  • 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.

    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.
