Heat pumps are significantly more energy-efficient when associated with a gas furnace. The installation cost of a heat pump usually takes less than a gas furnace. Furnaces need an expanded ventilation system.
The Performing cost depends on the electricity rates of that area which are mostly lower than natural gas so a heat pump will cost less than a gas furnace.
The heat pump system needs indoor and outdoor elements to compare to a gas furnace that just has an indoor component.
In an extremely cold climate, a heat pump is not as efficient for heating a house.
The benefits of a gas furnace for a home heating system include:
A gas furnace has fewer mechanical components than a heat pump, indicating less parts can break down or failure. A gas furnace flaming can occur in more polluted air and reduced indoor air quality in the house.
A gas furnace normally has a greater lifespan compared to a heat pump and because it just works for a few months during a year, the maintenance of it is easier and less costly.
