Both have their rightful place. Here are some things to consider: Gas furnaces may be cheaper to operate due to the relatively low cost of gas for the foreseeable future. When replacing a gas system, it is typically less to replace it with another gas system. Heat pump conversion requires a larger up-front investment. Heat pumps are considered a ‘green’ alternative to gas furnaces, especially when solar is utilized for the required energy. Heat pumps utilize the outdoor compressor for heating and can be noisy at nighttime or early in the morning when you need heat most. Modern heat pumps can run near silent outside, but it is crucial to choose the right model.
