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

You don't have to be a graduate from Southeastern College Charleston near Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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 Ladson, 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.

LADSON, S.C. (WCBD) – A small earthquake was recorded near Ladson late Sunday night.

The South Carolina Emergency Management Division said the United States Geological Survey confirmed a 1.7 magnitude earthquake struck 5.8 miles south-southwest of “Centerville” around 11:17 p.m.

The tremor was likely too small for anyone to notice.

The United States Geological Survey often records small earthquakes with Centerville pinned as a geographical location. People often ask us, where is Centerville?

If you search “Centerville, South Carolina” on Google, the results will show you a community in Anderson, South Carolina. But a Lowcountry destination does exist — or at least it did.

Officials with the United States Geological Survey previously told counton2.com that it uses a database called “Geonames” to automatically locate the town nearest an earthquake. That database, which is not a USGS-owned product, is what pulls Centerville as the location identifier.

They believe there was once a historical placename from the 1700s or 1800s.

“We locate thousands of earthquakes per year, and it is only a few that end up with a problem like this,” said Dr. Thomas Pratt, a research geophysicist and Central and Eastern Region Coordinator for the USGS Earthquake Hazards Program, when asked about the notification name.

While the community does not necessarily exist today, USGS said it is unlikely that the Geonames database would change the name because it’s such a rare occurrence.

So, where was Centerville?

The geography of that area includes portions of Summerville and Ladson in Dorchester County.

Roughly a year ago, historian Nic Butler, who hosts a weekly podcast called ‘Charleston Time Machine,’ reviewed documents to help us understand where Centerville might have come from.

Butler found no mention of the community in digitized newspapers from the 18th, 19th, or 20th centuries during his search. He said it is not referenced in the online index of the South Carolina Department of Archives and History, nor does the name appear on any maps of the Charleston-Summerville area until the early twentieth century.

Some success came when looking at the USGS topographical map of the Ravenel Quadrangle, which Dr. Butler said was surveyed in 1918 and published in 1920. Centerville is seen at the present intersection of Gahagan Road and Miles Jamison Road.

A look at the topography map from the 1920 publication shows two neighboring areas called Stallsville and Centerville.

Butler explained that the placename “Stallsville” refers to an extinct unincorporated village that was once clustered around the intersection of Bacons Bridge Road and Old Trolley Road.

There is a historical marker that shares a story of the Stall family settling and farming that area in the early 1800s. The two villages, Stallsville and Centerville, were likely divided at the time.

Counton2.com did reach out to Dorchester County Government for a records check in December 2024; however, at the time, they were unable to provide any details.

More than 10 earthquakes have been reported in the area since 2021. The largest was a 0.9 in March 2022, and the strongest was a 2.53 earthquake on July 24, 2023.

QUAKES IN CENTERVILLE

11/9/25 – 1.712/11/24 – 0.8112/7/24 – 2.0911/20/24 – 1.047/14/2024 – 2.531/18/23 – 1.389/2/22 – 1.456/15/22 – 1.06/27/22 – 1.23/28/22 – 0.911/9/21 – 1.58/27/21 – 1.718/21/21 – 1.753/16/20 – 2.4

Still, emergency management officials in South Carolina say there is no need to worry as earthquakes are common here; however, they encourage everyone in the state to be prepared and have an action plan should a large quake strike.

LADSON, S.C. (WCSC) - The Coastal Carolina Fair concluded its 68th year Sunday at Ladson Exchange Park, with organizers emphasizing the event’s charitable mission and family fun.

The fair featured 65 rides across 180 acres, along with classic games, food vendors and a petting zoo that welcomed a new baby donkey.

“Why we have the fair here is to give to charities in the local Tri-County area,” Coastal Carolina Fair President Fred Whittle said.

Robert Patterson, owner of Top Shelf Catering and Beverage and Special Ops Events, said sales were up double digits this year.

“Every time we win, the community wins,” Patterson said. “When we’re up in sales, that gives us more proceeds to be able to give to those local charities. So, it has been a huge success.”

But the fair isn’t about profit. The fair runs on volunteers who say they get paid in a different way.

“The joy on the faces of children is the thing that is my pay. And I’m not paid as a volunteer. But that certainly is a rewarding thing for us to see.” Whittle said.

The baby donkey was already out, greeting visitors on the final day.

“I came out and I saw feet. So I knew I had to step in and help her, and it’s a healthy little girl,” Charles Beam, owner of All American Petting Zoo, said.

Local vendors said the fair provides both business opportunities and community connections.

“I make a living, so I keep coming back, plus all the directors here, they’re beautiful people,” John Koutoufaris, owner of John Greek Food Concessions, said.

While today was the final day of the fair, several people said this is proof that when a community comes together for fun, everyone wins, especially the local charities helping those in need with the donations.
