Heating System Not Working? Here's What Could Be Wrong

Not having ample heat during the cold Canadian winters can be a nightmare. Many people look forward to the winter festivities throughout the year. However, without a well-maintained and properly working heating system, these festivities can become the worst inconvenience. Imagine waking up on Christmas morning just to find out that your heating system has given up on you. The worst part is, many professional HVAC technicians do not work during the holiday season.

Hence, it is advised that you keep your heating system maintained and in good condition by scheduling regular checkups with an HVAC technician. However, if you have been avoiding maintenance for your heating system, and it has stopped working, there is a chance that one of its components has given up.

In some cases, minor issues can also lead to your heating system malfunctioning. However, if the system just shuts down, it is probably a major issue. In either case, it is important to narrow down what is causing the issue and fix it before it gets worse. In this blog, we have listed some of the issues that might be preventing your heating system from working efficiently or may be causing it to malfunction.

Common Problems With Heating Systems

Some of the most common problems that indicate relatively larger issues with your heating system are:

  • Your heating system keeps blowing hot air even after it has reached the required temperature
  • Some areas of your house are colder than the others
  • Cool air is coming out of the vents
  • The heating system light turns off on its own
  • Thermostat controls are not working
  • There is mold in the ducts and the system
  • There is a burning smell coming from the system

Issues With The Thermostat

If your heating system is overheating or under heating, it could indicate that your thermostat is malfunctioning or has been improperly set. Although it sounds like a no-brainer, programmable thermostats can be confusing and complicated. Hence, before deciding that your heating system is malfunctioning, it is better to see if your thermostat is set correctly.

In addition to this, there is a chance that the thermostat switch was moved around during cleaning or due to an impact. Hence, make sure everything is working properly before you decide to make some calls.

Your thermostat is responsible for regulating the amount of heat that is generated by your furnace as well as when that heat is generated. If you have an old thermostat that has been in service for more than a few years now, it is time for you to consider a programmable thermostat. It lets you choose different temperatures for various times of the day, night, and week. Moreover, these thermostats are much more energy efficient compared to their non-programmable options.

Dead Blower Capacitor

Chances are you have never seen the blower capacitor of your HVAC. It is a part of your furnace and looks like a big battery. This capacitor is responsible for starting your furnace when instructed by the thermostat.

Every capacitor has a tolerance level. If the tolerance level is lower than a specific level, your blower may not achieve the appropriate RPM. This may also indicate that your capacitor is dying or has already stopped working. The best way to deal with this problem is by replacing it.

Tripped Electrical Breakers

There is a chance that the furnace’s safety feature was activated and the electrical breaker was tripped. This can be easily fixed by resetting the tripped breaker. However, if the power keeps tripping off on your furnace, there might be an issue with the wiring of your HVAC system. It is best to call a licensed professional to see what the problem may be. A licensed HVAC technician can tell you if it’s a power supply or safety issue related to your heater. However, if it is a larger wiring issue, you might have to hire an electrician to deal with it.
