Why Your Heating System Might Be Cycling On and Off More Often in Winter
Rachel Eppley • January 14, 2026
Winter in the Lowcountry doesn’t usually bring long stretches of extreme cold — but we do experience frequent temperature swings. A chilly morning in the 30s can turn into a sunny afternoon in the 60s. While that’s great for outdoor plans, it can sometimes confuse your heating system. If you’ve noticed your heater turning on and off more frequently than usual, you’re not alone. This is called short cycling, and winter’s fluctuating temperatures are often the reason.
What Is Short Cycling?
Short cycling happens when your heating system starts up, runs for only a brief period, shuts off, and then starts again soon after. Instead of steady, efficient operation, the system is constantly restarting. Occasional cycling is normal — but repeated, rapid cycling can reduce efficiency, increase wear on components, and lead to higher energy bills over time.
Why It Happens More in Our Winter Climate
In areas like Charleston and the surrounding Lowcountry, outdoor temperatures can change quickly throughout the day. When the weather warms up suddenly:
- Your thermostat reaches the set temperature faster
- The system shuts off sooner than expected
- Then cooler evening temperatures cause it to start again
This constant adjustment can make your system work harder than necessary.
Other Common Causes
Temperature swings are one factor, but short cycling can also be caused by:
- A thermostat located near windows or exterior doors
- A system that’s larger than your home needs
- Dirty system components that restrict normal operation
- Aging equipment struggling to regulate output
How to Reduce Unnecessary Cycling
A few simple habits can help your system run more smoothly:
- Set a consistent temperature. Avoid large manual temperature changes throughout the day. Gradual adjustments keep your system from overreacting.
- Use a programmable thermostat. Let scheduled temperature changes happen automatically instead of constant manual tweaks.
- Check that vents are open. Proper airflow helps your system maintain steady operation.
- Schedule a winter system check. A quick professional inspection can confirm your system is sized correctly, calibrated properly, and operating efficiently.

When most people think of winter HVAC concerns, they picture freezing temperatures, rising heating bills, and staying warm indoors. But here in Charleston, winter brings a different challenge that homeowners often overlook: indoor humidity control. Even during the cooler months, Charleston’s coastal climate can keep humidity levels higher than expected—and if your home isn’t properly balanced, it can lead to discomfort, poor air quality, and even damage to your home. Why Humidity Is Still a Winter Issue in the Lowcountry Unlike colder regions where winter air is extremely dry, Charleston winters are relatively mild and moist. When your heating system runs, it can sometimes trap excess moisture inside your home instead of removing it. This can cause: A clammy or uncomfortable indoor feeling Condensation on windows Musty odors Increased risk of mold and mildew Aggravated allergies or respiratory issues If your home feels damp even when the heat is on, humidity may be the culprit. The Role Your Heating System Plays Many homes in the Charleston area rely on heat pumps, which are well-suited for our climate—but they still need to be properly maintained and correctly sized to manage both temperature and moisture. An inefficient or aging system may: Short-cycle and fail to remove moisture Run longer than necessary, increasing humidity Circulate allergens and airborne particles Routine winter maintenance ensures your system is operating efficiently and supporting healthier indoor air. Simple Steps to Improve Winter Comfort To keep your home comfortable and healthy this winter, consider the following: Schedule a seasonal HVAC tune-up to ensure your system is running efficiently Check indoor humidity levels (ideal range is typically 30–50%) Seal air leaks around windows and doors to prevent moisture intrusion Upgrade your air filtration to improve indoor air quality Ask about whole-home dehumidification options if humidity is a recurring issue Winter Is the Perfect Time for Preventive Care Because Charleston winters are milder, now is an ideal time to address HVAC concerns before the busy spring and summer seasons arrive. Preventive maintenance not only improves comfort now but can also extend the life of your system and reduce unexpected repairs later.

