Sales person seemed very nice. I'd done my homework & wanted to eco-friendly, so chose Hallowell Acadia heat pump & Rinnai tankless hot water heater. Initial prices went up as I wanted to use the tankless hot water heater for backup. This required a manifold for heat exchanger. Fine, went with the install. This took 2 days since they forgot the equipment needed to charge the system. That would be OK except the installation team seemed incapable of closing the door behing them on a -14 C day. One would think that after they had removed my furnace keeping the door closed might be in order, never mind the fact that I'm in a downtown neighbourhood on a main street with a house full of stuff that could easily be taken when nobody is watching.
After the install was finally done, the system started giving me error messages and reverting to emergency mode, running off the hot water heater. No savings there! After several escalating service calls, they finally determined the problem was an error in calculating the size of return air duct needed. They left saying they would be back when the necessary items arrived. That was in March. I've left several messages with the sales person asking what was going on and haven't even received the courtesy of a reply.
I was also told that if any new rebates came available that Enwise would automatically apply for them on my behalf. The day the installation of the hot water heater Enbridge came out with their $300 rebate for going tankless. I've heard nothing from Enwise.
After spending this much money with a company, I expect to receive much better service than this. I rate them a ZERO because they haven't met ANY of my expectations for a reputable firm.
