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.

James Island, Beckham lose realignment appeal; Charleston Math & Science, Palmetto win

Four area high schools made their case regarding South Carolina High School League reclassification decisions on Tuesday, appealing their classification assignments to the league’s Executive Committee. Two won their appeal.

Charleston Charter School for Math & Science and Palmetto Scholars Academy were successful in their attempt to remain in Class A rather than move up to Class AA as assigned by the league. James Island and Lucy Beckham were denied in their attempt to move from Class AAAAA to Class AAAA.

Classification assignments are based on 45-day enrollment figures for grades 9-11. Realignments take place every two years. For the second time, a multiplier of three was used in counting students from outside assigned attendance zones, meaning each student from outside the assigned zones were counted three times. Competitive advantage and geographical considerations also are factors.

Schools can appeal the decisions of the Executive Committee to an appellate panel on Jan. 15-16. James Island and Lucy Beckham are expected to make their case to the appellate panel.

In the current realignment, the SCHSL revamped the number of schools in each classification, making Class A the largest classification while trimming the number of schools in the other four classes. Class AAAAA was split into two divisions for the 2025-26 cycle but decreased in size by 10 schools from 54 to 44 and moved back to one division. Class A will likely move to two classifications and will include 66 schools.

Several AA schools were reassigned to Class A for the coming cycle, but Charleston Charter and Palmetto Scholars Academy were moved up from Class A to AA with Charleston Charter listed as the largest school in AA. Despite the attendance numbers, CMS argued that playing in AA would put their athletes at a competitive disadvantage. The school offers fewer athletic teams and has a significantly lower number of athletes. CMS did not field a football team this past season and also does not have varsity girls basketball.

“Remaining in Class A is vital to offering athletic opportunities,” CMS athletic director Lakyn Traquair said. “Students do not attend our school for athletics, and we don’t have the athletes or the facilities to compete in AA.”

Aside from a small gymnasium, CMS has to rent other athletic facilities. The Executive Committee voted 14-2 to allow the school to remain in Class A for the next two-year cycle.

Palmetto Scholars Academy used the same basic rationale in its appeal to remain in Class A. The school is listed, after the multiplier, as 38th in enrollment among 41 Class AA schools. Many of the students that attend the school do so for academic reasons, and athletic opportunities are minimal. The school offers only six sports, and the only athletic facility is a gymnasium. PSA was unable to field a baseball team last spring and has not had a varsity girls basketball team for the last two years. The committee voted 13-0 in favor of the request to remain in Class A.

James Island and Lucy Beckham, currently assigned to Class AAAAA, have petitioned to move to AAAA. With the multiplier, James Island ranks 13th in enrollment, while Lucy Beckham is the smallest school in AAAAA. Both athletic programs have competed fairly well in Class AAAAA over the last two years with each school contending for state championships in several sports.

According to athletic director Jeremy Holland, James Island faces a capped enrollment of 1,600. James Island is a public charter school with 369 out-of-zone students, of which 101 are participating in athletics. It was noted that James Island finished sixth in the AAAAA Carlisle Cup standings, which ranks all schools in each classification based on athletic performance. The committee voted 15-1 to deny James Island’s appeal.

Lucy Beckham is currently a Division II program, and their projected enrollment figures are actually lower than six schools that will be classified in AAAA next year. With no other Class AAAA schools in the Tri-County area, Lucy Beckham would likely be placed in a region that includes three Beaufort County schools and Colleton County, increasing the amount of travel significantly. Bishop England currently is the only area school in that AAAA region but will compete in Class AAA in the next cycle.

Athletic director Frank Torcasio says the school would accept the travel requirements rather than compete at a numbers disadvantage. He cited the lower than usual varsity football players last season. The football roster was fewer than 40 players and played at least one game with fewer than 30 due to injuries.

“We are more than willing to travel in order to play schools that are more in line with our numbers,” he said.

The committee voted 14-2 to deny the request.

Another restaurant closes in James Island shopping center while 2 convenience stores expand

A James Island restaurant closed Dec. 28 after just six months in operation, with a note on the door citing “obscene” liquor-liability insurance costs as part of the reason — a rising expense that lawmakers have been attempting to tackle.

Charlotte’s on Maybank opened in August in James Island Shopping Center as a new concept from the owners of My Father’s Mustache, transforming the space where the English-style pub had operated for two years. The owners still run their longstanding My Father’s Mustache in Mount Pleasant.

The notice cited additional rising costs of doing business as the reason for the closure, including food and labor costs. The owners further thanked the staff and customers for their support as they closed the chapter on their suburban Charleston Island expansion.

The closure marks the second in the Harris Teeter-anchored shopping center in recent months. Maple Street Biscuit Co., a Cracker Barrel-owned chain, closed in October after seven years.

