Difference between Two-Stage Furnace and One Stage Furnace

Two-stage furnaces and one-stage furnaces are two of the most common types of furnaces available on the market. Both have their own unique benefits that make them perfect for different homes. So, which one is the best for your home? Let’s take a closer look at the difference between a two-stage furnace and a one-stage furnace.

What is a Two-Stage Furnace?

A two-stage furnace is a forced-air heating system that has two levels of heating output: low and high. Most furnaces are single-stage, meaning they only have one level of heating output. Two-stage furnaces provide better temperature control because they operate at lower temperatures most of the time and only kick into high gear when more heat is needed.

This not only keeps your home more comfortable but also reduces wear and tear on the furnace, which can prolong its lifespan. In addition, two-stage furnaces tend to be more energy-efficient than their single-stage counterparts, so you can save money on your energy bills. If you’re in the market for a new furnace, a two-stage model is definitely worth considering.

What is a One-Stage Furnace?

One-Stage Furnace is a high-efficiency, permanently lubricated gas furnace. One-Stage Furnace is recognized as one of the most efficient and eco-friendly ways to heat your home. One-Stage Furnace has a number of features that make it an attractive choice for homeowners. One-Stage Furnace is quieter than other types of furnaces, and it doesn’t produce any emissions.

One-Stage Furnace is also more energy-efficient than other furnaces, and it will save you money on your energy bills. One-Stage Furnace is a great choice for homeowners who are looking for a safe, efficient, and eco-friendly way to heat their homes. Contact your local heating and cooling contractor to learn more about One-Stage Furnace and how it can benefit your home.

Difference between Two-Stage Furnace and One-Stage Furnace

There are two main types of furnaces: one-stage and two-stage. As the name suggests, a one-stage furnace has only one setting for heat output. This means that the furnace is either on or off, and it runs at full capacity when it’s on. Two-stage furnaces, on the other hand, have two settings for heat output: low and high.

This gives you more control over the temperature in your home, as you can set the furnace to run at a lower setting for most of the time and only switch to high when you need a boost of heat. Two-stage furnaces are more energy-efficient than one-stage furnaces, as they don’t have to work as hard to maintain a comfortable temperature. However, they are more expensive to purchase and install.


The two-stage furnace is a more efficient option for your home because it warms up the air slowly and circulates it throughout your house. This prevents cold spots and drafts, saving you money on your energy bill. If you’re looking to upgrade your home heating system, we recommend the two-stage furnace.
