Fall is upon us! The season of pumpkins, colorful leaves falling off trees, and of course, Jack Frost making his appearance. Now is the perfect time to start winterizing your home. Nothing is more important when preparing for Washington’s long winters than your home heating system.

If that old furnace is getting rusty, it may be time to look for a new one. Yes, it’s overwhelming researching whether to go gas or electric, and thinking about shelling out all of the money. But if your furnace is an energy hog, you may find your monthly savings pay for the furnace sooner than you think. So before you decide on a new heating system for your home, get all the facts on gas and electric furnaces.

Gas Furnace Pros

Efficiency Saves You Money

Gas furnaces are the most efficient available. They use less fuel, and heat homes faster than electric, and will cost you significantly less each month as a result.

Heats Fast, Burns Comfortably

Because gas burns at a high temperature, it heats up fast, and is more effective at heating the whole house. Gas also heats in a manner that most users consider to feel slightly less dry, and more comfortable than electric furnaces.

Gas Furnace Cons

Expensive to Buy and Install

Gas furnaces are significantly more expensive to buy and install than electric furnaces.


Part of the install expense is due to gas furnaces size. They are much larger than electric furnaces.

Require Ventilation/Maintenance

Burning gas creates CO2, which needs to be ventilated to be burned indoors. So gas furnaces require intense ventilation systems. Electric furnaces don’t require any ventilation. These vents must also be maintained, which costs money,

Electric Furnace Pros

Less Expensive to Buy and Install

Electric furnaces are smaller, and don’t require ventilation, so they are much easier, and less expensive to purchase and install.


Electric furnaces don’t make the clicks and pops that gas furnaces sometimes emit.

Easier Maintenance, Longer Life

With no ventilation, and simple small designs, electric heaters don’t require much maintenance. They also last longer than gas furnaces by quite a few years.

Electric Furnace Cons

Less Efficient, Don’t Get as Hot.

Electric furnaces are less efficient. This results in lower household temperatures during extremely cold temperatures. When you need them most, when it’s really cold, electric furnaces just don’t get that hot.

More Expensive by Month

As anyone who pays an electricity bill knows, that stuff isn’t cheap! Electric furnaces are the main electricity hog during winter months, driving those bills up much higher than natural gas.
