Let’s break down the most common signs that it’s time to replace your air conditioner—and why homeowners in Buffalo, NY and the surrounding areas turn to us when it’s time to upgrade their home comfort.

How Long Should an Air Conditioner Last?

Most central air conditioning systems last 10 to 15 years when properly maintained. Ductless mini-split systems can often last even longer, up to 20 years. But once your system nears the end of its lifespan, it becomes more prone to breakdowns, inefficiency, and expensive repairs.

6 Signs It’s Time to Replace Your Air Conditioner

1. Frequent Breakdowns

Are you calling for AC repairs every summer? If repair costs are piling up, it may be more cost-effective to invest in a new system.

2. Soaring Energy Bills

Older systems often have lower SEER (Seasonal Energy Efficiency Ratio) ratings, which means they use more electricity. A new, energy-efficient unit can dramatically lower your monthly utility costs.

3. Uneven Cooling or Poor Airflow

If some rooms are freezing while others stay warm, or if you’re noticing weak airflow, your system might not be functioning properly anymore.

4. It Still Uses R-22 Refrigerant

If your system was installed before 2010, it may use R-22 (Freon), which is now banned in the U.S. for environmental reasons. Refilling these systems is costly and unsustainable.

5. Strange Noises or Odors

Clanking, buzzing, or musty smells coming from your AC are all signs of major internal issues. These are often indicators that replacement is a smarter move than repair.

6. Excess Humidity Indoors

Your AC should not only cool but also help regulate humidity. If your home feels damp or sticky even when the AC is running, that’s a red flag.

The $5,000 Rule: Should You Repair or Replace?

Here’s a handy tip: Multiply the cost of the repair by the age of your system. If the number exceeds $5,000, replacement is generally the better long-term value. For example, a $600 repair on a 10-year-old unit equals $6,000—that money could be better spent on a new, high-efficiency system.
