Heater system works great, as well as the blower units for all systems

Worth every penny. Period. Keeps the house evenly heated, and takes the chill out of the air quickly and efficiently.
Not happy
April 5, 2024
Blows big gusts of cold air when it starts up. Seems to not have a slow ramp up function. Heats fine. On heat, the Alexa interface is problematic. If I raise the temp using voice commands, the thermostat goes up but the heat doesn't start unless I raise it 5\-6 degrees. The thermostat shows the change, just the heat does come on. If I make that change on the app, the heat comes on.
Low Nox = high maintenance

Heater has had multiple service calls related to low nox requirements here in CA. A technician has had to come to my house 16 times since it was installed last year.

no labor warranty for a top of the line model... would be nice to have additional confidence that Carrier will cover labor cost if it fails in the first 2 years. Also a variable fan would be super as it seems that noise is loud when running on high, and coupled to the top of the line variable AC unit would make the entire system super effective
