If your system is showing these signs, repairs may no longer be cost-effective — a new system could save you money long-term.
AC systems in Tennessee age faster than average due to the intense heat and humidity cycles. After 10 years, efficiency drops dramatically and repair costs often exceed replacement value.
If you're calling for repairs multiple times per season, the cost adds up fast. A new system will pay for itself in 2-3 years through lower energy bills and zero repair bills.
An aging system loses efficiency every year. A new high-efficiency unit (16+ SEER) can cut your cooling costs by 30-50% compared to a 10-year-old system.
R-22 (Freon) has been phased out and the cost to recharge is now $100+ per pound. Upgrading to a modern R-410A or R-32 system eliminates this ongoing cost entirely.
Hot and cold spots throughout the house usually indicate ductwork issues or a failing system that can no longer distribute air properly — new systems with variable speed tech solve this.
Modern variable-speed AC systems run whisper-quiet. If your system sounds like a freight train, it's a sign the internal components are worn and the system is on its last legs.
