10 Questions to Ask Before Furnace Replacement in Nashua


As the chilly weather approaches, nothing is more crucial than maintaining comfort and peace of mind in your home. The right home heating system can make all the difference. According to the U.S. Department of Energy, heating and cooling can account for over half of the average homeowner’s utility expenses. An outdated or inefficient furnace can significantly increase your energy bills. Similarly, a new furnace that’s improperly sized for your home can still lead to higher costs. Here’s what to think about before replacing the furnace in your Nashua home.

Choosing a furnace wisely offers many benefits. A properly selected furnace will meet your family’s comfort needs, lower utility bills, improve indoor air quality, and extend your furnace’s life, ensuring you enjoy a warm, stress-free fall and winter for years to come.

Several features of a furnace, such as type, size, and efficiency, impact its cost and longevity. Choosing the wrong furnace can lead to issues that cause stress rather than comfort during the winter months:

  • Poor system efficiency – Each home has unique heating needs. An incorrectly sized or unsuitable furnace, even if energy-efficient, can be inefficient.
  • Increased repair and maintenance costs – The wrong furnace can strain the system, leading to frequent maintenance and repairs.
  • Shortened furnace lifespan – A furnace struggling to meet heating demands will cycle more often, increasing wear and reducing its lifespan.
  • Inconsistent heating during fall and winter – The right furnace should provide consistent heating during cooler months and handle constant use in winter.
  • Increased safety risks – An incompatible furnace can raise the risk of fires and carbon monoxide exposure.

Key Questions to Ask About Your New Furnace

When selecting a new furnace, ask these crucial questions to avoid heating issues and ensure optimal comfort:

  • How have your family’s heating needs changed? Consider new family members, such as babies or elderly parents, who may have different comfort needs.
  • What are your other heating needs? Modern furnaces can be programmed to heat specific areas and operate on schedules.
  • What energy-efficient models are available? Higher-rated AFUE models can significantly reduce utility bills.
  • What furnace brands are available? Compare popular brands like Trane, Lennox, Goodman, Rheem, York, and Carrier.
  • Are there any special deals or rebates? Look for deals from contractors, manufacturers, and incentives from government and utility companies.
  • How much space does your home have? Consider your home’s square footage to choose a furnace that can effectively heat your space.
  • What areas need the most heat? Some systems can focus heating on specific rooms.
  • How is your indoor air quality? Address issues like mold, mildew, pollen, and dust to improve air quality.
  • What fuel type should you choose? Options include gas, electric, and solar, depending on your location.
  • What is the age of your current furnace? If your furnace is over 10 years old, consider a more energy-efficient replacement to reduce costs and improve performance.

Regardless of the furnace type you choose, always opt for the highest energy efficiency model within your budget. The Annual Fuel Utilization Efficiency (AFUE) rating indicates furnace efficiency. Energy Star certification requires gas furnaces in northern states to have a 95% AFUE or higher, 90% or higher in southern states, and 85% or higher for oil furnaces nationwide. Selecting a high-efficiency furnace maximizes your seasonal savings on heating costs.
