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

You don't have to be a graduate from The Citadel, the Military College of South Carolina near Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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 Wild Dunes, 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.

Wild Dunes Resort Honored in NGF/Players 1st’s 2026 GolfersVoice Awards

Premier Charleston luxury resort praised for exemplary course conditions.

Isle of Palms, S.C. Wild Dunes Resort – a Destination by Hyatt luxury golf resort set on Isle of Palms, South Carolina, has been honored in the 2026 GolfersVoice Awards presented by the National Golf Foundation (NGF) and Players 1st. The famed resort with two classic Lowcountry Tom Fazio-designed golf courses was singled out in the Course Conditions for Top Premium Courses based on outstanding customer satisfaction and loyalty scores received from their customer surveys.

GolfersVoice is a customer experience platform used by golf facilities to collect survey feedback from golfers and evaluate the associated data against benchmarks of similarly priced properties. The 2026 GolfersVoice Awards celebrate public and resort facilities with the highest customer-supplied scores on four key categories: Loyalty/Net Promoter Score, Course Conditions, Food & Beverage, and Staff/Customer Service.

“It’s an honor to be included among the winners in the 2026 GolfersVoice Awards, especially given that the award is in the category for Course Conditions and it’s decided by our customers who could spend their time and golfing dollars anywhere,” said Jeff Minton Wild Dunes Resort’s Director of Golf. “Our Superintendent Scott Ferguson and his team do a fabulous job of keeping both the Links and the newly renovated Harbor Course in tournament condition day-in and day-out. This award is tribute to their talent and hard work.”

Recognized as one of the top 10 resorts in the South by Conde Nast Traveler, Wild Dunes Resort and its partners have invested more than $150 million in property renovations since 2021. These investments include the debut of the Sweetgrass Inn, a stunning 153-room hotel featuring a 10,000-square-foot state-of-the-art spa, 30,000 square feet of meeting and event space, a 3,000-square-foot rooftop bar, and sprawling pool deck. Wild Dunes Resort expanded its sports offerings earlier in 2025 with the addition of two new tennis courts and six pickleball courts, catering to the growing demand and popularity of the sport.

“Traditional Top 100 rankings have their place, but golf facilities deserve a ranking and recognition podium for delivering exceptional customer experiences as well,” said NGF President and CEO Greg Nathan. “Many courses were operating at near capacity levels in 2025 and still delivered an experience that prompted their golfers to voice their satisfaction and loyalty at the highest levels.”

For golf facilities earning 2026 awards, the data shows a commitment to delivering very welcoming, customer-first experiences for guests booking rounds on their courses. GolfersVoice allows golf course operators to evaluate ongoing satisfaction at their facility, enables MCOs to compare results across a portfolio of co. es, and helps management create programs, services and promotions based on the results. Participating courses can seamlessly integrate GolfersVoice with their current POS/Tee Sheet software, receive real-time alerts on detractor customers, track their customer wallet share, and use built-in AI tools to summarize answers from verbatim and custom questions.

Notably, Wild Dunes’ Harbor Course recently reopened after a $9.5 million renovation project. The Fazio Design team, Heritage Links Golf Course Construction, Troon Golf, and the Wild Dunes Resort Golf Course Agronomy team collaborated to rebuild and expand all of the Harbor’s 18 greens to improve the playability, variety, and unique challenge of each golf hole. Several of the course’s bunkers have been reshaped and moved to accommodate modern driving distances and playing areas have been expanded in several locations to enhance playability and strategy.

All of the Harbor Course’s tee boxes have been rebuilt, leveled and, in some cases, expanded while the irrigation system has been replaced to help optimize turf conditions and water usage. Holes nearest the intercoastal waterway that runs alongside the course were raised several feet to curb flood risk and multiple golf cart bridges have also been restored.

Wild Dunes delivers one of the most complete coastal golf destinations in the region, with two award-winning golf courses, a private beach club, alluring pool spaces, ample nature trails, tennis and paddle amenities, spa and meeting services, first-rate cuisine, and activities for the entire family.
