Common Causes of No Heat Calls, and What to Do Next

With the chilly weather comes the “No Heat Calls”- calls where people report losing heat. This issue can happen to anyone and is not only inconvenient, it is also dangerous. Although modern heating and cooling systems are generally reliable, they can still develop problems that threaten safety and comfort. 

Thankfully, there are ways that you can reduce the frequency of issues with your heating system, and if something does go wrong, we are here to help. 

Let’s take a look at some common causes of no heat calls, and what you should do if they happen! 

Lack of Heating Maintenance

Often, we get calls about furnaces that are simply not turning on. Correcting the problem can be as simple as throwing a switch, but this often occurs because sensitive parts of the furnace system have become dirty during the time it wasn’t being used. Dirty burners, dirty flame sensors, dirty blowers, and dirty air filters can all cause a heating failure. To avoid these issues, make sure you have an HVAC technician over for yearly maintenance. If this issue does occur, a technician can clean out the affected areas and get things running properly with only minor maintenance! 

Ductwork Issues

Sometimes, the problem isn’t with the heater itself, rather it is with the ductwork- for example: dirty, kinked, or leaking ductwork. This can cause long term airflow problems which over time, can cause the system to overheat and break down. When this happens, you need to have an HVAC technician fix the broken parts of the heating system, and redo the problematic ductwork to prevent the issue from repeating itself.

A Dead Blower Capacitor

The blower capacitor is the “big battery” part that starts the furnace when the thermometer instructs it to. Thankfully, this is usually a simple issue to resolve, as the blower capacitor just needs to be replaced with a short visit by our qualified technicians. 

Thermostat Issues 

If your thermostat is malfunctioning or working improperly, your heater may not turn on.  Newer thermostats come with lots of programmable options that can get mixed up and mimic malfunction, so sometimes repair is not needed and correcting the problem is as simple as reprogramming the thermostat. If not, a malfunctioning thermostat can be fixed or replaced quickly by an HVAC technician. 

Although there can be other reasons for “No Heat Calls”, these are some of the most common. Once you know what is happening, most things can be easily fixed. Even if you don’t know what the issue is with your heating system, you can rest assured that our technicians have got you covered.
