7 Signs It's Time to Replace Your Air Conditioner
Every air conditioner reaches a point where repair stops making sense. Here's how Tennessee homeowners can tell when it's time for AC replacement.
1. Your system is over 12 years old
Most central air conditioners last 12–15 years in the Tennessee climate. Past that, efficiency drops and major parts begin to fail.
2. It uses R-22 refrigerant
R-22 (Freon) production ended in 2020. Recharging an R-22 system is extremely expensive, and a leak often makes replacement the smart move.
3. Repairs are getting frequent and expensive
Use the "$5,000 rule": multiply the repair cost by the system's age. Over $5,000? Replace.
4. Energy bills keep climbing
If usage hasn't changed but bills have, your system is losing efficiency. New systems with SEER2 ratings of 15–20+ can cut cooling costs by a third.
5. Uneven cooling and humidity
Hot rooms, sticky air and constant running suggest an undersized, oversized or worn-out system. New variable-speed systems fix both.
6. Loud noises
Grinding, screeching or banging point to major mechanical wear. Learn more about compressor repair before deciding.
7. You're planning to sell or renovate
A new HVAC system is a selling point and can be sized correctly for an addition.
