A furnace is the best option for these areas, as heat pumps become inefficient when outdoor temperatures get too low. Since temperatures can drop into the 20s or lower, a gas or propane furnace ensures reliable heating regardless of the weather. Alternative Option: A dual-fuel system with a heat pump and a backup furnace can offer year-round efficiency. The heat pump is used for mild weather, and the furnace is used for extreme cold. Comparing Costs: Heat Pump vs. Furnace Long-Term Savings If you live near the coast or in inland areas with mild winters, a heat pump can save you money on heating and cooling costs. If you live in the mountains, investing in a high-efficiency gas furnace can be the better long-term choice, as heat pumps will struggle in extremely low temperatures. Final Verdict: Which One Should You Choose? ✔️ Choose a Heat Pump If: You live near the coast or in a desert area where winters are mild. You want lower energy bills and a more eco-friendly heating system. You like the idea of one system that handles both heating and cooling. ✔️ Choose a Furnace If: You live in the mountains or anywhere with cold winters where temperatures frequently drop below freezing. You want powerful, consistent heating regardless of outside temperatures. Your home already has natural gas hookups, making installation more affordable. Considering a Hybrid Solution? If you’re on the fence, a dual-fuel system combines the benefits of a heat pump and a furnace. This setup allows the heat pump to handle most of the heating (and all of the cooling), while the furnace kicks in only when necessary. This is a great energy-efficient solution for homes in variable climates like San Diego’s inland and mountain regions. Conclusion When deciding between a heat pump and a furnace, your climate plays the biggest role in determining which system will provide the best comfort and efficiency. For coastal and desert areas, a heat pump is the clear winner. For mountain areas, a gas furnace is the more reliable option.
