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

You don't have to be a graduate from Antares English Language Center near Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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 Summers Corner, 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.

A long-anticipated Publix supermarket is finally turning dirt in Summerville’s Summers Corner development at 1612 Beech Hill Road.

First announced in January, the project generated new buzz Nov. 23 after the neighborhood posted the news on its Facebook page that the site is finally under construction. The post garnering 900 likes and more than 200 shares in just days.

A spokesperson for the Lakeland, Fla.-based grocer said the store expects to hire about 140 employees.

The Publix will be the anchor tenant for the new retail center, with plans calling for a 50,800-square-foot supermarket and eight 1,200-square-foot suites.

At full buildout, Summers Corner is expected to exceed 7,500 homes.

On a related note, Publix will mark its return to Daniel Island next Wednesday at 7 a.m., after a nearly year-long absence that left DI without its own full-service grocery store. The chain closed its original location at 162 Seven Farms Road in late 2024 and rebuilt a larger supermarket in its place in less than 12 months.

Goodbye, Ruby Tuesday

Ruby Tuesday has pulled out of North Charleston leaving the chain with just one Lowcountry restaurant.

A sign on the door at 7400 Northside Drive directs customers to the West Ashley location at 1953 Savannah Highway. Company representatives did not respond to a request for comment.

Maryville, Tenn.-based Ruby Tuesday is owned NRD Capital, a private equity firm. The casual dining closed its Summerville location earlier this year.

Completely floored

Floor & Decor has opened its long-awaited warehouse store and design center at 1155 Holliday Farms Blvd. next to The Home Depot in Highway 17 in Mount Pleasant.

The new store employs about 50 workers and is led by Matthew Peiffer, whose title is chief executive merchant.

The Atlanta-based retailer specializes in flooring for homeowners and professionals. It operates more than 250 warehouse-style outlets nationwide, including South Carolina stores in North Charleston, Columbia, Greenville and Murrells Inlet.

A ribbon cutting is set for Dec. 2 at the Mount Pleasant store, featuring giveaways including a $5,000 floor makeover and 2026 Charleston Southern University football season tickets.

Palm pleasant

Gwynn’s of Mount Pleasant, a mainstay luxury boutique that plans to open a second location in downtown Charleston, has unveiled five holiday window displays with a 1967-era Palm Springs, Calif. theme.

The department store’s inspiration this year is “A Holiday on Holiday” concept, capturing “the golden glow of a retro holiday.”

The mid-century-inspired vignettes include glittering garments, glowing pink flamingos and rotating disco balls that channel holiday department-store spectacles in major cities.

Market to market

A food truck is opening a brick-and-mortar downtown.

Luther’s Market & Eatery, known for its pastas, casseroles and sauces, will take over 227 Rutledge Ave., formerly home to Pinot & Provisions, which closed Oct. 31.

The new tenant is expected to open in January and will offer global comfort foods from the mother-and-son duo of Kiki Luthringshausen and Hudson Luthringshausen. Until then, their pastas and sauces are currently available via their food truck and at Corner Store, a grab-and-go market that opened this summer in West Ashley in the former home of Taco Bartina.

3rd First Watch

First Watch, a breakfast, brunch and lunch spot, will open its third Lowcountry restaurant on Dec. 15 at the Market Place at Carnes Crossroads in Goose Creek. Founded in 1983, the Florida-based chain operates more than 620 restaurants in 32 states, including locations in Summerville, North Charleston and Mount Pleasant.

Mall market

The Joy Market has returned to Citadel Mall in West Ashley with a rotating lineup of local vendors selling holiday goods. It runs Nov. 26–Dec. 30 from 11 a.m. to 7 p.m., with gift-wrapping available.

Very neighborly

Park Circle home-decor shop Neighborly will celebrate its one-year anniversary with a holiday market on Small Business Saturday, Nov. 29 with live music, food trucks and 18 vendors.

The event will run from noon to 5 p.m.

Let it snow

Tanger Outlets in North Charleston will bring winter magic to shoppers with “snow flurries” every Saturday from noon to 3 p.m. from Nov. 29 until Dec. 20 near the shopping center’s 40-foot-tall Christmas tree.

Kids can also leave messages for Santa via the mall’s “Santa Hotline.”

No. 1 pick

A national indoor pickleball club operator that's opening in North Charleston next month has announced a partnership with a fashion brand created for the sport's “court-to-cocktail” lifestyle.

SUMMERVILLE, S.C. (WCSC) — The Summers Corner community hosted its 4th Annual Winter Festival – Whoville edition, bringing families and friends out for festive fun and supporting local businesses for the holidays.

This year’s brought Grinches of all ages and even Cindy Lou Who singing Christmas songs. The festival included a petting zoo, free Christmas train rides and snow for family entertainment.

Vendors said shopping locally has a far greater impact than what people may see. For some business owners, the community support makes a significant difference in their lives.

“Being able to come to these events, we do this full-time. I was able to cover my kids’ entire Christmas just by coming to vendor events. So, I’m very thankful for all of our customers and everybody that supports us,” co-owner of The Scented Cactus Co. Kaylee Holmes said.

For Samantha Creech, owner of Southern Naturals, the support means even more during difficult times.

“My husband has stage four cancer. And so this is how we support our family. But you never know what somebody’s going through, and how supporting them and what that means to them,” Creech said.

Rebecca Stephenson, a resident and event organizer, emphasized the importance of community connection.

“These are your neighbors, these are people that share your parks, there are people that you wave by as you’re driving down the street and, you know, you’re supporting their livelihood, and their ability to raise their families, and pay their bills and in the same turn, you’re also getting some really cool gifts and really cool experiences that honestly, where else can you get that?” Stephenson said.

Local financial advisor Alwyn Coetzee sponsored this year’s Christmas train rides for families to enjoy and said that, for his family and being in the financial planning practice, it’s really important to give back to our community.

“It’s for a very brief moment where we can still enjoy this and the magic and Santa Claus and all the amazing stuff, and so that brings a lot of joy to my life to see everyone here,” Coetzee said.
