Knowing When to Replace Your Furnace

Buying a new furnace in 2025 means understanding when it's time to replace your current one. Here are some signs to look out for:

  • Age: Furnaces last about 15-20 years. If yours is in this age bracket or beyond, replacing the furnace and air conditioner might be due.
  • Frequent repairs: A furnace that needs constant repairs could be a liability rather than an asset.
  • High energy bills: As furnaces age, they become less efficient, leading to increased energy costs. A significant rise in your heating bills could mean your furnace is past its prime.
  • Inconsistent heating: If some areas of your home are colder than others, or if the temperature fluctuates, this could be a sign of a failing furnace.
  • Strange noises: Unusual noises like banging, squealing, or rattling often indicate mechanical problems that might necessitate replacing the furnace and air conditioner.

When you replace an old furnace, you gain several advantages:

  • Improved energy efficiency: Newer models are designed to be more energy-efficient, reducing both your energy bills and your carbon footprint.
  • Enhanced comfort: A new furnace provides consistent heating, creating a comfortable environment in every room.
  • Reliability: With a new furnace, you can avoid frequent breakdowns and expensive repairs.
  • Advanced features: Modern furnaces offer advanced features like programmable thermostats and zoning capabilities, giving you more control and customization.

So, if you're considering buying a furnace in 2025, evaluate these factors to determine the right time for a replacement. The experts at Sears Home Services are ready to assist you in choosing the best furnace for your needs.

The 5 Questions to Ask Before Buying a New Furnace in 2025

When purchasing a furnace, it's important to ask the following questions:

  1. What is the right furnace size for my home? An HVAC professional can assess your home and recommend the ideal furnace size.
  2. What warranty options are available? Understand the warranty terms, including its duration, coverage, and any maintenance obligations.
  3. Are maintenance plans available? Regular maintenance keeps your furnace running smoothly and extends its lifespan. Ask about the HVAC company's maintenance plans.
  4. How energy-efficient is the furnace? The furnace's AFUE (Annual Fuel Utilization Efficiency) rating tells you how efficiently it converts fuel into heat. A high AFUE rating indicates more energy savings.
  5. Are there financing options? Buying a new furnace can be a major investment. Ask about financing options to make the purchase more manageable.