Fall has arrived in Charleston — the mornings are cooler, the air feels a little crisper, and your heating system is about to move from “just in case” to “you’ll need it.” Even though deep winter freezes may be rare here, that doesn’t mean your HVAC system should skip a tune-up. A few smart checks now will help you stay comfortable, efficient, and avoid surprises later. 1. Transition Smart: The Heat Pump Mode Swap Many homes in the Lowcountry rely on a heat pump for both cooling and heating. During the fall, it’s an ideal time to make sure the system transitions cleanly. Switch your thermostat to “heat” and let the system run for a short period, watching for odd noises or poor performance. Clear debris away from your outdoor unit — leaves or pine straw can block airflow and reduce efficiency now and when it really matters. Confirm the outdoor unit has at least 2 ft of clearance and that the fan is unobstructed. A smooth transition now keeps your system ready for days when you’ll need the heat — without waiting until it’s inconvenient. 2. Moisture, Humidity & Air Quality: A Fall Primer Charleston’s fall air can feel comfortable, but indoor comfort still depends on airflow and humidity. Check if your home feels cold while the thermostat is set at a comfortable temperature. It could be due to drafts, blocked returns, or the fan being on “On” instead of “Auto.” As cooler nights set in, keep an eye on indoor humidity. Too low (under ~40%) and your home may feel colder; too high (over ~50%) and you risk mold or allergens becoming an issue. Clean or replace filters now — during the switch from cooling to heating, a clogged filter magnifies load and can bring inefficiency. 3. Thermostat Strategy for the Seasonal Shift Right now, you could be heating in the morning, cooling during the day, and heating again at night. That roller-coaster can confuse older systems. Set your fan to “Auto” so that the blower only runs when the system actively heats — this saves energy and prevents unnecessary wear. If you have a smart or programmable thermostat, create a schedule: slightly lower set-point while you’re out, bump it when you’re home. Ensure the thermostat isn’t placed near a cold draft or hot sunlight — location still matters. 4. Seal the Gaps: Small Leaks (Big Impact) Even mild fall nights can expose insulation and air-leak issues. Inspect around doors and windows for drafts and add weather-stripping if needed. Verify attic access panels or crawl-space vents are properly sealed for the season. Walk into each room that always feels colder — it may signal leaky ducts or imbalanced airflow that’s easier to rectify now than during full-wind-chill winter.

As fall settles into the Lowcountry, mornings are cooler, evenings are crisp, and the air conditioning finally gets a well-earned break. But before you flip your system to “heat” and forget about it, it’s worth taking a few simple steps to make sure your heat pump is running at peak efficiency for the months ahead. Here in Charleston, we rely on our heat pumps year-round — for both cooling and heating — and that means a little seasonal attention goes a long way toward lower bills and better comfort. Switch Modes Smoothly Your heat pump works differently than a traditional furnace. When it transitions from cooling to heating, it’s normal to hear a few new sounds or feel slightly cooler air from the vents at first. However, if your system struggles to reach temperature or runs constantly, that’s a sign it could use a tune-up. Before the first truly chilly week arrives, switch your thermostat to “heat” and let the system run for 10–15 minutes to make sure everything transitions smoothly. Adjust Your Thermostat Settings for the Season Fall is a perfect time to rethink thermostat habits: Set a comfortable base temperature — around 68°F when you’re home and awake. Use a programmable or smart thermostat to automatically adjust when you’re asleep or away. Avoid setting the temperature too high too fast; gradual changes prevent your system from switching into less-efficient “auxiliary heat” mode. These small adjustments can reduce energy use significantly without sacrificing comfort. Clear Around Your Outdoor Unit Falling leaves, pine needles, and yard debris can collect around your outdoor unit, restricting airflow. Take a few minutes to: Trim back vegetation within two feet of the unit Gently rinse away dirt or debris with a garden hose Check for signs of damage or corrosion after hurricane season Good airflow helps your system exchange heat efficiently — a key factor in keeping energy costs low. Check Insulation and Weatherstripping Even in our mild Charleston winters, poor insulation can make your system work harder than it should. Inspect: Weatherstripping around doors and windows Attic insulation, especially above living spaces Drafts near baseboards or crawlspaces A few quick fixes (like new door seals or outlet gaskets) can keep warm air inside — and your heat pump from cycling on and off too often. Schedule a Fall Maintenance Check Your heat pump works double duty all year long, so professional maintenance twice a year is best. A fall tune-up ensures: Heating coils and defrost cycles are working properly Refrigerant levels are balanced Electrical connections are tight Backup heat strips (if you have them) are tested before you need them A well-maintained system can save you up to 25% on energy costs — and avoid the stress of a cold-morning breakdown. Charleston’s fall and winter may not bring snow, but our heat pumps still earn their keep. A little preparation now can mean steady comfort and lower utility bills all season long.

