When summer heat rises in Des Moines, IA, it’s tempting to turn your thermostat way down. Many homeowners set their thermostat settings in summer as low as they can tolerate, hoping for faster relief. Unfortunately, this pushes your air conditioner past its limits, leads to system strain, and wastes energy.
Raise Your Thermostat Settings Instead
You need your air conditioner to keep your home comfortable during the hottest months. But setting your thermostat too low can cause your AC to overwork. This often results in higher energy bills, short cycling, and costly AC repairs. One of the most common signs of an AC overworking is that it runs constantly without cooling effectively. To avoid these issues, it’s best to follow energy-efficient AC settings and avoid pushing your system too hard.
The Temperature Differential
Your air conditioner can only cool about 20°F below the outdoor temperature—this is called the temperature differential. For example, if it’s 95°F outside and you set your thermostat to 68°F, your system will run endlessly trying to achieve something it physically can’t. This leads to system wear, overheating, or frozen coils, which means your air conditioner might shut down or stop cooling altogether.
Homeowners often ask us, “Why is my AC always running?” or “Why is my AC freezing up?” The answer is often simple: the thermostat is set too low for the outdoor temperature.
The Perfect Temperature
Around 70°F is considered the ideal thermostat temperature during peak summer heat. It’s cool enough to stay comfortable but warm enough to keep your system running efficiently. Lower settings increase the risk of frozen coils, which lead to AC breakdowns and inefficient cooling. If you’re noticing inconsistent temperatures or suspect your air conditioner is freezing up, the thermostat may be to blame.
