Gas furnaces are the most common heating system in Seattle homes. They use natural gas to produce heat quickly and efficiently, even during the coldest Pacific Northwest nights.
Electric furnaces use heating elements to warm air without combustion, making them a great option for homes without a natural gas connection or where gas line installation isn't practical.
Not sure which system you have? No problem — our technicians will identify your furnace type and recommend the best service plan.
