Our Guide To Choosing The Best Gas Furnace For Your Home

Best Gas Furnace

If you are in the market to buy a new gas furnace, then you’ve found the first article you’ll need to help you pick the right one. We’re here to help you narrow down all the choices in our quick guide to choosing the best gas furnace for your home.

Look For Efficiency

When you are deciding what type of furnace will replace your old one, the first thing you’ll notice is that efficiency has come a long way. Some of the best furnaces made 10-20 years ago have similar efficiency to the most basic furnace models made today. So, if you are buying new, you will almost always see an improvement when it comes to efficiency – and, in turn, an improvement on your energy bill.

In addition, Energy STAR rated furnaces “will be up to 16 percent more energy efficient than baseline models, and can save an average of $94 in energy costs per year,” according to

Keith Hill, the technical support manager at Minnesota Air, says that general fuel efficiency is the first thing you decide.

“Are you in the market for an 80 percent efficient furnace or a 90+ efficiency?  If you have a metal chimney on your existing furnace – it’s an 80 percent (or less) efficient furnace. It can be replaced with a 90+ percent (furnace), but there may be additional costs due to the venting. All 90 percent efficient furnaces vent with PVC (plastic) venting.”

Pick A Brand You Trust

Knowing that the manufacturer of your new furnace has a quality reputation is also important. You don’t want to buy an off-brand because it’s cheaper upfront, and then come to find out later that the parts are expensive to repair or hard to come by, and that the company may be out of business in a few years. By choosing a well-known, established brand – like Carrier – you’ll know that you won’t have trouble getting your furnace serviced in the future and that your new furnace has a great warranty.

Good, Better, Best: What Option Is In Your Budget?

You’ll find that all gas furnace manufacturers have models made to fit all budgets. Keith says that there are good, better, and best options – including the warranty.

“Generally speaking, I always recommend that you pick the best furnace you can afford,” he says. “These extra features aren’t just fluff, they truly do provide better comfort and reduce your fuel bills.”

Keith says that he personally recommends furnaces in the better/ best groupings. For example, his ‘better’ pick is a furnace with 95+ percent annual fuel utilization efficiency (AFUE), and a two-stage heating system with a basic ECM (electronic motor). He says it is a very good comfort system and provides excellent energy savings.  

His ‘best’ pick would be the Carrier Infinity furnace that has modulating heat.

“It operates at 97% and has a fully featured ECM motor for the very best in comfort and fuel savings,” he says. “Both of these choices have a best-in-class warranty.”
