Gas vs Electric Furnace: Which Is Better
Choosing between options requires understanding how each performs in real-world conditions. Here's a practical comparison to help you decide.
#
Key Differences to Consider
Operating Costs:
Gas typically costs less per unit of heat produced in most areas, though this varies by local utility rates. Electric systems have lower upfront costs but may cost more to operate depending on your electricity rates. Calculate based on your specific utility costs for an accurate comparison.
Performance Characteristics:
Gas systems produce hotter air and heat spaces quickly. Electric systems provide more consistent, gradual heating. In extremely cold weather, gas systems maintain effectiveness while some electric systems (particularly heat pumps) may struggle.
Installation Requirements:
Gas requires a gas line connection and venting for combustion byproducts. Electric needs only electrical connections but may require panel upgrades for high-capacity units. Your home's existing infrastructure affects which option is simpler to install.
Lifespan and Maintenance:
Gas systems typically last 15-20 years with proper maintenance. Electric systems often last longer since they have fewer mechanical components. However, repair costs for gas systems are often lower due to simpler mechanical designs.

Making Your Decision
Consider having a qualified technician assess your specific situation. They can evaluate your home's characteristics and recommend options based on your needs rather than generic advice.
Get multiple opinions if you're making a significant investment. Different technicians may suggest different solutions, and understanding the reasoning behind each recommendation helps you make an informed choice.
