We recently had a Lennox ML296 furnace and a ML14XC A/C installed in July.
From the beginning when either unit started there was a noise like an airplane taking off(whining) both on start up and shut down,
The installer has replaced the motor and fan and there is no difference.
Any help or suggestions would be appreciated
