I called Star Alliance for a quote to upgrade our very old furnace and air conditioner. Jacky showed up on time the next day. I was most impressed by his knowledge and professionalism. He explained what we had and what we need. He provided us with options and price quotes on different Lennox models. We signed a contract with him the same day and he arranged for installation a week thereafter. Jason and his helper arrived as scheduled, on time, for the installation. Both the furnace and AC unit were installed in under 10 hours. They worked hard, kept the place clean and tidied up afterwards. I was most appreciative of the little things that matter --- covering the stairs and carpeted areas with tarp; removing all the cardboard boxes; hauling the old furnace and water heater to the sidewalk; and, giving us with no additional charge, a cover for the AC unit and a pretty nice Honeywell programmable thermostat. Oh, did I mention that the price quoted for the whole job was more than fair and reasonable ? Jacky even arranged for the auditor to come and conduct the energy audit on the same day so we can apply for the rebates from Enbridge. He also contacted Lennox on our behalf to register the furnace and AC unit for warranty purposes. Overall, I enjoyed dealing with Star Alliance and would recommend them highly to anyone looking to update their furnace and AC unit. They are absolutely wonderful people to deal with.
