What’s the average cost for a central air compressor?

The four parts used in most central air systems are the compressor, evaporator, expansion valve, and a condenser. Of these parts, the compressor is responsible for circulating coolant through the unit. It does this by compressing freon into a high temperature gas that is then pushed through to the outdoor coil, where at this time the heat is radiated away. From here the coolant returns to liquid form to be pumped back through the interior coils to suck up heat and turn back into gas again. This process cycles over and over again to maintain a cool temperature inside your home or office.

Depending on the model and make of your unit, on average the cost of a replacement compressor can run from anywhere between $300 to $600. However, this is only the cost of the part itself, and hiring a technician will cost you about $1500 to $2000 on average. Seeing the difference in price, it may be incredibly tempting to make a repair job yourself. The caveat is that you need to have an HVAC license in most states to legally work on an air conditioning unit. So while it doesn’t hurt to do further research into what could be a small issue, if it’s something you can’t fix without opening up your air conditioning unit, the chances are that you’ll need to call someone.

Signs a Compressor Needs Replacing

Like many machines, there are several common signs that can tell you whether or not your compressor needs to be replaced by a certified technician. Below is a list of some common problems caused by a faulty compressor. These issues can be caused by wear and tear due to high usage, power surges burning out the circuits of the compressor, or excess moisture buildup causing chemical damage to the unit.

  • The number one sign a compressor needs to be replaced is that your unit no longer blows out cool air.
  • The fan is no longer audible when you turn on your air conditioning unit.
  • Loud noises are coming from the inside of your A/C.
  • The clutch of your air conditioning unit remains still and does not move.
  • Fluid leaks develop at the connectors of your compressor.
  • Dust and other material clogs the compressor’s fan and causes the motor to burn out.

What Are The Symptoms Of A Bad AC Compressor?

A bad AC compressor can turn a nice day into an overheated nightmare. Your compressor is one of the most important parts of your cooling system and a common point of failure when things go wrong. Below are just a few symptoms that could indicate that your system is failing.

Signs of a Failing Compressor

In most cases, the first sign that you’ve got a bad compressor will be the fact that your system is blowing warm air. There are other causes, of course, but systems that are on the verge of compressor failure often start to blow warm air instead of cooling down your home. If you notice a sudden change from cold air to warm, there’s a very good chance that you’ll be dealing with a failed compressor in the near future.

You might also notice some power consumption problems if your compressor is in bad shape. If your circuit breaker is frequently tripped when your air conditioning unit is turned on, there’s a very good chance that your compressor is overheating and drawing in too much power. It’s very important that you don’t keep resetting your circuit breaker in this case – if your compressor stays in the state, you might be looking at a catastrophic failure.

Other signs are a little more dramatic. If you notice that your condensing unit is violently shaking every time that you turn on your air conditioning, there’s a chance that your compressor is having trouble turning on. Likewise, a nosy condensing unit can often be a sign that a compressor is starting to struggle. If you’re dealing with either of those signs, there’s a good chance that you’ll need someone to look at your air conditioning unit quickly.

The most dramatic sign of compressor failure, though, is that the compressor stops working altogether. There’s not a problem with the power supply and your indoor fan will keep blowing, but the compressor simply isn’t making any noise at all. If attempts to lower the thermostat aren’t met with any success, you’re probably looking at a compressor that has already failed.

If you think that your compressor isn’t in good shape, it’s better to call for AC repair sooner rather than later. As you can see from the information above, some of the problems that indicate a bad compressor can actually be quite dangerous. If you want to make sure you have a cool home and a working AC compressor, don’t delay – call O.C. McDonald at 408-295-2182 to get the help you need today.
