West Palm Beach Air Conditioning Repair Question: What Causes Air Conditioning Hissing Noises?

If your air conditioning system is beginning to make strange or unusual sounds, you may need air conditioning repair in West Palm Beach. We know how important your air conditioning system is to your comfort, so its important to know when you should call for service. We’ve put together some of the most common reasons why your AC system is making strange noises

If you hear a hissing noise coming from your air conditioning, it is typically a leak of some kind. Leaks can not only raise the cost of cooling your home, but they can also make your system work harder which can increase the general wear and tear on your air conditioning system. Here are some causes for air conditioning hissing:

  • Too much compressor pressure. This can be a serious issue requiring your immediate attention. If you think your compressor is hissing, shut the system off and call Envirotech for air conditioning repair in West Palm Beach.
  • Expansion valve. Your expansion valve is part of the air conditioning cycle that rapidly expands the refrigerant. During normal operation, the expansion valve may emit short intermittent hissing sounds and shouldn’t last for long. But if the hissing is long and uninterrupted there might be a problem with the valve.
  • Ductwork. As the cool air exits your ducts, they may emit a hissing or whooshing sound. This is not typically a cause for concern and has to do with the shape of the register and vents more than anything else. That said, it can sometimes indicate a leak somewhere within your duct system, which means that you’re paying for cool air that doesn’t reach the inside of your home.

Whatever the cause of the hissing sound in your home, call Envirotech Air Quality Services for air conditioning repair in West Palm Beach. We can also enroll you in our preventive maintenance program so that your cooling system is inspected on a regular basis.
