If you’re looking for year-round savings, you might want to consider a dual fuel heating system. Since electric rates are regulated and constantly monitored by the government, investing in a dual fuel furnace now totally makes sense.

Marsh Heating and Air Conditioning is your trusted heating company in Crystal, MN that carries a wide variety of furnaces, including models that have dual fuel capability.

What is a Dual Fuel System?

Also known as a hybrid system, a dual fuel system is the combination of a gas or oil furnace and a heat pump, which works both as a heater and a cooler. By combining the efficiency of a heat pump during its peak efficiency with a high-efficiency gas furnace, a dual fuel system provides maximum efficiency, energy savings, and improved comfort levels.


A dual fuel system offers you at least two stages of heat. Did you know that even when it feels cold outside, there is still a good amount of heat waiting to be pumped? When the temperature is above 35 degrees or so, a heat pump can pull heat from the outside air for much less compared to firing up a furnace. The furnace will only kick in during the cold months. Heat pumps save energy for the simple reason that they only transfer heat instead of producing it. In ideal situations, a heat pump can transfer up to three times more energy than it consumes. On the other hand, a high-efficiency gas furnace is at most 98 percent energy-efficient.

Dual fuel heating gives you the opportunity to add a secondary heating system to your existing one. It also is an efficient alternative to unstable fuel prices.

Who Should Consider Getting a Dual Fuel System?

If you already have a heat pump and want to add a high-efficiency gas furnace into the mix, getting a dual fuel system will give you the most benefits. Your gas furnace will act as the main heater using the heat pump’s electric strip only when the temperatures are very low.

If you have a working heat pump and an air conditioner that needs a replacement, you can opt to get a dual fuel furnace. When your air conditioner fails, you can still use your heat pump to act as your cooler, and your dual fuel furnace as your heater, especially during the cold months of winter.
