At Tom Schaefer Plumbing, Heating & Cooling, we understand the importance of a reliable air conditioning system for your comfort. Recognizing the signs that indicate it’s time to replace your air conditioner can help you avoid unexpected breakdowns and maintain a comfortable home environment.

How Long Does an Air Conditioner Last?
Most air conditioning systems have a lifespan of 10 to 15 years, depending on maintenance and usage. If your AC is approaching or exceeding this range, replacement may be more cost-effective than frequent repairs.
Key Signs It’s Time to Replace Your Air Conditioner
Frequent Repairs
If your AC system requires frequent service calls, the cumulative repair costs may exceed the price of a new unit. Older systems tend to break down more often, leading to costly emergency repairs.
Rising Energy Bills
A sudden spike in energy costs may indicate that your AC is running inefficiently. Newer models are designed with higher energy efficiency, helping reduce your monthly bills.
Uneven Cooling or Weak Airflow
If some rooms are significantly warmer than others, your AC may no longer be distributing air properly. Poor airflow can result from aging ductwork, a failing compressor, or clogged filters.
Strange Noises or Odors
- Unusual Sounds: Grinding, squealing, or banging noises may indicate worn-out or failing components.
- Unpleasant Smells: Musty or burning smells can signal mold buildup or electrical issues that require immediate attention.
Excess Humidity or Moisture
Your AC should regulate indoor humidity levels effectively. If you notice excessive humidity, your system may not be functioning correctly. Water leaks around the unit can indicate a refrigerant issue or drainage problem.
Your AC Uses R-22 Refrigerant
Older systems that use R-22 refrigerant (phased out due to environmental concerns) can be expensive to maintain and should be replaced with newer, eco-friendly models.
