Hearing Scary Noises From Your Heater? We Can Help

There are noises that are normal for your heater to make and noises that aren’t. In most cases, it will be apparent which noises are the bad ones. These are the sounds that make you stop, listen, and go, “What in the world was THAT?”

Hearing concerning noises coming from your heating system is worth a call to a professional. At the best, you may just need to give your heater some maintenance, which we are happy to provide. However, those noises are more often indicators that you need heating repair in Airway Heights, WA—before you need to get a new system altogether.

The 6 Sounds Your Heater Shouldn’t Make

If your heater needs repairs, it is best to get them taken care of by a professional promptly. Needing repairs is normal and having a pro fix your system ensures these noises stop and your system works correctly again. Make sure to reach out if you hear any of these sounds:

  1. Rattling: This sound usually indicates there is something shaking around in the system. It may be a loose bolt or screw. While this may not sound like a big deal, it is best to have a professional address the noise now rather than wait for things to worsen and the repair to get more expensive.
  2. Booming: This is a noise you might hear if you use a gas-powered furnace. What you are hearing is the impact of delayed ignition in the furnace. There is build-up in your burners which is making it hard for the furnace to ignite the gas supply. This allows gas to build up until it does ignite, creating that distinct booming noise. As you can imagine, this is extremely hard on your system—and thankfully it is avoidable with maintenance.
  3. Hissing: This is a big one because it can be especially serious if you have a furnace. A gas-powered furnace that is hissing may have a gas leak in the gas connection or heat exchanger. This is a serious safety issue that requires prompt action. Hissing from a heat pump can also be problematic as it can indicate a refrigerant leak or a problem with the airflow. In either case, get in contact with a professional ASAP.
  4. Buzzing: Is your heater emitting a buzzing or a humming sound while in operation? This is usually an indicator of an electrical problem in the system that requires expert repairs.
  5. Whistling: Have a heater that is trying to whistle a tune? It isn’t alive, but it may need a new filter! Make sure to check and change the filter if it is too dirty. If this doesn’t stop the whistling, it may be time to call a professional to check your ducts.
  6. Screeching: Does it sound like your heater is screaming at you when it is in operation? This can happen whether you have a heat pump or a furnace. Screeching is created by metal scraping against metal, such as when your system has a loose fan blade or a dry motor belt.
