Efficient Furnace
October 28, 2021
Used this furnace for a year now. The variable features are nice, as it heats the house evenly and is much more efficient that the single stage. Would recommend this furnace to everyone. Had no issues with humidity.
Very disappointed. Nothing but problems.

Worked well the first four seasons, then the problems started. Gas valve failed at the start of the fifth heating season. Warranty did not cover everything and the cost was over 400 dollars to fix it. At the start of the seventh heating season it threw an error code and stopped heating. Got it checked out and the heat exchanger rotted through in just six years! Thankfully the warranty covered this part as it would have been a major expense. At the end of year eight I started receiving another error code, but seemed to work okay after a reset. I constantly worry about the furnace breaking down while I'm away. If I'm gone for more than a few days in the winter I turn my well pump off because I can't trust this furnace will be working while I'm gone. Sad. I used to equate Carrier with quality and dependability, but not any longer.

With the variable speeds... You don't feel the drafts a forced hot air normally has. I have had to put streamers on the air outlets to know when the furnace is running. Very hard to tell. Love it..
