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

You don't have to be a graduate from University School of the Lowcountry near Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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 Mount Pleasant, 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.

The Fresh Market made its greater Charleston, S.C.-area debut on May 3, with the grand opening of a new store, in Mount Pleasant, S.C. This brings the total number of stores for the specialty grocer to 172.

The Mount Pleasant location is The Fresh Market’s latest in a trio of recent new openings. Two locations in Wethersfield, Conn., and Jensen Beach, Fla., both debuted exactly one week earlier. The three stores cap a period of growth for the company, which has opened 11 grocery retail locations and the new Spirits & Wine concept in the past six months.

The new 25,000-square-foot Mount Pleasant store is stocked with a carefully curated selection of high-quality meats and seafood, along with fresh produce, local finds and a unique collection of international products. The Fresh Market also boasts a broad selection of restaurant-quality prepared meals and sides, and ready-to-cook, ready-to-heat options.

“We are extremely pleased with the response to our new store,” said The Fresh Market CEO Brian Johnson. “We have a great team that is excited to bring our brand of impeccable hospitality to the town of Mount Pleasant.”

On opening day, customers took part a myriad of The Fresh Market opening traditions, including a bread-breaking ceremony and the cracking of an 80-pound wheel of parmesan cheese. Additionally, the first 120 customers received a free 4-inch potted orchid, and the first 500 guests were given a The Fresh Market Mount Pleasant reusable grocery bag.

The Fresh Market also continued its commitment to supporting a local food bank with every new store launch. The team kicked off a partnership with the Lowcountry Food Bank and presented a $2,000 donation to the organization.

Greensboro, N.C.-based The Fresh Market currently operates more than 170 grocery stores in 22 states and one Spirits & Wine store. The grocer is No. 71 on The PG 100, Progressive Grocer’s 2024 list of the top food and consumables retailers in North America. The Fresh Market was also one of the recipients of PG’s inaugural Innovation Awards in the Mid-Tier (50-299 stores) category. The award was presented at the publication’s 2024 GroceryTech event in Dallas.

MOUNT PLEASANT — A fast-casual Greek dining concept is returning to the Charleston region.

Taziki’s Mediterranean Café, a Birmingham, Ala.-based franchise serving made-to-order dishes, is set to open in early summer at in the REI-anchored Indigo Square shopping center in Mount Pleasant along Highway 17.

The 1,688-square-foot café will feature a large community table, outdoor patio seating and pickup shelves for to-go orders. Around two dozen employees will be hired for the new location. Stephen Sommers is the operating partner.

The restaurant will be the third time that Taziki’s has a Charleston presence.

The chain's first location in South Carolina at 306 King St. operated for eight years from 2011 to 2019, closing after its building was among several properties sold as part of a $24.5 million real estate deal.

Franchisees then opened a second Taziki’s in Mount Pleasant at 320 W. Coleman Blvd. in 2014, taking over the space that housed longtime restaurant Locklear's, which moved out of the location because of rising rent costs. Taziki’s had an eight-year run before closing for good in November 2022.

Nationwide, the chain has grown to more than 100 restaurants in 18 states over the past 27 years.

The new East Cooper location will be the company’s fourth in South Carolina. The other restaurants are in Greenville, Columbia and Simpsonville.

MOUNT PLEASANT – A splash pad, exercise equipment and elements that nod to long-gone landmarks are features of the expanded Memorial Waterfront Park under the Arthur Ravenel Jr. Bridge.

Motorists can catch a glimpse of the park's basketball and pickleball courts when coming off the bridge into Mount Pleasant. For roughly two years, crews with Hill Construction worked to turn the swath of dirt and grass beneath the bridge into an extension of the "crown jewel of Mount Pleasant."

The area beneath the Ravenel Bridge on Harry Hallman Jr. Boulevard remained an undeveloped grass lot for years, primarily used for overflow parking during events like the Sweetgrass Basket Festival or the Blessing of the Fleet.

But on June 2, the park was almost finished as Special Projects Manager Steve Gergick walked through, chatting with construction crew members who fiddled with equipment and sealed light fixtures.

Save for a small field in the center blocked off with orange fencing to protect the sprouting new grass and four basketball backboards with no nets, the latest iteration of Memorial Waterfront Park appeared ready to welcome visitors.

After a series of permitting and construction delays, the $6.75 million expansion officially opened on June 4. Originally scheduled to open in 2024, the park expansion across from the pier and the Sweetgrass Cultural Arts Pavilion, will open the same day.

"We've been trying to cross that finish line for a long time," said Gergick. "We didn't want to open it up before it's in good condition for the public."

A piece of the Grace Memorial Bridge is on display at the front of the park, accompanied by a historical marker, a remnant of the Ravenel Bridge's predecessor that connected Mount Pleasant to Charleston. The Grace Memorial Bridge, along with the Pearman Bridge, were demolished in 2005.

MOUNT PLEASANT, S.C. (WCSC) - Mount Pleasant town leaders will consider a change to an ordinance that would allow owners of a former restaurant to build a hotel in its place, a move the town’s mayor is against.

The town’s planning commission has recommended amending the Seaside Farms Planned Development District Ordinance to allow for a small boutique-style hotel to be built. That hotel, which would be limited to no more than 25 rooms, would be built at the site of the former Yamato Steakhouse on Riviera Drive.

The owners of the former restaurant hope to build the new hotel within the Neighborhood Retail and Office Tracts on a 2.4-acre parcel of land near the Isle of Palms Connector.

But Mayor Will Haynie says he does not believe many of the town council members are on board with the change based on conversations he has had with them. He says the neighborhood was initially designed to have grocery stores, restaurants, pharmacies, and retail all in one place to reduce driving traffic.

Adding a hotel there, he believes, would add to beach traffic.

“I just don’t see how putting something that is just for transient use is within the keeping of what the neighbors want and by far from what I’ve heard of seaside neighbors is they don’t want another hotel in there, not every single one, but by far the majority of them feel that way,” Haynie says.

One business owner who declined to speak on camera said with the Harris Teeter next to the potential development site going out of business, having a hotel may help bring in business from visitors.

Haynie said he would like to see that space turned into something people who live in that neighborhood can use.

“As Mount Pleasant has grown, one reason this was put up there was to be a place where when you get home, if you have to commute, maybe you can work from home, that you don’t have to leave and contribute to the traffic on all the major arteries,” he says. “And so I look at something like this through that intent and that was the original intent of that whole neighborhood, and I’d like to see it stay that way.”

Haynie said if the proposal gets voted down, the property owners must wait a year before they can reapply or that can be waived if they come back with a different plan.

If someone buys the property and uses the zoning as is, town council does not have to vote on everything that goes on there.

This proposal is unrelated to the Harris Teeter property. There are no plans to convert that space into housing or a hotel, and it currently has two strong leasing prospects, town leaders say.