At Terrace Heating & Air, we understand that Charleston's unique climate can impact your home's indoor air quality. Between high humidity, seasonal allergens, and occasional airborne pollutants, the air inside your home can be less clean than you think. Breathing cleaner air isn’t just about comfort—it’s about protecting your health and the well-being of your family. Here are some practical tips to help you improve indoor air quality and maintain a healthier home environment. 1. Invest in a Quality Air Purifier Air purifiers with HEPA filters are highly effective at capturing airborne particles such as dust, pollen, pet dander, and even some bacteria. For maximum benefit, place them in high-traffic areas or rooms where family members spend the most time. Consider models that also reduce odors and VOCs for a fresher home environment. 2. Maintain Your HVAC System Regularly Your HVAC system plays a critical role in circulating and filtering air throughout your home. Regular maintenance—including cleaning ducts, replacing filters, and inspecting for any issues—ensures your system is running efficiently and helps prevent contaminants from circulating. Scheduling annual inspections with professionals can save you headaches down the line and keep your indoor air clean. 3. Control Humidity Levels Charleston’s humid climate can encourage mold, mildew, and dust mites. Using dehumidifiers in damp areas like basements, bathrooms, or laundry rooms helps maintain optimal humidity levels and prevents the growth of these allergens. Proper humidity control also helps preserve wood floors, furniture, and other household materials. 4. Choose Low-VOC Products Volatile organic compounds (VOCs) from paints, adhesives, furniture, and cleaning products can negatively impact indoor air quality. When redecorating or renovating, choose low-VOC or VOC-free products to minimize harmful emissions in your home. 5. Ensure Proper Ventilation Good airflow is essential for removing indoor pollutants. Open windows whenever the weather allows and make sure exhaust fans in kitchens and bathrooms are functioning properly. Proper ventilation not only improves air quality but also helps regulate temperature and humidity. 6. Incorporate Indoor Plants Certain indoor plants, like spider plants, peace lilies, and snake plants, can naturally filter toxins from the air while adding beauty to your home. While they shouldn’t replace proper ventilation or filtration, they can complement your overall air quality strategy. By implementing these strategies, Charleston homeowners can breathe easier, reduce allergens, and create a more comfortable living space year-round.

