It’s the dreaded event that no one wants in the middle of winter: you wake up, and your vents are no longer providing heat to your home or business. It’s chilly inside, and you don’t know why. This scenario can happen in the Decatur, AL area and beyond.
Chances are, you rely on a furnace to heat your building, and you most likely use a gas furnace, as this is the most common type. However, furnaces of all types as well as boilers suffer from many of the same maladies that can cause no heating. So, what’s the cause of your heating issue?
Thermostat Issues. Thermostats tell your HVAC system when to turn on and off, and when this system goes on the fritz, you can end up with no heat. This is true with any system that relies on one.
Thermostats can break from use over time, or simply run out of battery life. First, check to see if your thermostat just needs new batteries. If the problem persists, you’ll need to call your local HVAC company to get the issue fixed. This may be a good time to upgrade to a smart thermostat to save some money, as you can program these to change the temperature in your home throughout the day.
Faulty Pilot Light or Ignition Control. These components control the ignition of your furnace, with pilot lights present in gas furnaces and ignition controls doing the job in other heating systems. Sometimes, it’s possible to reset your pilot light using instructions on your furnace, but you’ll need to call a professional if this doesn’t work, or if you have an ignition control instead.
Dirty Filters. A filter that’s dirty can cause air circulation problems. Though your furnace is turning on, air isn’t going through your vents very well. If this is the case, check your filters first, and change them out if they’re dirty or clogged with dust or pet hair. The good news is that this task is cheap and typically very easy to perform yourself.
A Bad Thermocouple. This component, when it goes out, can cause the no heat issue. They’re present in gas furnaces and heaters. This component keeps the pilot light lit when it heats properly, so if you’ve restarted the pilot light and it keeps going out, this may be to blame. Thermocouples can wear out over time, just like any other component in your furnace.
This is a relatively simple repair when done by a professional.
Dirty Flame Sensors. The inside of your furnace can get dirty over time, and this grime and buildup can coat the sensors used to keep burners going on and off properly. These components are found in furnaces that don’t have pilot lights.
Having a cleaning done on your furnace can easily solve this issue and get your heat working properly again.
Ductwork Issues. If you’re noticing a lack of heat to one part of your home, ductwork leaks may be to blame. The hot or cool air circulating through your home may not be reaching every room equally as it is leaking out somewhere else. It’s also possible there is an obstruction in one of your ducts, restricting airflow. Inspecting your ductwork or having a professional do so may help.
