When you’re preparing for a much-needed vacation, your to-do list can get pretty long. From packing your bags to securing your home, there’s always one lingering question many homeowners in Newnan, GA face before walking out the door: Should I leave the air conditioner on while I’m away?
With Georgia’s mix of humid summers, mild winters, and unpredictable temperature swings, this isn’t a one-size-fits-all decision. Your HVAC system plays a crucial role not just in comfort, but also in protecting your home while you’re gone. Let’s explore the pros and cons, the risks of shutting it off completely, energy-saving strategies, and what local homeowners need to know before heading out of town.
Understanding the Newnan, GA Climate and Why It Matters
Newnan, like much of central Georgia, experiences long periods of heat and humidity. Even outside the peak summer months, temperatures in the region can climb into the 80s and 90s with relative humidity levels that often exceed 70%. High humidity isn’t just uncomfortable—it can also lead to mold, mildew, and other damage inside your home if not properly managed.
Because of this, HVAC decisions in Newnan aren’t only about staying cool—they’re also about keeping your home safe and structurally sound.
The Risks of Turning Off Your AC Completely
While it might be tempting to turn off your AC system completely to save on energy costs while you’re gone, this can often do more harm than good—especially in climates like Newnan’s.
1. Heat and Humidity Can Damage Your Home
When air conditioning is off for extended periods, indoor temperatures can climb quickly, sometimes reaching 90°F or higher. Combined with Georgia’s naturally high humidity, this creates ideal conditions for moisture buildup and mold growth. Items like wood furniture, hardwood floors, and electronics can warp or degrade in such an environment.
2. Appliances and Systems May Overheat
If you have refrigerators, freezers, or other appliances running while you’re away, a hot interior can strain those systems. Some electronics and home equipment can malfunction or even suffer permanent damage due to excessive heat.
3. Your Indoor Air Quality May Suffer
Without AC running, there’s no filtration or ventilation happening. Dust, allergens, and pollutants can linger in stagnant air, making your return home less pleasant—and potentially triggering allergies or respiratory discomfort.
4. Increased Pest Activity
Warm, moist environments are a breeding ground for bugs and pests. Cockroaches, ants, and silverfish thrive in heat and humidity, especially in closed-off spaces. Keeping the AC on at a higher setting can deter these unwanted visitors.
Benefits of Leaving the AC On—But Adjusted
The good news? You don’t need to keep your home icy cold while you’re away. Instead, you can raise the thermostat to maintain a balance between energy savings and home protection.
1. Protects Your Home’s Interior
Keeping indoor temperatures in a moderate range (typically around 80–85°F) helps maintain air circulation and humidity control. It’s cool enough to prevent damage but warm enough to conserve energy.
2. Reduces Humidity
Most modern AC systems in Newnan are equipped with built-in dehumidification features. Even when set at higher temperatures, your system can still reduce indoor humidity, protecting furniture, floors, and electronics.
3. Prevents HVAC System Shock
HVAC systems function best when they’re run regularly. Shutting them off entirely for a week or more and then cranking them back up can lead to system shock or sudden strain—especially if the system already has wear and tear.
4. Peace of Mind
Knowing your home is protected from extreme heat and moisture allows you to enjoy your vacation with fewer worries.
Energy-Saving Tips While You’re Away
Leaving your AC on doesn’t mean resigning yourself to high energy bills. There are several smart and simple strategies that allow you to save energy while still protecting your home.
1. Raise the Thermostat
Set your thermostat to around 80–85°F before leaving. This temperature is high enough to reduce energy usage but still low enough to keep humidity in check.
2. Use a Programmable or Smart Thermostat
Smart thermostats are incredibly helpful for travelers. You can monitor and adjust temperatures remotely and even receive alerts if your system malfunctions. Some models also have vacation or “away” settings that optimize indoor conditions while conserving energy.
3. Close Blinds and Curtains
Blocking out sunlight can help keep your home cooler naturally. Closed blinds and curtains reduce heat gain, especially on south- and west-facing windows.
4. Seal Leaks and Insulate
Ensure windows, doors, and attic spaces are sealed and insulated to prevent warm air from entering and cool air from escaping. This small step can significantly reduce the strain on your HVAC system.
5. Unplug Electronics
Even when off, many appliances draw power. Unplug TVs, computers, and kitchen appliances to minimize heat generation and energy consumption.
Should You Use the “Away” or “Eco” Mode?
Many modern AC units and thermostats have an “away” or “eco” mode, which automatically sets the system to a more energy-efficient temperature. In humid regions like Newnan, it’s important to check whether these modes also control humidity levels.
When in doubt, consult with your HVAC technician to make sure these features are configured properly. Some systems may prioritize energy savings at the expense of humidity control, which can be risky in Georgia’s climate.
How Long Will You Be Gone? Duration Matters
If you’re going away for a few days, a slightly higher indoor temperature is perfectly fine. But if you’re taking an extended trip—such as a week or more—it’s worth being a little more strategic.
For longer trips, ensure:
Your HVAC system is in good working order (get a pre-vacation checkup)
Your air filters are clean
The thermostat is programmed or adjusted accordingly
There are no open vents or blocked registers
This level of preparation ensures your system runs efficiently without unnecessary wear while you’re away.
Additional Considerations for Vacationers
Security & Smart Home Integration
If you’re already using smart devices for lights, locks, and security, integrating your thermostat gives you full control over your home environment. You can monitor interior temperatures and respond quickly to any unusual changes, like power outages or HVAC failures.
Backup Power Options
Power outages during Georgia storms can happen while you’re out of town. If your AC stops working due to a loss of electricity, you could come home to high humidity and heat damage. Investing in a whole-home surge protector or backup power solution can add an extra layer of security.
Have a Trusted Contact Check In
Ask a neighbor, friend, or family member to stop by your home while you’re away. A quick check-in can catch any issues early, like an AC malfunction, water leak, or signs of pest activity.
Why This Matters for Newnan Homeowners
Newnan’s humid climate creates unique challenges for maintaining a home when you’re not there. Excess moisture in the air doesn’t just make things uncomfortable—it can cause long-term damage to walls, floors, furniture, and even your home’s foundation.
According to the U.S. Department of Energy, proper thermostat management while on vacation can reduce energy bills by 5%–15%, depending on the duration of your absence and the indoor/outdoor temperature differential. That’s a win-win for your budget and your peace of mind.
