My AC Isn't Working. What's Going On?

You don't have to be a graduate from Sewee Visitor Environmental Education Center near Awendaw, SC, to know when something is wrong with your air conditioning. Being aware of common AC unit problems helps prevent breakdowns. Who wants to be stuck inside during a hot summer in Awendaw, SC without AC? Keep your eyes and ears peeled for these common issues:

01Your Air Conditioner Isn't Turning On

Waking up in the morning to find that the air conditioner won't turn on is incredibly frustrating. No matter how low you set the thermostat, the AC still refuses to engage.

AC Repair Technician Awendaw, SC

Cause

At times, this issue arises due to a tripped circuit breaker. Additional causes may include a defective thermostat or loose wiring.

Solution

Some AC problems can be fixed without any training. This is not one of those issues. Do not attempt to do any wiring work on your own. Call a respected HVAC company like J.W. Long Mechanical for AC repair in Awendaw, SC. Our techs have specialized equipment that can help diagnose the issue and advanced training to perform fixes.

02Your AC Won't Stop Running

This problem is a complete 180 from the entry above. It's completely normal for your air conditioner to work harder during hot weather, but it should still turn off at regular intervals. Addressing an AC that won't shut off is essential for protecting its key components and keeping your energy bills in check.

Air Conditioning Repair Service Awendaw, SC

Cause

This problem can stem from a variety of sources and is very common. You might be dealing with a faulty thermostat, a malfunctioning compressor, clogged air filters, or even issues with electrical components.

Solution

To start, try switching off the thermostat fan to check if that turns off the air conditioner. If it doesn't, reach out to our HVAC company. Our experts are skilled at quickly identifying issues and often handle repairs on the first visit.

03Your AC Unit Blows Out Hot Air

Why is your air conditioning unit blowing out warm air instead of cool? The last thing you want is to feel even hotter while you're already sweating inside your home. Unfortunately, this issue can happen even during the peak of summer.

Emergency AC Repair Awendaw, SC

Cause

Warm air could indicate a dirty air filter, blockages in the ducts, or debris that is leading to the compressor overheating. It's also possible that your refrigerant levels are low.

Solution

Change your air filters every one to two months to avoid clogs, and make sure to have your ducts cleaned at least once a year. Before you top off the refrigerant in your AC units, always have an AC repair specialist check for leaks. At J.W. Long Mechanical, our HVAC techs are very familiar with this task and can actually help save you money in the long run.

04HVAC System Leaks

Homeowners often find it challenging to detect refrigerant leaks since they typically occur within the coolant lines. However, if you notice brightly colored stains near your AC unit, it could indicate trouble. While some condensation outside the air conditioner is normal, excessive moisture may suggest a water leak.

HVAC Maintenance Awendaw, SC

Cause

Over time, the lines and connections in an AC system can deteriorate, which often results in refrigerant leaks. Water leaks are generally caused by blocked drainage pipes and malfunctioning condensate pumps.

Solution

If you spot a refrigerant leak, make sure to turn off the unit and reach out to our HVAC company in Awendaw, SC as soon as possible. Low refrigerant levels can lead to serious damage to the compressor, which is one of the costliest parts to replace. Thankfully, regular maintenance checks can uncover these issues, and our certified technicians can recharge the refrigerant as needed.

05Constant On and Off Cycles

This issue is commonly referred to as short cycling. Instead of running through a complete cooling cycle, the air conditioner repeatedly starts and stops. This can be a significant problem that may lead to compressor damage.

Residential Air Conditioning Repair Awendaw, SC

Cause

Sometimes, the issue can be as straightforward as dirty air filters or a thermostat that needs recalibrating. It's also possible that your air conditioner is simply too powerful for the size of your home.

Solution

The first step to solving this problem is to call an AC repair company to come out and look at your HVAC system. At J.W. Long, our team will diagnose your problem and provide cost-effective options for you to consider. If your AC system isn't the right fit for your home, new AC installation may be in store - especially for long-term savings.

AC Repair vs. Air Conditioning Installation in Awendaw, SC

Which is best: AC repair or new AC installation? The answer to that question will change depending on your circumstances. Some of the most logical reasons to go with AC repair instead of having a new unit installed are:

  • Age of AC Unit: If your air conditioner is less than 10 years old, it still has life.
  • One-Off Repair: If an HVAC technician from J.W. Long suggests a repair for a one-off issue, there's really no need to replace your unit. If the issue starts to happen more frequently, you may want to change your mind.
  • Great Deals and Financing: Before you start calculating the price of repairs, consider that J.W. Long Mechanical offers regular specials and financing for our services, which may make a repair far more feasible.

