When to Replace Your AC System

Knowing when to replace rather than repair can save you money in the long run. Look for these signs.

System Is 10–15+ Years Old

Most AC systems last 12–15 years in Florida's climate. Older systems are less efficient and more prone to costly breakdowns.

Repairs Cost More Than 50% of Replacement

If a single repair exceeds half the cost of a new unit, replacement is usually the smarter financial decision.

Rising Energy Bills

Older, inefficient systems can consume significantly more electricity. A new high-efficiency system can reduce energy costs by 20–40%.

Uses R-22 Refrigerant

R-22 (Freon) has been phased out and is now extremely expensive. If your system uses R-22, replacement is highly recommended.

Uneven Cooling Throughout Home

An aging system that can no longer maintain consistent temperatures is losing capacity and needs to be replaced.

Frequent Breakdowns

If you've needed multiple repairs in the past 12 months, you're likely spending more maintaining an old system than a new one would cost.
