3 Signs You Should Replace Your AC System in Highland Park, IL

July 20, 2025

A reliable air conditioner is a must if you want to stay comfortable in Highland Park, IL, in the summer. However, it’s not always easy to tell when it’s time to replace your home’s AC system. To help, here are three signs it’s time to replace your air conditioner:

Your AC System Is More Than 15 Years Old

Generally, you can expect about 15 years of reliable service from a well-maintained air conditioner. If yours is older than that, it’s a good idea to consider replacing it. If it hasn’t already become unreliable, your AC system’s age means it’ll likely start to fail soon.

Your Cooling Costs Keep Rising

With each passing year, electricity costs continue rising. Simultaneously, wear and tear contribute to a decline in the efficiency of your existing AC system. The result is that each subsequent cooling season costs you more than the previous one.

Installing a new air conditioner can help you cut your cooling bills significantly. For example, a minimally efficient AC system installed in 2015 would have a seasonal energy efficiency ratio (SEER) of 13, whereas today’s minimum is 14. That means a new air conditioner will run at least 7.69% more efficiently than your existing system.

You’re Facing a Massive AC Repair Bill

Finally, if your air conditioner breaks down and the repair estimate seems high, an AC replacement may be a more cost-effective investment. Depending on the age of your AC system, there are some repair needs that raise immediate red flags. One is if your AC system needs a new compressor, which is rarely worth the cost.

For other repairs, multiply the estimated repair cost by your AC system’s age. If the number exceeds $5,000, an AC replacement is a better option. The formula shows that your air conditioner will likely fail again before you get your money’s worth.
