Your furnace is an essential part of your home.
During cold weather, you wouldn’t be able to stay warm without one.
However, furnaces can have some problems that are more common than others. Here are some reasons why your furnace won’t turn on. There may be a dirty air filter, an incorrect thermostat setting, a tripped circuit breaker, or the switch may be off. Repairing this problem can be complicated, so the price depends on what’s wrong. Your furnace follows a certain sequence when it begins heating your home. If something is wrong during the sequence, your furnace will shut off as a preventive measure. The issue may be caused by a dirty or malfunctioning flame sensor, a bad limit switch, an old thermostat, or a dirty air filter. Since these are estimates, yours may differ depending on the brand and model of your furnace. The cost of a flame sensor repair is $350-$500. A limit switch or thermostat repair can cost between $150-$350 while a furnace filter will only cost between $10-$30. If it’s extremely cold outside or you like your house to be warm, your furnace may be running for a long time. Make sure your thermostat is set correctly and is running properly if this isn’t what’s happening. Whenever the fan setting is at “on,” the blower motor will be running even when your furnace isn’t running, so it will sound like your furnace is always running. Alternatively, there might be a problem with the blower motor or your ductwork may be losing air, making your furnace run continuously to make up for the air loss. These costs are estimates, so it’s necessary to note yours may be different based on your furnace’s brand and model. A new blower motor can cost anywhere from $250-$800. To have your ductwork sealed, the cost varies based on the size of your home.
