Roop and colleague did a great job of installing the furnace and AC. Admittedly, this was not a straightforward install, and part of the finished ceiling needed to be cut for venting. This additional work was done competently at no extra cost. We were offered a great deal in purchasing both furnace and A/C with great options for extending the warranty by Marnie. Marnie has been very helpful in answering all questions and attending to concerns in a timely manner. We are very glad that we went with Convertible to fulfill our rental property's HVAC needs. Thank you!
