Just installed our Champion 14.4KW whole house automatic standby generator. Entire experience was excellent. Immediate callback and contacts. Courteous, prompt, competent, on time, on schedule, able to solve difficult issues that others would have given up on. Installed new high tech devices on my 2 central air units that dropped start up amps to 25% allowing this smaller quieter generator to power my entire 200 amp service with no circuits left out and everything running full power. Awesome! hi
