What is a Furnace Heating Coil?

What is a Furnace Heating Coil?

A furnace heating coil is a device that is used to heat air in furnaces. It works on the principle of convection, which means that it takes the cold air from outside and heats it up using heat generated by electric or gas-fired burners. The heated air then passes through the coils, which contain induction elements to transfer the energy from the furnace to the air. In this article, we will discuss how a furnace heating coil works and why it is important for maintaining a comfortable home environment. We will also look at what types of coils are available, as well as their advantages and disadvantages.

What is a furnace heating coil?

A furnace heating coil is a device that transfers heat from one medium to another. The most common type of furnace heating coil is the air-to-air type, which transfers heat from the hot gases in the furnace to the air that circulates through the home.

There are two types of air-to-air furnace heating coils: the primary and the secondary. The primary furnace heating coil is located in the furnace itself and heats the air that is circulated through the home. The secondary furnace heating coil is located in an air handler or blower unit and helps to distribute the heated air evenly throughout the home.

What are the benefits of a furnace heating coil?

There are many benefits of having a furnace heating coil. Some of these benefits include improved energy efficiency, increased comfort levels, and better air quality.

One of the main benefits of having a furnace heating coil is that it can help improve your home’s energy efficiency. When your furnace doesn’t have to work as hard to heat your home, it uses less energy, which can save you money on your utility bills. In addition, furnace coils can also help improve the overall comfort level in your home. By evenly distributing heat throughout your home, you can create a more comfortable environment for you and your family.

Finally, another great benefit of having a furnace heating coil is that it can help improve the air quality in your home. By circulating clean, fresh air throughout your home, you can help reduce the amount of dust and other allergens that can cause problems for people with allergies or asthma.

How does a furnace heating coil work?

A furnace heating coil is a metal coil that is placed in the furnace to heat the air. The coil is made of a material thatconducts heat well, such as copper or aluminum. The coil is heated by an electric current passing through it. As the coil heats up, it transfers heat to the air in the furnace. This heated air is then circulated through the house by the furnace’s blower.

How long does a furnace heating coil last?

A furnace heating coil typically lasts between 10 and 20 years. However, this lifespan can be shortened by factors such as excessive corrosion or overheating. If you notice your furnace coils beginning to fail, it’s important to have them replaced as soon as possible to avoid a complete system breakdown.

How much does a furnace heating coil cost?

The cost of a furnace heating coil will vary depending on the size and type of coil you need. A typical furnace heating coil can range in price from $300 to $1,200.


Furnace heating coils are an important component of your home’s HVAC system that helps to keep your house warm and comfortable during the colder months. They are a cost-effective way to maintain a consistent temperature in your home, but they need regular maintenance in order to work properly. If you suspect there is something wrong with yours, it is best to contact a professional as soon as possible so they can assess the situation and help you get back on track. With proper care, furnace heating coils can ensure that you have reliable heat all winter long.
