Satisfaction with new Carrier furnace.
July 16, 2026
The performance last winter in Cleveland was excellent. It exceeded my expectations. On the downside a product this expensive should have a labor warranty longer than two years.
Sadly disappointed. We have another Carrier unit and have been very pleased with it. But the new one does not heat properly.

We have had to have the installer out several times as this unit does not seem as effective as the 15 year old furnace we had replaced. In extreme cold weather this winter, it would not heat to the thermostat setting and dropped to below 60 degrees on at least two days and was usually 6 degrees below the 68 degrees we had it programmed to run. There also seems to be a lot of condensation in our basement now that it is warmer, which did not have in the past.
Great furnace
