Reasons Your Furnace Is Blowing Cold Air

You might figure out why your furnace is no longer blowing out cold air, but let a professional Bryant tech further investigate the issue to be sure and provide the appropriate repair.

Some reasons that could explain why your furnace is blowing out cold air include the following:

  • You set your thermostat incorrectly.
    When your blower fan is set to Auto, it goes on when air is heated and ready to be distributed. If your thermostat is set to On, your blower fan will run continuously, even when your furnace is not producing heat.
     Change the setting to Auto and see if that helps. If this does not resolve the issue, your furnace is blowing out cold air for another reason.
     Maybe changing the setting worked—if this is the case, spare yourself future trouble and install a programmable or smart thermostat. Upgrading your thermostat to either of these will give you more control over the temperature of your home.
     A programmable thermostat lets you create a schedule for heating and cooling, while a smart thermostat can learn your heating and cooling preferences and adjust accordingly.
     Plus, you can reduce your energy use and cut down on your expenses by upgrading your thermostat. ENERGY STAR® reports you could save $50 a year on your energy costs with a smart thermostat.
  • You need to replace your air filter.
    When was the last time you replaced your disposable filter or cleaned your reusable filter? If you don’t change your filter according to the manufacturer’s recommendations, it can become clogged and prevent your furnace from working. Your heating system may be less efficient and incapable of keeping your home warm.
     Changing your filter will support optimal efficiency and improve your home’s indoor air quality (IAQ). If a dirty or clogged filter prevents your furnace from working correctly, replacing it should remedy the issue. Not sure if this is the reason your furnace isn’t working? You can leave it to a Bryant dealer who can determine the problem and offer you a solution.
  • Your ductwork is disconnected or damaged.
    If there are any leaks, tears, or loose connections in your air ducts, your heating system will not work efficiently. Warm air will escape through those areas rather than circulate throughout your home. A compromised airflow can cause different parts of your home to feel cooler than others.
     Browse our Bryant Colorado directory to locate a reliable HVAC dealer who can inspect and seal your ductwork if necessary.
  • Something is blocking your heat registers or vents.
    If blinds, curtains, or furniture are in front of your heat registers or vents, airflow may be restricted. When this happens, your furnace can overheat, eventually leading to a complete breakdown. Check to see if anything is obstructing your heat registers or vents, and move it.
  • The pilot light has gone out or there is another issue with your gas furnace.
    If you have a gas furnace, it may be blowing cold air out because the pilot light is out. It’s also possible there is an issue with the heat exchanger or another part or component. Just leave the repair to an experienced Bryant HVAC dealer.
     Is your furnace approaching the end of its service life? A well-maintained furnace could last 15 to 20 years, so if your furnace is around this age, it may be best to opt for a replacement. Discuss your options with a Bryant dealer today!
