Why Your Energy Bill Jumps in Summer — Is Your AC to Blame?

If your summer utility bill made your jaw drop, you’re not alone. Across Olathe and Johnson County, homeowners often see big spikes in energy costs during hot Kansas summers. While part of that is due to higher demand, your air conditioner may be the real culprit.

At Jack Harrison Heating & Air Conditioning, we’ve helped countless families lower their energy bills with maintenance, repairs, and energy-efficient upgrades.

We have also completed the steps to become an official Evergy-Authorized Trade Ally so that we can help you, our customers, apply for the Evergy utility rebates with your new AC purchase and get you some money back.

Here’s why your bills may be soaring — and what you can do about it.

When the outside temperature climbs into the 90s, your AC has to run longer to keep up. If it’s older, dirty, or improperly sized, it will struggle even more — driving up costs.

✅ Solution: Annual tune-ups keep your system running efficiently and reduce wasted energy.

Restricted airflow forces your AC to work harder. Dirty filters or clogged coils are among the easiest-to-fix causes of high energy bills.

✅ Solution: Change filters regularly and schedule seasonal maintenance to clean coils.

Up to 30% of cooled air can escape through leaky ducts. That means you’re paying for conditioned air that never reaches your living space.

✅ Solution: Have your ducts inspected and sealed to prevent waste.

If your AC is 10–15 years old, it’s likely using much more energy than a modern system. Newer models with higher SEER2 ratings are designed to cool effectively while using far less electricity.

✅ Solution: Consider upgrading — especially while rebates and financing are available.

Even the best AC can’t overcome drafty windows, poorly sealed doors, or under-insulated attics.

✅ Solution: Improve your home’s insulation and sealing for maximum efficiency.

Right now, Kansas homeowners can save with Evergy Heating and Cooling rebates on energy-efficient HVAC systems — but these incentives won’t last forever. By upgrading to a new high-efficiency AC with Jack Harrison Heating & Air Conditioning, you’ll:

• Lower your monthly bills.

• Enjoy more consistent comfort.

If your energy bill has you scratching your head, your AC may be costing you more than it should. Whether it’s maintenance, ductwork, or a replacement, we’re here to help.
