One of the most important things to consider when choosing a furnace is the fuel type. All furnaces generate heat by consuming fuel. While some furnaces run on natural gas, though, others run on electricity. Aside from using different types of fuel, there are several key differences between gas and electric furnaces.
#1) Heating Speed
Gas furnaces are typically faster than electric furnaces. They can heat the homes in which they are used more quickly. They will burn natural gas and air to produce hot combustion gases. Regardless, you can use a gas furnace to quickly heat your home.
#2) Efficiency
Different furnaces have different efficiency ratings. You can refer to a furnace’s Annual Fuel Utilization Efficiency (AFUE) rating for insight into its efficiency. Bu gas furnaces – especially condensing gas furnaces – are oftentimes more efficient than electric furnaces. They will convert more of their fuel (gas) into heat.
#3) Noise
Another difference between gas and electric furnaces is the noise. Neither gas nor electric furnaces are completely silent. They will both produce at least some noise during use. Electric furnaces, however, typically have a quieter operation than gas furnaces.
#4) Installation
Electric furnaces are easier to install than gas furnaces. You should always get new heating, ventilation and cooling (HVAC) equipment installed by a professional technician. Since they only run on electricity, though, electric furnaces are easier to install. Technicians don’t have to connect them to a gas supply line, nor do they have to set up an exhaust system for the flue gases. As a result, many technicians charge lower prices for electric furnace installation services.
#5) Maintenance
Both gas and electric furnaces require maintenance. You’ll need to change the air filter once every few months, and you should get them professionally inspected at least once a year. If you choose a gas furnace, you’ll also need to install and maintain carbon monoxide (CO) detectors in your home. If the heat exchanger cracks, CO may leak out of the gas furnace and into your home.
#6) Heating Power
Gas furnaces typically offer more heating power than electric furnaces. They can produce more heat thanks to their use of combustion. In Georgia and the surrounding Southeast, an electric furnace will typically suffice. Even in the middle of winter, a high-quality electric furnace will produce more than enough heat to create a comfortable living space. But homeowners who live in cooler regions may want to choose a gas furnace, instead.
