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. (WCSC) - Around 15,000 people have eaten their way around the Ladson Exchange Park over the weekend to enjoy the annual Black Food Truck Festival.

The festivities began this weekend with the “Rhythms & Booze” Opening Soiree at the International African American Museum and continued with the food trucks into the rest of the weekend.

The festival’s founder, Marcus Hammond, says between 45-50 vendors selling everything from seafood to desserts to apparel lined the park.

With the festival starting after the pandemic three and a half years ago, he says they’ve tried to bring the cultural ties between food, music and culture back year after year.

“The entertainment is top notch,” Hammond said. “We always find the best bands from the region, locally, around the area. People love the Kids’ Zone. They’re able to come out and have their kids with the Kids’ Zone. I mean, there’s just something for everybody. That’s the best part about it.”

Hammond says he wanted this tradition to be multi-generational so that anyone and everyone would keep coming back for the food, entertainment and more.

And aside from the daytime festivities, the festival has also hosted after parties, such as “Trappyoke” and “AfroChuck” for those who want to stay into the night.

“We really just wanted to celebrate the culture in a major, major way here in Charleston,” Hammond said. “Charleston is world-renowned for its hospitality and tourism and its cuisine, and Black people are a part of that. So, we want to celebrate that with the community and celebrate that with the world.”

In the future, Hammond wants to continue bringing this festival back to the Exchange Park and start a new culinary bootcamp for kids. He says he’s welcome to anyone reaching out to help make that goal a reality.

Mexican market and restaurant with scratch-made tortillas to open 3rd Charleston-area location

LADSON — The owners of a popular restaurant and market with locations in West Ashley and North Charleston are opening a new business, their fifth in five years.

El Molino Supermarket, known for its tacos, tortas and tortillas, will open at 113 College Park Road in Ladson, previously home to a gym named Fitness Fusion. The new destination is slated to open in September 2025.

El Molino is owned by Jaime Tinoco and Pamela Sierra, who hails from Guadalajara, Mexico. The pair debuted their West Ashley original in 2020 before opening a larger location at 5900 Rivers Ave. in 2023. Last year, they unveiled two new neighboring businesses, Kooben Café Mexicano and La Tapatia, in Hanahan.

The need for a third El Molino came from a desire to cater to the growing population in Summerville, Sierra said.

"A lot of people, they say (North Charleston is) too far away," Sierra said. "It's going to be closer to them."

El Molino Ladson's offering will mirror that of the other two locations, meaning patrons can expect a scratch kitchen; selection of Mexican pantry items, produce and beverages; bakery; and tortilleria, where the staff will produce house-made tortillas in bulk. The taqueria inside the new outpost will lean more heavily into coastal Mexican cooking than North Charleston and West Ashley, with seafood-forward items like ceviche and aguachile planned for the menu.
