Should I Repair or Replace My Furnace?

Choose furnace repair when your system is under 10 years old, repair costs are less than 30% of replacement cost, and performance is otherwise reliable. Choose replacement when your furnace is 15+ years old, experiences frequent breakdowns, or has safety issues. The right decision depends on system age, repair frequency, cost, and safety.

How Do I Know If My Furnace Is Worth Repairing?

Age and Condition Factors

• Under 10 years old: Still within primary lifespan.
• Single component failure: Problems like ignitors, thermostats, or filters.
• Consistent performance: Reliable heating history.
• No safety issues: Proper combustion and ventilation.

Financial Factors

• Repair cost under 30% of replacement: For example, if a new furnace is $10,000, repairs under $3,000 are reasonable.
• Few past repairs: First or second major issue only.
• Stable energy bills: No noticeable efficiency loss.

McKinney-Specific Considerations

• Newer neighborhoods (Trinity Falls, Inspiration): Systems often still under warranty — repair preferred.
• Mixed-age areas (Craig Ranch, Westridge): Evaluate based on system age.
• Older neighborhoods (Historic Downtown): Systems may be candidates for replacement.

When Should I Replace My Furnace?

Age Indicators

• 15–20 years old: Near end of useful life.
• 20+ years old: Immediate replacement recommended.
• Original equipment: Lacks modern safety and efficiency features.

Cost-Benefit Indicators

• Repairs exceed 50% of replacement cost: Example: $5,000 repair on $10,000 system.
• Multiple major repairs in 2 years: Suggests systemic failure.
• Rising energy bills: Efficiency decline due to wear.

Safety Indicators

• Cracked heat exchanger: Cannot be safely repaired.
• Carbon monoxide detection: Replace immediately.
• Frequent safety shutdowns: Indicates critical failure.
• Yellow or irregular pilot light: Unsafe combustion.

Watch for Red Flags

• Pressure to replace immediately
• Exaggerated safety warnings without proof
• Refusal to offer repairs