Here are a few of the biggest reasons to have a new AC unit installed instead of paying for perpetual repairs:

Efficiency

Forget about the system breaking down. Even before your old air conditioner quit on you, it was already racking up some shocking electricity bills. For an aging system, there's only so much regular maintenance can accomplish. Eventually, it might be time to consider a new system, especially when you weigh the benefits of energy efficiency.

Boost the Value of Your Home

Even if you're not considering selling your home at the moment, installing a new air conditioner can boost your property's value if you ever decide to sell. It might even be a key factor in securing a buyer rather than losing out on a sale.

The Right Price at the Right Time:

It's not just true for repairs-it's equally relevant when considering new air conditioning systems. At J.W. Long Mechanical, we often run specials on new AC installations and even offer financing that can help you stick to a budget. If the cost of repairing your current system is nearing the price of a new unit, don't hesitate to invest in a new air conditioner. You'll likely recoup the price difference through energy savings.

SC’s most pressing environmental issues come to a head at the ‘Gateway to Cape Romain’

AWENDAW — Drive north on U.S. Highway 17, past the shopping centers and subdivisions, and you’ll come to a small town that sits at the proverbial crossroads of South Carolina’s most-pressing environmental issues. Here the Milky Way still shines at night, the wetlands teem with life, and the trees grow dense enough to create a near-perpetual dusk in the forest below.

But as Charleston County is reshaped by a fast-growing population and rising seas, the future of Awendaw and its wild spaces is in an uneasy limbo, and there’s no easy path towards a solution.

In this small town, anxieties about over-development collide with increased flooding, leaky septic tanks and the threat of wildfires. All of those issues are playing out in a town wedged between two of South Carolina’s most-diverse ecosystems: the Francis Marion National Forest and Cape Romain National Wildlife Refuge.

The Post and Courier’s Rising Waters Lab focuses on impacts of climate change and related policies and practices. It is supported by donations and grants to the nonprofit Public Service and Investigative Fund, whose contributors are subject to the same coverage we apply to everyone else. For more information and to make a donation, go to postandcourierfund.com. To sign up for our newsletter, click here.

As the U.S. government changes the playbook for federal land management — the Trump administration plans to increase logging in Francis Marion and has cut federal positions across South Carolina — Awendaw is literally caught in the middle.

“We’ve got the Department of Agriculture on the west, the Department of Interior on the east, and this oddly-shaped town of Awendaw is the gateway between those two,” said recently-elected Mayor Chris Crolley.

Awendaw’s adaptation strategy largely depends on nature-based, green solutions and ordinance overhauls, he said. The town recently became the second community in South Carolina to adopt a local wetlands protection ordinance in response to the Trump administration’s plan to deregulate previously-protected areas.

In Awendaw, Blake Scott sees a developing “road map” for other communities.

“ I see Awendaw as a perfect example of conservation on the human scale,” said Scott, the co-founder of the Charleston-based M.A.R.S.H. Project, a grassroots conservation group that works to protect Charleston’s salt marshes. Scott noted that Awendaw, population 1,600, is about the same size as many of Charleston’s neighborhoods.

“ We see that as a functional scale for us to achieve environmental victories,” Scott continued. “If Awendaw can do it, we hope that we could do it at our neighborhood level and then mushroom out from there to Charleston's various neighborhoods.”

Cape Romain’s gateway

Spanning 22 miles and roughly 66,000 acres, the Cape Romain National Wildlife Refuge is a near-pristine ecosystem of wetlands, islands, shores and maritime forests. The Cape is a biodiversity hotspot home to the state’s most-active nesting sites for loggerhead sea turtles and nearly 300 migratory and year-round bird species, several of which are considered "Tipping Point Species" that have lost at least half their population in the last 50 years.

While the refuge is managed by the Department of Interior, the surrounding communities play a significant role in safeguarding its water quality and ecosystem. Runoff from Awendaw washes directly into Cape Romain, and development along the border of the refuge has been a simmering source of tension in the community.

"Lands surrounding the Refuge are crucial for maintaining habitat and water quality by acting as buffers for the waters, marshes, and barrier islands of the Refuge," Sherri Fields, the conservation director for Audubon South Carolina, wrote in an email. "If these buffers are degraded by construction and pollution, habitats in the Refuge will also be affected, which will have negative consequences for bird populations that are already suffering."

The National Parks Service considers over half of the refuge a “Class 1 National Wilderness Area.” That status grants it additional Clean Air Act protections and means that, theoretically, the Cape is supposed to have some of the cleanest air in South Carolina.

