Electric furnaces are the main alternative to gas-based systems, using electricity to generate heat. They are often used in tandem with a heat pump, particularly in warmer climates, where they can provide sufficient heating without the need for a furnace. However, electric furnaces have received criticism due to their high operating costs, with some recommending natural gas furnaces as a cheaper alternative. Nevertheless, electric furnaces remain a viable option, especially in areas with high gas prices or for those seeking to avoid the potential safety risks associated with gas furnaces, such as gas leaks.
| Characteristics | Values |
|---|---|
| Electric furnaces became popular | In places with limited access to gas lines, electric furnaces were a viable option. |
| Compared to gas furnaces | Electric furnaces are less efficient, worse for the environment, and require more maintenance. |

What You'll Learn
Electric furnaces are an alternative to gas-based systems
However, electric furnaces tend to be more expensive to run than gas furnaces, as gas is cheaper than electricity. Gas furnaces are therefore better suited to colder climates, as they can generate higher temperatures and heat a home faster. Electric furnaces, on the other hand, are more commonly used in warmer climates, as they are typically sufficient to heat homes during mild winters.
The decision between an electric or gas furnace will depend on a variety of factors, including the climate, the heating and cooling needs of the home, and fuel pricing and availability in the area. For example, in very warm climates, an air handler may be used in conjunction with an air conditioner, without the need for a furnace.
In terms of cost, electric furnaces tend to be cheaper to install, as they do not require venting systems or gas hookups. However, gas furnaces have lower operating costs, and the overall cost of running a gas furnace is lower than that of an electric furnace.
Both types of furnaces require regular maintenance, but gas furnaces require more standard maintenance, increasing costs. Electric furnaces are also generally considered safer, as gas furnaces pose a risk of carbon monoxide leaks, particularly in large buildings.

They can work with modern cooling systems
Electric furnaces are the main alternative to gas-based systems. They use electricity to generate heat. Electric furnaces can work with modern cooling systems, but they are generally less efficient and worse for the environment than many modern systems.
Electric furnaces can work in tandem with a modern cooling system, such as a heat pump, or in places where there is a lack of access to a gas line. They are still found in many older homes and represent an alternative to gas furnaces, which were historically much more expensive.
However, electric furnaces tend to be less efficient than modern systems. They require frequent maintenance due to the volatility of the oil, which can easily become contaminated and harm the system.
Air handlers are another option for heating and cooling homes. They distribute both warm and cool air, whereas furnaces only provide heating. Air handlers rely on a separate heat source, such as a heat pump, to deliver heated air. They are more energy-efficient and have lower operating costs than furnaces.
The decision between an electric furnace and an air handler depends on various factors, including climate, energy costs, and budget.

They require frequent maintenance
Electric furnaces have become less popular due to their frequent maintenance needs and high operating costs. They are also dirtier, worse for the environment, and less efficient than modern systems.
The volatility of the oil used in electric furnaces means that it can easily become contaminated and harm the system. This requires regular maintenance visits, which can be costly and inconvenient.
In addition, electric furnaces may not provide sufficient heating in very cold climates. They may also require supplemental heating sources, such as gas furnaces or electric strips, to maintain comfortable temperatures.
The operating costs of electric furnaces can be very expensive, especially if they use all-electric resistance heating strips. While electric heat is said to be 100% efficient, the high electric rates can result in significant expenses for homeowners.
Furthermore, switching from a gas furnace to an electric furnace may require additional expenses, as the home may need new lines to properly fuel the system.
Overall, the frequent maintenance needs of electric furnaces, combined with their potential ineffectiveness in cold climates and high operating costs, have contributed to their decline in popularity. Homeowners often prefer alternative heating systems that offer better energy efficiency, lower maintenance requirements, and more cost-effective solutions.

Air handlers distribute heat, they don't generate it
Electric furnaces are the main alternative to gas-based heating systems. They use electricity to generate heat, and are often found in older homes. However, they tend to be less efficient and worse for the environment than modern systems.
Air handlers, on the other hand, do not generate heat. They are a component of an HVAC system, responsible for circulating conditioned air throughout a home. They work in tandem with other HVAC components, such as a furnace, air conditioner, or heat pump, to ensure that air is properly filtered, conditioned, and distributed.
While air handlers do not generate heat, they can include a heating element or coil, which allows them to warm the air before distributing it. They are particularly useful for homes with heat pumps, as heat pumps do not have a built-in blower and rely on an air handler to distribute heated or cooled air. In warmer climates, a heat pump and air handler system can be a more energy-efficient solution than a furnace, as they transport heat from outside into the home, which the air handler then distributes.
Air handlers are controlled by a thermostat, ensuring a consistent and comfortable temperature. They can also help to control indoor humidity levels and improve indoor air quality. They are typically located indoors and connected to ductwork that runs throughout the home.

Air handlers are more versatile than furnaces
Air handlers and furnaces can serve the same function of heating homes, but they have some key differences. Furnaces are a popular choice for heating homes, especially in colder climates. They use fuel sources such as natural gas, oil, propane, or electricity to generate heat. On the other hand, air handlers do not generate heat directly but distribute the heat produced by a separate appliance, such as a heat pump. They are more versatile than furnaces because they can handle both heating and cooling, making them suitable for year-round use.
The versatility of air handlers lies in their ability to distribute both warm and cool air, unlike furnaces that are exclusively for heating. In warm climates, an air handler can often provide sufficient heating without the need for a furnace. For example, in Florida's mild winters, an air handler can efficiently heat homes. Additionally, air handlers can help control indoor humidity levels, contributing to improved indoor air quality and comfort. They often include filters and coils that affect indoor air temperature and humidity.
While furnaces are reliable during colder months, their usage is limited to heat production. They are most effective in extremely cold temperatures and are a complete device for generating, warming, and distributing air. Furnaces come with a dedicated blower fan that pushes heated air through ducts when the thermostat calls for heating. However, their reliance on fossil fuels makes them less environmentally friendly than air handlers.
Air handlers, when paired with heat pumps, create a more effective and efficient system. While the initial cost of installing an air handler with a heat pump is higher, the long-term benefits include energy efficiency and lower operating costs. This combination is ideal for moderately cold areas but may not be sufficient for extremely cold regions.
In summary, air handlers offer the advantage of year-round functionality, providing both heating and cooling capabilities. Their ability to maintain comfortable temperatures and improve indoor air quality makes them a versatile choice for homeowners. However, furnaces remain a popular option for regions with extremely cold winters, as they offer reliable heating performance even in harsh conditions.
