Speaking of customer service, our furnace stopped working today, has an error code.
Texted our HVAC provider. Got a response, on a Saturday of a long weekend, in 20 minutes. They forwarded my number to the on call tech. He called less than 10 minutes later. Will be here in a couple of hours.
ON A SATURDAY OF A LONG WEEKEND!

No complaints here, unless he borks our furnace (that would be point #2 mentioned above), but they nailed point #1!