“Awendaw is the gateway to Cape Romain National Wildlife Refuge,” Crolley said. “For Awendaw to be positioned so close to Cape Romain — it means something. There’s a responsibility inherent in that.”

In addition to his new role leading the town, Crolley owns and operates Coastal Expeditions, a local business that offers eco-tours of Charleston County’s tidal wetlands and ecosystem. The company also has a nonprofit arm, the Coastal Expeditions Foundation.

The foundation does conservation work within Cape Romain, work Crolley said is critical these days.

But limited funding for the National Wildlife Refuge system has been a challenge throughout several presidential administrations, Crolley said. He bluntly described it as a persistent “lack of give-a-sh- -” from Washington, D.C.

“ They're completely understaffed,” he said. “I think their charter says they're supposed to have 14 people, and they have two.”

If you include a regional manager in that count, he said, it raises the level of staffers at Cape Romain to three. The U.S. Fish and Wildlife Service — which is under the Interior Department and manages the Cape Romain Refuge — declined to comment on current staffing levels at the refuge, or about what the pre-Trump administration staffing levels were.

"The U.S. Fish and Wildlife Service remains dedicated to conserving America’s wildlife and natural habitats while promoting access, use, and enjoyment of public lands by the American people, all while upholding federal responsibilities with efficiency and accountability," an agency spokesperson wrote in a statement.

Awendaw, fearing spillover growth from Mount Pleasant, plans to extend its halt on new subdivisions

AWENDAW — Rural and lightly populated, this town on Mount Pleasant’s northern border has been facing increasing development pressure and is poised to extend a moratorium on subdivisions and zoning changes for another year.

For nearly two years the moratorium has prevented land from being divided into more than five pieces, effectively stopping the creation of subdivisions. For example, someone with a 100-acre piece of land couldn't carve it up into dozens of home sites while the moratorium is in force.

"In two years the population of Awendaw will double because of the developments allowed over the past 15 years," Mayor Chris Crolley said. "That's not sustainable."

Extending the moratorium would give the town another year to rewrite zoning and land-use rules to conform with Awendaw's latest Comprehensive Plan, a state-required planning document. The moratorium would not prevent construction where it's already allowed, but would prevent changes in land-use rules through zoning while also blocking larger subdivisions.

Councilman Kent Prause said that during the ongoing moratorium the town has raised the minimum size of a residential building lot with public water and sewer service from 12,500 square feet to 21,500 — nearly half an acre. The town also set new rules to protect wetlands and regulate septic systems.

Temporary moratoriums have seen increasing use across South Carolina as a tool to pause development, sometimes to allow time for new rules to be developed, other times to allow for infrastructure to catch up. The state has had the fastest-rising population in the nation in recent years.

Mount Pleasant had a moratorium on multi-family buildings for seven years; Berkeley County had a moratorium on large-scale developments; Anderson County blocked all new housing for 90 days in 2025; North Augusta put a 2-and-a-half-year halt to new apartment buildings, the list goes on.

Prause was Mount Pleasant's zoning administrator for decades, and has lived in Awendaw for 29 years. He said that while campaigning for office he knocked on hundreds of doors and "the two things I heard most were: 'We don't want to be another Mount Pleasant, and we just want to be left alone.' "

Prause led the charge for the first moratorium in 2024.

"We haven't really had anyone speak against it at (recent) public meetings," he said.

Crolley noted that a moratorium is temporary, though just how temporary remains to be seen. If approved at a special town council meeting and public hearing on Feb. 26 at 9 a.m., it would be the second one-year extension of Awendaw’s 2024 moratorium.

“Our Comprehensive Plan got ratified last year," said Crolley. "Given that we went through that whole process and have our template to work from, now it’s time to get the zoning in line and the ordinances to protect the wetlands and trees."

Awendaw has fewer than 1,800 residents and didn't have a full-time planning official until October 2025, according to Town Administrator Katharine Watkins.

While neighboring Mount Pleasant's population works out to 1,930 people per square mile, the number in Awendaw is less than 100. Residents there have seen how development can change a town.

Mount Pleasant had 5,100 residents in 1960. Over the next 30 years the town’s population grew nearly six fold, to 30,100, and in the next 30 years it tripled, to 90,801 in 2020.

“These developers aren’t in it for the wellbeing of the community," said Crolley. "They’re not from around here."

Mount Pleasant has taken many steps to limit growth and development, with annual limits on building permits, height and size restrictions on buildings, and the moratorium on multi-family housing that lasted seven years. But most of those things came after most of the available land in the town had been developed.

Like a growing number of South Carolina communities, Awendaw has set out to firmly regulate development before it takes place.
