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

You don't have to be a graduate from Haut Gap Middle School near Kiawah 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 Kiawah 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 Kiawah 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 Kiawah 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 Kiawah 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 Kiawah 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 Kiawah 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 Kiawah 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.

The South Carolina House of Representatives slipped funding for a $32 million legal settlement into the 2026-2027 budget – despite failing to even discuss the controversial payout during the committee process.

The appropriation would end decades of litigation, appeals, and mediation over on Kiawah Island – an exclusive barrier island located approximately 25 miles southwest of Charleston, S.C.

The settlement involves the Conservancy of the Sea Islands, the Town of Kiawah Island, the Kiawah Island Community Association, Kiawah Partners and the State of South Carolina. If it makes its way into the final version of the spending plan, it would compensate developers for lost income from a land parcel that extends from Beachwalker Park to the Kiawah River after the state compelled developers not to construct housing there due to ecological concerns.

Under the agreement, the land would be placed into a conservation easement held by the Conservancy of the Sea Islands. This easement would eliminate future residential development rights and preserve the land in its natural state. The spit is one of the few remaining undeveloped native habitats for multiple Palmetto State native species, including sea turtles and migratory birds.

If the deal goes into effect, the Town of Kiawah Island would acquire ownership of Beachwalker Park ensuring public access to the beach, while the state would take ownership of the remaining land, with portions potentially designated as a Heritage Trust Preserve under the auspices of the S.C. Department of Natural Resources (SCDNR).

Skeptics of the appropriation agree the land should be preserved, but insist developers were forewarned that their speculative investments would be valueless at the time they decided to buy the land, and are therefore unlikely to prevail in legal challenges demanding the state compensate them for lost potential revenue.

Opponents of the settlement argued during the budget debate on Tuesday evening (March 10, 2026) that regardless of the validity of the deal, it is unfair to ask lawmakers to approve a multi-million dollar expenditure that wasn’t discussed as the budget made its way through the committee process.

S.C. Freedom Caucus’ chairman Jordan Pace protested the line item – opposition unexpectedly buttressed by representative Gil Gatch, who pointed out during the floor debate that the developers have already struck out repeatedly in state courts.

Gatch, a lawyer-legislator, also claimed federal case law in support of the plaintiff’s case was shaky at best.

“Why would the attorney general settle with the developers in Kiawah when the developers don’t have a legal theory to win,” Gatch asked, questioning why attorney general Alan Wilson would “give a handout to the developers.”

Wilson’s office declined to comment on the settlement citing it’s inability to speak about pending litigation.

“I wanted to amend (the budget) to take ninety days to do due diligence to make sure that what we’re doing makes sense,” state representative Joe White told FITSNews in an interview conducted the day after the House approved funding for the settlement in the budget. “The ramifications for the future of South Carolina are that once you settle one of these out of court without litigating, every developer in South Carolina can claim ‘you cheated me out of something, and now the state owes me something.'”

White warned the case “could alter for the future what we can defend in South Carolina.”

After having conversations with attorneys familiar with this type of litigation, White said he wanted more due diligence done on the recommendation from the attorney general’s office that the state settle the case.

“I talked to administrative law judges here in South Carolina that said we would win this lawsuit if we pushed it forward,” White said.

White likened the deal to the General Assembly’s decision to ramrod Scout Motor’s economic development deal, which was also was also expeditiously funded with astonishingly little public input or oversight.

“This is similar to the Scout Motor deal which I voted against three years ago,” he said. “We did no due diligence on that, we did no due diligence on this. It never went to subcommittee or committee in the House. It just appeared in the budget, and most of the legislators knew nothing about it until last night.”

White lamented their approval of the expenditure, but added the process has run its course in the House.

“We approved it,” he said. “It’s done.”

Opponents of the appropriation must now rely on the S.C. Senate to remove it from the state’s spending plan, as governor Henry McMaster – who included the expenditure in his executive budget – is obviously not going to veto the money in the event it makes it to his desk.
