Worse Service and charged higher than COSTCO and other competitors.. Be aware of the HIDDEN COST after the installation. I wish I can give a zero star. I got Gas Water Heater installation and service from Home Depot and very disappointed. This is the last time I use Home Depot Home service. Home Depot sub-contract to Aire One Heating & Cooling. The service guys are unprofessional and careless. The thing was when he performed the gas line, he did not turn the gas vale off before he cut the pipe. Lucky, the other guy remind him. Otherwise, I don't know what will happen. Just imagine!!! The second thing is the Home Depot quoted me one way and charged different price which is over $300 more than what we agreed on. We tried to call Home Depot Home Service numerous times, but problem never solved! VERY DISAPPOINTED AND UNHAPPY CUSTOMER.
