Is Your AC Ready for the Lexington Summer? Here’s a Quick Checklist
May 29, 2025
Summer in Lexington, SC can be brutally hot and humid — and the last thing you want is for your air conditioner to fail just when you need it most. At Brian’s Heating & Cooling, we want to help you stay cool and comfortable all summer long. Here’s a quick checklist to make sure your AC is ready for the South Carolina heat.
✅ 1. Check and Replace Your Air Filter
One of the easiest — and most important — things you can do is replace your HVAC filter regularly. A dirty filter restricts airflow, reduces efficiency, and can put unnecessary strain on your system. We recommend checking your filter every month and replacing it at least every 60–90 days.
✅ 2. Inspect Your Thermostat
Make sure your thermostat is working properly and set to “cool.” If you’re still using an older manual thermostat, consider upgrading to a programmable or smart thermostat to save energy and improve comfort.
✅ 3. Clear Debris Around the Outdoor Unit
Your outdoor AC unit needs room to breathe. Clear away leaves, grass clippings, and any other debris within a two-foot radius. Trim back any bushes or shrubs that may be too close to the unit.
✅ 4. Check Air Vents and Registers
Walk through your home and make sure all vents are open and unobstructed. Blocked vents can lead to uneven cooling and increased energy bills.
✅ 5. Listen for Strange Noises
If your AC is making unusual sounds like banging, grinding, or squealing, that could be a sign something is wrong. Don’t wait — schedule a service call with our team before a small issue turns into a major repair.
✅ 6. Test the System Before Peak Heat
Turn your system on before the hottest days arrive to make sure it’s cooling properly. If you notice weak airflow, warm air, or the system isn’t turning on at all, give us a call right away.
✅ 7. Schedule a Professional AC Tune-Up
An annual maintenance check from Brian’s Heating & Cooling can extend the life of your system, improve efficiency, and catch small problems before they become big headaches. Our AC tune-ups include a full inspection, refrigerant check, coil cleaning, and more.
Don’t Wait Until It’s Too Late — Call Brian’s Heating & Cooling Today!

Fall is finally starting to feel like fall here in Lexington, SC! The mornings are getting cooler, the leaves are changing colors, and homeowners are spending more time outside enjoying the break from South Carolina's summer heat. But while you're raking leaves, cleaning gutters, and getting your yard ready for the cooler months, there's one important area you might be overlooking: your outdoor HVAC unit. Falling leaves, pine needles, and other yard debris can cause problems for your heating and cooling system if they're allowed to build up. A little attention now can help keep your equipment running smoothly as we head toward winter. Why Fall Leaves Can Be a Problem for Your HVAC System Your outdoor HVAC unit needs proper airflow to operate efficiently. Throughout the fall, leaves, grass clippings, pine needles, and other debris can collect around the unit and restrict that airflow. This is especially important for Lexington homeowners with heat pumps, since these systems rely on the outdoor unit to provide heating during the cooler months. When debris builds up around your equipment, it can lead to: Restricted airflow around the outdoor unit Reduced heating and cooling efficiency Additional strain on system components Increased wear and tear over time Potential heating or cooling problems Even if your system seems to be working normally, keeping the area around your outdoor unit clean is an easy way to help protect your investment. 1. Keep Leaves and Debris Away From Your Outdoor Unit As the leaves start falling, make it a habit to check around your outdoor HVAC equipment. Remove any leaves, pine needles, or branches that have collected around the base of the unit. It's also a good idea to keep nearby bushes and landscaping trimmed back to allow adequate airflow. Helpful tip: Try to maintain at least two feet of clearance around your outdoor unit or follow the manufacturer's specific recommendations. And while you're cleaning up the yard, avoid blowing leaves or grass clippings directly toward your HVAC equipment. They can become trapped around the unit and create airflow problems. 2. Don't Forget About Your Heat Pump Many homes throughout Lexington and the surrounding Midlands rely on heat pumps for both heating and cooling. Unlike a traditional furnace, a heat pump uses the outdoor unit even when it's heating your home. That means keeping the unit clear of leaves and debris is just as important in November and December as it is during the summer. If your outdoor unit is surrounded by fallen leaves or overgrown landscaping, your heat pump may have a harder time operating efficiently when temperatures drop. A quick visual inspection every week or two during peak leaf season can help you catch buildup before it becomes a bigger issue. 