes the start components are the issue, not the compressor. If the compressor itself has failed, replacement of the unit is often the better value.
