Troubleshoot Your Aircon: 8 Common Reasons Why Your AC Won’t Turn On

Is your air conditioning system in Red Deer, Lacombe, Sylvan Lake, AB, and surrounding areas, failing to start up despite your best efforts? Don’t sweat it! Bruin’s Plumbing & Heating, Ltd. has compiled a list of the most common culprits behind a non-responsive AC unit. By following these troubleshooting steps, you’ll be well-equipped to identify the issue and determine if you can fix it yourself or if it’s time to call in the professionals. Let’s explore the eight common reasons why your AC won’t turn on:

1. Power Supply Issues

• Check the power source: Ensure that your AC unit is receiving power by checking the circuit breaker and verifying that it hasn’t tripped.
• Examine the power cord: Inspect the power cord for any signs of damage or loose connections. If you notice any issues, replace the cord immediately.

2. Thermostat Malfunction

• Set the thermostat correctly: Make sure your thermostat is set to “cool,” and the desired temperature is lower than the current room temperature.
• Replace batteries: If your thermostat uses batteries, replace them to ensure proper functionality.

3. Clogged Air Filter

• Locate and inspect the air filter: A clogged air filter can restrict airflow and cause your AC system to shut down. Check the filter for dirt, dust, and debris.
• Clean or replace the filter: If the air filter is dirty, clean it if it’s reusable or replace it with a new one. Regular filter maintenance is essential for optimal AC performance.

4. Frozen Evaporator Coils

• Check for ice buildup: If your AC unit has ice on the evaporator coils, it can hinder proper cooling and prevent the system from turning on.
• Thaw the coils: Switch off the AC and let the coils thaw completely. Once thawed, clean any residual water and inspect for any underlying issues that may have caused the freezing.

5. Faulty Contactor

• Inspect the contactor: The contractor is responsible for powering the compressor. Check for signs of wear, damage, or corrosion.
• Replace the contactor: If the contactor appears faulty, it’s best to have it replaced by a professional to avoid any electrical hazards.

6. Malfunctioning Capacitor

• Identify the capacitors: Your AC system may have both a start capacitor and a run capacitor. Inspect them for any bulging, leaking, or other signs of damage.
• Consult a professional: Capacitor replacement should be handled by a qualified technician due to the potential risks associated with electrical components.

7. Refrigerant Leak

• Look for refrigerant leaks: Low refrigerant levels can prevent your AC from turning on. If you notice oily spots or refrigerant leakage around the unit, contact a professional immediately.
• Professional repair: Refrigerant leaks require expert attention, as handling refrigerant can be hazardous. Our team is trained to handle such repairs safely and efficiently.

8. Compressor Problems

• Listen for unusual sounds: If your compressor is making grinding or humming noises, it could indicate a problem.
• Call a professional: Compressor issues typically require specialized knowledge and tools. Contact us for reliable emergency AC repair services in Lacombe, Red Deer, Sylvan Lake, AB, and surrounding areas, and let our experts diagnose and resolve the problem.
