How Often Should You Replace Your HVAC System?

Why This Matters

Your HVAC is one of the most expensive home components. Knowing when to replace saves thousands.

Key Signs to Watch For

• Age over 15 years: Systems nearing end of life lose efficiency.
• Rising energy bills: Aging systems work harder for same temperature.
• Frequent repairs: More than twice a year means replace.
• Inconsistent temperatures: Some rooms too hot, others too cold.

What You Should Do

1. Track repair costs — If repairs exceed 50% of new system cost, replace.

2. Check refrigerant — R-22 (Freon) is phased out and expensive.

3. Look at SEER ratings — Modern systems are 20-30% more efficient.
