In Evanston, IL, having a dependable air conditioner is a must during the summer months. So when your AC starts acting up, one of the usual suspects is the compressor. This key component keeps the refrigerant circulating and helps your system maintain a cool temperature. When it starts to fail, you might notice your home isn’t as comfortable, and your energy bills might creep up, too. Here are some signs that could indicate that you have a faulty AC compressor.
Vents Blowing Warm or Weak Air
If your AC is running but the air coming out feels barely cool or even warm, your compressor might not be doing its job. It’s responsible for circulating refrigerant through the system, and when it’s on the fritz, cooling power takes a hit. While a refrigerant leak could also be to blame, a failing compressor is often behind this kind of poor performance.
Strange Noises from the Outdoor Unit
Hearing odd sounds from your outdoor AC unit? That’s not something to ignore. A healthy compressor hums quietly, but if you’re hearing clanking, grinding, or rattling, it might be a sign of internal damage like worn-out bearings or loose parts. These noises usually point to a compressor that’s struggling or breaking down.
Breaker Keeps Tripping
If your AC is frequently tripping the circuit breaker, the compressor could be drawing too much power. This often happens when it’s having a hard time starting up or staying on. It’s not just annoying—it’s a warning sign that shouldn’t be ignored. An overloaded circuit is a safety risk and needs professional attention right away.
Compressor Clutch Isn’t Engaging
The clutch on your compressor kicks in when the system starts cooling. If it doesn’t engage, the compressor won’t run—and you won’t get any cool air. The cause might be electrical, a broken clutch, or an internal issue with the compressor itself. Diagnosing this kind of problem is best left to a trained technician.
Vibrations or Shaking from the Unit
If your outdoor unit shakes or vibrates noticeably when it starts up, that’s another red flag. It could mean there’s an internal imbalance or that some parts are coming loose. Letting this go unchecked could lead to bigger problems down the road, even complete system failure.
Rising Energy Bills and Lower Efficiency
When a compressor starts to wear out, your AC system has to work harder to get the job done. That extra strain often shows up in your utility bills. If you’re paying more for electricity but your home doesn’t feel cooler, your compressor might be the issue. It’s a sign that something’s not working as it should.
