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

You don't have to be a graduate from James Island Christian School near James Island, 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 James Island, 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 James Island, 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 James Island, 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 James Island, 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 James Island, 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 James Island, 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 James Island, 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 James Island, 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 James Island, 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.
Licensed HVAC Contractor James Island, SC

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.

JOHNS ISLAND — An undeveloped island that belonged to a Quaker colonist's family for 220 years will soon be home to 10 new households.

Hoopstick Island, a 55-acre private property between Kiawah and Johns islands, was first formally conveyed by an English royal land grant in July 1717 to Abraham Wright.

The land was part of a larger 96-acre property that Wright passed down through his female lineage until the family sold it in 1937.

More than 80 years and several owners later, an Atlanta-based investor and developer paid $7.5 million for the property that is zoned for a maximum of 10 estate lots — eight with deep-water access.

Reservations are now open for the first phase of sales.

SFG Hoopstick Island LLC, is an affiliate of developer Stonemont Financial Group of Atlanta, is the owner, according to Charleston County land records.

Sean McDonell, senior vice president with Stonemont Financial Group, said this is the company’s first venture into the Charleston market and was presented by a friend of the owner.

“Once we got our arms around it, it wasn’t necessarily that Charleston was never a target on our market list as much as it was the opportunity was so unique and that’s why we pursued it,” he said.

Charles McIntosh with The Cassina Group, which represented Stonemont in its 2022 purchase and is also handling the lots sales, said the previous owner of the property was looking for a private place to create a family compound. It bought Hoopstick, which is why the 10-unit development plan was already in place.

Stonemont saw no reason to change the plans, McDonnell said.

“One of the thoughts we had was you’ve got this undeveloped piece of property that dates back a long, long time," he said. "So we want to take our time and really think through what’s going to be developed here so that we preserve as much of the natural part of the island as possible. It would almost be a shame to move too quickly and make sort of uninformed decisions.”

During the three years of planning, McDonnell said his firm spent time with land planners, architects and builders, asking their ideas and experience in developing similar property — what worked and didn't or what they would have done differently.

The island will be sold in phases. The first four lots are listed, with one under contract. The asking price was $3.45 million for 20.11 acres — a mix of 4.61 acres of high ground and 15.5 acres of marsh.

The smallest of the four, with 4.03 acres of high ground and 8 acres of marshland, hit the market May 9 for $2.75 million. The other two are going for $3.2 million and $3 million and are between 6 and 8 acres.

Once developed, the island with over a mile of deep-water frontage along Bohicket Creek, will be gated, but McDonell said the plan is to keep the property as natural as possible.

The single existing causeway leading the island will be resurfaced with shell aggregate, not asphalt, he said. The enclave won’t have an amenity space, but will have a common green area for a potential garden.

Development plans also call for keeping as many trees as possible, McDonell said. Buyers can then design their houses and layouts based on the natural layout of the environment.

“There is a set of architectural guidelines for the property, but the vision is for the homes to be a Lowcountry style and blend with the surroundings,” McIntosh said.

Robertson Allen, founder of The Cassina Group, said he anticipates closing on all lots in the first part of 2026 given the demand for waterfront living and the lack of available property.

“We’re surrounded by water, but true deep-water opportunities are not a dime a dozen,” he said. “I feel like Hoopstick gives someone a unique opportunity to have a short-dock and an estate-sized piece of property very close to town.”

‘Going to save lives’: James Island funds children’s swim lessons

JAMES ISLAND, S.C. (WCSC) - School is out and summer is just around the corner, which means you may have a few fun days at Folly Beach or the pool already planned, but with that, there may also be some risks.

The South Carolina Department of Public Health says toddlers and preschool-aged kids are the most at risk for both fatal and nonfatal drowning incidents.

Though the state has few reported drownings, you may still have anxieties or fears involving swimming.

On Tuesday night, to help mitigate some of those worries, the Town of James Island and the Gullah Swim Academy are having a meet and greet for the instructors and swimmers in their new partnership program.

“It’s so important because you know, there’s always the chance of drowning if a child is out playing and slips and falls or goes into the water to retrieve a ball, something like that,” Mayor Brook Lyon said.

The lessons will allow up to 60 participants throughout the summer to learn how to swim, offering four Friday sessions over the next few months. Each day will have three 45-minute lessons at James Island Recreational Center.

The dates include June 6, June 13, June 27 and July 11.

“Everyone should know how to swim. It’s a real safety issue if you don’t know how to swim, living in the Lowcountry, especially on James Island,” she said.

Several local churches will also offer free transportation to and from lessons, including True Vine Tabernacle.

“Us being surrounded by so much water, you’ll be surprised by many of the people who don’t know how to swim,” Pastor William German said.

