AC Compressor Not Working: Repair vs Replace (Kadapa)
If a technician told you the compressor is dead and quoted ₹10,000+, slow down. In 4 out of 5 cases we inspect, the compressor is fine and the actual fault is a ₹600 capacitor or a ₹1,500 contactor. Here is exactly how to tell the difference, and what to do if it really is the compressor.
Symptoms: is the compressor actually the problem?
Signs that suggest compressor failure:
- Outdoor fan spins normally but no cooling at all (no hum, no click from compressor body)
- Loud humming for a few seconds then thermal trip clicks in
- Visible oil leak around the compressor body
- Compressor casing extremely hot to touch (carefully) within minutes of running
Signs that point to capacitor or contactor (cheap fix):
- Fan won't start either, both stay silent
- Compressor hums but doesn't engage, capacitor swap fixes it
- Burnt smell near the electrical panel in the outdoor unit
- Intermittent operation, works one day, fails the next
The right diagnosis order (insist on this)
- Multimeter test on the capacitor (5 minutes)
- Visual + continuity test on the contactor (5 minutes)
- Voltage check at the compressor terminals while running
- Insulation resistance test on compressor windings (megger)
- Only after all 4 pass should you accept a compressor replacement quote
Repair costs by fault
| Fault | Cost in Kadapa |
|---|---|
| Capacitor replacement | ₹600 to ₹1,200 |
| Contactor / relay replacement | ₹700 to ₹1,500 |
| Overload protector reset / swap | ₹300 to ₹700 |
| Compressor terminal cleanup + wiring | ₹500 to ₹900 |
| Full compressor replacement (1.5 ton) | ₹7,500 to ₹10,500 |
Repair or buy a new AC?
Repair the compressor if: AC is under 7 years old, uses R32 or R410A gas, otherwise works well, and you got the original quote in writing with warranty.
Buy new if: AC is 10+ years old, uses R22 gas (being phased out), already had multiple repairs, or the compressor cost is more than 40% of a new 5-star inverter AC price.
A new 1.5 ton 5-star inverter AC in Kadapa costs ₹32,000 to ₹45,000 and pays back through electricity savings in 3 to 4 years.
Why compressors fail in Kadapa specifically
- Voltage drops below 180V on hot summer evenings overload the motor
- Annual coil cleaning skipped, so heat rejection drops and compressor overheats
- Slow refrigerant leak ignored, so compressor runs without cooling oil circulation
- Outdoor unit installed against a wall with poor airflow, traps heat

Frequently Asked Questions
How do I know if the compressor itself is dead vs just a small fault?+
Most cases of 'compressor not working' are actually a failed capacitor (₹600 to ₹1,200), a burnt contactor (₹700 to ₹1,500), or a tripped overload protector (free reset). A genuinely dead compressor (winding failure, mechanical seizure) is rare. Demand a multimeter test before agreeing to compressor replacement.
How much does AC compressor replacement cost in Kadapa?+
1 ton AC: ₹6,000 to ₹8,000. 1.5 ton AC: ₹7,500 to ₹10,500. 2 ton AC: ₹9,500 to ₹12,500. This includes the new compressor, gas, brazing, vacuum and 6 month warranty on the compressor itself.
Should I replace the compressor or buy a new AC?+
Rule of thumb: if your AC is under 7 years old and otherwise in good condition, replace the compressor. If it is 10+ years old (R22 gas, non-inverter), spend on a new 5-star inverter AC instead. Payback on power savings is usually 3 years.
What's the warranty on a replaced compressor?+
Genuine OEM compressors come with 6 months to 1 year warranty on parts. We give 6 months on the compressor plus 30 days on the labour. Avoid 'second-hand' or 'refurbished' compressors offered cheap, they fail within months.
Why did my compressor fail in the first place?+
Top 3 reasons in Kadapa: (1) voltage fluctuations without a stabilizer, (2) low refrigerant causing the compressor to overheat, (3) skipped servicing meaning the condenser is choked and the compressor overworked. Fix the root cause or the new compressor will die too.
