Best Gas Furnace 2021
Unlocking Energy Savings: A Deep Dive into the Best Gas Furnaces of 2021
As we navigate increasingly eco-conscious times, homeowners and businesses alike are seeking ways to reduce their carbon footprint and, crucially, lower those ever-rising energy bills. Upgrading to a high-efficiency gas furnace represents a significant step in achieving both goals. This article provides an in-depth look at some of the best gas furnace options available in 2021, focusing on energy efficiency, cost savings, and the integration of smart home technology.
Understanding Gas Furnace Efficiency: AFUE and Beyond
The most important metric to consider when evaluating a gas furnace is its Annual Fuel Utilization Efficiency (AFUE) rating. AFUE indicates how efficiently a furnace converts fuel into usable heat. A higher AFUE percentage translates to less wasted energy and lower heating bills. Energy Star certified furnaces must have an AFUE of 95% or greater. Furnaces with ratings above 90% are considered high-efficiency, while older models often hover around 80% or even lower.
Consider this: switching from an 80% AFUE furnace to a 95% AFUE furnace could potentially save you 15% or more on your annual heating costs. This can translate to hundreds of dollars saved each year, depending on your location, fuel costs, and usage patterns.
Beyond AFUE, look at features like variable-speed blowers, modulating gas valves, and sealed combustion chambers. These technologies further enhance efficiency and provide more consistent heating.

The ROI of a High-Efficiency Gas Furnace
While the upfront cost of a high-efficiency gas furnace can be higher than that of a standard model, the long-term savings can be substantial. Here's a breakdown of the potential ROI:
- Reduced Energy Bills: As mentioned earlier, a high-efficiency furnace can save you 15% or more on your annual heating costs.
- Increased Home Value: A new, energy-efficient furnace can increase the value of your home, making it more attractive to potential buyers.
- Government and Utility Rebates: Many government agencies and utility companies offer rebates for installing Energy Star certified appliances, including gas furnaces. Be sure to check for available incentives in your area.
- Reduced Maintenance Costs: Newer furnaces tend to be more reliable and require less maintenance than older models.
To calculate your potential ROI, consider your current heating costs, the AFUE of your existing furnace, and the AFUE of the new furnace you are considering. Factor in any available rebates and the expected lifespan of the new furnace. A qualified HVAC contractor can help you estimate the potential savings and payback period for your specific situation.
Smart Home Integration: Taking Control of Your Heating
Integrating your new gas furnace with a smart thermostat and other smart home devices can further enhance energy efficiency and comfort. Smart thermostats allow you to control your heating system remotely, set custom schedules, and receive alerts if there are any issues. Many smart thermostats also learn your heating preferences and adjust the temperature automatically to optimize energy savings.
Features to look for in a smart thermostat include:
- Remote Control: Control your thermostat from anywhere using your smartphone or tablet.
- Custom Scheduling: Set different temperature schedules for weekdays, weekends, and holidays.
- Geofencing: Automatically adjust the temperature when you leave or approach your home.
- Learning Capabilities: The thermostat learns your heating preferences and adjusts the temperature accordingly.
- Energy Reporting: Track your energy usage and identify areas where you can save money.
Popular smart thermostat options include the Nest Learning Thermostat, the Ecobee SmartThermostat with voice control, and the thermostats offered by furnace manufacturers themselves (like Carrier's iComfort and Trane's ComfortLink II). Ensure that the thermostat you choose is compatible with your new gas furnace.
Choosing the Right HVAC Contractor
Selecting a qualified and experienced HVAC contractor is crucial for ensuring a successful furnace installation. Look for a contractor who is licensed, insured, and has a proven track record of installing high-efficiency gas furnaces. Get multiple quotes and ask for references. A good contractor will be able to assess your home's heating needs, recommend the right furnace for your budget and energy goals, and install it properly.
Important Questions to Ask Your HVAC Contractor:
- Are you licensed and insured?
- How many years of experience do you have?
- Do you have experience installing high-efficiency gas furnaces?
- Can you provide references from previous customers?
- What is the warranty on the furnace and the installation?
- Do you offer maintenance plans?
