    Furnace Repair Dallas: The Furnace Won’t Turn On

    There can be many reasons why your furnace won’t turn on, leaving you in need of furnace repair. Dallas homeowners should be aware of some of the possible causes of a furnace that won’t turn on, including:

    • The circuit breaker is off: You may not have an electric furnace, but even if it runs on gas or propane, there are still parts of your furnace that use electricity. The first step in troubleshooting a furnace that won’t turn on is to ensure all the HVAC switches on your circuit breaker panel are turned on. If you're still facing issues, you may need to call in a professional for furnace repair in Dallas.
    • The thermostat is faulty: Another issue that could be behind your Dallas furnace repairs is a faulty thermostat. You’ll want to check your thermostat if your furnace won’t turn on. It may be that the thermostat is broken or needs to be reset. To check your thermostat, set it to heat and then increase the temperature to 10 degrees hotter than usual. This should make the system kick in. If it doesn’t, then you may need furnace repair. Dallas professionals can help there.
    • The air filter is dirty: Over time, your thermostat collects dust and allergens from the air. If you’ve not changed the air filter in your furnace in a while, it may have become very clogged. In some furnaces, a severely clogged air filter will trigger a safety feature that will prevent the furnace from turning on, leaving you in need of furnace repair. Dallas experts are well-practiced at fixing all kinds of filter clog issues.
    • The pilot light has gone out: The pilot light is key to a properly functioning furnace. If it has gone out, then the furnace won’t turn on—this is also a safety feature. Without a pilot light, if the furnace stayed on, it would pump dangerous gas into your home, leaving you in need of furnace repair in Dallas. If it's gone out, you'll want to enlist the help of a Dallas furnace repair expert.
    • There is a lack of natural gas or oil supply: Similar to how your car needs gas to run, so does your furnace. If you have a natural gas or propane furnace that won’t turn on, it may not be receiving enough fuel. If the furnace runs on natural gas, and you also have a natural gas stove, you can turn on the stove to see if the problem is with the gas supply or with the furnace alone. If neither is working, you should contact your energy company as soon as possible or call us for furnace repair in Dallas.

Furnace Repair Dallas: The Furnace Won’t Turn Off

If you’re having the opposite problem and your furnace won’t turn off, causing the need for furnace repair, Dallas residents should be aware that it could be due to the following factors:

  • The thermostat is faulty: Similar to how a malfunctioning thermostat could prevent your furnace from turning on, it can also stop it from turning off. Possibly, the wiring that communicates to your furnace has worn out, so the furnace doesn’t realize your home has reached the right temperature, leaving you in need of Dallas furnace repair. Alternatively, your thermostat settings might be incorrect. For example, the thermostat may have been left on “on.” This will tell the furnace to run continuously. Switch your settings to “auto.” This will tell the furnace to turn off once your home is warmed. If this doesn't work, you may need to call in our help for furnace repair in Dallas.
  • The air filter is dirty: Another cause of your furnace repair, Dallas residents, could be due to a dirty air filter. A furnace with a dirty air filter may run continually if it doesn’t have the safety feature of shutting down due to a dirty filter. This is because the congested filter forces your furnace to work hard to heat your home. As the furnace is less efficient, it has to run longer to get your home to the set temperature.
  • The ductwork is leaking: Your ductwork is what moves hot air through your house. If there is a break in the ductwork and the hot air leaks out, then your home will not be heated efficiently, and you may find yourself in need of furnace repair. Dallas homeowners can trust our team to remedy their home, ensuring their ductwork is sealed and running efficiently.
  • The blower fan motor is broken: The blower fan forces hot air into the ductwork, where it moves through your home. If there is a problem with the blower fan motor, the furnace may fail to stop running, which may be the cause of your need for furnace repair in Dallas. A malfunctioning blower fan motor is typically due to a broken fan limit switch. The fan limit switch is what triggers the motor to turn “off.”

Furnace Repair Dallas: The Pilot Light is Out

Your pilot light going out may be the root cause behind your Dallas furnace repair. Generally, there are a couple of reasons why your furnace’s pilot light might go out.

  • The thermocouple is malfunctioning: The thermocouple’s job is to deactivate the gas in your furnace when the pilot light turns off. If your furnace did not have a thermocouple, natural gas would leak into your home, leaving you in need of Dallas furnace repair. If the thermocouple can’t detect the flame in your furnace—for instance, if it’s broken or covered in dust—it will shut off the natural gas supply and inhibit the pilot light, and you'll want to call in expert professionals for furnace repair. Dallas homes will be back up and running in no time.
  • The pilot light has blown out: Like a candle, sometimes a breeze or draft in your home can blow out the pilot light, and before you know it, you need furnace repair. Dallas residents — even if you think this is why your pilot light has been extinguished, it’s still safer to call the Dallas repair professionals at Aire Serv to check. Our skillful pros will be able to see if there is an underlying problem that caused the pilot light to go out when it comes to your Dallas furnace repair. Our friendly and capable experts can be reached easily on the phone or online.
