How to Tell if Your AC Can Make It Through the Rest of the Season In DuPage county IL



Signs You May Need AC Repair, Maintenance, or Replacement in Naperville, Wheaton, Glen Ellyn, Lombard, and Surrounding DuPage County Areas

August is here, and while cooler weather is on the horizon, DuPage County residents know the summer heat isn’t over yet. Hot days and humid nights can stretch into September—which means your air conditioner still has to perform.

But if your system is showing signs of strain, now is the time to act. Whether it’s AC repair, AC maintenance, or planning for an air conditioner replacement, getting ahead of the problem can save you from a costly breakdown.

Here are five signs your AC might not make it to fall without professional air conditioning service:

1. Blowing Warm or Weak Air

If you’re in Naperville, Wheaton, or Glen Ellyn and your AC is only putting out lukewarm air—or the airflow is weak—it could be a sign of low refrigerant, dirty coils, or a failing compressor. Professional AC repair can quickly pinpoint the issue and restore comfort.

2. Strange Noises or Odors

Grinding, banging, or squealing noises from your air conditioner, or musty and burning smells from vents in Lombard, Elmhurst, and Downers Grove, often mean trouble. These are warning signs that you need air conditioning maintenance or repair before the problem gets worse.

3. Rising Energy Bills

If your August electric bill is higher than July’s, and your usage hasn’t changed, your system could be running too long to keep up. This is common in aging units and can often be improved with AC maintenance or a strategic air conditioner replacement.

4. Frequent On-and-Off Cycling

Short cycling wastes energy and increases wear on your system. In homes across Carol Stream, Villa Park, and Addison, it’s often caused by electrical issues, low refrigerant, or poor sizing. A quick AC service call can stop the problem before it causes a breakdown.

5. Your System Is 10–15 Years Old

Even with regular air conditioning maintenance, older systems eventually lose efficiency. If your AC in Lisle, Oak Brook, or Westmont is over a decade old and showing other issues from this list, it may be time to consider an air conditioner replacement before next summer.
