    It would be helpful if you played the sound each of the issues would make.

    Something in a neighbor's yard is buzzing 3 times, every 3 minutes and 15 seconds. All day and every day. Any ideas would be VERY appreciated.

  • My heatpump just started buzzing every 2 + minutes. Sounds like the compressor is trying to start but shuts back off.

    The noise im hearing is like a game show buzzer and it’s at seemingly random intervals
  • Just had my A coil cleaned and replaced and now there's a loud hum every 30 seconds. Please help. The technician that's doing the work already tried to rip me off once now this. 8 I'm old and really sick. I need help, please.

    Is it common for a brand new unit to hum when turned on? The outside unit is making a loud humming sound and I can only trace it to the compressor inside the outdoor unit. It’s a carrier seer 15 unit. I mentioned it to the installer and they say it’s normal. 🤷‍♂️
