New gas furnace and AC to replace inefficient electric heat and AC. Mark helped greatly by answering my questions related to selecting new equipment and preparing for the conversion. Communications were excellent, which made it easier to coordinate with the gas company, as well as 3rd party duct cleaners. Installation went smoothly and according to timeline.
Mark did a great job installing a split system in an upstairs bedroom of my home in Carmel. He was prompt, courteous and professional. I would be glad to use him again for other HVAC needs for my home
Mark came out on a Sunday very quickly after I contacted him. He determined the problem and was able to fit us in that same day after going to get a part. He communicated well on timelines. We are so thankful for his service while the heat index was 103! This was our first time having him work for us and will definitely do so again!
