Your air conditioner will start giving you small signs that it’s failing. Here are five of the most common ones.

1. You often need repairs. As your air conditioner ages, it becomes less energy efficient and more prone to problems. If we’re often at your home for air conditioning repairs, you might need a new air conditioner.

2. Repairs are more than half the cost of a new air conditioner.  When they’re more than half the cost of a new air conditioner, you should replace yours.

3. Your air conditioner is 15-20 years old. 

4. Your air conditioner runs on R22 refrigerant. If your air conditioner was installed before 2010, it potentially runs on R22 Refrigerant. This refrigerant is discontinued due to its negative effects on the ozone layer. Because R22 has been discontinued, fixing a refrigerant leak would be significant.

5. You want to reduce your cooling costs. Selecting an ENERGY STAR® air conditioner and pairing it with a smart thermostat is a wise way to conserve on energy costs. Even if you’re replacing an air conditioner that’s merely 10 years old, the Department of Energy says a more efficient model could save you 20–40% on electrical expenses.
