I had a guy by the name of Andy come to my home for a service. He was very knowledgeable and explained all of the furnaces that I was interested in. They came out the next day to install my furnace and I was very pleased to see the installers arrive on time. The installers were very respectful of me and my property and made sure they updated me on the installation. Ive used Four Seasons in the past so I wanted to have a company I trust install my furnace. The quality control inspection is a great follow up.
