Heat Pump Making Noise: New Sounds Need Context
If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.
Unusual heat-pump noises need a service assessment when they are loud, prolonged, or different from the system's normal pattern. Banging, screeching, buzzing, and grinding do not identify a part by themselves. Note the mode and timing of the noise, then keep clear of moving equipment and request a professional diagnosis.
