That Hissing Sound Means Heater Trouble

You need your heater running optimally and efficiently to help keep you comfortable. This means that if there is a problem within your system, you should address it fast. That is why it pays off to take the time to listen to your heating unit. We don’t mean trying to figure out how your system is feeling–we mean taking note of any strange noises that it makes.

When a heater starts to emit new and somewhat concerning sounds, it is absolutely something that should make you worry. Those noises are an indicator that something is wrong with your system. Let’s explore one of the most commonly ignore noises a heater can make that really shouldn’t be underestimated.

What Does a Hissing Sound Mean?

Yes, we are really talking about a hissing heating system. This is a noise that is far too often blown off as no big deal. The reality is that hissing can mean serious trouble for your heater. Here’s what might be causing this noise.

  1. A clogged air filter: This is what every homeowner hopes is the cause of a hissing heating unit. A dirty air filter may start to create a hissing noise simply due to air forcing its way through the debris. Change the filter to address this and protect your heater from further trouble. There is a reason we advise changing out your filter every one to three months!
  2. A refrigerant leak: If you have a heat pump or a ductless system, a refrigerant leak may be the source of your hissing sound. You likely already know that this is a big problem. Hissing due to a refrigerant leak means there is refrigerant escaping your system, which can harm both your comfort and your heat pump in the long run. Make sure to schedule repairs for a hissing heat pump ASAP.
  3. A cracked heat exchanger: Lastly, a hissing gas furnace is a serious issue. The hissing may be due to a cracked heat exchanger. If you suspect this is the case, you’ll need to shut your system down until your technician can come by to provide heater repair in Cypress, TX. What you are hearing is combustion gases escaping from your heat exchanger and entering the air being blown into your home. Don’t wait until you start smelling gas to take this seriously–shut your system down and call for repairs now.
