When you live in Winston-Salem, you know summer doesn’t hold back. With sweltering days and sticky nights, your air conditioner is your home’s MVP. So when your AC suddenly starts blowing warm air instead of cool relief, it's more than just inconvenient—it can make your home downright unbearable. If you're experiencing this all-too-common issue in the Triad area, don’t sweat it (literally). Here’s a breakdown of why your AC might be blowing warm air—and what you can do to fix it fast. 1. Your Thermostat Settings Might Be to Blame Sometimes the solution is simpler than you think. A thermostat accidentally set to “heat” or “fan” instead of “cool” can cause your AC to blow warm air. This can happen after a power outage or during seasonal switchovers. Check out our thermostat product page today to learn more about some of the smart thermostats we carry and install here at Gwyn Services. What to do: Double-check your thermostat settings. Make sure it’s set to “cool” and that the temperature is set lower than the current room temp. If it's a smart thermostat, consider resetting it or checking the app settings. 2. Your Air Filter Is Clogged In Salem and surrounding areas like Kernersville and Clemmons, the pollen and dust levels can climb high, especially in spring and summer. A dirty air filter restricts airflow, which can cause your system to overheat—and start blowing warm air instead. What to do: Change your filter! Experts recommend replacing it every 30–90 days, especially during peak cooling season in Winston-Salem. Not only will this restore airflow, but it’ll also improve your indoor air quality. 3. Your Outdoor Unit Lost Power or Is Dirty Your AC’s indoor unit depends on the outdoor condenser to release heat. If the outdoor unit loses power or gets clogged with leaves, grass, or dirt (which is common in our tree-lined NC neighborhoods), your system won’t cool your air properly. What to do: Step outside and inspect your outdoor unit. Clear away any visible debris. Check if the fan is spinning—if not, a breaker might have tripped. Never attempt electrical repairs yourself. If in doubt, call a licensed HVAC technician here in Salem, NC. 4. Low Refrigerant Levels Warm air blowing from your vents could also point to low refrigerant. This usually happens due to a leak somewhere in the system—something we see often in older Winston-Salem homes or systems that haven’t been serviced in a few years. What to do: This isn’t a DIY fix. Refrigerant should only be handled by certified professionals. If you hear hissing noises, notice ice on your refrigerant lines, or experience a steady decline in cooling performance, contact a trusted local HVAC company in Salem right away. 5. Compressor or Electrical Issues If your system is well-maintained but still blowing warm air, the problem might be with the compressor or electrical components. Heat, humidity, and high demand during the summer months can take a toll on even newer systems. What to do: Schedule a professional AC diagnostic. Our Salem-based team serves all of Forsyth County and can pinpoint the issue with your compressor or wiring quickly—before the problem gets worse.

As temperatures start to rise here in Morganton, NC, your air conditioner becomes more and more essential. The last thing you want is for your AC to break down during the peak of summer when you need it most. That’s why spring is the perfect time to watch for signs that your system might need a little TLC. At Gwyn Services, we’ve helped countless homeowners avoid major breakdowns by catching problems early. Here are the top signs your AC might need repair before summer hits. 1. Your AC Is Blowing Warm Air If your air conditioner is running but the air coming out of the vents isn’t cold, that’s a red flag. This could point to issues like low refrigerant levels, a failing compressor, or airflow problems. Don’t ignore this—your system should be keeping your home cool and comfortable. 2. Unusual Noises from the Unit A well-functioning AC unit should run quietly. If you hear grinding, squealing, banging, or rattling sounds, something is likely loose or broken inside the system. The sooner it’s checked, the better you can avoid more costly repairs. 3. Poor Airflow Throughout Your Home Weak or uneven airflow is often a sign that your air conditioner is struggling. This could be due to a clogged air filter, ductwork issues, or a malfunctioning blower motor. If some rooms feel warmer than others, give us a call for an inspection. 4. High Energy Bills for No Clear Reason If your utility bills are rising even though your AC usage hasn’t changed, it could be a sign your system is running inefficiently. A struggling unit has to work harder to maintain the set temperature, using more energy in the process. 5. Frequent Cycling On and Off Short-cycling—when your AC turns on and off frequently—can signal a range of problems, from thermostat issues to an oversized system. Not only does this impact comfort, but it also causes unnecessary wear and tear on your unit. 6. Bad Odors When the AC Runs Strange smells coming from your vents could be caused by mold or mildew in the system, burnt wiring, or even a pest problem. Spring is a great time to have your system inspected and cleaned to keep your indoor air fresh and healthy. 7. Excess Moisture or Leaks Around the Unit While some condensation is normal, puddles of water or refrigerant leaks are not. Leaks can damage your system and your home, and refrigerant issues should be addressed by a certified HVAC technician right away. Don’t Wait—Schedule Your Spring AC Inspection Today!
