If you've spent a summer in the Piedmont Triad, you know the feeling: you step outside at 7 AM and the air is already heavy before the day has even started. When the AC fails on top of that, it isn't just an inconvenience. It's a race against the humidity, and every hour matters.
Webb Heating, Air Conditioning & Electrical has been the Triad's first call for AC repair since 1978. Our technicians are NATE-certified, dual-licensed in HVAC and electrical, and based right here in the 336.

Not every AC problem announces itself with a breakdown. Some of the most common issues show up as subtle changes in how your home feels or sounds.
Here's what to watch for:
- The "Humidity Hangover": The air from your vents is cool, but your Greensboro home still feels sticky and close. This usually points to a failing evaporator coil, low refrigerant, or a system that's short-cycling before it can pull moisture from the air.
- The "336 Squeal": High-pitched squealing or grinding noises from the indoor or outdoor unit often indicate blower motor bearing failure. Don't wait on this one. Bearing failure tends to escalate quickly.
- Short-Cycling: If the unit kicks on and off every few minutes, it may be overheating due to a pollen-clogged condenser coil or a failing thermostat. Short-cycling puts significant wear on the compressor with every start.
- The "Warm Breeze" Mystery: Air is moving but it isn't cold. This frequently points to a failed start capacitor, one of the most common AC repairs we see after a Piedmont thunderstorm, or a refrigerant leak that's slowly robbing the system of its ability to cool.
- Ice in July: Frost or ice on the copper lines or indoor unit in the middle of summer signals restricted airflow or low refrigerant. The system is freezing itself up and will stop cooling entirely if left running.
- The "Musty" Arrival: A damp or dirty-sock smell when the system starts typically indicates mold or bacterial growth on the evaporator coil or in the condensate drain line, both of which thrive in North Carolina's humid summers.
If any of these sound familiar, the problem is unlikely to resolve on its own. Early diagnosis is almost always less expensive than waiting.
Our AC Repair Process: The Webb Standard
A lot of HVAC companies show up, swap a part, and leave. Webb's process is built around getting it right the first time.
- The Clean Arrival: Our technicians arrive in marked vans wearing floor-protecting booties, keeping North Carolina red clay off your floors. Before opening anything, we ask about the history: what changed, when it started, and whether anything happened right before the problem appeared.
- The Full-System Diagnostic: We don't guess. We check electrical vitals including amperage draw on the motors, measure refrigerant pressures, inspect capacitors and contactors, and assess the evaporator and condenser coils. The goal is to find the actual cause, not just the most visible symptom.
- Upfront Transparency: Before a single tool is turned, you get a clear, flat-rate price. No Greensboro guesswork, no surprise line items when the invoice arrives. If we find additional issues during the repair, we tell you before we act on them.
- The Precision Fix: We use high-quality parts and restore the system to factory specifications. For any refrigerant work, that means verifying charge with superheat and subcooling measurements, not just topping off and hoping for the best.
- The Safety Audit: We check for hidden electrical causes that a standard HVAC contractor wouldn't be equipped to address, including loose breakers, pitted contactors, and undersized disconnects that may be the real reason a component failed.
Every step is completed before we consider the job done.
Get Your AC Up and Running with Webb's AC Repair Services
Webb has been repairing air conditioners across the Piedmont Triad since 1978, from the mid-century neighborhoods of Starmount and Sedgefield to the growing communities of Davie County. Whether you need a same-day repair or a full system assessment, our team is ready.
We offer Home Service Agreements for homeowners who want priority scheduling and annual maintenance built in, and financing options if a larger repair or replacement makes sense. If it's time for something new, our AC installation page covers what that process looks like. For routine upkeep, see our AC maintenance page. And if air quality has been a concern alongside the repair, our IAQ Services page is worth a look.

The most common causes are low refrigerant, a failed capacitor, or a frozen evaporator coil. Low refrigerant is often a sign of a leak somewhere in the system, not just a matter of topping it off. A technician needs to find and fix the source before recharging. If the system is running but producing no cold air at all, shut it off and call for service. Continued operation can cause compressor damage.
It depends on how much and how fast. A small amount of condensation near the air handler is normal in humid weather. Active water dripping or pooling near the drain pan usually means the condensate drain line is clogged, which is common in Davie County and Greensboro homes during high-humidity months. Left unaddressed it can lead to water damage and mold growth. It warrants a same-day call, even if it isn't a middle-of-the-night emergency.
A useful rule of thumb: if the repair cost exceeds half the value of the system and the system is more than ten years old, replacement is often the better investment. Newer SEER2 systems are significantly more efficient than equipment from even a decade ago, and the energy savings can offset replacement costs over time. Webb will give you an honest assessment of both options. Our AC services page covers the full picture.
Short-cycling is usually caused by a clogged condenser coil, a refrigerant issue, a failing thermostat, or an oversized system that hits the setpoint temperature before completing a full cycle. An oversized system is particularly common in older Triad homes where a larger unit was installed thinking bigger meant better. It doesn't, and the short-cycling that results prevents the system from ever running long enough to dehumidify properly. A proper diagnostic will identify the cause.
