If you have an old furnace in your home, you might be wondering how to detect when it’s starting to break down. Besides, you want to know as early as possible, so you can get in touch with a technician and have a professional fix your heating system right away. These are some things to keep in mind. 



  • Age: It should come as no surprise that the older your furnace, the more likely it is it will stop working sooner rather than later. When it does, you can hire a heating, ventilation, and air conditioning (HVAC) company to repair it for you. Or if you want to replace your furnace, you can purchase a new one and call a professional technician to install it for you. At Air In Motion, we can assist you in setting up or fixing your heating systems. 
  • Dust: Make sure you change the filter of your furnace every few months, so that your furnace can filter the air it distributes. However, if you begin to notice that there is an increased amount of dust being accumulated in your home, you might need to call an HVAC company to take a look at your furnace. 
  • Light: With natural gas furnaces, the light should be blue and not yellow. If you notice a yellow light, turn off your furnace and get in touch with a technician. A yellow light is a sign that your furnace is clogged with dirt since the amount of oxygen is being restricted. If the light goes out, that is also an indication that something is wrong with your furnace. 
  • Air: Your furnace should heat your home. If it’s not, that’s a sign your furnace isn’t working. Check to see if there are cold areas in your house as a result of your furnace not being able to distribute hot air. A technician will be able to identify any problems with your furnace, such as if there’s a problem with the fan blower. Something else to pay attention to is if you’re using your furnace the same way but your heating bill goes up all of a sudden. As furnaces get older and become less efficient, they will use up more energy to maintain the same temperature in your home. 
  • Noise: Another sign that your furnace needs to be repaired or replaced is if you start to hear noises coming from it that you haven’t heard before. In some cases, parts inside your furnace may have come loose, and that’s why you’re hearing a noise.
