Part 5: Knowing When to Replace Your Gas Furnace

Replacing your gas furnace at the right time is crucial for optimal performance, energy efficiency, and cost-effectiveness. Here are some factors to consider when determining if furnace replacement is the best choice for your situation:


The 5,000 Rule:

The “5,000 Rule” is a popular guideline to help determine whether it’s time to replace your furnace. Simply multiply the age of your furnace by its annual repair cost.

If the product exceeds $5,000, it may be more cost-effective to replace the furnace rather than continuing to repair it. 2.

Furnace Age:

Furnaces typically last between 15 to 20 years. If your furnace is approaching or exceeding this lifespan and experiencing frequent breakdowns or performance issues, replacing it may be the more practical choice in terms of long-term reliability and energy efficiency.
