An outside unit that hums while the fan stays still is the classic summer service call in Mount Pleasant, 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.

When to Call for AC Repair in Mount Pleasant

The sooner you notice these red flags, the easier and cheaper the fix. These are the signals our technicians see most often:

  • Vents blowing air that is barely cooler than the room
  • A burning smell or repeated breaker trips when the AC starts
  • Clicking or humming outside with no fan movement
  • Rising electric costs paired with a sticky, uncomfortable house
  • Ice on the refrigerant lines or a frozen indoor coil
  • The system short-cycling every few minutes without cooling the house
  • A hiss or gurgle from the lines, a common sign of leaking refrigerant
  • Water leaking around the indoor unit or from the ceiling below it

Early Action Saves Money

A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, call (843) 268-6989 and we'll take a look right away.

Our Approach

What Goes Into Our AC Repair

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. Topping off refrigerant without locating the leak only buys cold air until the charge leaks out again.

We service central air systems, heat pumps in cooling mode, and ductless mini splits from all major brands, and our trucks stock the summer failure parts: capacitors, contactors, fan motors, hard-start kits, and condensate pumps, so cold air usually returns before we leave the driveway. When a compressor has truly failed on an aging system, we say so plainly and lay out the repair-versus-replace math honestly. For fast AC repair anywhere in Mount Pleasant, call (843) 268-6989 and an experienced technician will be on the way.

Pricing

How Much Does AC Repair Cost in Mount Pleasant?

Most air conditioner repairs in Mount Pleasant land between $150 and $650. Small electrical parts like capacitors and contactors sit at the low end, while refrigerant leaks, coils, and compressors cost more. Mount Pleasant HVAC diagnoses the problem first and gives you a written price 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
  • 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.

RepairTypical costWhat it usually means
Capacitor replacementThe most common AC failure; outdoor unit hums but won't start$150–$400Most common repair, usually same visit
Contactor replacementWorn relay that stops the condenser from starting$150–$350Worn relay that stops the condenser from starting
Condenser fan motorOutdoor fan stops, compressor trips on high heat$300–$700Fan won't spin, unit overheats and shuts down
Refrigerant leak repair + rechargeVaries with where the leak is and how much charge is lost$300–$1,500Depends on leak location and refrigerant type
Evaporator coil replacementMajor repair; worth weighing against replacement on older systems$1,000–$2,500Major repair; worth weighing against replacement on older systems
Compressor replacementOn systems past 10–12 years, replacement usually makes more sense$1,500–$3,000Largest single repair; often weighed against a new system

Ranges are typical for these repairs; you get an exact quote before any work starts.

Step by Step

Our AC Repair Process

We follow a proven process to ensure every repair and installation is completed to the highest standards.

1

Testing First

Before we replace anything, we meter the electrical components, read the refrigerant charge with superheat and subcooling, and look over the coil, filter, and condensate line for the actual cause.

2

Clear Explanation & Price

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.

3

On-the-Spot Fix

Since the common summer failures, like capacitors, contactors, and fan motors, are already on board, most AC repairs are wrapped up during the first visit.

4

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.

FAQ

Frequently Asked Questions About AC Repair

Have a different question? We're happy to talk it through.

Talk to us: (843) 268-6989
Four problems account for most of these calls: low refrigerant from a leak, a frozen evaporator coil, a dead capacitor on the compressor or condenser fan, and leaky return ducts that let air bypass the coil. We test to find which one it is before replacing anything. Call (843) 268-6989 and we will track it down quickly.
Your evaporator coil is dropping below freezing. That happens when airflow falls off, typically from a dirty filter, a dirty coil, or a weak blower, or when the system is low on refrigerant. Continuing to run it can harm the compressor, so turn the AC off, let the ice melt, and call (843) 268-6989 so we can correct the underlying cause.
If the fault is a capacitor, contactor, motor, or drain issue, repair is usually the smart move at any age. If the compressor or evaporator coil has failed on a system past the twelve-year mark, replacement often wins, especially since older R-410A and R-22 systems cost more to keep charged. We show you the honest math. Call (843) 268-6989 for straight answers.
Usually the same day. Capacitors, contactors, and fan motors cause the bulk of summer breakdowns, and our trucks carry them, so most repairs are done in a single visit. Call (843) 268-6989 and we will get an experienced technician headed to your Mount Pleasant home.
Why It Matters

Why Professional AC Repair Matters

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.

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 any time 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.

Should You DIY or Call a Pro?

Simple checks are fine to DIY, but most heating and cooling repairs need professional tools, training, and experience.

FactorDIY AttemptProfessional Service
Refrigerant Leaks Adding refrigerant while it keeps leaking Leak found and fixed, then charge weighed in
Shock Risk Live 240V wiring and a charged capacitor Power verified off, capacitors discharged
Iced Coils Thawed and refrozen on repeat Cause of the icing traced and corrected
Diagnosis Guessing between look-alike faults Meters, gauges, and temperature clamps
Parts Close-enough capacitors and motors Ratings matched to the data plate
Result Short-lived relief Tested and confirmed under load

Prevention

AC Repair Prevention Tips

Taking preventive measures can help you avoid costly heating and cooling problems down the road. Start with these practical measures our team relies on:

  • Clear the condensate drain when you first turn on the AC each year
  • Rinse the outdoor condenser coil each spring and keep vegetation two feet back
  • Book a professional tune-up each spring before the first heat wave finds the weak parts
  • Never enclose the condenser; it needs open space on every side to shed heat
  • Change the filter monthly during cooling season; starved airflow is how coils freeze
  • Pay attention to buzzing or clicking when the AC starts, a common warning of a failing capacitor
  • Avoid shutting registers in unused rooms, which raises static pressure and stresses the blower
