Signs Your AC Worked Too Hard This Summer (and What to Do About It
Summer in Shelby, NC can be tough on your air conditioner. Long, hot days mean your system has to work extra hard to keep your home cool and comfortable. By the time fall rolls around, your AC may be showing signs of wear and tear. Recognizing these issues early can save you from costly breakdowns and prepare your system for the seasons ahead. Here are a few common signs your AC worked overtime this summer—and what you should do about it:
1. Higher Energy Bills
Did your power bills spike this summer? An overworked AC often runs longer cycles and uses more energy. While some increase is normal during hotter months, a big jump could mean your system isn’t running efficiently.
What to do: Have your system inspected and consider scheduling a tune-up to restore efficiency.
2. Uneven Cooling
If some rooms felt cooler than others, it’s a sign your AC may have struggled to keep up. Duct leaks, clogged filters, or weak airflow can cause this imbalance.
What to do: Change your air filters and have your ducts inspected for leaks or blockages.
3. Strange Noises or Smells
Grinding, banging, or musty odors coming from your unit aren’t normal. These can point to mechanical wear, motor issues, or even mold growth from excess moisture.
What to do: Call a professional right away to prevent small problems from turning into expensive repairs.
4. More Frequent Repairs
If you found yourself calling for AC service multiple times this summer, it’s a sign your system may be reaching the end of its life.
What to do: Talk to a trusted technician about whether repair or replacement is the better investment.
5. Weak Airflow
If the air coming out of your vents felt weak—even when the thermostat was set low—your AC may be struggling with a failing blower motor or other worn parts.
What to do: Have your system inspected before fall to prevent a complete breakdown.
