"Don't buy Lennox"

1.0 rating
Very Unsatisfied

Had a Lennox heat pump installed in 2010 for a large room over garage. Unit is used on occasional basis. It as broken down 2 times in 5 1/ 2 years. Melted heat strips, shorted blower. Still not repaired after 2 weeks. Waiting on parts. We have a Trane unit on the main level with minimal issues for over 10 years. Buy the Trane. It is very reliable.

"Flawless performance for over ten years"

5.0 rating
Very Satisfied

Flawless performance for over ten years. Only service was to keep filters changed. Cut electric bills in half, heats at 10 degrees F without cutting in backups. I can only say the unit works. If it dies tomorrow, will be from salt air and corrosion. It stomped the performance of the previous systems. I would recommend this unit without reservation.

There are also posts on the same site regarding problems with high and low pressure faults and with problems that appear to be the fault of technicians, including overcharging with Freon.
