It really depends on you.
I was pretty surprised when I first learned about dual-fuel HVAC systems. The whole idea of a combination of different fuel sources is actually brilliant and it really shows the hard work and dedication that HVAC engineers have supplied over the years to bring us this marvelous HVAC technology. Basically you have a heat pump working along with a furnace so that your system can provide the best efficiency depending on the season. In the warm season, the electric heat pump will work to provide the cooling that is needed for your home. Heat pumps are fantastic for the warmer months and you’ll definitely appreciate the energy efficiency. Even when the temperatures start dropping towards the end of the fall season, the heat pump will provide highly efficient heating that will keep your energy bills low. As you dip down past the 40s however, the furnace will then crank on. You can have your choice between a gas, electric, or oil furnace. It really depends on you. If you live in a place where you have no access to utilities, you might want to opt for an oil furnace or electric with solar panels. Going all electric is a smart move if you have solar panels, but you’ll have to be weary of too much energy use. With a solar panel HVAC system, you’ll definitely need back up sources of heating and it’s smart to have a fireplace for the winter weather. But the dual-fuel HVAC is a great modern choice when it comes to highly energy efficient HVAC systems.
