Many homeowners are often unaware of what constitutes bad ac compressor symptoms and when their A/C units start having trouble working as it should. The ideal time to notice an air conditioning compressor problem is when it starts to happen: Compressors can go bad for a lot of reasons, some of which we will examine below. Regardless of the reason, if you notice the compressor is starting to have problems in the early stages, you’ll be able to make early repairs and avoid a large A/C compressor replacement cost. It’s crucial to know how to tell if your A/C compressor is bad. Some of the signs of a bad A/C compressor are as follows. If the unit vibrates when it starts, it may mean that the compressor is “Hard starting,” or having problems starting – a telltale warning sign that the air conditioner compressor is about to fail. Failed compressors can be expensive to replace so how to know if the A/C compressor is bad is vital. If your fan is running but your AC compressor is not, the outer unit housing the compressor may be the culprit.
Air conditioners need refrigerant to cool down the warm air your AC system absorbs from your home. If you have a faulty compressor, the rest of the parts will be missing a crucial component, leaving you with no cold air.5 Signs & Symptoms of a Bad AC Compressor. This is one of the early signs of a problem with the compressor: The AC is still working, but you’ve noticed less air is coming out your air vents.
Before we look at common compressor issues, it’s important to understand what the compressor does. The purpose of the compressor is to condense the refrigerant such that it’s circulated to the evaporator coils found inside the indoor unit of your home’s AC system. If the compressor doesn’t turn on, it could mean that your compressor has failed already.
Here are 5 telltale symptoms of AC compressor failure. Here’s what’s happening and what it means when you experience the symptoms of AC compressor failure listed above. The lesson: Don’t ignore symptoms of AC compressor failure.
Because of that, you should always be on the lookout for signs that your car air conditioning compressor is bad. The good news about that bad news is you almost always get clues that your air conditioning is about to fail. You might look at the air conditioning compressor as the heart of the air conditioning system in your car. If you have the air conditioning switched on, the temperature turned down, the fan cranked up, and the air coming out of the vents doesn’t seem as cold as it used to, it may not be your imagination.
If it acts funny, it helps to know if an AC compressor is going bad before it breaks down completely. It’s not actually the big metal box outside your home connected to the indoor HVAC. The AC compressor is inside the box along with other components. A jump in your electric bill is another way to know if your AC compressor is bad. If your electric bill climbs without an obvious reason, call for an HVAC inspection.
Puddles in strange places and excess moisture are both signs of leaks in your system. Keep in mind that leaks can occur anywhere in the compressor circuit, not just around your AC unit, and that a leak can pose significant health risks to you and your family. If your AC system starts to leak its refrigerant content, whether from the coils, the compressor, or another area of the unit, the HVAC system itself will eventually stop working.
how to know if air compressor is working Related Question:
What happens when ac compressor goes bad?

What causes AC compressor failure?
High voltages can also damage the motor causing the compressor to overheat. Moreover, dirty coils, low refrigerant levels, and lack of insulation; all can contribute to compressor overheating, ultimately resulting in compressor failure.

How often do AC compressors go bad?
Compressors are actually very dependable (lasting on average between 12-15 years) so typically, when your AC compressor has gone bad there’s an underlying cause that needs to be addressed lest the problem reemerge even after the unit has been replaced.
Will a bad AC compressor affect the engine?

If the ac compressor is affected, it will affect the engine because when the compressor’s pulley bearing defaults, it will stall due to the stuck compressor.
What noise does a compressor make?
