What should you set your thermostat to when you’re on vacation? If you’re planning your next summer vacation, amidst all the excitement of travel arrangements and creating the perfect to-do list, it’s crucial not to forget about your home’s HVAC system. Your air conditioner plays a pivotal role in maintaining a comfortable home, but when you’re away, finding the right thermostat settings for an empty house can ensure lower energy costs and peace of mind.

What Should You Set Your Thermostat to When You’re on Vacation?

What to do if You Don’t Have a Smart Thermostat

When you’re heading out for a vacation and don’t have the convenience of a programmable thermostat, setting manual thermostats properly is still essential to conserve energy and protect your home. Here’s a simple guide to help you set your thermostat before you leave:

1. Raise the Temperature

Set your thermostat to a higher temperature than usual to save money on energy bills. A good rule of thumb is to set it around 80-85°F. This will prevent your air conditioner from running unnecessarily while still keeping your home from becoming excessively hot. Remember to look ahead at the weather forecast. You’ll want to keep your home’s interior at a cool enough temperature that outside extreme temperatures won’t cause any damage in your extended absence.

2. Close Curtains and Blinds

Before leaving, close curtains and blinds to block out the hot sun. This helps maintain a cooler indoor temperature and reduces the workload on your air conditioning system.

3. Secure Windows and Doors

Ensure all windows and exterior doors are closed and securely locked to prevent warm air from entering your home.

4. Turn Off Non-Essential Appliances

Unplug electronics and appliances that won’t be in use while you’re away. This reduces unnecessary energy consumption and lowers the overall heat generated inside your home.

Setting a Smart Thermostat When You Leave for Vacation

Smart thermostats are revolutionizing the way we interact with our HVAC systems. Wi-Fi thermostat, or smart thermostat, offers programmable features that allow you to adjust your home’s temperature remotely using smartphone apps or internet-enabled devices. This technology not only enhances energy efficiency but also provides the flexibility to create the ideal indoor environment, even when you’re miles away.

The Ideal Thermostat Setting for Vacation

When setting your thermostat for a vacation on the summer, it’s recommended to set it higher than usual to conserve energy while preventing excessive heat buildup. A good rule of thumb is to set the temperature around 85°F, which will keep your home cool without overworking your air conditioning system. With a smart thermostat, schedule a daytime temperature of 80°F and a nighttime temperature of 85°F.

Benefits of Smart Thermostats

Smart thermostats offer several advantages when it comes to managing your HVAC system during vacations. They allow you to create custom schedules based to adjust the temperature during the day vs the nighttime for the best thermostat settings no matter the time of day. Since we have more extreme heat outside during the day, you may want your home slightly cooler to protect your home from excess humidity. At night, a slightly warmer temperature should be fine to save energy. Some smart thermostat models feature vacation mode settings, which temporarily adjust your home’s temperature to maximize energy savings while you’re away.

A wi-fi controlled AC unit also allows you to change your thermostat settings while you’re not home in case there are higher-than-expected temperature issues and you need to adjust your cooling system.
