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

You don't have to be a graduate from Dixie Technical College near St. George, 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 St. George, 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 St. George, 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 St. George, 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 St. George, 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 St. George, 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 St. George, 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 St. George, 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 St. George, 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 St. George, 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.

From jail cells to exam rooms: St. George facility transformed into health clinic

DORCHESTER COUNTY, S.C. (WCIV) — A building that once served as a women’s detention center in St. George is now set to serve a very different purpose – healthcare.

Dorchester County leaders and The Medical University of South Carolina Health cut the ribbon on a new primary care facility Monday morning, unveiling a renovated space that converts former jail cells into exam rooms. The transformation is part of a broader effort to expand healthcare access in rural Dorchester County and reduce the need for residents to travel long distances for basic medical care.

“When you walk in there today, you see a number of exam rooms. When they began this process, they were cells — now they’re exam rooms," said David Chinnis, the chairman of the Dorchester County Council. "It’s an incredible transformation."

County leaders say expanding healthcare options in western Dorchester County has been a long-term priority. For years, many residents in St. George and surrounding communities have had to drive outside the area to see a doctor.

“Folks were driving to North Charleston, they were driving to Orangeburg for healthcare,” Chinnis said, adding that the county initially tried to recruit emergency care providers to the area but received “zero feedback” through formal requests for proposals.

The newly renovated, 6,300-square-foot facility includes seven exam rooms and will offer primary care services such as wellness visits, chronic condition management, telehealth appointments and occupational health services.

MUSC leaders say bringing those services closer to home can make a significant difference for rural patients.

“When you need health care, you need it right then, and sometimes that travel makes it really, really hard to get timely care,” said Dr. Alka Kohli, chief medical officer for MUSC Physicians. “Having something in your own community allows us to provide that right at home.”

Kohli said the clinic is focused not only on treating illness, but also on prevention — helping patients manage their health before small issues become major problems.

“In addition to primary care, we have the ability [for] annual well checks and telehealth chronic care management and occupational health,” Kohli said.

County leaders say the project came together through a combination of federal and local funding. Chinnis said the county used approximately $2.5 million in American Rescue Plan Act funds, along with a $1 million USDA grant, to renovate the building rather than construct a new one. Additional state and federal funding will help outfit the facility and support future phases, including expanded imaging services.

Leaders described the clinic as part of a broader regional investment in healthcare infrastructure — not just for St. George, but for surrounding communities as well.

“It’s a Dorchester County project, but it is a regional healthcare facility that’s going to help folks in the entire region,” Chinnis said.

The clinic is expected to open to patients on March 2, 2026.

Dorchester County facility converts former detention center into primary, occupational health clinic

ST. GEORGE, S.C. (WCSC) — Dorchester County marked the opening of a new health care facility in St. George Monday, converting a former women’s detention center into a more than 6,300-square-foot health clinic.

Agencies that teamed up to make the clinic happen held a ribbon-cutting ceremony for the facility that offers primary and occupational health services to residents of the small rural community and the surrounding region.

The building, which previously housed a women’s detention center, now contains seven exam rooms.

“It’s an incredible transformation,” David Chinnis, Dorchester County council chairman, said.

Alka Kohli, chief medical officer for MUSC Physicians, said the change carries significance beyond the physical space.

“To see those doors and to see those rooms where we will now provide care, is such a difference from what it was,” Kohli said.

Three organizations will operate from the location: MUSC Health, the South Carolina Department of Behavioral Health and Developmental Disabilities and the Dorchester Drug and Alcohol Commission.

The clinic will offer by-appointment, in-person and virtual visits for annual wellness physicals, vaccinations, nutritional and dietary support, sick and injury visits, chronic condition management, lab testing and more.

Chinnis said the facility is intended to keep residents from traveling long distances for care.

“They’re not driving to the north area to the doctor’s office. They can stay here in St. George and it doesn’t take an hour to get there,” Chinnis said.

Kohli said having care providers embedded in the community is central to the facility’s mission.

“It becomes much more meaningful when you have care providers that live in the community, because it is also about building trust in healthcare. When you come in and you see someone who lives in your community that is now your healthcare provider and is helping you put together the pieces, that takes healthcare to a whole different level,” Kohli said.

The clinic was made possible through a $1 million USDA grant and approximately $2.5 million in ARPA funding. Additional support came from nearly $200,000 from the Southeast Crescent Region Commission and just over $700,000 from Sen. Lindsey Graham, designated for a mobile MRI unit and X-ray equipment.

Strategic planning for the facility began in 2017. A second phase of the project is expected to be completed in 2027.

The clinic is scheduled to open on March 2.
