ML14KP1 Heat Pump
5/5
Very Quiet and Does the Job
March 01, 2026We are in Florida where we have recently experience frost on several nights and mid 80's temps the following days. The new Lennox put out tons of heat on the frosty days and then switched over seamlessly to the AC when the temps rose into the mid 80's. We particularly enjoy the Lennox smart thermostat. I can monitor the house remotely. The only criticism we have is that the heat tends to overshoot the target temps, but I think we can work on those thermostat adjustments.
Yes, I recommend this product.

It's OK
March 01, 2026It takes a bit to get warm air. When the fan first starts, it can be chilling.
