Most AC breakdowns in Mount Pleasant start with a small part: the run capacitor. It helps start the compressor and condenser fan, loses strength slowly over the years, and tends to give out on the hottest afternoon, which is why so many service calls begin with an outdoor unit that hums while the fan sits motionless. Other frequent culprits include contactors with pitted, burned points, fan motors whose bearings have run dry, slow refrigerant leaks that steadily rob capacity, and evaporator coils that turn into blocks of ice once a dirty filter chokes the 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 Mount Pleasant 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. Adding refrigerant without locating the leak only buys cold air until the charge leaks out again.
Central air, heat pumps running in cooling mode, and ductless mini splits from every major brand are all part of our daily work. Because our trucks carry capacitors, contactors, fan motors, hard-start kits, and condensate pumps, most AC repairs are completed the same visit. If the compressor has failed on an older system, we tell you so directly and show you the numbers on repairing versus replacing. Call (843) 268-6989 for fast AC repair in Mount Pleasant.

How Much Does AC Repair Cost in Mount Pleasant?
Most air conditioner repairs in Mount Pleasant land between $150 and $650. The part that failed drives the price: a capacitor is a quick, inexpensive fix, while a coil or compressor is a major repair. Mount Pleasant HVAC diagnoses the problem first and gives you a written price before any work starts.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Capacitor replacementMost common repair, usually same visit | $150–$400 | Most common repair, usually same visit |
| Contactor replacementWorn relay that stops the condenser from starting | $150–$350 | Burned or pitted switch that powers the outdoor unit |
| Condenser fan motorFan won't spin, unit overheats and shuts down | $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 | Varies with where the leak is and how much charge is lost |
| Evaporator coil replacementCorroded or leaking indoor coil | $1,000–$2,500 | Major repair; worth weighing against replacement on older systems |
| Compressor replacementLargest single repair; often weighed against a new system | $1,500–$3,000 | On systems past 10–12 years, replacement usually makes more sense |
These are common price ranges, not quotes. We confirm the exact price after diagnosing your system.
Factors That Change the Price
- The age of the system and whether parts are still readily available
- Refrigerant type, because R-22 recharges are much more expensive
- Whether the repair is urgent, after hours, or can be scheduled
- How hard the equipment is to reach, such as attics, crawlspaces, or rooftops
When a quote climbs toward the cost of replacement on an older unit, we'll lay out repair and replacement prices together, with no pressure either way. Call (843) 268-6989 for a quote.
When to Call for AC Repair in Mount Pleasant
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. These are the signals our technicians see most often when a problem is underway:
- Warm or room-temperature air blowing when the thermostat calls for cooling
- A burning smell or repeated breaker trips when the AC starts
- The outdoor unit humming or clicking but the fan not spinning
- Cooling bills climbing while the house stays sticky and warm
- An iced-over evaporator coil or frozen refrigerant lines
- An AC that turns on and off every few minutes but never cools down the house
- Bubbling or hissing noises that point to a possible refrigerant leak
- Water leaking around the indoor unit or from the ceiling below it
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. Call Mount Pleasant HVAC at (843) 268-6989 at the first sign of trouble.
AC Repair FAQ
The Benefits of Professional AC Repair
An air conditioner packs several hazards into one cabinet. The capacitor can deliver a painful shock long after the breaker is off, the condensing unit is wired for 240 volts, and the refrigerant circuit is a sealed, pressurized loop that federal rules forbid venting. Servicing it properly takes gauges, a recovery machine, and a vacuum pump, not a DIY recharge can. Diagnosis has its own traps. A frozen coil is as likely to be an airflow issue as a charge issue, and recharging a system that still leaks wastes money while moisture and acid work on the compressor.
What you get from a pro is a repair that holds. Our experienced technicians find leaks with dye and electronic detectors, base every charge decision on superheat and subcooling, test electrical parts with a meter before condemning them, and measure static pressure and inspect the blower and filter whenever airflow is in question. Parts-cannon fixes tend to bring you back in a few weeks. Ours are built to last through the heat. And if the numbers say replacement is the better call, we show you those numbers honestly, without pressure.
How Our AC Repair Works
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's what you can expect when you choose Mount Pleasant HVAC:
System Diagnosis
Capacitors, the contactor, motors, and amp draws are all measured, the charge is evaluated through superheat and subcooling, and the coil, filter, and drain are inspected so the real failure is found.
Findings & Firm Quote
We show you what failed and why, then give a firm price before any work begins. If the compressor or coil points toward replacement instead, we lay out the honest math.
Same-Visit Repair
Our trucks carry capacitors, contactors, fan motors, and the other parts that fail most in summer, so the large majority of AC repairs are completed on the spot.
Test Under Load
We confirm a healthy temperature split across the coil, verify amp draws and charge, clear the condensate line, and watch a full cooling cycle before we leave.

Get Help: (843) 268-6989How to Prevent AC Repair Problems
A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Start with these practical measures our team relies on:
- Start each cooling season by flushing the condensate line so algae cannot block it
- Rinse the outdoor condenser coil each spring and keep vegetation two feet back
- Have the AC serviced every spring, ahead of the first real heat
- Never enclose the condenser; it needs open space on every side to shed heat
- Swap filters monthly while the AC is running hard to keep the evaporator coil from icing
- Pay attention to buzzing or clicking when the AC starts, a common warning of a failing capacitor
- Keep supply and return vents open; closing rooms raises static pressure on the blower
DIY vs. Professional AC Repair
While some minor tasks like changing filters or checking a thermostat can be handled by homeowners, most HVAC work involves refrigerant, gas combustion, and high-voltage electricity, jobs that call for professional expertise. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Refrigerant Leaks | Recharge cans that ignore the leak | Leak found and fixed, then charge weighed in |
| Shock Risk | Live 240V wiring and a charged capacitor | Circuits tested dead before any work |
| Iced Coils | Thawed and refrozen on repeat | Airflow or charge problem identified and fixed |
| Diagnosis | Picking a likely part and hoping | Meters, gauges, and temperature clamps |
| Parts | Close-enough capacitors and motors | Ratings matched to the data plate |
| Outcome | Cold air until the next heat wave | Tested and confirmed under load |
