Your furnace is a key part of your home. Without one, you wouldn\u2019t be able to stay warm during the winter. Yet furnaces can have some problems that are more common than others.<\/p>\n\n\n\n

Let\u2019s review these problems and discuss what they might cost to correct so you know before you contact an HVAC technician. Some of the most common\u202ffurnace repair\u202fproblems involve:<\/p>\n\n\n\n

  • Furnace won\u2019t turn on<\/li>
  • Furnace doesn\u2019t stay lit<\/li>
  • Furnace won\u2019t blow hot air<\/li>
  • Furnace won\u2019t turn off<\/li><\/ul>\n\n\n\n

    1. The Furnace Will Not Turn On<\/h2>\n\n\n\n

    There are a couple of reasons why your furnace won\u2019t turn on, so make sure to go through all of them.<\/p>\n\n\n\n

    • Is your thermostat set correctly?\u202fMake sure it\u2019s set to \u201cheat,\u201d \u201cauto\u201d and that your desired temperature is greater than the room\u2019s current temperature. If you have a programmable thermostat, make sure it has new batteries.<\/li>
    • Is the circuit breaker tripped?\u202fYour furnace can\u2019t operate if it doesn\u2019t have power. Reset the switch if it\u2019s facing the outside of the electrical panel.<\/li>
    • Is the furnace switch off?\u202fYour furnace has a power switch found on or near it. Since this switch looks like a light switch, it\u2019s easy to accidentally turn it off. If it was off, it might take your furnace a few minutes to turn on.<\/li>
    • Is the air filter clean?\u202fA dirty air filter can create a lot of problems for your furnace. Replace yours if you can\u2019t see light through it.<\/li><\/ul>\n\n\n\n

      Estimated Repair Cost<\/h3>\n\n\n\n

      This issue can be complicated, so the estimated cost to repair it depends on what\u2019s wrong.<\/p>\n\n\n\n

      2. The Furnace Ignition System Isn\u2019t Working<\/h2>\n\n\n\n

      Your furnace uses a certain sequence when it starts heating your home.<\/p>\n\n\n\n

      • Your thermostat detects the temperature has fallen and tells your furnace to start running.<\/li>
      • The draft inducer fan activates to bring in fresh air for combustion.<\/li>
      • The gas valve unlocks for the burners, which are lit electronically.<\/li>
      • The flame sensor signals to your furnace the burners have been ignited.<\/li><\/ul>\n\n\n\n

        If something is off during the sequence, your furnace will shut down as a safety precaution.<\/p>\n\n\n\n

        A couple of potential causes for this issue include:<\/p>\n\n\n\n

        • Dirty or malfunctioning flame sensor. If the sensor doesn\u2019t detect a flame, it will shut off your furnace to keep natural gas from getting into your home. The ignition process corrodes flame sensors over time. While cleaning during annual\u202ffurnace maintenance\u202fcan help, yours may ultimately need to be taken out and changed.<\/li>
        • Bad limit switch. This safety feature will turn off your furnace if it detects backdrafting. Backdrafting is dangerous, because carbon monoxide and natural gas can leak into your home. These switches can fail due to age, damage or dust buildup.<\/li>
        • Old thermostat. If your thermostat isn\u2019t working properly, your furnace won\u2019t be able to operate.<\/li>
        • Dirty air filter. A dirty air filter can limit airflow and force your furnace to shut down to avoid overheating. Make sure to replace yours every 30 to 90 days, or anytime you can\u2019t see light through it.<\/li><\/ul>\n\n\n\n

          Estimated Repair Cost<\/h3>\n\n\n\n

          These costs are estimates, so it\u2019s important to note yours may fluctuate based on your furnace\u2019s brand and model.<\/p>\n\n\n\n

          • Flame sensor: $350\u2013$500<\/li>
          • Limit switch: $150\u2013$300<\/li>
          • Thermostat: $150\u2013$350<\/li>
          • Furnace filter: $10-$30<\/li><\/ul>\n\n\n\n

            3. My Furnace Blows Cold Air<\/h2>\n\n\n\n

            In many cases, this problem is linked to a wrong thermostat setting or a dusty air filter that\u2019s limiting airflow. Follow the steps above to fix the problem.<\/p>\n\n\n\n

            4. The Furnace Isn\u2019t Shutting Off<\/h2>\n\n\n\n

            If it\u2019s very chilly outside or you like your home to be toasty, your furnace may be working for a long time.<\/p>\n\n\n\n

            If this isn\u2019t the case, ensure your thermostat is set correctly and working properly. If your fan setting is at \u201con,\u201d the blower motor will be going even when the furnace isn\u2019t, so it\u2019ll seem like your furnace is on all the time.<\/p>\n\n\n\n

            Alternatively, there might be an issue with the blower motor or your ductwork may be losing air, forcing your furnace to run continuously to make up for the lost air.<\/p>\n\n\n\n

            Estimated Repair Cost<\/h3>\n\n\n\n

            These costs are estimates, so it\u2019s important to note yours may vary based on your furnace\u2019s brand and model.<\/p>\n\n\n\n

            • New blower motor: $250\u2013$800<\/li>
            • Seal ductwork: varies based on square footage<\/li><\/ul>\n\n\n\n
