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

You don't have to be a graduate from Charleston Collegiate School near Johns Island, 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 Johns Island, 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.

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 Johns Island, 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.

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 Johns Island, 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 Johns Island, 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 Johns Island, 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 Johns Island, 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 Johns Island, 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.

JOHNS ISLAND, S.C. (WCSC) - The City of Charleston is seeking public input on plans for Johns Island’s first-ever recreation and aquatic center.

Council members say this is a long-awaited project that will bring major amenities to one of the region’s fastest-growing communities.

The proposed design includes two swimming pools, an indoor gymnasium with two basketball courts, fitness rooms, classrooms, multipurpose spaces, a catering kitchen, outdoor pickleball and basketball courts and an inclusive playground and splash pad.

The project, located off Maybank Highway, will be funded by the City’s $70 million parks bond referendum that was overwhelmingly approved by voters in 2023.

City officials say the preliminary design incorporates nearly all the amenities that residents have requested so far. Their primary interest in seeking feedback lies in the number of multipurpose rooms, noting the island’s limited meeting spaces.

Charleston District 3 Councilmember Jim McBride says the new center will provide convenient, much-needed recreation opportunities for residents who currently must travel long distances to access similar facilities.

“These kinds of things are needed public services,” McBride says. “When they’re on the island, people don’t have to drive a long way to get that. Right now, if someone wants to use a pool, they have to drive 20 or 30 minutes away and that’s a barrier for some people.”

City leaders believe expanding recreational options on Johns Island will help reduce traffic congestion by giving families more reasons to stay on the island for activities.

The public feedback meeting will be held Monday from 5:30 p.m. to 7 p.m. at Haut Gap Middle School, where city officials and the design team will present preliminary plans for the 50,000-square-foot facility.

Construction of the recreation and aquatic facility is expected to begin within the next two years.

JAMES ISLAND — On Nov. 4, residents will choose two new representatives to join the Town Council.

After voters passed a referendum in 2023 that expanded James Island Town Council’s governing body from four members to six, the time to add those new council members has come. The four residents who are running to fill the two seats said they are committed to serving the residents but differ slightly in how they plan to do so.

‘We are one James Island’

Julia Drayton-Crumblin has lived on the island her whole life. She’s opening a childcare center for kids ages six months to 3 years old in January and runs a rental property business with her sister.

Her platform revolves around town connectivity and giving back, from exploring ways to keep housing affordable to encouraging more neighborhood connections. Drayton-Crumblin said she’s considering starting a community garden.

“I do believe we are one James Island, and I want all of us to remember that so we can still become successful and thrive as a community,” Drayton-Crumblin said.

While she's still exploring specific approaches to affordable housing, Drayton-Crumblin said she wants to ensure there is smart development on the island. She’s open to visiting other municipalities to see what they’re doing to keep housing accessible for residents.

Being a voice for residents

Stanley Kozikowski is retired, but said when you live on James Island, you never really retire.

“There’s too many people to help,” he said.

Kozikowski spends a lot of time volunteering with various nonprofits on the island and enjoys helping his neighbors out. He hopes to continue helping the community on Town Council, mostly by working to slow down development.

There are multiple reasons for pacing the rate of development, he said. The island needs infrastructure to catch up with the growth. Kozikowski added he also wants to save more green space for wildlife.

He’s committed to being a voice for residents when coordinating with neighboring municipalities and Charleston County, he said.

Focusing on the residents

Kristen Meredith Poston, a server and bartender, said her job has many similarities to a community leader.

Poston has served a term on the James Island Public Service District Commission. She said that role has helped her learn to listen to people, whether they’re talking about issues or something they’re excited about.

Poston hopes to continue her focus on residents if she’s elected to Town Council. While she would be an elected official, she would be working for the residents and ensuring their voices are heard, she said.

She added that while the Charleston area is becoming more popular and more people are moving here, she wants to curb development and preserve James Island’s character. Poston said she’d want to keep the island calm and as far away from over-development as possible.

Town Council is ‘a lifelong calling’

Michael O’Shaughnessy Williams said when he moved to James Island seven years ago, he fell in love with the town and knew he never wanted to leave. He also realized this is where he’d want to run for office to help the community, describing it as a lifelong calling.

Williams’ top priority if elected is land preservation and pushing back against development. The marsh, creeks and tree canopy help make James Island special, and he wants to protect that.

The town needs leaders who have the determination to push back against the city of Charleston and the county when it comes to zoning for future development, Williams said. He added that he wants to work with both local governments because they all have jurisdiction on James Island and hopes collaboration will help solve issues residents have.
