Installation was delayed by close to 6 weeks in Nov 2014. Then old furnace removed prior to new parts arriving. 3 weeks without heat. 4 months later flooding in April 2015 with 20 k damage due to inadequate drainage for high efficiency furnace that can produce I gal of water an hour. Contractor (Neil) would not cooperate in finding the reason for flooding. In addition, Gov rebates not registered and never received. Furnace/heat pump not registered with Goodman warranty. 2 years later parts which were supposed to be under warranty cost 2k to replace. Worst installer/contractor ever. Neil was rude and abusive at times in response to our queries. Even threatening.
