The salesman was very knowledgeable and helped me out to where I was comfortable with the decision that I made. The installation took place four days after my sale. The installers were very respectful to me and respected my home. They explained the operation of the furnace very well and I understood the functions explained to me. They did a wonderful job cleaning after the installation was complete. I saw commercials and different ads on Four Seasons and decided to give them a try. I will refer Four Seasons to family and friends. Everything went well from start to finish.
