There are a variety of reasons why your AC compressor might not be turning on, ranging from simple issues like a tripped circuit breaker to more complex problems like a faulty capacitor or compressor motor. In this blog post, we’ll explore the common reasons why your AC compressor might not be turning on and provide tips on what you can do to get your air conditioning system back up and running.

What Is an AC Compressor?

An air conditioning compressor is a vital component found in an AC unit. This part takes all of the hot air that’s in your home or apartment. It then transfers it outside using the cooling agent known as refrigerant.

When it’s hot, refrigerant is in a gaseous state, but it transforms into a liquid when it becomes cold. The AC compressor provides the pressure necessary for the refrigerant to change from gas to liquid, and the compressor unit disperses the liquid refrigerant throughout the system. When air blows on the refrigerant, it cools down, which is how the air inside your home becomes colder, despite the hot air outside.

Signs That Your AC Compressor Is Malfunctioning

As you can see, an AC compressor is a vital component of your air conditioner. Without it, the hot air can’t be properly cooled down. That’s why it’s important to recognize the signs that your AC compressor is malfunctioning. In this section, we’ll discuss some of these signs.

1. High Energy Costs

When an AC compressor is malfunctioning, it runs for a more extended period to get out less cold air. This typically happens when an expert installer hasn’t set up the AC compressor. Not only does this waste money, but it also contributes to climate change

So make sure to pay attention to your energy bill. If there isn’t an easy explanation for the increased energy cost, the problem is likely your compressor. 

Tired of high energy costs but can’t afford a new AC compressor? Don’t panic. Instead, explore the vast array of financing options that we provide here at Performance AC.

2. Strange Sounds

Your air conditioning unit is bound to make some noise. But there’s a big difference between some normal humming and strange sounds. If you notice rattling or the system turning on and off frequently, it’s time to call a professional. 

It’s likely a part that’s worn down. Sometimes the solution lies in a quick compressor tune-up. Other times, you will need to replace the part entirely.

3. Refrigerant Leaks

When a compressor is no longer working at peak capacity, it will begin dispersing too much of the refrigerant. This, in turn, causes it to drip out of the AC unit. If you notice liquid coming down from your unit, it’s a clear sign that your compressor will need to be repaired or replaced. 

4. Weak Airflow

If you notice weak airflow or reduced cooling from your compressor, it may indicate slight damage. While it may gradually get weaker, catching it early enough can allow for repair rather than replacement.

5. Warm Air or Hot Condenser Unit

When your compressor is completely cooked, it will start spewing out warm air instead of cool air. When this happens, you will likely need to replace the whole thing. There isn’t much that can be done in terms of repairs.

AC Not Working? – Common Issues

There can be multiple reasons why your AC compressor isn’t operating correctly. Some of the common problems that we encounter include things like:

  • The compressor is shutting down for safety reasons to prevent further damage
  • The compressor has a dirty filter
  • The compressor has a dirty condenser coil
  • The refrigerant levels are slightly off
  • The compressor’s capacitor failed
  • You’re experiencing electrical problems
  • Your thermostat is broken
  • Your wiring is bad

Some solutions to these problems will be pretty straightforward. For example, if your thermostat is the problem, you can likely replace it. However, if you don’t know how to fix the problem, or you don’t even know what the problem is, then you should contact a professional.

AC Compressor Replacement Costs

Replacing an AC compressor can be a costly expense, with new compressors costing roughly $1,500. While it may be worth it to replace a window unit, determining whether to repair or replace a central heating system depends on various factors.

It’s crucial to consult professionals like Performance AC to make an informed decision. Our team of experts will evaluate your system and provide you with the best solution to meet your needs and budget. Don’t let a faulty AC compressor compromise your home’s comfort.
