Geopan Heating

We purchased a Lennox high efficient furnace from Koss at Gropan Heating, Burnaby in 2009 and it came with labor and parts warranty for 15 years. However, we found he would try to upsell us to ask us to replace hot water tank when it was not needed and his quote changed everytime we asked for a quote to a service. We then went to other company for furnace service. On July 14th, we came across his Groupon promotion and decided to ask him to service the furnace. At the end of the maintenance, he indicated the Collector box was broken due to poor design of Lennox. He provided a quote for labor and parts. We reminded him that it should be covered under the warranty. He mentioned that the parts might not be if I can‘t prove the furnace had been serviced in the past 5 years (he never mentioned this to us before) and he would get back to us if the labor is covered. It‘S been two weeks but he has not responded to us.
