What is the difference between a stage one and stage two furnace?

The difference between one-stage and two-stage furnaces is in how the two operate. On stage furnaces operate at 100% power when running, whereas two-stage furnaces constantly operate at 60-70% power, only increasing to 100% operating power when signaled by an extreme shift in indoor temperature.

Is it worth getting a 2 stage furnace?

The two-stage furnace is more efficient than the one-stage because it doesn't release as much fuel into the heat exchanger when the home is only somewhat cold. If it's 5 to 10 degrees outside, a two-stage furnace will run in the partially-open position and only use 70% of the energy it normally would.

Can I use a 2 stage thermostat with a single stage furnace?

Yes, I meant to say any two stage furnace... Using a 2 stage thermostat will not harm the furnace. And because the control board is compatible with a single stage thermostat, the furnace will still operate both stages. The control board would, as you say, start the second stage after about 10 minutes.

What is the Difference Between Single-Stage, Two-Stage, and Modulating Furnaces?



Does a 2-stage furnace use more electricity?

For two-stage designs, the DOE test procedure consistently shows a reduction in energy consumption by about 3% compared to single-stage furnaces at the same AFUE level. In contrast, the 2006 AHRAE test procedure shows almost no difference in the total energy consumption at the same efficiency level.

Does a 2 stage furnace use less gas?

Two-stage furnaces cost more to purchase and install than traditional models. But factoring in their 20-25 percent fuel efficiency advantage, and assuming a normal lifespan of about 20 years, the extra cost will be more than erased by the cumulative energy savings.

Is a two stage furnace quieter?

Two stage furnaces

The second stage is the full capacity of your system. 1/3 compressor capacity is the 1st stage. 1st stage is more efficient than 2nd stage, but systems are designed to use both stages, so no worries there. It's fine for your system to have long run times when it's cold outside.
