An outside unit that hums while the fan stays still is the classic summer service call in Myrtle Beach, SC, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.
Warm air from the vents can mean a failed capacitor, a refrigerant leak, a frozen coil, or a duct problem, and each one comes with a very different price to fix. That is why Myrtle Beach HVAC tests before touching anything. We meter capacitors against their microfarad rating, compare compressor and fan amp draws to the data plate, judge the refrigerant charge by superheat and subcooling instead of pressure alone, and inspect the coil, blower wheel, and filter whenever there is ice. Topping off refrigerant without locating the leak only buys cold air until the charge leaks out again.
Honest advice is part of every visit. If an aging system's compressor has failed, we explain the repair-versus-replacement math plainly and let you decide. Most of the time, though, the fix is simpler, and because our trucks stock capacitors, contactors, fan motors, hard-start kits, and condensate pumps, cooling is usually restored before we leave. We work on central air, heat pumps, and ductless mini splits from all major brands. Need AC repair in Myrtle Beach? Call (843) 268-6962 and an experienced technician will be on the way.

How Much Does AC Repair Cost in Myrtle Beach?
The typical AC repair in Myrtle Beach costs $150 to $650. The part that failed drives the price: a capacitor is a quick, inexpensive fix, while a coil or compressor is a major repair. Myrtle Beach HVAC diagnoses the problem first and gives you a written price before any work starts.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Capacitor replacementThe most common AC failure; outdoor unit hums but won't start | $150–$400 | The most common AC failure; outdoor unit hums but won't start |
| Contactor replacementWorn relay that stops the condenser from starting | $150–$350 | Worn relay that stops the condenser from starting |
| Condenser fan motorOutdoor fan stops, compressor trips on high heat | $300–$700 | Outdoor fan stops, compressor trips on high heat |
| Refrigerant leak repair + rechargeVaries with where the leak is and how much charge is lost | $300–$1,500 | Depends on leak location and refrigerant type |
| Evaporator coil replacementCorroded or leaking indoor coil | $1,000–$2,500 | Corroded or leaking indoor coil |
| Compressor replacementOn systems past 10–12 years, replacement usually makes more sense | $1,500–$3,000 | Largest single repair; often weighed against a new system |
Ranges are typical for these repairs; you get an exact quote before any work starts.
Factors That Change the Price
- How old the unit is and how easy its parts are to source
- Refrigerant type, because R-22 recharges are much more expensive
- Whether the repair is urgent, after hours, or can be scheduled
- Access to the equipment, like rooftop units or tight attic air handlers
On older systems we always compare the repair against a replacement, so you can make the call with real numbers. Questions about cost? Call (843) 268-6962.
When to Call for AC Repair in Myrtle Beach
Catching these issues early helps you avoid costly problems and protect your property. Here are the most common indicators that it's time to call a professional:
- Frost or ice forming on the copper lines or the indoor coil
- Bubbling or hissing noises that point to a possible refrigerant leak
- Room-temperature air from the registers even though the AC is running
- Clicking or humming outside with no fan movement
- Higher summer bills even though the house still feels warm and humid
- Puddles near the air handler or water stains on the ceiling beneath it
- Breaker trips or a burning odor at startup
- The system short-cycling every few minutes without cooling the house
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. At the first hint of a problem, reach out to Myrtle Beach HVAC at (843) 268-6962 for a fast inspection.

Why Hire a Professional for AC Repair?
Air conditioning repair concentrates several hazards in one cabinet. Capacitors store a charge that bites long after the breaker is off, condensing units run on 240-volt circuits, and the refrigerant loop is a sealed, pressurized system that federal rules do not permit venting to the air; working on it takes gauges, a recovery machine, and a vacuum pump, not a can from the internet. The diagnostic traps are just as real: a frozen coil looks like a refrigerant problem but is just as often an airflow problem, and refilling a leaking system without repairing the leak wastes money while acid and moisture quietly damage the compressor.
Professional service sees the full picture, not just the symptom. Our technicians meter electrical parts before replacing them, make charge decisions from measured superheat and subcooling, locate leaks with electronic detectors and dye, and check the filter, blower, and static pressure any time airflow could be the issue. The result is a repair that lasts the season instead of a guess that fails in three weeks. If your system is not worth saving, you will hear it from us directly, backed by numbers rather than a sales pitch.
How Our AC Repair Works
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's exactly how the AC repair process unfolds:
Full Cooling Diagnosis
Capacitors, the contactor, motors, and amp draws are all measured, the charge is checked through superheat and subcooling, and the coil, filter, and drain are inspected so the real failure is found.
Findings & Firm Quote
Nothing happens without your approval. We explain what broke and why, quote a firm price, and, if the compressor or coil has failed, walk you through repair versus replacement honestly.
Same-Visit Repair
Most AC fixes happen right away. We carry capacitors, contactors, fan motors, and other high-failure parts, so you are rarely left waiting on a parts order.
Test Under Load
Before we leave, we measure the temperature split, recheck amp draws and refrigerant charge, flush the condensate line, and run the system through a complete cooling cycle.
How to Prevent AC Repair Problems
Taking preventive measures can help you avoid costly heating and cooling problems down the road. Here are our expert recommendations:
- Leave vents open in every room, since closing them strains the blower
- Rinse the outdoor condenser coil each spring and keep vegetation two feet back
- A new buzz or click at startup often means a weak capacitor, so call before it fails
- Book a professional tune-up each spring before the first heat wave finds the weak parts
- Change the filter monthly during cooling season; starved airflow is how coils freeze
- Never enclose the condenser; it needs open space on every side to shed heat
- Flush the condensate drain line with the season's first use to head off clogs
Should You DIY or Call a Pro?
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Refrigerant Leaks | Recharge cans that ignore the leak | Leak repaired and correct charge restored by weight |
| Shock Risk | Stored capacitor charge and live 240V | Circuits tested dead before any work |
| Iced Coils | Same ice, again and again | Root cause found: airflow or charge |
| Diagnosis | Guesswork on faults that look the same | Instrument readings, not hunches |
| Replacement Parts | Parts that are almost the right rating | Ratings matched to the data plate |
| Result | Cold air until the next heat wave | Fix proven under full cooling load |
