Which HVAC Brands Last the Longest?
Carrier Gas Furnace Cost: $3,800–$10,000+
Higher-efficiency furnaces cost more upfront but can significantly reduce heating expenses over time. Expect gas furnaces to range from $3,800 to over $10,000 depending on the model, efficiency, and smart technology capabilities.
Yes, Lennox is generally more expensive than Carrier. Both are premium HVAC brands, but Lennox typically costs about $1,000 to $3,000 more upfront for comparable efficiency levels and model tiers.
With Carrier you pay extra for brand, premium tier, features. If your home doesn't need ultra‑premium performance, those extra dollars don't always return a real difference. In many mid‑range homes, the comfort difference (if installation is done properly) will be similar.
The $5,000 rule is a guideline to help homeowners decide whether to repair or replace their HVAC system. You multiply the age of your unit by the cost of the needed repair. If that number exceeds $5,000, replacing your HVAC system is often more cost-effective.
Average Cost to Replace a Furnace
However, the cost of furnaces can range widely depending on their size, type, and efficiency, and homeowners can generally expect a new furnace to cost anywhere between $3,800 and $10,000. If efficiency is important to you, high-efficiency models can reach up to $12,000.
And when you purchase a new furnace — should you make the wrong choice — the noise will still be there. So make sure your purchasing decision of the best furnace for your family includes carefully consideration of the sound levels it will generate.

Carrier furnaces are manufactured by Carrier Global Corporation, a major HVAC company headquartered in Palm Beach Gardens, Florida. They build these units in several U.S. facilities, including their primary residential headquarters in Indianapolis, Indiana.
The heat exchanger is often considered the most costly part of a furnace to repair or replace. It is a critical component that transfers heat from the combustion process to the air that circulates throughout your home. Over time, heat exchangers can crack due to the constant heating and cooling cycles they undergo.
Yes, you should highly consider replacing a 30-year-old furnace. Most furnaces have a lifespan of 15 to 20 years. At 30 years old, your system has likely outlived its expected life. It is operating at a much lower efficiency than modern units and presents a significantly increased risk of catastrophic breakdown or dangerous carbon monoxide leaks.
Carrier is our pick for the best furnace brand because it delivers strong efficiency, offers a 10-year limited parts warranty, and meets Energy Star performance standards. Choosing the right furnace plays a key role in your home's comfort, energy efficiency, and long-term costs—especially in colder climates.
Your ideal furnace depends on your home size, climate, and budget. If you're prioritizing ultra-high efficiency, Lennox is our top choice. Carrier and Trane offer strong reliability, while Goodman and Rheem are ideal for those prioritizing cost savings. Bryant delivers premium features without the premium price tag.

Purchasing in these shoulder seasons ensures faster installation times and better negotiating power compared to winter peak season.
Carrier delivers on that promise with better engineering, superior efficiency, and proven reliability. Yes, you'll pay a bit more than the cheapest option out there, but you're investing in comfort, savings, and peace of mind for years to come.

ENERGY STAR certified oil furnaces that use certain fuels are eligible. The equipment must be rated by the manufacturer for use with fuel blends at least 20 percent of the volume of which consists of biodiesel, renewable diesel, or second-generation biofuel.
Yes, R-32 is generally considered better than R-410A due to its higher energy efficiency, lower global warming impact, and use of a single compound. However, because it is mildly flammable (A2L classification), it requires dedicated HVAC systems rather than a direct replacement.
