Signs It's Time To Replace Your A/C Compressor

If you have a central air conditioning unit keeping your home cool, you also have a compressor. This is the outside part of this type of A/C unit. It pretty much does all the heavy work for your cooling system so the refrigerant can do what it's supposed to do. 

The compressor is so-named because it "compresses" the refrigerant in your air conditioner. This allows your system to remove excess humidity and cool down your indoor spaces.

While it's a durable component, a compressor does sometimes need a replacement. Read on for our list of signs suggesting you may need to replace your A/C compressor.

Unusual Noises

Odd sounds that include "chattering" or "ticking" is a sign that it may be time to replace your A/C compressor. These are sounds you might hear when your air conditioning compressor is cycling on or off. Rattling or rumbling when the A/C is on suggests mounts inside the outside unit are failing. The motor may also be loose.

Vibrations When Your A/C Unit Starts

When an air conditioning unit vibrates as it kicks in, it's referred to as a "hard start." This is a sign mechanical parts are having trouble getting things started. If this pattern continues, it may be time to replace your compressor before it fails.

Reduced Airflow (or Warm Air)

Another thing the A/C compressor does is generate cold air. But, if this part is weak, you may notice diminished airflow. A more noticeable sign involving airflow is warmer air inside your home. This could also be due to a compressor that needs a replacement. But, this could also be a sign of low refrigerant. For this reason, it's best to contact us about anything with airflow and temperature.

Leaking Refrigerant (Water Puddles/Moisture)

Refrigerant is what actually turns warm indoor air into cool, comfy air. But if it's leaking, you may notice puddles around your A/C unit or excess moisture. Refrigerant will run out if it's leaking and cause your compressor to stop working. Leaking refrigerant doesn't always mean you'll have to replace your compressor. But, it's a problem best dealt with as soon as possible to prevent serious damage to your outside unit.

Frequent Circuit Breaker Tripping

A failing A/C compressor may overheat and draw more power from your home's electrical supply. When this happens, your circuit breaker would trip, which is what it's supposed to do to prevent a fire. In this instance, the problem is with your compressor and not the breaker.
