"I HIGHLY! HIGHLY! Recommend this company!!! We met with several different heating & cooling businesses to get bids on replacing our 27 year old system. We decided to go with this company because we really liked the way Sean Henson inspected our old system and presented different options for us. He was very thorough in his explanations and answered every question we had. There was no high pressure to buy the most expensive system or to buy at all which is always great when your trying to get bids. Their costs are competitive and reasonable. Once we chose this company our installation was scheduled within 2 weeks and because our place is only 1145sq.ft. took a day and a half. Alex and his hardworking crew did a phenomenal job on are very old system. There were a few things that had to be brought up to the current codes and everything was done well. After each day the crew made sure everything was cleaned up. What a difference this new System made. It runs so well now and every room is nice and cool or hot depending on the need."
