3 Main Types of Furnaces

Furnaces are one of the best ways to keep your home warm and cozy during the colder months. While heat pumps can offer efficient heating and cooling, if the temperature drops low, furnaces offer the best heating capabilities. Furnaces work by using energy to create heat, then distribute the heat through your home by blowing warmed air through vents and ducts. While all furnaces basically work the same, there are differences in energy types. Here are the three main types of furnaces and the differences in costs and efficiency.

Natural Gas

If natural gas is available, most people prefer natural gas furnaces for heating. Gas offers even, comfortable heat and is less expensive than most other types of energy. The main drawback of gas furnaces is the minute possibility of a leak, which can be very dangerous. It is important to have a C02 detector in the home as a safety precaution.


While the least common furnace, oil is used for furnaces and can offer effective heating. Oil furnaces are most common in colder regions, especially where natural gas is not easily available for all homes. Oil is more expensive than natural gas, resulting in higher energy costs.


Smaller and less expensive to purchase, electric furnaces can be a good option in some circumstances. They are less efficient and tend to cost more to heat a home than natural gas, but their lower initial cost and smaller size is desirable for some homeowners.