3. Be Careful When Cleaning Around Your Equipment While clearing leaves from around your HVAC system is generally a simple task, it's important to do it safely. Avoid sticking tools, rakes, or other objects inside the unit. You should also never attempt to remove panels or clean internal components yourself. If you notice a significant amount of debris trapped inside the equipment, it's best to have an HVAC professional take a look. Regular maintenance can help address buildup in areas that aren't easily accessible to homeowners. 4. Pay Attention as Temperatures Start Dropping Late October and November in Lexington can bring some beautiful weather, but those comfortable afternoons won't last forever. As cooler evenings become more common, your heating system will start getting more use. If you notice your system struggling to maintain a comfortable temperature, making unusual noises, or running differently than expected, don't ignore it. While leaves and debris aren't always the cause, restricted airflow is one of several issues that can affect HVAC performance. Addressing potential problems now can help you avoid an inconvenient breakdown when the colder weather arrives. A Little Fall Maintenance Goes a Long Way Fall is a great time to take care of the small things around your home before winter arrives. Just like cleaning your gutters or checking your weatherstripping, keeping your outdoor HVAC unit free of debris is a simple step that can make a difference. And if it's been a while since your last professional HVAC maintenance appointment, now is a good time to schedule one. At Brian's Heating & Cooling, we help homeowners throughout Lexington, SC, and the surrounding Midlands keep their heating and cooling systems operating safely and efficiently throughout the year. Whether you need seasonal maintenance, a heating system inspection, or help with an unexpected HVAC problem, our team is here to help. Don't wait until the first cold snap to find out your heating system needs attention! Call Brian's Heating & Cooling at 803-796-1788 to schedule your fall HVAC service and keep your home comfortable as South Carolina heads into winter.
September in Lexington, SC, can be a confusing time for your HVAC system. Summer may technically be winding down, but South Carolina weather doesn’t always get the memo. You may wake up to a cool morning, turn the air conditioner on by mid-afternoon, and then find yourself reaching for a blanket again that evening. These temperature swings are common during the transition from summer to fall, but constantly changing between heating and cooling can leave homeowners wondering how they should be using their HVAC system. Here are a few ways to stay comfortable as Lexington moves from summer heat into cooler fall weather. Is It Okay to Switch Between AC and Heat? Yes. Modern HVAC systems are designed to provide both heating and cooling as needed, so switching between the two during unpredictable fall weather isn’t necessarily a problem. However, it’s a good idea to give your system a few minutes after turning off one mode before switching to the other. Rapidly changing the thermostat back and forth can put unnecessary stress on the system. If your home is comfortable without heating or cooling, you can also turn the system off and take advantage of the milder weather. Don't Overreact to Cool Mornings One of the biggest challenges during early fall in Lexington is the difference between morning and afternoon temperatures. If you wake up to a chilly house, you may be tempted to immediately turn up the heat. But if warmer temperatures are expected later in the day, your home may naturally warm up without much help from your heating system. Instead of making big thermostat adjustments, try making smaller changes and allowing your home some time to respond. Take Advantage of Cooler Weather Early fall is one of the few times of year in South Carolina when your HVAC system may get a break. On comfortable days, opening windows can bring fresh air into your home without relying on your AC. Just remember that outdoor humidity and allergens can still be an issue, so keeping the windows closed may be a better option on particularly humid or high-pollen days. Ceiling fans can also help keep air circulating when it's not quite warm enough to justify turning on the air conditioner. Pay Attention the First Time You Turn on the Heat Even if daytime temperatures are still warm, cooler nights are coming. When you turn on your heating system for the first time this season, pay attention to how it performs. You may notice a slight dusty or burning smell during the first heating cycle as dust that settled during the summer burns off. This should typically disappear fairly quickly. However, persistent burning or electrical odors, unusual noises, weak airflow, or a system that isn't producing