Late-Summer AC Problems Charleston Homeowners Shouldn’t Ignore

When your air conditioner won’t stop running, it’s more than just an annoyance—it can mean higher energy bills, extra wear and tear on your system, and uncomfortable indoor temps. Here in Charleston, where the summer heat and humidity are no joke, your AC may need to work hard—but if it’s running nonstop, something’s not quite right. At Carolina Climate Control, we get a lot of calls from Lowcountry homeowners about this issue. Here's what might be causing it—and what you can do to fix it. 1. It’s Just That Hot and Humid Let’s start with the obvious: Charleston summers are hot. With temps in the 90s and humidity through the roof, your AC has to work overtime to keep your home cool. If your system is properly sized and running efficiently, it may still run longer than usual on those sweltering days—but it shouldn’t run 24/7. What to do: If it’s just extreme weather, your AC might be doing its job. But if it’s running nonstop for days, or never reaches the set temperature, it’s worth having it checked. 2. Your Air Filter Is Dirty A clogged filter restricts airflow, which can make your AC struggle to cool your home. That means it runs longer—and uses more energy—to do the same amount of work. What to do: Check your filter. If it looks dirty or hasn’t been changed in over a month, swap it out. Carolina Climate Control recommends checking your filter at least once a month during the cooling season. 3. Thermostat Trouble If your thermostat is set incorrectly or isn’t working right, your AC may not know when to shut off. A malfunctioning thermostat could be sending the wrong signals. What to do: Make sure your thermostat is set to “auto” (not “on”), so the fan only runs when needed. If you suspect a problem, try replacing the batteries or upgrading to a smart thermostat—our team can help you choose one that works best for your home. 4. Leaky Ductwork If cool air is escaping through holes or gaps in your ductwork, your AC will keep running to compensate—even though your living spaces aren’t getting the cool air they should. What to do: Leaky ducts are surprisingly common in Charleston homes, especially older ones. A professional duct inspection and sealing service can help restore efficiency and comfort. 5. Your AC Is the Wrong Size Bigger isn't always better. An oversized unit can short cycle (turn on and off too often), while an undersized unit may run constantly and still not keep you cool. What to do: If your AC has always struggled or run nonstop, you might have a sizing issue. Carolina Climate Control can evaluate your home and recommend the right solution—whether it's a new system, a zoning upgrade, or efficiency improvements. 6. Time for a Tune-Up (or a Repair) Sometimes, your system just needs a little TLC. Dirty coils, low refrigerant, or worn-out parts can all force your AC to work harder than necessary. What to do: Schedule a maintenance visit. Our certified HVAC technicians will inspect your system, clean components, check refrigerant levels, and make sure everything is running smoothly. Preventative maintenance can save you from costly breakdowns—and lower your monthly bills. Stay Cool, Charleston Your AC shouldn’t have to run all day to keep you comfortable. If your system is acting up or running nonstop, don’t wait until it breaks down. Let the experts at Carolina Climate Control take a look and get your cooling system back on track. 👉 Schedule your service today or ask about our Moose Maintenance Plan to keep your air conditioning unit running efficiently all summer long.

Summers in Charleston can be brutal—with high humidity, blazing sun, and sticky air that doesn't let up. Your air conditioner has to work overtime just to keep your home comfortable. But what happens when your AC system starts to fall behind? At Carolina Climate Control, we know the signs of AC trouble better than anyone, especially in Lowcountry conditions. Here are the top 5 signs your air conditioner is struggling in Charleston’s humid heat—and what to do about it. 1. Your AC Is Running Constantly But You’re Still Uncomfortable If your system seems like it's on all the time but your home still feels warm and muggy, it's likely a sign that your AC is overworked. Charleston’s humidity makes it harder for AC systems to remove moisture from the air, especially if the unit is undersized or not maintained. What to do: Call us for an AC performance check. It could be as simple as a dirty coil or a refrigerant issue—or a sign that your system needs an upgrade. 2. You Notice Hot and Cold Spots Throughout the House Inconsistent temperatures from room to room can mean poor airflow, ductwork issues, or a failing blower motor. In high-humidity areas like Charleston, excess moisture can even impact airflow and cause uneven cooling. What to do: Ask about an airflow test or duct inspection. We’ll pinpoint the issue and restore balanced comfort throughout your home. 3. Your Energy Bills Are Climbing for No Clear Reason AC units under stress will run longer and harder—especially when battling Charleston’s coastal humidity. If your summer energy bills are noticeably higher than usual, your system could be losing efficiency. What to do: Schedule a preventative maintenance visit. We’ll check for worn parts, dirty filters, or failing components that drive up energy use. 4. There’s a Musty or Damp Smell Coming From Your Vents Humidity is the perfect breeding ground for mold and mildew inside your HVAC system. If your AC isn’t dehumidifying properly, you might notice a musty odor when it kicks on—a clear sign of excess moisture or microbial growth. What to do: Have us inspect your evaporator coil and drain lines. We may recommend a whole-home dehumidifier for better moisture control in Charleston's climate. 5. Your System Is Short Cycling (Turning On and Off Frequently) Short cycling—when your AC turns on and off rapidly without completing a full cooling cycle—is hard on your equipment and usually signals a problem. It could be due to thermostat issues, a dirty filter, or even a refrigerant imbalance. What to do: Book a system diagnostic right away. Short cycling can lead to bigger, more expensive breakdowns if left unresolved.

