A 2-stage furnace is a heating system that operates at two different levels of heat output, unlike a traditional single-stage furnace that only runs at full capacity. This allows for better efficiency, improved comfort, and more consistent indoor temperatures throughout your home.
How Does a 2-Stage Furnace Work?
- Low Stage: Most of the time, the furnace runs at a lower heating capacity (around 60-70% of full power). This helps maintain a steady, comfortable temperature without excessive energy use.
- High Stage: When temperatures drop significantly and more heat is needed, the furnace automatically switches to full capacity to keep your home warm.