warm air are all reasons to have your HVAC system checked by a professional. It's much better to discover a heating problem during a mild September evening than during the first genuinely cold night of the season. Check Your Thermostat Settings Your thermostat can make the transition between seasons much easier. If you have a programmable or smart thermostat, review your schedule and temperature settings now. The settings that worked during July and August may no longer make sense as the days become shorter and outdoor temperatures begin to change. Some thermostats also have an "auto" mode that can automatically switch between heating and cooling based on the temperatures you've selected. If you're unsure how to use this feature correctly, an HVAC professional can help you determine the best settings for your home and equipment. Don't Ignore Comfort Problems During Mild Weather Because September weather can be relatively comfortable, it can be easy to overlook HVAC issues. Maybe one room isn't cooling as well as it did earlier in the summer. Perhaps you've noticed an unusual noise, weaker airflow, or your system seems to be running longer than usual. Those small issues are worth addressing before your system transitions into regular heating use. Mild weather gives you an opportunity to take care of problems before you truly depend on your heat. Get Ready for Fall in Lexington, SC Fall in Lexington doesn't always arrive all at once.

Our experienced team serves homeowners throughout Lexington, SC, and the surrounding Midlands with reliable heating and cooling service, maintenance, and repairs.

August in Lexington, SC, can put your air conditioner to the test. After running through months of heat and humidity, your AC has already done a lot of work—and there are still plenty of warm days ahead. At this point in the summer, you may start noticing little changes around your home. Maybe certain rooms don't feel as comfortable as they used to, your AC seems to run more often, or you're adjusting the thermostat more than usual. Not every change means there's a major problem but knowing what to watch for can help you catch an issue before you're left without air conditioning on a hot South Carolina day. 1. Your Home Doesn't Feel as Cool as It Used To You know how your home normally feels. If you're suddenly uncomfortable even though the thermostat is set to your usual temperature, your AC may not be cooling as effectively as it should. Pay attention if you're constantly lowering the thermostat just to stay comfortable. Your system may simply need some attention rather than a lower temperature setting. 2. Your AC Seems to Be Running All the Time Air conditioners naturally run longer when it's especially hot outside. However, if it seems like your system rarely gets a break—even during milder parts of the day—it may be worth having it checked. An AC that's working harder than necessary can also use more energy, which isn't something anyone wants to see on a late-summer electric bill. 3. Some Rooms Are Comfortable While Others Aren't Do you have one room that always feels warmer than the rest of the house? Maybe the living room feels great, but a bedroom never seems to cool down. Uneven temperatures can happen for several reasons. If it's a new problem or has become more noticeable this summer, an HVAC professional can help determine what's going on. 4. You're Hearing New or Unusual Sounds You don't have to know anything about HVAC equipment to recognize when something sounds different. If your air conditioner suddenly starts rattling, buzzing, squealing, or making another noise you haven't heard before, don't ignore it. Unusual sounds are often your system's way of letting you know something needs attention. 5. Something Just Doesn't Seem Right Sometimes there isn't one obvious warning sign. Your home may take longer to cool down, the air coming from the vents may not feel quite as cool, or your system may simply seem different than it did earlier in the summer. Trust what you're noticing. You live with your AC every day, so you're often the first person who will recognize when something has changed. There's Still Plenty of Summer Left in Lexington By August, it's easy to start thinking about fall—but South Carolina weather doesn't always cooperate. Your air conditioner may still have weeks of warm weather ahead of it. If your AC isn't keeping your home as comfortable as you'd like, you don't have to wait until it stops working completely to call for help. Taking care of a small issue now may help you avoid a much more inconvenient problem later. Brian's Heating & Cooling is here to help homeowners throughout Lexington, SC, stay comfortable through the rest of summer and beyond. Not sure if what you're noticing is normal? Give Brian's Heating & Cooling a call. Our team can take a look at your system, answer your questions, and help make sure your home stays comfortable.
