We have a property with a tankless water heater, rented from Enercare Home. The tenant paid the monthly rental regularly, and when they recently moved out they closed their tank rental account, paying the balance in full. As owners of the property the water heater rental was transferred back to us. A few days later we received a bill from Enercare showing a balance of 1 year's rental for the heater - essentially billing us for the same year that the tenant had paid all rental fees, and cleared their final balance. When I called Enercare, their customer service people were of little help, essentially confirming that they could see the tenant had paid, and that we shouldn't have been billed. They explained that they would have to send it over to 'billing' and that it would take 48 to 72 hours to get a response. As it happens we have just sold the property, and have our lawyers closing the deal in 4 days. My issue is that a 'security' has been registered against the property by Enercare in the amount of what they say we owe them. So this is effectively going to put a wrench in the works to get the lawyer's paperwork finalized. To my annoyance, when I asked for an escalation, to get this reviewed by billing sooner, they told me that they have no direct or phone contact with billing, and all they could do was make a note on file, and wait for billing to get to my file. In these days of computers, networks, the Internet, and instant messaging, this is a totally archaic way of doing business, and extremely frustrating for customers. Enercare Customer Service is essentially a brick wall that prevents you talking to anyone directly about your bills. From this I really would not recommend anyone get into any kind of rental agreement with Enercare. Buyer beware!
