Long story short - DONT call them for service, even if you are desprate. They will provide you service, rip you off and charge you a fortune int he mean time. I had a part go on the hot water tank, they said that it was either Part A or part B....came and fixed part A and the next day the tank broke. They said theyd gladly fix part B for another $600 on top of the $500 they had already charged. Outraged, i complained, he said hed refund my money in full by cheque, and it just happened to never show up. The most shady business and business people in the word.
