Finding the right gas furnace can feel overwhelming with so many options and technical terms, but we’re here to simplify the process. At Affordable Comfort, we’re committed to helping you make an informed decision, whether your focus is energy efficiency, comfort, or budget.
How a Gas Furnace Works
Modern gas furnaces use natural gas or propane to warm your home efficiently. Here's how:
Ignition: Burners ignite to heat the furnace’s heat exchanger.
Heat Transfer: The heat exchanger safely warms air.
Air Circulation: A blower motor moves the warm air through your ductwork.
Thermostat Control: Regulates your home’s temperature for consistent comfort.
Today’s furnaces are quieter and more efficient, ensuring dependable warmth without spiking energy bills.
Furnace Stages: Single-Stage, Two-Stage, and Modulating
The term “staging” describes how a furnace delivers heat:
Single-Stage: Fully on or off—cost-effective but less efficient.
Two-Stage: Adjusts between low and high settings for better energy efficiency and comfort.
Modulating: Offers precise temperature control by adjusting in small increments.
Choosing the right stage depends on your budget, home size, and comfort preferences.
Furnace Motors: PSC, ECM, and Variable-Speed ECM
The motor type impacts energy use, noise, and airflow consistency:
PSC Motors: Basic and affordable but less efficient.
ECM Motors: Smarter technology for quieter, more efficient operation.
Variable-Speed ECM Motors: Best for energy savings, even temperatures, and quiet performance.
Why Proper Sizing Matters
A furnace that’s too large or too small for your home can cause uneven heating, higher energy bills, and increased wear and tear. Proper sizing ensures optimal performance, lower costs, and reliable comfort.
