How Long Should an HVAC System Last?

Most HVAC systems have a lifespan of 15–20 years with proper maintenance. However, several factors can shorten or extend this timeline.

7 Signs It's Time to Replace

1. Your System Is Over 15 Years Old

If your furnace or air conditioner is approaching or past the 15-year mark, it's time to start planning for replacement.

2. Rising Energy Bills

If your heating and cooling costs have steadily increased despite consistent usage, your system is losing efficiency. A new high-efficiency system can reduce energy costs by 30–50%.

3. Frequent Repairs

The 50% Rule: If a repair costs more than 50% of the value of a new system, replace it.

4. Uneven Temperatures

Hot and cold spots throughout your home indicate your system can no longer distribute air effectively.

5. Excessive Noise

Banging, rattling, squealing, or grinding sounds indicate mechanical failure.

6. Poor Air Quality

If you notice more dust, humidity problems, or musty odors, your HVAC system may no longer be filtering effectively.

7. R-22 Refrigerant

If your AC uses R-22 (Freon), it's time to upgrade. R-22 has been phased out, making repairs extremely expensive.
