Heat Pumps vs. Gas Furnaces
Choosing the Right Heating Solution for Your South Denver Home

If you’re evaluating a new heating system, you’ve likely asked the same question many South Denver homeowners are asking today: Should I install a heat pump or stick with a gas furnace? The right answer depends on your home, comfort goals, and long-term energy priorities.
Since 1973, Southwest Heating & Cooling has been the trusted HVAC partner for homeowners in Littleton, Highlands Ranch, Centennial, Castle Rock, Lakewood, and throughout the entire South Denver Metro area. With more than 50 years of local expertise and a customer-first approach, we help homeowners understand the real-world differences between heat pumps and gas furnaces—so they can choose confidently.
The Core Difference: How They Heat Your Home
Gas Furnaces
Gas furnaces create heat by burning natural gas and distributing warm air through ductwork. They’ve been a common choice in Colorado for decades and can deliver strong heat during cold weather.
Heat Pumps
Heat pumps don’t create heat—they move heat. In winter, a heat pump extracts warmth from the outdoor air and transfers it inside. In summer, it reverses direction to provide cooling. This makes heat pumps complete heating and cooling systems, not just an alternative to air conditioning.
Performance in Colorado’s Climate
Modern cold-climate heat pumps are specifically designed to perform in freezing temperatures, making them a reliable option for South Denver winters. When properly selected and installed, they deliver steady, efficient heat during most winter conditions.
Some homeowners choose a hybrid or dual-fuel system, combining a heat pump with a gas furnace. This approach allows the heat pump to handle everyday heating and cooling, while the furnace provides backup during extreme cold.
Comparing Heat Pumps and Gas Furnaces
Energy Efficiency
Heat pumps are among the most energy-efficient HVAC systems available. Because they transfer heat instead of generating it, they often use significantly less energy than gas furnaces.
Heating and Cooling
Gas furnaces only heat. Heat pumps provide both heating and cooling in one system, potentially replacing both your furnace and air conditioner.
Operating Costs
Many homeowners see lower overall energy costs with heat pumps, especially when replacing older, inefficient systems.
Environmental Impact
Heat pumps reduce reliance on fossil fuels and can be paired with renewable electricity, supporting a cleaner energy future.
Installation Flexibility
Heat pumps work with ducted systems, ductless mini-splits, and hybrid configurations—making them suitable for a wide range of homes.
Rebates, Tax Credits & Financing Made Simple
One of the biggest advantages of upgrading to a heat pump is the availability of rebates.
