How Programmable Thermostats Help You Stay Comfortable and Save Energy This Summer

June is when summer heat really begins to settle into Northwest Indiana. Temperatures rise quickly, humidity increases, and cooling systems start running much more frequently. It’s also the time when many homeowners notice higher energy bills and realize their HVAC systems are working harder than expected.

One of the easiest and most effective ways to improve comfort and control summertime energy costs is by upgrading to a programmable thermostat. These devices give you far more control over your home’s temperature settings and help your cooling system operate more efficiently throughout the day.

Why Programmable Thermostats Matter in Summer

Programmable thermostats allow you to set automatic temperature adjustments based on your daily routine. When used correctly, they reduce unnecessary cooling during times you’re asleep, away from home, or during naturally cooler parts of the day.

The most effective strategy is called a “setback," which means raising your thermostat a few degrees during lower‑demand periods. According to the U.S. Department of Energy, homeowners can save up to 10% annually on heating and cooling costs by adjusting thermostat settings for part of the day.

A common misconception is that setting the thermostat extremely low cools the home faster. In reality, your AC cools at the same speed no matter the setting—lowering it too far only forces the system to run longer, increasing energy usage and wear

Try Pre-Cooling on Hot Days

Another helpful strategy in Northwest Indiana’s summer heat is pre-cooling—slightly lowering the temperature earlier in the day while outdoor temperatures are still manageable. This reduces strain on your AC during the peak afternoon heat.

Programmable and smart thermostats make pre-cooling easy by automating these adjustments for you.

Supplement With Routine AC Maintenance

Even the best thermostat can’t make up for a neglected air conditioner. Early summer is a critical time to ensure your system is clean and running efficiently—especially with cottonwood season typically lasting through mid‑June.

Check Your Air Filter Regularly

Dirty air filters restrict airflow, reduce efficiency, and can lead to preventable mechanical issues. During the summer, check filters monthly and replace them when needed—especially in homes with pets or higher dust levels.

Watch for Cottonwood Buildup

In Northwest Indiana, cottonwood seeds often cling to outdoor AC units and clog condenser coils. This buildup forces your system to run longer and work harder.

Signs of cottonwood issues include:

• Weak airflow
• Long cooling cycles
• Higher energy bills
• Reduced cooling performance

Surface debris can be gently rinsed away, but deeper cleaning should be handled by a licensed HVAC professional.

Keep Your Outdoor Unit Clear

Good airflow is essential. Make sure the area around your outdoor unit stays free of leaves, overgrown plants, and debris. A clear space of at least two feet around the unit helps it operate efficiently.

When to Call for Professional Service

If your AC is struggling, unusual symptoms often appear before the heat peaks. Contact a professional if you notice:

• Warm air from vents
• Weak or uneven airflow
• Strange noises such as rattling or grinding
• Frequent cycling
• Sudden increases in energy bills
• Musty or burning odors

These issues may indicate refrigerant problems, electrical concerns, airflow restrictions, or thermostat malfunctions.
