Top 5 Signs Your AC Might Not Survive the Summer

Person too warm indoors due to AC not working

Don’t Wait for a 95° Day to Find Out

Picture this: It’s the hottest week of the year in Central Ohio. You’re trying to relax, but your AC is blowing warm air—or worse, not blowing anything at all.

Every summer, Sears Heating and Cooling gets flooded with emergency calls from customers caught off guard by an unexpected AC failure. The good news? Most of these breakdowns gave warning signs well before the system quit for good.

Here are the top 5 signs your AC might not make it through the season—and what to do before it’s too late.

  1. It’s Blowing Warm or Weak Air

If your AC isn’t pumping out strong, cold air like it used to, something’s not right. Common culprits include:

It may still “run,” but it’s wasting energy and not doing its job—an early sign it could fail under pressure.

  1. Strange Noises

Your AC shouldn’t grind, rattle, squeal, or clunk. These sounds can point to:

Bottom line: If your AC sounds like it’s struggling—it probably is.

  1. It’s Short-Cycling or Running Constantly

Short-cycling (starting and stopping frequently) or running all day without reaching your desired temp signals trouble. This could mean:

Both behaviors put unnecessary strain on your system—and your electric bill.

  1. Your Energy Bills Are Suddenly Spiking

If your usage habits haven’t changed, but your energy bills have jumped, your AC may be working overtime to compensate for:

A mid-season breakdown often starts with a quiet spike in your bill.

  1. Your Unit Is Over 12–15 Years Old

Even well-maintained AC units have a lifespan. If yours is over a decade old and showing any of the signs above, it’s time to plan ahead. Waiting until it fails could mean:

Don’t Wait for a Total Breakdown

A pre-summer inspection or service call can catch issues early—and possibly extend the life of your current system. Even if your unit is near the end, replacing it on your terms (before peak season demand) is always smarter than waiting for an emergency.
