Get matched with top air conditioning pros in Harwood Heights, IL

"We decided to use Shavitz Heating & Air Conditioning as the company for the install of our new furnace. What impressed us about Shavitz was their employees. They made the entire process a positive experience. Everyone that interacted with us had a friendly and professional demeanor. It started with the sales visit by Will Gutierrez who was a pleasure to deal with. He provided us with several options while never pressuring us to lean one way or another. He was patient with us and answered all our questions. His courteous approach gave us a positive view of the company he represented. The installing technician, Linas, and the tech that was assisting him only continued this professional trend. They both were equally as courteous. Once the work was complete, Linas made sure he answered all of our questions and that we felt comfortable with the operation of our new furnace and humidifier before he left. His patience was very much appreciated. He also made sure the area were the work was done was clean and all trash removed. Will Gutierrez followed up with us a few days afterwards to make sure all was well, and that we were pleased with the work and our new purchase. Our answer was a definite, yes."
