What is a dual fuel HVAC system?

A dual fuel system combines an electric heat pump with a gas furnace. The heat pump handles heating efficiently in mild and moderately cold weather, and the furnace automatically takes over when temperatures drop to the coldest extremes. You get the efficiency of a heat pump with the power and reliability of gas heat.

The system automatically runs whichever heat source is most economical at any given temperature. For most of the season, the efficient heat pump does the work, and the gas furnace only runs when it's truly cold. This balance typically delivers the lowest possible heating bills for homes with gas available.

Dual fuel is an excellent fit for homes that already have gas heating and want lower bills without giving up cold-weather reliability. It's ideal for Maryland's mix of mild and freezing days. We'll assess your home and existing equipment and give you an honest recommendation.

Yes. A dual fuel system uses smart controls to monitor the outdoor temperature and automatically switch to whichever heat source is most efficient. You don't have to do anything — it manages the balance for you to keep your home comfortable and your bills low.

Cost depends on your existing equipment and the components needed. Because it's a system replacement or upgrade, we offer a free in-home estimate — so you get a clear, all-in price upfront, and we can point you toward any rebates or incentives you may qualify for.
