  • We contacted Bosanac Heating and Electric in late August requesting a quote on a new furnace and air conditioner. We were impressed by Mike’s prompt response and knowledge. We are very pleased that we chose Bosanac and referred him on the same day to our neighbour who purchased an air conditioning unit as well. The installation was very professional, clean, with our total satisfaction. Will definitely recommend them in future.

  • The AC was broken on a Wednesday, they came on Thursday, and our new AC was installed on Friday. The service tech, Adler, was very knowledgeable, friendly, and did a great job. (also has great taste in music)

  • We highly recommend Bosanac Heating and Electric. We dealt directly with the owner Michael for the replacement of our air conditioning unit. From start to finish, the entire experience was excellent. FIVE Stars The price was very fair and the workmanship was exceptional. The installation was completed on time and exactly as promised. The installation was professional, the installers very courteous, and the time was taken to address every question both before and after the installation. There were no surprises, and everything promised was delivered. We are extremely pleased with the quality of our Lennox air conditioner. Excellent service, excellent workmanship, a fair price, and a company that truly stands behind its word. I would not hesitate to recommend them to anyone needing HVAC services. Marty Rosato.

  • This was our second time using Bosanac and they have proven once more they are the best in the business. Our technician’s name was David and depth and breadth of his knowledge blew us away when we asked about his advice on a radiator unit we weren’t sure what to do with. A simple service call turned into an efficient learning experience that opened our eyes to what is possible. Excellent and efficient, have no fear when Bosanac is near, I’d give them 10/5 stars if I could.
