What type of furnace should I purchase?

Furnace Types: Gas, Oil, or Electric

When considering a furnace replacement, choosing the same type that was previously installed will save you a lot of money. However, if you are getting a new installation, you have more flexibility and options.

Gas Furnace

Gas furnaces can cost more upfront to install, but they are more cost efficient to run. They heat up more quickly than electric, which adds to the running cost efficiency. Another benefit is that they are able to heat to hotter temperatures than an electric furnace for more comfort during cold Maryland winters.

Oil Furnace

Oil furnaces are also an efficient heating choice for more even heating in large areas. However, space is a consideration for the on-site oil tank. You will need to schedule oil deliveries to keep your tank stocked. Oil can cost more to run than electric, however, you have the flexibility of buying oil at the time of year the prices are lowest. Maintenance is also a cost consideration as the combustion process creates dirt and soot in your tank.

Electric Furnace

Electric furnaces are the cleanest and most quiet choice. Electric furnaces are generally less expensive to install, and require less maintenance than other options. However, electric furnaces take more time for the elements to heat than oil and gas, and therefore may be less cost efficient as this causes the unit to run longer.
