When your furnace stops working or starts to malfunction, you must repair it immediately. There are numerous problems your system could suffer, and you must become familiar with the most common issues and warning signs.  

Blowing Cold Air  

Blowing cold air is a severe problem for a system to experience. In addition to causing your home to become unpleasantly cold, this problem may also indicate that significant repairs are needed. If your furnace suffers from this problem, you should check the thermostat first. Often, a thermostat can become dirty enough to prevent it from working correctly. If cleaning the thermostat does not correct the issue, this may indicate a problem with the unit's heating elements. Your furnace may have a mode that allows you to reset the furnace unit manually. Regretfully, if resetting the furnace fails to restore it, a professional will be needed. These services can comprehensively assess the furnace to determine the source of the lack of heat.

Yellow Burner Flame

The color of the burner flame may not seem like an essential factor, but it can reveal potential serious problems. For example, if the flame turns yellow, this may indicate that the furnace is producing carbon monoxide. Carbon monoxide is a grave threat to your health. This poisonous gas can be deadly in high concentrations and is odorless. These factors mean that individuals may not realize a problem until it is too late.

Possible causes of a yellow flame include a clogged burner or a dirty furnace. These accumulations can lead to fuel burning inefficiently. This inefficiency can increase the amount of carbon monoxide the system produces. Thoroughly cleaning the burner and pilot light may correct this problem. If this does not restore the flame to blue, the furnace should not be used until professional repairs are completed. Otherwise, you could expose yourself to hazardous amounts of carbon monoxide.

Mechanical Malfunctions

Many mechanical problems could develop with your furnace. These can range from faulty blower motors to worn-out bearings. For example, a broken blower motor can cause the furnace to overheat or shut down completely. Professional repairs are likely required if you suspect a mechanical issue with your furnace. Attempting to fix these issues yourself can lead to you making the problem significantly worse. Many mechanical issues can be challenging to repair without a deep knowledge of furnace systems. A professional will have the tools and expertise to diagnose and repair the problem that has impacted your unit.
