We had a very good experience with Convertible Heating and AC. Chris our sales person was far more knowledgable that the previous 2 salespersons providing quotes (pointing out problematic installation areas, standards that were not being met - things that are typically only uncovered by the installers who subsequently increase the price). He was always available to provide us with information before and after the install. Our two installers were great, very knowledgeable and willing to do the job right despite a difficult installation scenario for both furnace and water heater. I would definitely recommend this company and will continue to use them for my servicing.
