The end of summer in Chester, SC often brings long, hot afternoons and heavy humidity. By this point in the season, your air conditioner has already worked hard for months—and it may start showing signs of wear and tear. Ignoring these small problems can lead to bigger repairs, higher bills, or even a breakdown when you still need cool air the most. Here are some of the most common late-summer AC problems you shouldn’t overlook. 1. Weak or Inconsistent Airflow If some rooms in your home feel cooler than others or your vents are barely blowing air, your AC could have clogged filters, leaky ducts, or a failing blower motor. Why it matters: Poor airflow forces your system to work harder, driving up energy costs and causing extra strain on components. 2. Strange Noises Banging, grinding, or squealing sounds coming from your unit aren’t normal. These noises can signal worn parts, loose components, or motor problems. Why it matters: Ignoring unusual sounds can turn a simple repair into a major breakdown. 3. Rising Energy Bills Late summer can push your system to its limit. If your energy bills are much higher than usual, your AC may be running inefficiently due to dirty coils, old parts, or low refrigerant. Why it matters: An inefficient system not only costs more to run but may also be close to failing. 4. Short Cycling Does your AC switch on and off frequently without cooling your home properly? This “short cycling” could be caused by thermostat issues, low refrigerant, or an oversized system. Why it matters: Short cycling wastes energy and puts extra wear on your system. 5. Musty or Unpleasant Odors High humidity in Chester can cause mold or mildew to build up inside your system. If you notice a musty smell when your AC runs, it’s a sign of excess moisture. Why it matters: Poor indoor air quality can impact your family’s health and comfort. Don’t Wait Until It’s Too Late Late-summer AC problems may seem minor, but they often get worse if ignored.

When the summer heat is beating down on Chester, SC, the last thing you want is for your air conditioner to give out. But if your system is old or struggling to keep up, it may be trying to tell you something - and ignoring the signs could lead to a complete breakdown at the worst possible time. At Cudd Heating & Air Conditioning Inc., we've seen it all. Here are some common warning signs that your AC might be on its last leg - and what to do about it. It's Blowing Warm Air If your system is running but only putting out warm or room-temperature air, that's a major red flag. It could be a refrigerant leak, compressor failure, or something more serious. Either way, warm air means your AC isn't doing its job - and that's a problem in a South Carolina summer. Weak or Inconsistent Airflow Are some rooms freezing while others feel like an oven? Weak or uneven airflow could point to issues with the ductwork, fan motor, or even the unit's internal components. In older systems, it often signals that wear and tear has taken its toll. Strange Noises or Smells Banging, rattling, grinding, or screeching sounds aren't normal. Neither are musty or burning smells. Unusual noises could indicate a loose part, while odd odors could mean mold in your system or electrical issues - both of which need prompt attention. Frequent Repairs If you feel like you're calling your HVAC tech more often than your family, it might be time to rethink your system. Older units tend to break down more frequently, and repair costs can add up fast. At some point, replacing the unit becomes the smarter long-term investment. Skyrocketing Energy Bills An aging or failing AC system works harder to produce the same cooling output - meaning your energy bills rise even if your usage hasn't. If your bills are climbing without explanation, your system's efficiency may be plummeting. It's Over 10-15 Years Old Most air conditioning systems last between 10 to 15 years with proper maintenance. If yours is in that age range and showing any of the signs above, it's likely nearing the end of its lifespan. Newer systems are also far more efficient and could save you money in the long run. What to Do Next If you're noticing one or more of these signs, it's time to have your system evaluated by a trusted local HVAC professional. At Cudd Heating & Air Conditioning Inc., we offer honest assessments and can help you decide whether a repair or full replacement makes the most sense. Don't let your AC quit in the middle of a Chester, SC heatwave. Give us a call today for a consultation or to schedule a system inspection - we're here to keep you cool when it matters most.

When the South Carolina summer hits full swing, few things are more frustrating than an air conditioner that sounds like it’s working—but doesn’t feel like it. If your AC is running but not cooling your home, you’re not alone. Here at Cudd Heating & Air Conditioning in Chester, SC, we frequently hear from homeowners dealing with this exact issue, especially during the peak heat and humidity of July and August. Let’s break down the most common reasons your AC may be running but not cooling, and what you can do about it. 1. Clogged or Dirty Air Filter A clogged air filter is one of the most overlooked causes of poor cooling performance. When your filter is dirty, it restricts airflow, making it harder for your AC to push cool air through your home. What to do: Check your air filter monthly during summer and replace it if it’s dirty. At Cudd Heating & Air, we recommend changing it at least every 60-90 days—or more often if you have pets or allergies. 2. Low Refrigerant Levels Your AC needs refrigerant to absorb heat from inside your home and release it outside. If your system has a leak or wasn’t properly charged, it will still run, but the air coming out will be warm or lukewarm. What to do: This isn’t a DIY fix. Call a certified HVAC technician from Cudd Heating & Air Conditioning to inspect your system for leaks, repair them, and recharge your refrigerant to factory specifications. 3. Frozen Evaporator Coil If your system is low on refrigerant, or if airflow is restricted (due to a dirty filter or blocked vents), your evaporator coil can freeze. That ice build-up prevents the coil from absorbing heat, which means your AC can’t cool your home effectively. What to do: Turn off your AC for a few hours to let the coil thaw. Then check your air filter and vents. If the problem persists, give us a call—we’ll diagnose and fix the underlying cause. 4. Thermostat Problems Your thermostat tells your AC what to do. If it’s miscalibrated, placed in a poor location, or malfunctioning, your AC might run at the wrong times or fail to cool properly. What to do: Make sure your thermostat is set to “cool” and that the temperature setting is lower than your current room temperature. Still having issues? We offer smart thermostat installations and repairs throughout Chester, SC. 5. Dirty or Blocked Condenser Unit Your outdoor condenser unit plays a critical role in cooling. If it’s blocked by leaves, grass, or debris—or covered in grime—it can’t release heat efficiently. That makes your whole system work harder with worse results. What to do: Carefully clean around the unit, and gently hose off the fins if needed (with the power turned off). For a deep clean or inspection, our Cudd Heating & Air techs can help. 6. Aging or Inefficient System Older AC units—especially those over 10-15 years old—often struggle to keep up with modern demands, especially during Chester’s muggy summers. They might run nonstop, yet never actually cool your home. Check out our air conditioner product page today to learn more about how we can keep your Chester, SC home cool and comfortable all summer long. What to do: If your system is outdated, inefficient, or constantly breaking down, it may be time for a professional AC replacement.

