Gas Furnace FAQs


  • What is the average lifespan of a gas furnace?

    Gas furnaces typically last between 15 and 20 years with proper maintenance and care.

  • How often should I have my gas furnace serviced?

    It’s recommended to have your gas furnace serviced once a year by a professional HVAC technician to ensure optimal performance and efficiency.

  • Can I install a gas furnace myself?

    It is not recommended to install a gas furnace yourself as it requires technical knowledge and experience to ensure that it is installed safely and correctly.

  • What is the difference between a single-stage and two-stage gas furnace?

    A single-stage gas furnace has only one level of heat output, while a two-stage furnace has a low and a high heat output option. A two-stage furnace can be more energy efficient as it adjusts the heat output to match the temperature needs of the home.

  • What size gas furnace do I need for my home?

    Most gas furnaces require electricity to operate, so they may not work during a power outage unless they are equipped with a backup generator or battery.

  • How can I improve the efficiency of my gas furnace?

    Regular maintenance, such as cleaning or replacing air filters and having the furnace serviced annually, can improve the efficiency of a gas furnace. Additionally, upgrading to a programmable thermostat and properly sealing and insulating ductwork can help reduce energy waste and improve efficiency.
