The heart of your air conditioner is frequently referred to as the AC compressor. It facilitates the efficient absorption and release of heat by circulating refrigerant. Regardless of how you change the thermostat, your air conditioner won’t be able to cool effectively if the compressor breaks down. Early awareness of the signs of compressor failure may prevent you from experiencing unforeseen malfunctions and costly repairs.

In one of our earlier blogs, How to Solve Common Problems in Ac, we discussed simple troubleshooting steps you can try at home. But if the root cause lies in the compressor, DIY fixes usually won’t help you’ll need professional intervention.

Typical indicator of AC compressor issues

1. Instead of Cool Air
If your AC is blowing warm air, even with the settings correct, it could mean the compressor isn’t circulating refrigerant effectively.

2. Loud or Unusual Noises
Grinding, screeching, or rattling noises coming from the outdoor unit are classic signs of compressor trouble. These sounds usually indicate worn-out parts or internal damage.

3. Regular Tripping or Difficult Starting
A compressor that is malfunctioning frequently has trouble turning on. The compressor could be overburdening the electrical system if your air conditioner keeps tripping the circuit breaker.

4. Reduced Airflow
If the compressor cannot maintain proper pressure, airflow weakens. Even with clean filters and ducts, the cooling will feel insufficient.

5. Refrigerant Leaks or Ice Build-Up
Visible ice on coils or refrigerant leaks near the compressor unit indicate serious mechanical issues that need immediate repair.

Solutions for AC Compressor Issues

1. Professional Diagnosis
Since compressors involve refrigerant and electrical components, avoid DIY fixes. A certified AC technician will inspect wiring, refrigerant levels, and mechanical wear to determine the exact issue.

2. Timely Repairs vs. Replacement
Minor problems like capacitor replacement can save the compressor. However, if it’s completely burnt out, replacing the compressor or in older units, the entire AC may be more cost-effective.

3. Regular Maintenance
Routine servicing can prevent compressor failure. Cleaning coils, checking refrigerant pressure, and inspecting electrical connections extend the unit’s lifespan.

Just like routine washing machine repair in Kolkata helps prevent sudden breakdowns, your AC also benefits from scheduled maintenance. Preventive care saves both time and money while avoiding the stress of emergency repairs.

When to Call a Professional

If your AC is still blowing hot air, making unusual noises, or tripping the circuit breaker, don’t delay professional help. A trained technician can provide safe, long-lasting solutions something DIY checks can’t cover. Ignoring compressor issues not only reduces comfort but can also lead to complete system failure. Many professional AC repair technicians are available in Kolkata with proper setup their workshop. Many AC repair centers in Kolkata have many experienced AC repair technicians, so they can provide quick service for AC repairing service. But, it is very important to know that all experienced AC repair technicians have no sound knowledge in all parts of AC. So, try to find the genuine skilled technician for your AC repair.

Frequently Asked Questions

1. How long does an AC compressor last?
With proper maintenance, a compressor typically lasts 10–15 years.

2. Can I run my AC with a bad compressor?
No. Running it may further damage the unit and increase repair costs.

3. Why does my compressor keep tripping the breaker?
It may be overworking due to low refrigerant, dirty coils, or internal electrical faults.

4. How can I prevent compressor failure?
Schedule annual servicing, clean filters monthly, and keep the outdoor unit free from dust and debris.

5. Is replacing a compressor expensive?
Yes. In many cases, if the unit is old, replacing the entire AC is more cost-effective than replacing just the compressor.
