Get to Know Your Electric Furnace.

As the earth’s climate continues to fluctuate, owning an electric furnace can be your best financial decision. You will provide a warm and safe haven for yourself and your family. With a framework of metal-based heating parts, the electric furnace does its job when electricity runs through it.

The metal coils generate heat after they become hot and transfer it to the air revolving in the electric furnace. Since hot air rises and displaces cold air, it forms air currents that run through your house, making it warm.

With its electrical contraption, the temperature in your house is easily adjusted once you touch the thermostat. If the temperature is below the threshold you have set, then the machine generates heat. The process occurs in stages, which is good for energy consumption and saving features.

As its metal coils are heated, the appliance’s blower motor is turned on and sucks in cold air, which is heated and then rotated back to the house.

Why Your Electric Furnace is Blowing Cold Air.

The first reason why your electric furnace is blowing cold air is because it has thermostat problems. This is the most obvious problem; you should check whether you have set the correct settings before using it.

Other times, the battery may have expired, or the technology used in your thermostat may not be up to standard. Therefore, it is wise to check whether the thermostat has been set to “heat”; if not, change it.

You could consider upgrading the device to a new model with the latest technology or switching out the batteries.

The second reason your electric furnace blows cold air is that your house’s circuit breaks, and the power supply have malfunctioned. Given their reliance on electricity, this could be a common problem in your home.

The moment your power supply is unstable, or the circuit breaker has been tripped, you are in for a cold night. To fix this, you could set your electric furnace on its own circuit to ensure it does not overload. Also, you could reset any breakers that have been tripped.

In more complex situations, you could call your electrician and have them examine your home’s electrical system to ensure that it is compatible with the energy needs of the electric furnace.

The third problem you should watch out for if your electric furnace is emitting cold air is its air filters. As explained earlier, the air filter system is critical in ensuring that cold air is sucked inefficiently as hot air is pushed out.

With the filters constantly interacting with debris and dust, they can inevitably be clogged and restrict airflow. As a result, the electric furnace finds it difficult to emit cold air. Therefore, at this point, checking whether you have dirty filters is necessary to mitigate this problem effectively.

The fourth reason your electric furnace is blowing cold air is its heating element malfunctioning. This system is the core of all activities the electric furnace is expected to perform. Wear and tear issues are possible and may cause some, if not all, of the elements of the heating system to fail.

As a result, your electric furnace will be unable to generate the heated air it is supposed to. This problem, however, is too complex for the simple patchwork you imagine you can perform. It is highly advisable that you contact a professional and let them fix the issue.

This will prevent any accidents or injuries that may lead to even higher costs and discomfort and let uou enjoy the services of your electric furnace.

Finally, your blower motor and fan may be compromised if your electric furnace is emitting cold air. The fan could be obstructed by objects, or the motor could be malfunctioning.

In other situations, the bearings and belts in the system may be worn out and unable to achieve the smooth running needed to blow hot air in your house.

This problem also requires a professional technician who will make the relevant changes to ensure you are back in that comfort zone in your home.

Finally, if your electric furnace has constant problems, be sure to call a professional HVAC technician who will ensure you remain comfortable in your home. While this may feel like an expensive venture, it is worth the time and energy you save trying to figure out how to fix your electric furnace when it is blowing cold air.
