Thermostat Temperatures for Efficient Louisville Cooling

Heat and humidity make the summer months feel unbearably hot inside your Louisville home. Programmable thermostats are supposed to help you save energy, but they aren’t useful when you don’t know the right way to set your thermostat in the summer.

When the air is hot, your first thought may be to adjust the thermostat temperature several degrees below the normal setting to cool off each room inside your house. This settings strategy does nothing for energy efficiency or to help you save money. Instead, learn the best thermostat temperature setting for summer and tips to set a programmable thermostat for better heating and cooling efficiency.

Jarboe’s Heating, Cooling & Plumbing aims to help you cut your energy bill using your programmable thermostat in summer. Our tips provide energy-efficient temperature settings that allow you to increase savings on bills without feeling like your home has too much heat.

What Temperature Should I Set on My Programmable Thermostat?

Homeowners regularly ask how they should set my thermostat for air conditioning without breaking the bank. The best temperature to set thermostats really depends on your preferences and goals. If your focus is using less energy, you will set the thermostat higher than someone who values comfort overall. Just remember, just because you want to save energy doesn’t mean you can’t cool your home to a comfortable temperature, too.

The U.S. Department of Energy states the recommended thermostat temperature settings for the greatest energy efficiency is 78 degrees while at home, 82 degrees while you sleep, and 85 degrees when everyone is out of the house.

The Department of Energy promotes the same strategy to set the thermostat in the winter, too. Winter heating settings offer highest efficiency at 68 F when home and 7 to 10 degrees higher when you sleep or leave the house. Anytime you have the opportunity for turning your thermostat up or down 10 degrees or more (depending on if it is summer or winter), for periods of 8 hours or more, you are able to save as much as 10% on energy bills.

What Temperature Is Comfortable and Efficient?

Many people feel turning the thermostat to 78 robs the house of any cool air and comfortable temperature, as it simply feels too warm. That’s completely ok! If you prefer a cooler room for relaxing, setting your thermostat a few degrees lower than 78 F won’t erase all energy savings.

Setting your thermostat generates energy savings and savings on bills whenever you choose a temperature that is higher than what you’d pick on a normal day by a few degrees. Using a thermostat setting that is degrees higher than normal means your air conditioning unit doesn’t have to provide as much cooling. It doesn’t need as much energy, so the cool air it does deliver is more efficient.

78 degrees isn’t for everyone – set the thermostat at whatever temperature you find comfortable. The ideal temperature is different from one person to the next, but everyone can use the same thermostat settings principles to save money on air conditioner use.

How Do Higher Temperatures Save Money?

Anytime you set your thermostat to a temperature above 72 degrees, you save around 3% for every degree over 72 you set the thermostat. Choosing a higher temperature to set on programmable thermostats means indoor air is closer in temperature to outdoor air than compared to the lower temperature you used to set the thermostat in the summer. Closing this gap reduces home cooling load and air conditioning equipment doesn’t need as much energy to provide smaller volumes of cool air.

Set Your Thermostat to Stay Comfortable and Save

If you are used to a normal air conditioner setting around 70 degrees, jumping immediately to thermostat settings of 75 degrees is likely going to feel too warm. When you feel hot, it’s easy to become discouraged with your efforts to schedule programmable thermostats for energy efficiency.

Instead of jumping directly to what you think may be the best temperature, take small steps. Set your programmable thermostat one degree higher each day until you reach the best temperature to stay cool without feeling too much heat.

Maintain Cooling Temperatures During a Heat Wave

The Louisville summer can bring some pretty extreme heat. Days such as these disrupt your air conditioner and savings efforts because a larger difference exists between the temperature of heating outdoors and cold temperatures from your air conditioner inside.

  • When you want to achieve a temperature difference as high as 20 degrees, it’s no problem for a normal air conditioner. When outdoor temperatures force a temperature differential higher than 20 degrees, the system simply cannot adjust no matter how you schedule your programmable thermostat.

  • Because your air conditioner cannot make the house any cooler, it’s up to you to put tips into place to manage heat for your cooling system – try these moves:

  • Humidity is often more of a problem than heat, and it makes the heat worse! When humidity levels are high, more moisture remains in the air and moisture is very efficient at holding heat. Add a dehumidifier to your HVAC system and remove humidity during the summer months. Lower humidity helps air feel cooler.

  • Prevent direct sunlight exposure in the home so a room doesn’t gain new heat from outside. Curtains, blinds, insulated shades, and other window coverings should be closed during the day to block direct sunlight and heat energy from entering the home.

  • Stop hot outdoor air from moving into the home by sealing air leaks. Gaps around door frames and windows, damage to the foundation, and other issues create paths for heat to go indoors as well as for cold air to escape the home. Weatherstripping and caulk are easy to apply and provide excellent air sealing when used correctly.

  • Set a ceiling fan to run while you are in the room. The downdraft created by the counterclockwise fan rotation creates a wind chill that evaporates moisture from your skin so you don’t feel as hot.

  • Save heat-producing tasks for early morning or late evening hours. Showers, baths, laundry, cooking, and baking add heat to the home and raise indoor temperatures.

  • Set the air conditioner fan to run throughout the day, providing constant air circulation. Thermostat settings control the fan, so switch them from AUTO to ON and the fan will help keep air moving in your home all hours of the day.