But excessive humidity can overwhelm a poorly maintained system, leading to: Reduced cooling efficiency Higher energy bills Musty odors or mold growth Increased wear and tear If your AC isn’t properly serviced, you may be in for some uncomfortable (and expensive) surprises this summer. Signs Your Air Conditioner May Not Be Ready Here are a few red flags that your AC might need attention before the real heat sets in: Weak airflow or uneven cooling Strange noises or foul smells Rising energy bills without increased usage AC runs constantly but doesn’t lower the temperature Excess humidity inside your home If you're experiencing any of these issues, it's time to schedule a professional HVAC inspection.

As the warm, humid days return to Charleston, SC, your air conditioner becomes one of the most important systems in your home. But what if it’s not working as well as it used to? If you're noticing higher energy bills, uneven cooling, or strange noises coming from your AC, you might be asking yourself: Should I repair or replace my old air conditioner this spring? At Carolina Climate Control, we help Lowcountry homeowners make smart, informed decisions about their cooling systems. Here’s how to know which option is right for you. When a Repair Makes Sense Sometimes, your AC just needs a little attention to get back to peak performance. Consider scheduling a repair if: The system is less than 10 years old and has been well-maintained. This is the first time you've had an issue in a while. The repair is minor, such as a faulty capacitor, dirty coils, or a clogged filter. Your energy bills haven't drastically increased and your home still cools evenly. Repairs are often a cost-effective way to extend the life of your system—especially when caught early with a routine spring tune-up. Signs It’s Time to Replace Your AC Unit While repairs can fix many problems, they may not be worth it in the long run if your system is outdated or constantly struggling to keep up. Here are key signs it may be time for a replacement: Your unit is 10–15 years old or older. You’re paying for frequent or costly repairs. Your home isn’t cooling consistently, even after maintenance. You hear loud or unusual noises coming from your unit. Your energy bills keep climbing, even though your usage hasn’t changed. Newer air conditioning systems are significantly more energy-efficient than older models, which means you could see immediate savings on your monthly energy bills. Benefits of Replacing Your AC in the Spring Spring is the ideal time to replace your air conditioning unit in Charleston. Here’s why: Avoid the summer rush – HVAC companies get booked quickly once the heat kicks in. Take advantage of early-season promotions and manufacturer rebates.

Enhanced Comfort & Automation Smart thermostats ensure your home is always at the perfect temperature when you need it. Features like geofencing can detect when you’re on your way home and adjust the temperature accordingly. Some models even integrate with voice assistants like Alexa or Google Assistant for hands-free control. 4. Compatibility with Charleston’s Climate Spring in Charleston brings fluctuating temperatures, making it challenging to maintain consistent indoor comfort. A smart thermostat can automatically adjust settings based on weather conditions, keeping your home cool during sudden warm days and comfortable during cooler nights. 5.

