Repair versus replacement: how to decide in La Porte, TX

Choosing between repair and replacement is the most common bottom-of-funnel decision. Consider these factors:

• Age of the system: Most air conditioners and heat pumps older than 10 to 15 years are nearing the end of useful life; frequent major repairs favor replacement.
• Frequency and cost of repairs: If repairs total a substantial portion of replacement cost over a short period, replacement is more economical.
• Efficiency and comfort: Older systems with low SEER ratings may cost much more to run in La Porte’s hot summers. Replacing with a higher-efficiency unit can reduce bills and improve comfort.
• Refrigerant phase-outs: Systems that require phased-out refrigerants may be more costly to recharge and repair.
• Ductwork and home changes: If duct leakage or an increase in home square footage is driving poor performance, replacement combined with ductwork improvements can be the best long-term solution.
• Resilience needs: For homes prone to storms or salt-air exposure, newer equipment with coastal-rated features and surge protection may avoid recurrent failures.

When replacement is the best choice, a proper load calculation and duct evaluation ensure the new system delivers the expected comfort and efficiency.
