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

You don't have to be a graduate from LaTrice D Ferguson Healthcare Institute near Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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 Walterboro, 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.

Both dine-in and drive-thru service will be available.

The Walterboro restaurant follows the successful December 2024 opening of Krystal’s Orangeburg location in partnership with Charlamagne Tha God, and marks the brand’s continued expansion across the state. It joins existing South Carolina restaurants in North Augusta, Aiken, Gaffney and Orangeburg.

“As we grow in South Carolina, our focus is on creating meaningful connections with our guests and our team,” said Amanda Hyde, Senior Vice President of Operations for Krystal. “That means more than great food. It’s about greeting guests by name, handing over every order with care and creating an environment where team members feel empowered to deliver true hospitality.”

Krystal is hosting an in-person hiring event on Wednesday, June 11, from 11 a.m. to 5 p.m. at the new Walterboro location. The team aims to hire 40 new employees for all shifts.

Applicants should bring a valid ID and Social Security number. No prior experience is required – just a passion for great food and service.

Founded in 1932, Krystal has remained a Southern staple for more than 90 years, evolving with the times while staying rooted in warm hospitality and craveable, familiar flavors.

Headquartered in Atlanta, Georgia, Krystal Restaurants LLC is the original quick-service restaurant chain in the South. Krystal hamburgers have been served fresh and hot off the grill on the iconic square bun since 1932. The company proudly sticks to the classics, but they’ve never been afraid to innovate. Krystal has expanded to 12 states with nearly 300 restaurants and continues to deliver a one-of-a-kind taste experience through unique menu items offered at a great price. In 2023, USA Today readers named Krystal the “Best Late-Night Fast Food,” and in 2022, research and consulting firm Technomic ranked Krystal as one of the “Most Craveable Burgers.”

Beaufort Memorial Oncology Specialists add Board-Certified Family Nurse Practitioner

OKATIE, S.C. – To better serve individuals diagnosed with cancer in southern Beaufort County, Beaufort Memorial has added a board-certified family nurse practitioner to the medical oncology team at Beaufort Memorial Oncology Specialists.

Lindsay Gamble, FNP-BC, will bring her diverse background in palliative and critical care and infusion therapy to the Beaufort Memorial cancer treatment team. At the New River Cancer Center in Okatie, she will see medical and hematology patients before, during and after treatment; manage chemotherapy infusions and education; recommend, facilitate and interpret laboratory testing; and order imaging.

“Lindsay will be an excellent addition to the team at Beaufort Memorial Oncology Specialists,” said Beaufort Memorial President and CEO Russell Baxley. “Her wide-ranging experience and personal connection to patients and their care will allow patients receiving cancer treatment at the practice to feel heard, valued and well cared for.”

Gamble’s commitment to patient-first, personalized cancer care developed over her years of nursing experience in Tennessee, California, Virginia and Louisiana, with her most recent experience in both emergency medicine and infusion therapy in Beaufort County. Her passion for the medical oncology field grew in intensity after supporting multiple family members through their cancer treatment journey – including her father.

Gamble graduated with a Master of Science in Nursing with a Family Nurse Practitioner concentration at the University of Memphis in Memphis, Tenn., in 2017. She’s bringing her knowledge and drive for compassionate cancer care to Beaufort Memorial from her most recent position at Palmetto Infusion Services in Okatie and is dedicated to providing high-quality care to patients receiving treatment for all types of cancer while exploring all of their options.

“I believe in listening, empathy and support, recognizing the profound impact of a cancer diagnosis on patients and their families,” Gamble said. “My mission is to provide not just care, but hope, dignity and resilience.”

At the New River Cancer Center, Gamble joins Drs. Eric Turner and Michael Porrazzo, oncology nurse navigator Catherine Healy, RN, BSN, and oncology social workers Kianna Brown, LMSW, and Samantha Bruns, LBSW.

Beaufort Memorial cancer programs focus on prevention, screening and treatment of a wide variety of cancers. Patients have access to medical oncology, radiation oncology, cancer surgeries and lab, imaging, infusion and breast health services at both the New River Cancer Center in Okatie, as well as the Keyserling Cancer Center in Beaufort.