As the winter season approaches in Charleston, South Carolina, it’s time to ensure your HVAC system is ready to keep your home warm and comfortable. While winters here are generally mild, the occasional cold snap can put your heating system to the test. At Carolina Climate Control, we want to help you prepare your HVAC system for the season ahead with these essential tips. 1. Schedule a Professional Maintenance Check Before winter fully sets in, schedule a maintenance visit with our experienced technicians. Regular maintenance helps identify potential issues before they become costly repairs. During the checkup, we’ll inspect your system, clean components, and ensure everything is operating efficiently. 2. Replace or Clean Your Air Filters Clean air filters are vital for efficient HVAC performance. Dirty filters can restrict airflow, forcing your system to work harder and increasing energy costs. Replace or clean your filters monthly, especially during periods of heavy use. 3. Test Your Thermostat Ensure your thermostat is working properly and set to your desired temperature. If you’re still using a manual thermostat, consider upgrading to a programmable or smart thermostat for better temperature control and energy savings. 4. Inspect Your Ductwork Leaky or poorly insulated ductwork can lead to significant heat loss, making it harder for your HVAC system to maintain a consistent temperature. A professional inspection can identify and seal any leaks, ensuring your system operates efficiently. 5. Check Your Insulation Good insulation keeps warm air inside and cold air out. Inspect your home’s insulation, especially in the attic and around windows and doors. Adding weather stripping or caulking can make a big difference in maintaining indoor comfort. 6. Clear the Area Around Your HVAC System Make sure your outdoor unit is free of debris such as leaves, dirt, and branches. A clean unit operates more efficiently and is less likely to experience issues during the colder months. 7. Be Prepared for Emergencies Charleston winters can bring unexpected weather changes. Make sure you have a plan in place for power outages and other emergencies. Keep blankets, portable heaters, and emergency contact numbers on hand, including our 24/7 service line for urgent HVAC repairs. 8. Consider Upgrading Your System If your HVAC system is more than 10-15 years old, it might be time to consider an upgrade. Modern systems are more energy-efficient and reliable, ensuring your home stays comfortable while lowering your utility bills. To learn more about some of the energy-efficient products we carry and install, check out some of our product pages . Trust Carolina Climate Control to Keep You Comfortable This Winter Preparing your HVAC system for winter doesn’t have to be stressful.

As the cooler months approach, Charleston homeowners are beginning to think about how to keep their homes warm and cozy without breaking the bank on energy bills. With a variety of energy-efficient heating options available today, it’s easier than ever to find a system that balances comfort and cost savings. At Carolina Climate Control, we’re here to help you explore the best solutions for your home this winter. 1. Heat Pumps: A Year-Round Solution Heat pumps are one of the most efficient heating options for Charleston’s mild winters. These systems work by transferring heat from the outside air into your home, using less energy compared to traditional heating methods. Many modern heat pumps also double as air conditioners, making them an excellent year-round investment. If you’re considering a heat pump, look for models with a high Heating Seasonal Performance Factor (HSPF) for maximum efficiency. And if you already have a heat pump, regular maintenance ensures it operates at peak performance. 2. Ductless Mini-Split Systems For homes without ductwork or those looking to heat specific areas, ductless mini-split systems are a fantastic choice. These systems allow for zoned heating, meaning you can heat only the rooms you’re using, reducing energy waste. They’re also quiet, compact, and highly efficient, making them a popular option for Charleston homeowners. 3. High-Efficiency Furnaces If you prefer a traditional furnace, upgrading to a high-efficiency model can make a significant difference in energy savings. Modern furnaces with an Annual Fuel Utilization Efficiency (AFUE) rating of 90% or higher convert most of the fuel they consume into heat, minimizing waste. Pairing your furnace with a programmable or smart thermostat can further enhance efficiency by allowing you to set heating schedules and avoid heating your home when no one is there. 4. Radiant Floor Heating While not as common, radiant floor heating is a luxurious and efficient way to keep your home warm. This system uses electric heating coils or water-heated tubing beneath your floors to provide even, consistent heat throughout a room. It’s especially appealing for homes with tile or hardwood flooring. Tips for Maximizing Efficiency Regardless of the heating system you choose, there are simple steps you can take to make your home more energy-efficient this winter: Seal Drafts: Check for air leaks around windows and doors and seal them with weatherstripping or caulk. Insulate: Proper insulation in your attic and walls helps retain heat. Maintain Your System: Schedule regular maintenance with Carolina Climate Control to ensure your heating system runs efficiently all season long. Find the Right Solution with Carolina Climate Control Choosing the best heating option for your Charleston home depends on your budget, home size, and personal preferences. At Carolina Climate Control, we specialize in helping homeowners find energy-efficient solutions that keep their homes comfortable and their energy bills manageable.
