For 17 years we had a Summer screen room and decided it was time to have something more permanent. For The difference in price between a 3 season and 4 season we decided on the 4 season. some glad we did! We installed infloor electric heat and a ductless heat pump. Whether it’s February snowstorm , April showers or the July heat, we enjoy our 4 season sunroom. It’s the best room in our house for relaxing and entertaining.
