Gas vs. Electric Furnaces: Which Is Right for You?

Choosing between a gas or electric furnace depends on your home’s infrastructure, utility availability, and heating needs. Gas furnaces are known for their powerful heating capabilities and lower operating costs over time, especially in regions with cold winters and access to affordable natural gas. These units heat quickly and are ideal for larger homes.

Electric furnaces, on the other hand, tend to have lower upfront costs and are often easier to install, especially in homes without gas lines. They also offer quiet operation and a slightly longer lifespan due to fewer moving parts. At Purl's Sheet Metal & Air Conditioning, our experienced technicians can assess your home and help you make the right choice based on energy efficiency, performance, and your budget.

Signs It’s Time for a Furnace Replacement

A well-maintained furnace can last 15 to 20 years, but when issues start to pile up, it may be time to consider a replacement. Common signs include:

  • Frequent or costly repairs
  • Rising utility bills without a change in usage
  • Uneven heating throughout your home
  • Strange noises like banging, popping, or squealing
  • A yellow or flickering pilot light (gas furnaces)
  • Short-cycling or constant running
  • System is 15+ years old

If you notice one or more of these signs, Purl's Sheet Metal & Air Conditioning can help determine whether a repair or a new system is the better investment for your comfort and wallet.

How to Maintain Your Furnace for Optimal Performance

Regular furnace maintenance is essential to prolonging the life of your system and keeping it operating safely and efficiently. During a maintenance visit, our certified technicians inspect all components, clean burners and filters, check electrical connections, and verify airflow and combustion levels.