“We’re in discussions with potential tenants for both spaces,” said Christi Copenhaver, an associate at NAI Charleston, which is property’s leasing agency.

Gassing up

Two large gas station and convenience store chains are eyeing new Lowcountry locations.

Spinx, a Greenville-based chain, has submitted plans for a location at 514 Boone Hill Rd. in Summerville that would include 16 fuel pumps and a 5,300-square-foot C-store, according to a permitting application filed with the S.C. Department of Environmental Services. The site currently houses an abandoned carwash.

Meanwhile. Parker’s Kitchen filed plans with same state agency for a store in the Cainhoy area at 510 Everly St. near the planned Towne at Cooper River mixed-use development. The project calls for a 5,204-square-foot convenience store to be built with eight fuel pumps on 1.35 acres of densely wooded, undeveloped land.

Savannah-based Parker’s Kitchen has been making additional moves in the Lowcountry. A company affiliated with the retailer paid $1.65 million in December for a four-acre site at Highway 176 and Black Tom Road near the Nexton development in Berkeley County, according to public land records.

Game over

A struggling national retailer closing multiple locations in the Lowcountry as part of a national wave of shutdowns rolled out less than a week into the new year.

Signs posted at GameStop stores at 4950 Centre Point Drive near Tanger Outlets and in Moncks Corner announced their closures.

The company’s corporate office did not respond to multiple requests for comment.

The GameStop store at Mount Pleasant Towne Centre closed Dec. 5, according to a spokesperson for the property. Locations still listed on the company’s website include stores in West Ashley, Summerville and North Charleston.

A sweet return

Ben & Jerry’s is returning to the Isle of Palms, with a new shop slated to open this spring at Ocean Park Plaza, 1400 Palm Blvd. The brand closed its Ocean Boulevard location in 2022 after a nine-year run and has operated on the island since 2000.

Local franchise owner Andrew Lee previously ran the Isle of Palms store and operates locations in Freshfields Village on Kiawah Island and in Oyster Park in Mount Pleasant, will own and operate the new shop.

The larger, redesigned store will offer an expanded menu, including cookies, brownies, milkshakes and sundaes, along with ice cream, sorbets and non-dairy options. Founded in 1979, Vermont-based Ben & Jerry’s has eight locations in South Carolina.

Design arrival

A high-end furniture design store is coming to Upper King.

Design Within Reach, known as DWR, said it will open a showroom this spring at 423 King St., a low-slung brick building formerly used by Explore Charleston and known for its bright blue awnings between Vanderhorst and Warren streets.

The 13,174-square-foot space will feature original and exclusive mid-century and modern designs for residential, hospitality and trade clients. DWR is a Herman Miller retailer and is part of MillerKnoll.

The building was sold by St. Matthews Lutheran Church to Chicco Associates LLC in April for $5.2 million, according to county records. The reuse of the property has been cleared city’s design review process. Plans include the removal of the awnings.

Final cut

The New York Butcher Shoppe has cut back to focus on its more established Daniel Island location.

The company announced on social media on Jan. 3 that it was shuttering its West Ashley store, a 1,250-square-foot space at 1300 Savannah Highway that was opened in February 2024 by franchise co-owner Hunter Bishop.

The shop offered cuts of beef, chicken, pork, veal and lamb, along with prepared dishes, sides, wine, local beer, cheeses, exotic sausages and international groceries.

The Daniel Island location is at 864 Island Park Drive.

Now headquartered in Greenville, New York Butcher Shoppe was founded in 1999 in Mount Pleasant and expanded by selling franchises. It has opened locations in 10 states, including 16 in South Carolina.

At The Pass

The Pass Panino and Provisions has opened across the bridge in Mount Pleasant.

The Italian deli, which still operates its downtown Charleston shop on St. Philip St., is now serving from its second location in Northcutt Plaza at 976 Houston Northcutt Blvd.

The new East Cooper spot offers stacked sandwiches, antipasti platters and a small provisions market stocked with Italian specialty items. Owner Anthony Marini had initially expected the location to open by mid-November.

More than 10 schools will appeal SCHSL class placement. Here’s what we know

Gray Collegiate, Brookland-Cayce, Dreher, James Island, South Florence and Beaufort are among the schools appealing to the S.C. High School League for their 2026-28 classification placement.

More than a dozen high schools in total are all asking to drop one classification, The State has learned, from what the SCHSL assigned them during the latest round of realignment.

Schools had until 1 p.m. Wednesday to inform the SCHSL if they wanted to appeal the classification they were put in for the next two school years.

Appeals will be heard by the SCHSL’s executive committee on Jan. 13-14. A second appeal, if necessary, would go before the league’s appellate panel on Jan. 15-16.

