Gas furnaces convert natural gas into efficient heat during the colder months of the year. Multiple stages allow for quiet operation and efficient temperature control. They are housed indoors, typically in a cabinet in the basement or closet. Matching the right gas furnace and air conditioner will keep your home comfortable all year long. Gas furnaces can also be matched with a heat pump to add energy-wise dual fuel capability for increased efficiency.
If you have any additional questions about gas furnaces, contact your local HVAC contractor.
