With routine service, a gas furnace lasts 15 to 30 years. Annual inspections, filter changes, and prompt repairs help the unit deliver steady heat throughout its life span. When repair bills climb or performance drops—especially in harsh climates—it may be smarter to put your money toward a replacement rather than another short-term fix.
Natural gas is often the cheapest way to heat a home, offering lower monthly bills than propane or electric systems. Propane can beat electricity in some regions, but its advantage depends on local fuel prices and climate. Check your utility rates, then talk with a local HVAC pro to see which option delivers the best long-term value where you live.
For most households, a high-efficiency furnace is worth the higher upfront cost. The unit uses less fuel, which lowers monthly bills and shrinks your carbon footprint. You’ll also notice quieter operation and steadier room temperatures. Over time, those savings and comfort perks pay back the initial premium, and can even bump up resale appeal.
Furnaces heat air and move it through ducts, while boilers heat water or create steam that flows to radiators. Installation costs overlap, but the systems feel different: forced-air heat is quicker, and radiant heat is often more even and quiet. Comparing comfort preferences, existing infrastructure, and fuel costs will help you decide which setup fits your home.
Yes—pairing a new furnace with a professional energy audit is a smart move. The audit pinpoints air leaks, insulation gaps, and duct issues that let heat slip out and money drain away. Fixing those trouble spots while you’re upgrading the furnace helps the new system run at peak efficiency and can trim your utility bills even further.