German said he knows there’s a population on the island that can’t afford lessons either, so being able to be a part of this will save lives.

Lyon said the town was able to cover the costs of 60 participants, coming out to about $4,500, which she said is worth every penny since it has been in the works since last year.

“Not only is it going to save lives, but it could teach them a lifelong recreation, hobby or skill. It’s always fun to go swimming, especially in the summer, as hot as it gets around here in Charleston,” Lyon said.

German said the reason for Tuesday is simple.

“You don’t know me unless you interact with me. And we become familiar with people, and I think that will settle down the fears, the unknown, and when we interact with one another, they make a connection,” German added.

Below is the list of local churches included in this partnership:

Longtime vacant Johns Island site could undergo $21M revitalization

JOHNS ISLAND, S.C. (WCSC) - A real estate group hopes to revitalize a former tomato packing facility on Johns Island to create a commercial and industrial complex.

Behind a rusted old fence sits the old DiMare tomato packing facility off Main Road. It’s been there sitting empty for a decade and a half, but Johns Island resident Pamela Frazier remembers it in its heyday.

“That’s my very first job I ever had in my life,” she said.

At just 16 years old, she was excited to get to work.

“I worked on the boxes, put the boxes together for the tomatoes to be packaged,” Frazier said.

The Charleston County Finance Committee’s meeting agenda shows Obelisk Real Estate Partners is looking to change that by investing $21 million dollars into the property.

Over the next two years, the plan would be to maintain the existing footprint of the property as well as make upgrades to the structures. They want to retrofit spaces for warehousing, storage, distribution, and light manufacturing use.

However, Frazier is concerned more about how it may affect the already-busy Main Road.

“It’s not going to be a good thing because the traffic on Main Road is awful,” Frazier said. “All my life, I’ve lived here and I’ve never seen so much cars, the road is damaged, you have a hard time getting to, and people are late for work and other things. It’s not needed.”

She and others who have lived on the island for decades said back when the tomato packaging facility was still operating, the road was not nearly as busy as it is now.

Frazier prefers the site stay empty.

“I would hope they continue with what they do. That’s where the firefighters go for their training so I figured they would keep it for that,” Frazier said.

Thursday’s agenda refers to the potential project as an opportunity to bring economic development and jobs to the neighborhood.

The property has not officially been sold yet. Charleston County’s Finance Committee meets on Thursday to discuss the Economic Development Abandoned Building Special Tax Assessment.

Kiawah Island developers look to expand on Johns Island, including residential community and golf course

JOHNS ISLAND, S.C. (WCBD) – Kiawah Island developers are proposing a plan to expand a new community on Johns Island.

Orange Hill Tract is about 933 acres of land between Bohicket Road and River Road. Charleston County previously approved development plans there in 2004, but since, it has been sold to South Street Partners. They are requesting approval from the County to build a new residential community and 18-hole golf course, part of the Kiawah Island Club. The group and county are also working on a development agreement, which officials said makes this deal more attractive.

“Our community development was able to secure a significant amount of funding for affordable workforce housing for Johns Island, nearly a million dollars. I think there was another $500,000 for Sea Island Habitat for Humanity. Additionally, St. John’s Fire Department is getting half the cost of a fire engine from the developer and our Charleston County EMS is basically getting half the cost of an ambulance covered,” Joe Boykin, county councilmember for District 8, said.

Also, Developers tell News 2, around 60% of their employees live on Johns Island and Wadmalaw Island. They said this gives their employees another opportunity to make their commute closer to home and be present in the community with their contributions.

The revised plan coming from the South Street Partners includes a greater focus on preservation, by keeping over 80% of live oaks on the property, improving stormwater management, and reducing the numbers of homes originally proposed.

“That was done as a result of site analysis that suggested lower density and more modest home sites rather than big home sites and big homes. More modest home sites appropriate for the setting. More aligned with the character of Johns Island in terms of the nature of homes there,” said Mark Permar, Kiawah Island master planner and architect.

Additionally, by reducing the amount of homes, there will also be less impacts from previously planned roads on the property. The group has also decided to put the community’s entrance on the less congested roadway.

“The access point was instead of Bohicket Road, we felt the more after we did an assessment we felt the more appropriate access point would be off of River Road,” Permar said. “Part of that was a reaction to the ever increasing traffic count on Bohicket Road that we’re all familiar with.”

The Kiawah Partners own and manage the Beach Club and Cassique Club, and Permar said they continue to be a community involved group. When asked about possible resident concerns, Boykin added that this is a better option than allowing for an outside developer to come in and sell.

“The developer’s been pretty sensitive to our concerns as Johns Islanders and wanting to keep our sense of place. So, again the concessions they made in reduction to how many units and the rearrangement of how they’re putting in this development I think were sensitive to our concerns,” said Boykin.
