Should I Install a Gas Furnace, Heat Pump, or Boiler?

Need Help Choosing the Best Heating System for Your Rockford Home?

Deciding between a gas furnace, heat pump, boiler, or hybrid system depends on your home’s layout, existing infrastructure, and long-term efficiency goals. Because every Rockford home is different, the experts at Gilley’s Heating & Air Conditioning take the time to evaluate your space, your budget, and your comfort needs to recommend the system that makes the most sense for Northern Illinois winters.

The best heating system for your Rockford home depends on existing infrastructure, fuel availability, budget, and comfort priorities. Here's how to decide between the three main options for Northern Illinois winters.

Choose a Gas Furnace if:

• You have existing ductwork and natural gas service
• You want the lowest operating costs (gas cheaper than electricity in Rockford)
• You need reliable powerful heat for extended -10°F cold periods
• You plan to add central AC later (works with same ductwork)
  

Choose a Heat Pump if:

• You want one system for both heating and cooling
• You're energy-conscious and prioritize efficiency over fuel cost
• Your home lacks natural gas service
• You qualify for substantial heat pump rebates (up to $2,000 federal if available)
  

Choose a Boiler if:

• You have existing radiators or radiant heating
• You suffer from allergies (no air circulation reduces dust)
• Ductwork installation is impractical in your older home
• You want quiet, even heat without temperature swings
  

Choose a Hybrid System if:

• You want maximum efficiency and reliability
• You have both gas service and adequate electrical capacity
• Long-term operating cost savings are priority



About 70% of Rockford homeowners choose high-efficiency gas furnaces for the best balance of upfront cost, operating efficiency, and reliable performance in Northern Illinois winters. Heat pumps work well but typically need backup heat below 0°F.
