Is It Time for a New Furnace? Key Warning Signs
Many homeowners wonder if a repair is enough or if it’s time for a full replacement. An aging, inefficient unit can quickly become a costly cycle. If you experience the following issues, it may be time to replace your furnace:

Common Warning Signs
- Your Furnace is Over 15 Years Old: Most furnaces last 15–20 years. Beyond this, efficiency drops significantly.
- Frequent Repairs: If repairs are needed more than once a year, the costs often outweigh replacement.
- Rising Energy Bills: Older systems consume more energy to produce the same heat.
- Uneven Heating: Cold spots and uneven airflow indicate declining performance.
- Unusual Noises: Loud banging, rattling, or popping suggest serious mechanical problems.
- Safety Concerns: A cracked heat exchanger or carbon monoxide risks are critical warnings.

Understanding the Cost of a New Furnace
Replacing your furnace is a significant investment that boosts both comfort and home value. The total cost depends on several factors:
- Furnace Type and Efficiency: High-efficiency models cost more upfront but lower energy bills long-term.
- System Size: Correct BTU output prevents inefficiency and unnecessary wear.
- Installation Complexity: Modifications to ductwork, gas lines, or ventilation can affect cost.
