  • How long do furnaces usually last?

    Heaters typically last ten years. Some keep their units longer than others but most replace theirs every decade. If you want to extend the life of your heater, check out these tips.


    • Keep your house well insulated: Insulation helps retain heat inside your home.
    • Keep your home dry: Moisture can cause problems with your heating system. It can lead to mold growth, rusting pipes, and more.
    • Use energy-efficient appliances: Energy-efficient appliances use less power than standard models. This energy efficiency reduces your utility bills.
    • Use weather stripping: Weather stripping seals gaps between windows and doors. Sealing these gaps prevents drafts that can damage your insulation.
    • Clean the ductwork regularly: Dirty ducts let outside air into your home. This leaking causes your furnace to work harder.
    • A dirty filter lets dust build up in your furnace: This buildup blocks airflow and increases fuel usage. Check the filter monthly.
    • Don’t overload your furnace: Too many people or pets can increase your electricity bill by using too much power.
    • Have a professional inspect your furnace: Have a professional inspect your furnace annually to ensure it operates safely.
  • How much does it cost to replace a furnace blower motor?

    A furnace blower motor replacement costs about $400-$600. You can save money by replacing the entire unit instead.

  • Can I install a new furnace myself?

    Yes, you can install a new furnace yourself. But if you’re uncomfortable doing this kind of project, hire a qualified technician.

  • Should I buy a new or used furnace?

    Buying a new furnace is often the best option. Used units may be cheaper, but they aren’t necessarily better. New units come with warranties and guarantees from manufacturers. They also tend to run quieter and perform better.

  • Is there anything else I need to know before calling Air Speed for furnace repair?
