Blowing hot air

Macaca
Community Member

My Nest thermostat has been pretty reliable for a few years in controlling my heat pump. The other day I turned on the AC and it would blow only warm air, even though the Nest says cooling is on.  I have not changed a thing. I restarted the Thermostat but that didn’t help. So I assume it’s either the Nest or circuitry internal to the heat pump. Before I call a service tech, is there any diagnostic I can run to tell me where the problem is?

Turned out to be a broken thermostat. I replaced the unit and all is well.

Hey Macaca,

 

Thanks for reaching out and we're sorry for the delay.

 

Let's try the following before calling your HVAC technician:

  • Check your HVAC fuse and switch
  • Take a look on your HVAC filters and drip pans
  • Make sure that all wire are properly inserted on your Nest Thermostat
  • Try changing the OB wire orientation by following the steps here.

Let me know how it goes by replying to this thread.

 

Regards,

Ryan
