Should I choose a heat pump or gas furnace for my home?

A modern heat pump is usually the better choice unless you regularly see -20°F. Heat pumps are 3–4x more efficient than gas, lowering bills in most climates, and they also cool your home. Gas still works better in extreme cold and heats faster, but it has downsides like combustion byproducts and price volatility. Your decision depends on climate and local energy prices—check utility rates and rebates.
