AC Repair in North Myrtle Beach
On the Grand Strand, a broken air conditioner isn't an inconvenience, it's an emergency by mid-afternoon. The temperature climbs, the humidity follows, and the whole house starts to feel damp. Coastline repairs central air conditioners and the cooling side of heat pumps throughout North Myrtle Beach, Little River and the Brunswick County beach towns. We track down the real cause, fix it right the first time, and when an old unit has truly run its course, we replace it with a system sized to keep your home cool and dry.

Air Conditioner Problems We Repair
Most AC calls on this coast fall into three groups: the system runs but doesn't cool, the system won't run at all, or there's water where there shouldn't be. Each one has a short list of usual suspects, and an experienced tech can usually narrow it down within minutes of arriving.
Warm Air or Weak Cooling
Low Refrigerant
An air conditioner doesn't burn through refrigerant over time. It's a sealed system, so if it's low, there's a leak. The most common spots are the indoor coil, the outdoor coil and the service valves where the copper lines connect. Adding refrigerant without finding the leak means paying for the same problem again next summer, so we find the source and give you options to fix it properly.
Dirty or Frozen Coils
The outdoor coil has to release the heat your AC pulls out of the house. When it's matted with pollen, grass clippings and dirt, the system runs hotter and cools less. Indoors, a coil that freezes into a block of ice usually means not enough air is moving across it, often from a clogged filter or a weak blower, or that the system is low on refrigerant. If you see ice on the copper lines, turn the cooling off, set the fan to "on" to help it thaw, and call us.
The AC Won't Turn On
Capacitors and Contactors
The capacitor gives the compressor and fan motor the jolt they need to start, and the contactor is the switch that turns the outdoor unit on when the thermostat calls for cooling. Both wear out, especially after long stretches of 90-degree days. Here in the South, we also find fire ants packed into contactors more often than you'd believe; they're drawn to the electrical current and can keep the switch from closing.
Thermostat, Wiring and Safety Switches
Sometimes the equipment is fine and the signal isn't getting through. A dead thermostat battery, a loose wire, a tripped breaker or a safety switch that has shut the system down will all look like a dead AC. We check the simple things first so you don't pay for parts you don't need.
Water Leaking Indoors
Clogged Condensate Drain
Your air conditioner pulls a surprising amount of water out of humid coastal air, and all of it has to drain away through a small pipe. Over a summer, algae and sludge can build up inside that line until it clogs, and the water backs up into the drain pan, the closet or the ceiling below an attic unit. Many systems have a float switch that shuts the AC off when the pan fills, which is better than a wet ceiling but still leaves you without cooling. We clear the line and make sure the safety switch works.
Rusted or Cracked Drain Pan
On older systems, the metal pan under the indoor coil can rust through and leak even when the drain line is clear. A replacement pan, or a secondary pan under an attic unit, protects the ceiling.
AC Replacement and New Installation
When repairs stop making financial sense, a new system is the next step, and it's a good time to rethink what you have. A heat pump cools exactly the way an air conditioner does and also heats efficiently through our mild winters, so many homeowners replacing an old AC and electric furnace choose a heat pump instead.
Choosing the Right System
Proper Sizing
Bigger isn't better. An oversized air conditioner cools the air so fast that it shuts off before it has time to pull moisture out, and the house ends up cold and clammy, which is the exact opposite of what you want on the coast. We size systems with a load calculation that looks at the house itself, not just the old unit's label.
Efficiency and Humidity Control
SEER2 is the cooling efficiency rating, and with a cooling season as long as ours, a higher number pays off faster than it does up north. Two-stage and variable-speed systems take it further by running longer at low speed, which keeps temperatures steady and wrings more moisture out of the air.
Installation Done Right
A new air conditioner only performs the way it's rated if it's installed correctly. That means sealing and pressure-testing the refrigerant connections, pulling a deep vacuum to clear moisture and air out of the lines before the refrigerant goes in, setting the charge to the manufacturer's specs, running a proper drain with a working safety switch, and making sure your ductwork can move the air the new system needs. Coastline is home of the 12-Year Labor Warranty; ask which installations qualify. For the full picture on sizing and efficiency, see heat pump replacement and installation.
Cooling a Home on the Coast
Air conditioners here run far more hours a year than they do inland, which means every weakness shows up sooner. Two coastal situations come up every year. After a tropical storm or heavy flooding, an outdoor unit that sat in standing water should be checked before it's turned back on, because water in the electrical components can cause serious damage. And in homes that still feel muggy with the AC running, a whole-home dehumidifier can take care of what the air conditioner alone can't. A maintenance plan helps you head into summer with the system checked and the drain line clear. Coastline is the North Myrtle Beach heating and cooling company that homeowners call when the AC can't wait.
AC Repair Questions
How often should I change my air filter?
Check it every month during the heavy cooling season and replace it whenever it looks gray or dusty, following the filter manufacturer's guidance. A clogged filter is one of the most common reasons we find frozen coils and weak airflow.
Why does my house feel cool but still damp?
The usual culprits are a system that's too big for the house, a thermostat fan set to "on" instead of "auto" (which blows moisture back off the coil), or a home that simply needs extra dehumidification.
Should I replace my old AC with a heat pump?
Often, yes. A heat pump handles cooling the same way and adds efficient heating, which can let you retire an old electric furnace. We'll compare both options for your home.