Gray Collegiate was in Class 4A in the most recent realignment, and in Class 2A before that. The War Eagles opened up a second campus in Irmo earlier this school year. They’re appealing their new placement in 5A.

James Island was in Class 5A Division II this year, but the classification isn’t splitting its top class this year. James Island was placed in 5A again and will make its case to drop to 4A.

Realignment happens in the state every two years and attempts to level the competitive playing field among schools. This year’s realignment formula is based on 45-day enrollment numbers from grades 9-11 and featured an out-of-zone multiplier for the second time. That multiplier took each student who lives outside the school’s assigned attendance zone and counted them as three for total enrollment purposes.

South Florence and West Florence high schools will make appeals, according to state athletics sources, that contend reporting errors were made in counting their out-of-zone students and in how new students were counted from a merger with Florence School District 4 (Timmonsville).

Lowcountry schools Beaufort and Hilton Head Island are appealing their placement in 4A and want to be in 3A. Factoring in enrollment and the multiplier, the two schools are the 40th and 41st schools among the 42 assigned to 4A.

Brookland-Cayce, the 39th-largest school in 4A, is expected to appeal to move to the 3A. Dreher (25th in 4A) also is appealing to move to Class 3A.

During this year’s realignment, it also was decided that Class A (league’s smallest classification) would have the most teams in it, between 62 and 74 schools, with the chance of being split for sports that have more than 45 participating schools. Other classifications would be between 36 and 44 schools.

Roper St. Francis requests tree removal for new James Island facility

JAMES ISLAND, S.C. (WCSC) — Roper St. Francis Healthcare applied for a variance request to remove two grand oak trees to make space for an 11,000 square foot James Island emergency department, but some residents are pushing against the variance request ahead of the Board of Zoning Appeals hearing.Located at 832 Folly Road, the applicant says a free-standing emergency department with both a patient entrance and a separate ambulance entrance isn’t feasible without removing the trees. The new facility would provide emergency ...

JAMES ISLAND, S.C. (WCSC) — Roper St. Francis Healthcare applied for a variance request to remove two grand oak trees to make space for an 11,000 square foot James Island emergency department, but some residents are pushing against the variance request ahead of the Board of Zoning Appeals hearing.

Located at 832 Folly Road, the applicant says a free-standing emergency department with both a patient entrance and a separate ambulance entrance isn’t feasible without removing the trees. The new facility would provide emergency and imaging services to the barrier island. The residents, however, still believe the trees should be protected, and the location isn’t ideal.

Pamela Dennis Paxton has lived on James Island for 40 years and says while she welcomes a new healthcare facility, she wishes the trees could stay.

“I realize that development is a good thing and progress is a good thing, but I also feel like we have a unique place where we live,” Paxton says. “And the trees and the water and the marsh are all part of that ambiance. And without them, we wouldn’t be Charleston. I really feel like that all of the environment should be taken into account when any developer is considering developing something.”

In the letter of intent, Roper St. Francis Healthcare says that while they do preserve as many grand trees as possible and remove only those that make the project feasible, the variance approval is essential to ensure they can continue providing care.

Charles Fletcher is the vice president of real estate, construction and support services with Roper St. Francis Healthcare and says they looked at various locations, but the 832 Folly Road site is the best for their future plans of expanding further throughout the Lowcountry and eventually moving Roper Hospital in 2029.

“We think this is a good spot as we look at our long-term strategic plan of optimizing our footprint,” Fletcher says. “We know we get a lot of residents from James Island who get a lot of their emergency services and imaging services and things like that at Downtown Roper and we really want to make sure that we provide a more convenient access point for them.”

The tree care organization Natural Directions assessed the trees and rated them both a ‘B,’ meaning they only have minor defects and may be a species that is somewhat prone to health or structural problems.

The entire site is the former location of Wild Blue Ropes Adventure Park and is 1.84 acres in size and contains 21 grand trees in total. Roper St. Francis Healthcare says 17 existing grand trees would remain on-site to still match the existing character of James Island.

“We’ve gone through a lot of different iterations of the campus of the property to make sure that we preserve as many trees as we can,” Fletcher says. “We did put the building slightly in so we could reserve some of the larger trees.”

Roper St. Francis Healthcare also says they met with local property owners and received several letters of support ahead of the hearing.

The Board of Zoning Appeals must approve the variance request for the trees to be removed and also have the option to give specific conditions.

“On James Island, we are a wonderful group of people who are very serious about our trees,” Paxton says. “If they keep on doing this without our permission and we don’t like it, we won’t forget it.”

The Town of James Island Board of Zoning Appeals hearing is on Dec. 16 at 5 p.m.