When summer hits Charleston, your air conditioner works hard to keep your home cool and comfortable. But what if it’s working harder than it needs to—costing you extra money every month? An inefficient AC doesn’t just drain your wallet; it can also shorten the lifespan of your system and leave you sweating on the hottest days. At Terrace Heating & Air, we want to help you spot the warning signs before small issues turn into big expenses. Here are some clear indicators your AC might be costing you more than it should. 1. Your Energy Bills Keep Rising If your monthly energy bills are creeping up without a change in usage, your AC could be to blame. Dirty filters, worn-out parts, or poor airflow can force your system to run longer and use more electricity to achieve the same results. Pro Tip: Compare this year’s summer bills to last year’s. If there’s a big jump, it’s worth getting your system checked. 2. Uneven Cooling Throughout Your Home Are some rooms freezing while others feel like a sauna? This could be a sign of duct leaks, inadequate insulation, or an AC unit that’s struggling to keep up. Uneven cooling often means wasted energy and an overworked system. 3. The AC Runs Constantly While your AC will naturally run more during Charleston’s heat waves, it shouldn’t be running non-stop. Constant operation often points to an undersized unit, refrigerant leaks, or mechanical issues that make it harder for your system to reach your set temperature. 4. Weak Airflow If you notice reduced airflow from your vents, your system could be dealing with clogged filters, duct blockages, or a failing blower motor. Weak airflow forces your AC to work overtime, driving up costs. 5. Strange Noises or Smells Banging, grinding, or squealing noises signal possible mechanical problems, while musty or burning odors could indicate mold growth or electrical issues. Ignoring these warning signs can lead to costly breakdowns—and higher energy bills in the meantime. 6. Your AC is Over 10–15 Years Old Older systems naturally lose efficiency over time. Even with regular maintenance, an older AC may require more energy to cool your home compared to a newer, high-efficiency model. How to Lower Costs and Improve Efficiency Schedule Regular Maintenance: Annual tune-ups keep your system running at peak performance. Change Filters Monthly: Clean filters improve airflow and reduce strain on your AC. Seal Duct Leaks: Prevent cooled air from escaping before it reaches your rooms. Consider an Upgrade: Newer systems can dramatically cut energy usage and costs. Don’t Let Inefficiency Drain Your Wallet If your AC is showing any of these signs, it’s time to call the experts. Terrace Heating & Air proudly serves Charleston and the surrounding Lowcountry with professional maintenance, repairs, and energy-efficient upgrades. 📞 Call us today at 843-762-3639 or schedule your service online to make sure your AC is cooling efficiently—without costing you more than it should.
When summer hits hard in Charleston, your air conditioner becomes one of the most important systems in your home. But with the extreme heat, heavy humidity, and salt air, your AC system is working overtime—and that can lead to problems. At Terrace Heating & Air, we’ve helped hundreds of Lowcountry homeowners stay cool, and we’ve noticed some common issues that tend to pop up every summer. If your AC is struggling, here’s what might be going on—and how we can help. 1. Refrigerant Leaks Refrigerant is what cools the air inside your home, and when it leaks, your system can’t do its job properly. Charleston’s salty coastal air can cause corrosion in copper lines, making leaks more likely. Signs of a refrigerant issue: Warm air blowing from vents Longer run times Hissing or bubbling sounds Good news: Our techs can find and fix the leak, recharge your system, and help prevent future issues. 2. Frozen Evaporator Coils It might sound strange, but frozen coils are a common summer problem. Dirty air filters, restricted airflow, or low refrigerant can cause ice to build up, especially in Charleston’s high-humidity environment. What you’ll notice: Weak airflow AC running but not cooling Water pooling near the indoor unit Tip: Changing your air filter regularly and scheduling routine maintenance can help prevent this. 3. Clogged Drain Lines With our humidity levels, your AC pulls a lot of moisture out of the air—and that moisture drains through a condensate line. Over time, algae and gunk can build up and block the line, leading to water leaks and even system shutdowns. Watch for: Water around your unit Musty smells AC not turning on We can quickly clear the line and keep your system draining like it should. 4. Capacitor or Contactor Failure Your AC has electrical components that help it turn on and stay running. The extreme heat can cause these parts—especially capacitors and contactors—to overheat and fail. Signs something’s wrong: AC won’t start Clicking noises Unit turning on and off repeatedly Don’t try to fix electrical components yourself. Give us a call and we’ll get you back up and running safely. 5. Dirty or Blocked Condenser Units Your outdoor unit needs proper airflow to release heat from your home. When it gets clogged with dirt, grass clippings, or coastal debris, your system has to work harder—and may eventually shut down. Pro tip: Keep the area around your outdoor unit clear and schedule a summer cleaning to keep it efficient. Stay Cool with Fast, Local Service At Terrace Heating & Air, we’re proud to be Charleston’s go-to AC repair team. We know how brutal Lowcountry summers can be—and how important it is to have a system you can count on.

