When the summer heat cranks up in the Triad, the last thing you want is for your air conditioner to throw in the towel. At Gwyn Services, we’ve seen it happen time and time again: a tired, overworked AC system finally gives out—usually during the hottest week of the year. Before you're left sweating and scrambling for emergency repairs, here are some clear signs your air conditioner might be nearing the end of its life—and why now might be the right time to replace it. 1. It’s More Than 10–15 Years Old Most air conditioners have a lifespan of around 10 to 15 years, depending on how well they’ve been maintained. If your unit is creeping up in age—and especially if it uses outdated R-22 refrigerant (which is no longer manufactured)—it’s probably time to consider an upgrade. Newer models are far more energy-efficient, which means lower utility bills and better performance. 2. Frequent Repairs Are Adding Up If you’ve called in more than one repair technician over the past couple of summers, those service costs can start to outweigh the value of keeping your old system running. Constant repairs are a red flag that key components are wearing out—and it’s only a matter of time before something major fails. Tip: If a repair is more than 30–40% the cost of a new unit, replacement is often the smarter investment. 3. Your Home Isn’t Comfortable Anymore Are some rooms too hot while others feel like a freezer? Does your system seem to run constantly without ever quite catching up? These are signs your AC is losing efficiency—or it may not have been sized correctly in the first place. Inconsistent comfort is more than a nuisance—it could signal a system on the verge of failure. 4. Your Energy Bills Keep Rising If your power bill seems to rise every summer without a clear reason, your aging AC system could be the culprit. Older units work harder (and longer) to keep your home cool, which uses more energy and puts strain on your wallet. An ENERGY STAR®-rated system can cut your cooling costs significantly—and perform better while doing it. 5. Strange Noises, Smells, or Leaks Unusual sounds like grinding, rattling, or buzzing can indicate worn-out parts or failing components. Musty smells may mean mold in the ductwork, and any visible leaks could be refrigerant or condensate line issues—both of which can signal serious internal problems. Bottom line: If your AC is acting or smelling “off,” don’t ignore it. Don’t Wait for a Breakdown—Plan Ahead with Gwyn At Gwyn Services, we believe in helping our customers make informed, stress-free decisions. Replacing your AC system is a big investment, but it doesn’t have to be a surprise emergency. If you’re noticing any of the signs above, now is the perfect time to schedule a free consultation with one of our comfort specialists. We'll help you evaluate your current system, explore high-efficiency replacement options, and make sure your home stays cool and comfortable through every North Carolina summer. 📍 Proudly serving Winston-Salem and the surrounding Triad 📞 Call us today at 336-774-1818 or Schedule Service Online
Summer is flying by- celebrate with a Back to School Party from Gwyn Services!
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. When to Call in the Pros If you’ve ruled out the basics and your system is still underperforming, it’s time to call a licensed HVAC expert. Don’t wait until the next 90-degree day hits Winston-Salem.
