Buying Guide

AFUE Efficiency

AFUE tells you how efficiently the furnace converts fuel into heat. Higher numbers like 92% or 96% generally mean better efficiency than 80% models, which can matter over time if you heat your home often.

BTU Output

BTU output shows heating capacity. Smaller homes may do fine with 60,000 or 80,000 BTUs, while larger homes may need 100,000 BTUs or more. Choosing the right output helps avoid undersizing or oversizing.

Stage Type

Single-stage furnaces are simpler, while two-stage models offer a more layered approach to heating. If you want a more advanced setup, two-stage units are often worth a look.

Cabinet Width

Cabinet width matters when you are checking fit. Many of the models here are 17.5 inches or 21 inches wide, but one larger option is 24.5 inches. Always confirm available space before buying.

Installation Style

These furnaces are listed as upflow/horizontal, so make sure that matches your installation needs. Installation compatibility is just as important as price or efficiency.

Price and Rating

Split your decision between budget and customer rating. A lower price can be attractive, but higher-rated models often provide more confidence when you are narrowing the list.

The Goodman 96% AFUE Two Stage 100k BTU model is the strongest all-around choice in this list because it combines high efficiency, two-stage operation, and a strong 4.7 rating.

Which furnace is the best value?

Are 96% AFUE models better than 80% AFUE models?

96% AFUE models are more efficient, which means less fuel is wasted during heating. However, 80% models often cost less upfront, so the better choice depends on budget and efficiency goals.

How do I know what BTU size I need?

BTU needs depend on home size, insulation, and climate. Smaller homes may be fine with 60,000 BTUs, while larger homes may need 80,000 or 100,000 BTUs or more.

What does single-stage mean?

Single-stage means the furnace runs at one fixed output level. It is generally simpler than a two-stage model, which can offer more gradual heating performance.

Should I choose a furnace based on rating alone?

No. Rating can be helpful, but it should be weighed alongside efficiency, size, heating capacity, and your home’s installation requirements.
