Furnace Features That Help Protect Your Home

The first snow has fallen and the temperature has dropped to single digits. Furnaces and heating devices of all types will be running to keep your home comfortable and warm. If you're having a new gas furnace installed, it’s important to remember that with any gas installation comes the risk of overheating, gas leaks and carbon monoxide poisoning. Modern furnaces not only run more efficiently than ever before, but they also come equipped with advanced safety features that make these issues very rare. At Royal Heating& Air, we want to make sure when we install a furnace, you have all your questions answered. The best HVAC company at the Lake of the Ozarks has some of the key safety features that you will find in furnaces that help protect your home from any gas related issues. 

Limit Switch

The limit switch is programmed to switch off the furnace if it is at risk of overheating. Before the limit switch was installed, this would have meant an explosion, however, limit switches have kept this from becoming a fear. Some modern limit switches are combined with the fan switch, so if the fan failed to turn on, the furnace will not overheat.  

Air Pressure Switch

In newer furnaces, there is an additional blower that helps ventilate byproducts of combustion, such as carbon monoxide, away from the home and through the flue. If there is not enough air pressure moving through the flue, the unit will shut down as the air pressure switch signals the control board to do so. 

Flame Sensor

The flame sensor is one of the most important parts in preventing gas leaks. This sensor detects when there is no longer a flame at the burner, and shuts off the gas after a certain amount of time. In older furnaces, this was called the thermocouple. 


In older furnaces with traditional pilot lights, the thermocouple is a safety device that checks whether or not the pilot light is burning properly. The thermocouple is connected to the gas valve that leads to the pilot light and has a sensor that detects heat from the burning flame. If the flame goes out or is burning weakly, the thermocouple shuts off the gas supply to the pilot light in order to prevent gas from leaking into other parts of your furnace. 

Carbon Monoxide Detectors

Although carbon monoxide detectors are not part of your furnace, they're closely linked to the safety of your furnace, because they warn you if your system has a carbon monoxide leak. Bryant Heating & Cooling Systems offers an alarm that uses sophisticated electronics and unmated sensor technology to detect the CO levels in your home. 

Keeping You Warm & Safe 

At RoyalHeating & Air, our goal is to keep you warm all winter long. However, when it comes to running a gas furnace, there are risks of overheating and gas leaks.
