One of the clearest indications that air conditioning replacement may be in order is increasing cooling costs. It’s normal for power bills to rise during the warmer months when the air conditioner runs more. They shouldn’t surge excessively, though.

If your electric bills are growing out of control, the air conditioner could be at fault. AC system efficiency decreases over time. That’s particularly true if routine maintenance has been ignored. Air conditioners end up having to work harder and run longer to keep a house cool. Even then, they may not be very effective. Higher cooling costs are definitive signs that it may be time for air conditioning and heating replacement.