If your air conditioner is running but your home still feels hot and muggy, you’re not alone. Charleston’s high heat and coastal humidity can put a major strain on your cooling system—and one issue we see time and time again is the #1 reason your AC isn’t cooling properly: a dirty or clogged air filter. Why Your Air Filter Matters More Than You Think Your AC system relies on proper airflow to function efficiently. When your air filter gets clogged with dust, pollen, pet hair, or other debris, it blocks that airflow—making your system work harder while cooling less effectively. In Charleston, this problem is even more common during the summer months when: Pollen levels are high Pet shedding increases indoors Humidity causes filters to trap more moisture and debris AC systems are running almost nonstop A dirty filter doesn’t just reduce cooling—it can also cause your coils to freeze, reduce energy efficiency, and even shorten the life of your system. Signs Your Filter Is the Problem Not sure if your filter is the culprit? Here are a few red flags to watch for: Warm air blowing from vents Weak airflow in certain rooms Higher-than-usual energy bills AC running constantly but not reaching set temperature Increased indoor humidity How Often Should You Change It? In Charleston’s climate, we recommend checking your filter once a month during the peak cooling season (May through September). You may need to change it more frequently if: You have pets You live near construction or marsh areas You suffer from allergies Your AC runs constantly Don’t Let a Simple Fix Turn Into a Costly Repair At Terrace Heating & Air, we see it all the time—a customer calls us for what seems like a serious AC problem, and it turns out the solution is as easy as replacing the air filter. That’s why routine maintenance is key to keeping your system running efficiently all summer long. Need Help With Your Cooling System in Charleston? If your AC still isn’t cooling after changing the filter, there could be a more complex issue—like low refrigerant, dirty coils, or a failing compressor. The experts at Terrace Heating & Air are here to help with fast, friendly service across the Charleston area. Contact us today to schedule a service visit or sign up for a preventive maintenance plan—and keep your cool all summer long.

Top Spring Maintenance Tips from Our Charleston HVAC Experts Here are a few simple but important steps to get your AC system in top shape: 1. Replace or Clean Air Filters Dirty filters reduce airflow and make your system work harder. We recommend changing your air filter at least every 1-3 months—especially in the spring when pollen levels are high in Charleston. 2. Check and Clean Your Outdoor Unit Leaves, dirt, and debris can block airflow to your outdoor condenser unit. Make sure the area around the unit is clear and gently hose off any buildup to improve efficiency. 3. Inspect Thermostat Settings Now’s a great time to test your thermostat and program it for energy savings. Consider upgrading to a smart thermostat for better control and efficiency during Charleston’s fluctuating spring and summer temps. 4.

