The Top Signs It's Time to Replace Your AC Unit

When summer hits in Livonia, a reliable air conditioner is essential to staying comfortable indoors. But like all home appliances, AC units don’t last forever. If your cooling system has been struggling to keep up, it might be time to consider a replacement. At Kelley Brothers, we specialize in helping Michigan homeowners determine whether a repair or full replacement is the smarter, more cost-effective choice. Here are the top signs it’s time to replace your AC unit.

1. Your AC Is Over 10–15 Years Old

The average lifespan of an air conditioning unit is around 10 to 15 years. If yours is in that range—or older—chances are it’s not operating as efficiently as newer models. Over time, wear and tear adds up, leading to more frequent repairs and higher energy consumption. If your unit is nearing the end of its expected life, now is the perfect time to upgrade to a more efficient, reliable system.

2. Frequent and Costly Repairs

Have you found yourself calling for AC repairs more often than usual? If the cost of repairs is stacking up—or if the repair cost is more than half the price of a new unit—it’s usually more economical to replace the system altogether. At Kelley Brothers, our experienced HVAC technicians can help you weigh your options and make an informed decision.

3. Inconsistent Cooling or Poor Airflow

If your home feels stuffy, or some rooms are cooler than others, your air conditioner may be struggling to maintain proper airflow. Ductwork issues can sometimes be the cause, but in many cases, an outdated AC unit simply can’t distribute air evenly throughout your home. Upgrading to a modern system ensures more even cooling and better overall comfort.

4. Rising Energy Bills

Have your utility bills increased without a change in your usage habits? An inefficient AC unit often works harder to maintain your desired temperature, resulting in higher energy consumption. Today’s high-efficiency air conditioners are designed to reduce energy waste, saving you money on monthly bills while keeping your home cool.

5. Strange Noises or Odors

Unusual sounds like grinding, banging, or squealing can indicate internal damage. Similarly, musty or burning smells may signal mold in the system or electrical issues. These problems shouldn’t be ignored. Replacing your unit can restore peace and comfort to your home while eliminating safety hazards.
