Best AC Settings for When You’re on Vacation

Man is Adjusting a  temperature  on the thermostat in the living room.

Leaving for vacation is exciting, but before you walk out the door, don’t forget to prepare your home’s air conditioning system. Setting the AC properly can protect your home from heat-related damage, keep pets safe, and even help lower your energy bills while away.

Today, the comfort specialists at Del-Air Plumbing, Air Conditioning, Electric explain what temperature is best to keep your thermostat at while away on vacation.

The Hidden Dangers of Turning Off Your AC Completely

Turning off your air conditioner entirely might seem like a good way to save energy, but it can backfire. When indoor temperatures climb too high, moisture builds up, increasing the risk of mold and mildew — a constant threat in Florida’s hot, humid climate.

Furniture, wood flooring, and electronics can also warp or become damaged due to high heat and humidity. To protect your home’s interior and structure, it’s best to keep your AC running at a higher temperature rather than switching it off.

Finding the Sweet Spot: Why Not Too Hot? Why Not Too Cold?

The goal is to balance energy efficiency with indoor protection. Most experts recommend setting your thermostat between 78 degrees to 82 degrees Fahrenheit while on vacation. This range keeps your home comfortably above your usual setting but still cool enough to prevent heat and humidity damage.

A simple rule of thumb is to raise the thermostat 4 to 7 degrees above your usual setting, depending on how long you’ll be gone and how hot the weather will be.

Smart Thermostats: Your Remote Climate Control Companion

A smart thermostat makes managing your home’s temperature while you’re away easy and efficient. With features like scheduling, real-time remote control, geofencing, and energy use tracking, you can ensure your house isn’t too warm or cold, no matter where you are. Smart thermostats offer excellent control and vacation mode settings to help you optimize energy savings without sacrificing comfort.

Beyond the Thermostat: Preparing Your Home for Vacation Heat

Help your AC work smarter, not harder. Simple steps can keep your home cooler and reduce strain on your system:

  • Close blinds and curtains
  • Seal windows and doors
  • Set ceiling fans to rotate counterclockwise
  • Unplug nonessential electronics
  • Ensure vents are open and unobstructed

Considering Alternatives: When Fans & Dehumidifiers Can Help

In high-humidity climates like Florida, portable dehumidifiers can prevent moisture damage even when the thermostat is set higher. Fans can also circulate air and assist in keeping temperatures stable. While they shouldn’t replace your AC, these appliances can support your cooling strategy and offer a useful backup layer of protection.

Protecting Your Furry Friends: Don’t Forget Your Pets!

Maintaining a safe indoor temperature is non-negotiable if your pets stay behind. Never set the thermostat above 80 degrees when animals are home. Make sure they have ample fresh water, ventilated space, and, if possible, someone to check in while you’re gone.

Enjoy Your Trip With Peace of Mind

Setting your AC correctly before leaving can make a big difference in protecting your home, cutting utility costs, and keeping your pets comfortable. With smart planning and a few simple steps, you can leave worry behind and fully enjoy your time away.

This was my first experience with Del-Air and they were prompt, professional, and knowledgeable. They were able to get me in on the same day for a maintenance visit, which I wasn’t expecting but very much appreciated. The office staff was pleasant and so was the technician that came out to service my air conditioners. Thanks…
