We can't say enough about Convertible Air, and particularly about Marnie, our contact, and it would seem, personal home heating specialilst! We found Convertible, oddly, at the CNE where they had a booth set up one year, and the gentleman who ran the booth was just wonderful, and convinced us to have hi s company come in and take a look at the system we were replaceing (renovating an old house, and inproving the entire heating/cooling system). Marnie showed up and took us through what was needed and perhaps more importantly, what wasn't. She was very knowledgable, efficient, and pleasant. We hired them and were not disappointed. Their price was great, and their installation and followup service was excellent. More than once we called them to get other work done, and they never tried to upsell us - in fact, sometimes even after coming over to our house, and inspecting the job, they would tell us it wasn't necessary and cheerfully go on their way. When we bought our next house, we thought we had a serious problem with the existing furnace - Marnie came right over, new baby in her arms and helped us out. We have recommended Convertible several times with great success - the only problem we have even been told of is that since they are a smaller, family owned company, it can take a while to get your initial call returned. But please don't get discouraged, they're great.
