![]() Reach out to our team for expert AC repair in Pittsburgh, PA. The bottom line is, if you notice anything unnatural about yoru AC operation, it’s time to give our pros a call! Your AC systems needs refrigerant to successfully flow into the evaporator coils at high pressure in order to operate, and if this isn’t happening then your system won’t be able to actually cool.Īnother sign of compressor failure is strange noises-for instance a hissing noise can mean a refrigerant leak, which will lead to compressor problems, or you may hear the compressor itself struggling to start up, hard-starting, or humming very loudly. So it’s a safe bet to buy and install those parts right away, especially if your air conditioning service unit is older than five years. Of course, you’ll never get to ponder whether or not you should replace your compressor or not if you don’t even know that the compressor is the cause of your air conditioner problems! Fortunately, there are some telltale signs to watch out for that indicate compressor failure.Ī lack of cooling, for instance, is a sign. Buy Parts The AC contactor (relay) and start/run capacitor (s) (see illustration below) fail most often and are inexpensive. “So, How Do I Even Know I Have a Compressor Problem?” You can experience ductwork problems, refrigerant leaks, and broken down components. A mismatched indoor system can start having problems due to the functionality and efficiency of the newer outside unit. So, what about replacing just the outside unit rather than the whole entire cooling system? This is a possibility, but again, you’ll want to consider age. What happens when that air conditioner breaks down anyway just a year or two from now? Then you’re stuck replacing the entire system, anyway. So if a compressor fails, it is worth replacing? Think of it this way-you’re putting a brand new, pricey, compressor inside a failing system. ![]() If the warranty is still good, then you should be able to have the compressor replaced at no cost to you because this shows an AC defect.īut, what if your air conditioner is 10-15 years old? This is the average lifespan of an air conditioner, even one that is very well taken care of throughout the years. For instance, how old is your air conditioner as a whole? If it’s only a few years old and you’ve been having it regularly maintained, but the compressor failed anyway, it’s time to look and your manufacturer’s warranty. This isn’t bad news necessarily, depending on some factors. In fact, compressors are the most expensive components of cooling systems. When it comes down to it, it may simply be best to replace the entire air conditioner, and here’s why: Compressors Are Expensive! The real question you should be asking here is, “should I replace my AC compressor, replace the outside unit of my cooling system, or replace the entire air conditioner?” To be honest, the answer to this is, “it depends” and that’s why this blog post is so important. So, if that’s the case, why are we even writing this blog post? If repairing the compressor isn’t possible, isn’t the only option to replace it? The national cost for an ac compressor clutch replacement in 2023 is between 1 with an average of 488. The compressor of your air conditioner is essentially the heart of the system, responsible for allowing the refrigerant process that even makes it possible for your cooling system to… well… cool. Let me know the results to this and we can go from there.Here’s the thing-you can’t repair an air conditioner’s compressor if it breaks down. If it does not ground it then you will not have anything. If the PCM grounds this pin then you will have 12 volts on your meter. You do this by turning the AC on with the relay removed, put your red lead of your meter on battery positive, and the black ground lead on pin 85. Next check to see if the PCM can ground pin 85. If so, the fuse, and wiring to the compressor is okay. The average price of an AC compressor clutch is between 8. ![]() First, remove the relay and jump pin 30 to 87 and see if the compressor comes on. This causes the relay to close and power from pin 30 goes to pin 87. This system is pretty simple in the fact that the PCM commands the relay to close by grounding the pin 85 on the relay. I attached a wiring diagram and we need to find out why we don't have power to the compressor through the normal circuit. You will lose this if you jump it all the time. The high pressure switch monitors the pressure and when it gets too high it shuts the compressor off. Basically if you jump the compressor it will not shut off and just continue to build pressure until the system bursts and you have a major failure on your hands. ![]() ![]() It is not safe to drive it this way as you are bypassing the safety system built in which is the high and low pressure switches. ![]()
