Here are some of the most common reasons that can make an ac compressor stop working.

Why Did My AC Compressor Stop Working?

If you find your compressor or heat pump not working the first thing to do is check the power supply. The unit could have simply become unplugged.

Check your thermostat. Try lowering the temperature setting by a few degrees and listen for the unit to start.

While a professional should always be called to repair the AC unit, it’s great for you to have a basic understanding of the parts involved. Some of these parts include the intake filter in your home or office space. It is vital to a properly working AC unit that this filter be changed regularly. Dirty or clogged filters are one of the most common causes that make your ac compressor stop working. AC coils and evaporators are other parts that need to be kept clean and maintained but they require professional knowledge and should be left to the experts.

Be realistic with the temperature setting on your thermostat. When it’s 110 degrees outside, don’t set your thermostat at 65. It just isn’t designed for that. Heat pumps do not perform as well on very cold days. They work by moving warm air from one place to another. When the mercury drops below about 30, there isn’t much heat to speak of.

How Do I Know If It’s Serious?

It can sometimes be difficult to decide when to call the experts. If you experience any of these symptoms, it’s best to leave the professionals to figure out what made the ac compressor stop working.

  • Unit turns off and on frequently – This is often referred to as a “hard start” and can be caused by an electrical problem within the compressor.
  • Reduced cooling – if your home or office doesn’t seem as cool as it usually does, your ac compressor may have stopped working properly because of suction issues. This should be addressed by a professional.
  • Overheating – overheating can certainly make your ac compressor stop working due to faulty wiring or motor issues. Anytime your ac compressor stops working and you notice ice or extreme heat, call an expert.
