These Cooling Misconceptions Are Common. Learn the Truth.

Since air-conditioning costs make up the larger part of our utility expenses here in Yuma, it makes sense for people to want to look for ways to keep summer cooling costs down. But the problem is some of the tips out there are outright myths that can cost you more money. Let’s look at some of the most common cooling misconceptions.

1. It’s more energy-efficient to keep your home at a steady temperature.

The difference between the temperature you set your thermostat to and the temperature outside affects your cooling system’s energy usage. The bigger this temperature difference is, the more energy your air conditioner will use trying to maintain the thermostat temperature.

Let’s say the temperature outside is 85 degrees. Your system will use more energy to maintain 72 degrees versus 76 degrees. For that reason, it’s best to set a programmable thermostat to raise the temperature in your home when you’re not around. That can dramatically lower your energy usage.

2. Ceiling fans cool rooms.

Scientifically, they don’t. These fans circulate air, creating a breeze that makes you feel cooler due to sweat evaporating from your skin. They can also help distribute conditioned air better. Ceiling fans don’t thermally affect your home’s air. You’re wasting energy by leaving them on when you leave a room.

3. Cranking your thermostat way down cools your home faster.

A central air conditioner is designed to function at a fairly constant pace. Choosing an extreme temperature won’t make it hurry. And don’t forget that your system just stays on for as long as needed to get your home to the desired temperature, then it turns off. Putting your thermostat way down wastes energy, and you may end up with a frigid house if you don’t remember to readjust the thermostat as soon as it hits a comfortable temperature.

Be sure to save on air-conditioning costs by avoiding these cooling misconceptions. For all your cooling needs in the Yuma area, don’t hesitate to contact us at Hansberger Refrigeration and Electric Company.