Charleston summers are no joke. Between the soaring temperatures and thick coastal humidity, your air conditioner in Charleston works hard to keep your home cool and comfortable. But if your system is struggling now, it may not make it through another Lowcountry summer without major repairs—or even total failure. At Terrace Heating & Air, we want to help you stay ahead of the heat. Here are some warning signs your AC unit might be on its last legs. 1. Weak or Warm Airflow If your vents are blowing warm air or the airflow feels weak no matter how low you set your thermostat, it’s a clear sign that something’s wrong. This could mean your air conditioning system is dealing with a failing compressor, low refrigerant, or just can’t keep up with Charleston’s extreme summer temperatures. 2. Strange Noises Hearing grinding, rattling, or banging? Those sounds aren’t normal. Your HVAC system should operate relatively quietly. Unusual noises can point to worn-out parts, loose components, or serious mechanical issues—often signs your air conditioner needs replacement. 3. High Energy Bills Has your electric bill in Charleston been creeping up lately? Older or inefficient air conditioning units work harder to keep your home cool. If your system is running constantly but your home still isn’t comfortable, it might be time for an HVAC upgrade. 4. Frequent Repairs Needing one repair every few years is normal. Needing multiple AC repairs in Charleston in a single season? That’s a red flag. Constant issues not only cost you money but also suggest your system is nearing the end of its life. 5. Uneven Cooling If some rooms feel like a sauna while others are freezing, you might have uneven cooling. That could mean your system is too old or too small—or that your ductwork is struggling. Either way, it’s time to have your Charleston air conditioning system inspected. 6. Your AC Is 10+ Years Old Most air conditioners in South Carolina last around 10–15 years, but Charleston’s heat and humidity can shorten that lifespan. If your system is 10 years or older and not keeping up, it’s probably time to consider a new AC installation. Don’t Get Caught in the Heat The last thing you want is for your air conditioner to break down during a Charleston summer. If you’ve noticed any of these signs, Terrace Heating & Air is here to help. We’ll inspect your system, walk you through your options, and make sure your home stays cool and comfortable.

As we say goodbye to winter and welcome the warmer temperatures of spring, it’s the perfect time to prepare your HVAC system for the upcoming change in weather. In Charleston, we experience a unique blend of mild winters and hot, humid summers, making HVAC maintenance essential to ensure your home stays comfortable throughout the year. Here’s how you can get your HVAC system ready for Charleston’s spring weather. 1. Schedule a Professional Spring Maintenance Check Spring is the perfect time to schedule a professional maintenance appointment. HVAC systems that are well-maintained are more energy-efficient and last longer. A professional technician will inspect and clean the system, check refrigerant levels, and address any wear and tear that may have occurred during the winter months. By catching small issues early, you can avoid costly repairs down the road. 2. Change the Air Filter Air filters play a crucial role in maintaining air quality and system efficiency. Over time, filters become clogged with dust, dirt, and debris, making it harder for your system to circulate air effectively. Spring is a great time to change your air filter to ensure proper airflow and maintain a clean, healthy home environment. 3. Clean the Coils and Condenser Unit If you have an outdoor condenser unit, make sure it’s clear of debris, dirt, and leaves that may have accumulated over the winter. Clean the coils and check for any damage that could affect the system’s performance. Keeping the area around the unit clear will allow it to run more efficiently during the hot Charleston summer months. 4. Test the Thermostat As the weather warms up, you’ll rely more on your air conditioner. Test your thermostat to ensure it’s working properly. If your thermostat is outdated or malfunctioning, it could cause your HVAC system to work harder than necessary, leading to higher energy bills. Consider upgrading to a smart thermostat for improved control and energy savings. 5. Check for Air Leaks Springtime in Charleston can bring unpredictable weather, with sudden rainstorms or humidity spikes. Make sure your home is sealed properly by checking for drafts around doors, windows, and ducts. Sealing air leaks can prevent your HVAC system from overworking and help maintain a consistent indoor temperature. 6. Clear Drainage Lines As your HVAC system works harder to keep your home cool during the warmer months, condensation will build up. It’s important to check and clear your drainage lines to prevent clogs that could lead to water damage or system malfunctions. Clean and inspect the drainage lines regularly, especially after a heavy rainstorm. 7. Upgrade Your Insulation If your insulation isn’t up to par, your HVAC system may have to work harder to maintain the desired temperature. Spring is a great time to check your home’s insulation, particularly in attics, basements, and crawl spaces. Adequate insulation keeps cool air inside during the summer and helps regulate your home’s temperature more effectively. 8. Consider Upgrading Your System If your HVAC system is more than 10 years old, it may be time to think about an upgrade. Newer models are designed to be more energy-efficient, which can save you money in the long run. If you’re unsure about the condition of your current system, Terrace Heating & Air can help you assess its efficiency and provide recommendations.
