I did not plan to upgrade my furnace before my energy auditor came, then I decide to upgrade my 20+ years old furnace as well persuaded by the auditor, knowing the government encourages the home-owners to do so by providing several rebate programs. After reviewing the top rated contractors on line and some top-line furnaces as recommended from consumer report, I finally locked on two brand and model “Bryan - 355AAV042060” and “American standard - AUH2B060A9V3VA”. The next step was to collect several quotes and finally signed the contract with Rocky Wang from “High Efficiency Cooling & Heating Inc.” as the other reviews said and I second that Rocky sat down with us and explained the costs, as well as the rebates we'd be eligible for, and the estimated savings in gas and electricity. He simply was willing and able to answer all my questions in detail. I chose this company because they are members of TSSA, HRAI and BBB and 5 years labour warranty without any precondition. But I was not sure at the time that they would be really delivering as they promised to. Within one week, the Installer MR. Li was sent in and he had spent a whole day from 10 to 7 in my furnace room and saw their jobs were nicely done in the end – which I heard he has tremendous experiences and he extremely professional and process-oriented. Mr. Li and his assistant even re-tape my existing duct and replace my old condensation drain and feed it into the condensation water pump with the new drain pipe. I definitely recommend to others and they will not let you down. Again thanks to Rocky and Mr. Li.