Summers in Chester, SC can be long, humid, and brutally hot—meaning your HVAC system has to work overtime to keep your home comfortable. At Cudd Heating & Air Conditioning, we believe the best way to avoid costly breakdowns and stay cool all summer long is to get your system ready before the real heat kicks in. Here are our top tips for preparing your HVAC system for a hot South Carolina summer: 1. Schedule a Professional Tune-Up The most important step is having your HVAC system professionally inspected and serviced. Our technicians will check refrigerant levels, clean coils, inspect electrical components, test airflow, and make sure everything is running efficiently. A preseason tune-up can catch small issues before they become expensive problems—and help your system run smoother when you need it most. 2. Replace or Clean Your Air Filter A dirty filter restricts airflow, causes your system to work harder, and can even lead to frozen coils or reduced cooling capacity. We recommend checking your filter every 30-60 days and replacing it as needed—especially during peak usage months. 3. Clean Around the Outdoor Unit Your outdoor condenser unit needs space and airflow to work efficiently. Clear away grass, leaves, dirt, and debris from around the unit. Keep at least two feet of open space on all sides, and trim back any shrubs or branches that may interfere. 4. Seal Air Leaks in Your Home Cool air can easily escape through poorly sealed windows, doors, and ductwork—wasting energy and putting strain on your HVAC system. Sealing these leaks helps your system cool your home more effectively and keeps your energy bills down. 5. Upgrade Your Thermostat Settings If you haven’t already, consider installing a programmable or smart thermostat. Setting higher temperatures while you’re away and cooling your home before you return can reduce energy usage without sacrificing comfort. 6. Consider an AC Replacement if Your Unit is Aging Is your system more than 10-15 years old? It might be time to start thinking about an upgrade. Newer HVAC systems are more energy-efficient and reliable—saving you money in the long run and giving you peace of mind when the summer heat rolls in.

As spring settles in across Chester, SC, many homeowners are taking the opportunity to get their HVAC systems ready for the warmer months ahead. While routine maintenance can keep your system running smoothly, there comes a point when repairs are no longer enough—and it might be time to consider a full replacement. At Cudd Heating & Air Conditioning, we want to help you recognize the signs that your air conditioner may be on its last leg and understand when investing in a new unit is the right move. How Old Is Your AC Unit? One of the first things to consider is the age of your current system. Most air conditioners are built to last between 10 to 15 years, depending on usage and how well they’ve been maintained. If your system is in that age range or older, it’s time to start thinking about a replacement—especially if you’ve noticed declining performance or rising energy bills. Frequent Breakdowns and Repairs Are you calling for AC repairs more often than you used to? While occasional fixes are normal, constant breakdowns are a red flag. The cost of repeated repairs can quickly add up, often making a new system the more economical and stress-free choice. A replacement might cost more upfront, but it can save you money over time by reducing repair costs and improving efficiency. Rising Energy Bills Spring and summer energy bills naturally increase with air conditioner use, but if you’ve noticed a steady climb without a change in usage habits, your system could be the culprit. Older or malfunctioning units often work harder than they should to maintain the desired temperature, using more energy and driving up your utility bills. A high-efficiency replacement unit can significantly lower your monthly costs. Uneven Cooling or Humidity Issues Are certain rooms in your home hotter or more humid than others? Uneven cooling and high humidity levels are common signs that your AC system is struggling. A well-functioning air conditioner should maintain even temperatures and help control humidity throughout your home. If yours isn’t doing the job anymore, it could be time to upgrade. Outdated Technology and Refrigerant If your air conditioner still uses R-22 refrigerant (also known as Freon), it’s definitely time to consider a replacement. R-22 has been phased out due to environmental concerns, making it increasingly expensive and difficult to find. Newer systems use environmentally friendly refrigerants and feature updated technology for improved performance, quieter operation, and better energy efficiency. Why Spring Is the Ideal Time to Replace Your AC Spring is one of the best times of the year to replace your air conditioner in Chester. The weather is still mild, giving you time to make the upgrade before the summer heat sets in. Scheduling installation in the spring also helps you avoid the rush of emergency service calls that come with peak summer temperatures, ensuring you’re ready to stay cool and comfortable all season long.
