Checking your AC compressor involves inspecting key components, monitoring performance, and performing simple diagnostic tests to identify any issues affecting its efficiency or functionality.

The compressor is the heart of your air conditioning system, responsible for circulating refrigerant and maintaining a comfortable indoor temperature. Regular AC maintenance, including inspecting the compressor, ensures your air conditioner runs efficiently and saves you from costly repairs down the line. Let’s dive into the details!

7 Ways To Check Your AC Compressor?

If your AC is struggling to cool down the room properly, your compressor might be the problem. Checking your AC compressor requires a step-by-step approach. Below are some of the most effective ways to do so:

1. Inspect for Visible Signs of Damage

Begin by turning off the power to your air conditioner for safety. Once the system is powered down:

• Look for Leaks: Check for refrigerant or oil leaks around the compressor.
• Inspect Wiring: Look for frayed wires or loose electrical connections near the compressor.
• Assess Physical Condition: Check for dents, cracks, or rust on the compressor unit itself, which can indicate wear and tear.

2. Listen for Unusual Noises

When the AC is running, listen to the compressor for strange sounds:

• Buzzing or Humming Sounds: These could indicate electrical issues or a failing motor.
• Clicking Noises: Often caused by a malfunctioning relay switch or a compressor struggling to start.
• Grinding or Screeching Noises: These are typically signs of mechanical problems and require professional attention.

3. Check the Compressor Fan

The fan within the compressor unit should be spinning freely when the AC is running. If it’s stuck, not moving, or spinning irregularly, the compressor might not be functioning correctly.

4. Measure Voltage and Current

Using a multimeter:

• Test the compressor’s terminals for proper voltage. Compare readings to the manufacturer’s specifications.
• Measure amperage during operation to ensure it falls within the expected range. Low or excessive amperage can signal a malfunction.

5. Perform a Hard Start Test

A “hard start” is when the compressor struggles to start or takes longer than usual:

• Hard Start Kits: If you suspect this issue, a technician can temporarily use a hard start kit to test the compressor’s ability to start effectively.

6. Test for Refrigerant Pressure

Low refrigerant levels can strain the compressor:

• Use a pressure gauge to measure refrigerant pressure in the system. Low pressure might indicate leaks or a failing compressor.
• It’s best to let an HVAC technician handle refrigerant testing and refilling due to EPA regulations.

7. Conduct a Compressor Windings Test

Using a multimeter in resistance mode:

• Test the resistance across the three terminals (common, start, and run).
• Proper resistance values confirm the windings are intact. A zero or infinite reading indicates a problem with the motor.

Pro Tip: Always consult your air conditioner’s user manual for model-specific instructions before conducting tests. For complex diagnostics, it’s wise to rely on air conditioner maintenance services provided by trusted experts such as ACS HVAC.  

 

Signs and Symptoms That Your AC Compressor Is Failing

The AC compressor is the heart of your cooling system, and when it starts to fail, it often provides several warning signs. Catching these symptoms early can prevent further damage to your system and save on costly repairs. Below is a detailed look at the most common signs of a failing AC compressor:

1. Warm Air Coming from Vents

One of the most noticeable signs of a failing compressor is when your air conditioner blows warm or lukewarm air instead of cold. This happens because the compressor is responsible for circulating refrigerant, which absorbs and dissipates heat. If the compressor is damaged, it won’t be able to maintain the refrigerant flow needed to cool your home effectively.

2. Reduced Cooling Performance

If your home takes longer than usual to cool or some rooms feel warmer than others, the compressor might not be operating at full capacity. A drop in cooling efficiency is often an early sign that your compressor isn’t working properly. 

3. High Energy Bills

When a compressor starts to fail, it often works harder than necessary to maintain cooling, leading to a significant increase in energy consumption. If your energy bills suddenly spike without any change in usage habits, your compressor might be to blame.

4. Tripped Circuit Breaker

A tripped breaker is a common symptom of an overworking or electrically faulty compressor. If the circuit breaker connected to your AC trips repeatedly, it’s essential to inspect the compressor. Continuing to reset the breaker without addressing the underlying issue can cause more significant damage to your AC unit.

5. Leaking Refrigerant

Refrigerant leaks around the compressor area can point to internal damage. When refrigerant levels drop too low, the compressor works harder to compensate, leading to potential overheating and eventual failure. Signs of a refrigerant leak include:

• Ice formation on the evaporator coil or compressor.
• Reduced cooling output.
• Hissing sounds near the unit.

A refrigerant leak requires immediate attention from a professional, as handling refrigerants is regulated by law.

6. The Compressor Doesn’t Start

If your AC unit runs but the compressor doesn’t start, it might be due to electrical or motor-related issues. This is a critical problem that renders your air conditioner incapable of cooling.

If you notice any of these signs, contacting air conditioner maintenance services promptly can prevent further damage and extend the lifespan of your unit. It is important to choose a technician who knows what they’re doing and has extensive experience in the industry.
