What efficiency furnace should I buy?

A standard efficiency furnace provides 80% annual fuel utilization efficiency (AFUE). In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust. These days, 95% AFUE is a common rating among new gas-powered furnaces. So a 95% furnace is more efficient than an 80% furnace.

Does a 2 stage furnace really save money?

Your two stage furnace saves on energy costs because it doesn't burn as much fuel. Your two-stage furnace saves gas because it doesn't dump as much fuel into the heat exchanger when it's only moderately cold outside.

Should I buy a high efficiency furnace?

High-efficiency furnaces do a better job of transferring the heat they generate into your house instead of up their chimneys. This results in you using less energy to run them, potentially lowering your heating bill. In exchange for their ability to save you money, they're more mechanically complex and more expensive.

Are new electric furnaces more efficient?


An electric furnace is the more efficient of the two. It may have an annual fuel-utilization-efficiency (AFUE) rating as high as 100 percent. The higher cost of a more efficient gas system will most often be offset by lower fuel costs in regions with harsh winters.

And New Furnaces Are Indeed Much More Efficient

Which is better Trane or Lennox?

For mid-level and basic air conditioners, then Carrier and Trane have better warranties than Lennox.

Can you install a furnace yourself?

Gas Supply:

Is a higher BTU furnace better?

A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.
