Being aware of common AC unit problems helps prevent breakdowns. Who wants to be stuck inside during a hot summer in Wadmalaw Island, SC without AC?

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 Wadmalaw 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 Wadmalaw 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 Wadmalaw 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 Wadmalaw 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 Wadmalaw 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 Wadmalaw 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 — A national homebuilder has reached the end of its appeals in state courts fighting for what it believes is its right to cancel sales contracts for any reason it wants.

That includes putting a customized house back on the market to sell to another buyer at a higher price.

A March 11 ruling by the S.C. Supreme Court culminates the five-year lawsuit against Charlotte-based Eastwood Homes filed by contracted buyers of nine homes within the builder’s Swygert’s Landing subdivision on Johns Island.

The case centered on a dispute between the buyers and builder after Eastwood canceled each of their contracts on the same day in June 2021, some shortly before the sales were to close. In return the buyers were given a refund of their deposits and $100 for “damages.”

Ever since, the purchasers have stood their ground against the homebuilder for breach of contract, arguing the language regarding cancellation was vague, unfair and one-sided.

Two state courts have since agreed. The Supreme Court has declined to intervene in those decisions.

“Eastwood has spent five years trying to convince a court, any court, that it should be able to cancel contracts on families days before closing and walk away with no consequences,” attorney Ross Appel, co-counsel for the purchasers, told The Post and Courier. “This issue is now settled. These are real contracts with real families and Eastwood is going to be held accountable."

Plaintiffs Chris and LaShonda Jones Rayborn were one month away from closing when they got the email on June 4, 2021 — a day Chris Rayborn said is burned into his memory.

“At the time, we were living in a townhouse and had already purchased all the furniture and everything,” he said.

They waited out years in the crammed space before inevitably buying another house on Johns Island.

Lou Galvinos and his wife, Kimberly, were in a similar spot. Four days before the Eastwood email arrived, the plaintiffs had sold their Kentucky house and put their belongings in storage. Because they had to move to Charleston for jobs, they ended up living in a nearby apartment for three years with their items in storage hoping the case would have resolved sooner.

But they and the other buyers stuck it out, filing individual lawsuits against Eastwood that later became one big play against the homebuilder.

“Our lawyers said it would be a very hard sell, but we didn’t think it would be because we were the ones who were wronged,” Galvinos said. “We signed the contract with them, asking about price increases and stuff like that. They said the price is guaranteed once you sign the contract … (because) they buy all the products right then.”

In June 2025, the S.C. Court of Appeals upheld an initial 2024 ruling by Charleston County Master-in-Equity Mikell Scarborough that said the cancellation provision in Eastwood’s standard contract are “unconscionable” — or so unfair and unreasonable that they’re unenforceable.

The builder has long-maintained language in a specific contract clause gives the company unilateral authority to cancel agreements at any time prior to closing if a “bonafide dispute” arose. The clause also gave Eastwood the sole discretion to define what a “dispute” is.

The builder doubled-down in a 2024 hearing, so much so that Allen Nason, the company’s general counsel, said that cancellations are up to “the seller’s sole judgment, so I don’t really care what your opinion is. It is only my opinion that matters, period."

After Eastwood was twice denied, it then petitioned the state Supreme Court to take its case. But the high court ruled March 11 in a one-sentence order: “Based on the vote of the court, the petition … is denied.”

Eastwood’s lawyer, Ward Bradley, did not respond to a request for comment.

The buyers, who planned to move from all over the U.S. to Johns Island, entered into separate contracts with Eastwood from September 2020 to January 2021 to build houses to their specifications on lots they selected, according to the legal filing.

The prices ranged at the time from $534,000 to nearly $609,000.

For the last few years, the Swygert’s Landing homes have sat vacant and in various stages of construction — some completed while others have bare-bones foundations.

The lawsuit alleges Eastwood suddenly terminated their contracts citing a "legal error" in the paperwork, asking the buyers instead of waiting for a fix to negotiate a new contract for the same property at "current market value."

By that time, home prices in the area had risen to upwards of $800,000.

A majority of the homeowners have since found new living situations, but Appel said the Supreme Court ruling now brings the original, individual lawsuits against the builder back into play. The breach of contract complaints had stalled for years to focus on the combined lawsuit.

“We are excited to get through these appeals and get these cases in front of a jury,” said Michael T. Cooper of Apostolou Law Firm, who is co-counsel for the buyers. “Like the appellate courts have done, we believe the jury will ultimately side with these innocent home buyers and look forward to that day.”

The nine individual lawsuits are now “back on track,” Appel said. The main outcome at this point is damages, rather than following through on the sales.

“We have a lot of time and money tied up into this. As far as lost equity, we lived in an apartment for three years hoping we’d get it… so we weren’t paying a mortgage then,” Galvinos said. “If we would have gotten the house when we were supposed to, we’d have a sub-3-percent mortgage. So you’re talking about all of that and storage for three years.”

The builder said they’d most likely tear the homes down anyway, Raborn said. Glavinos added that Eastwood told them “they’d never sell us the house anyway.”

While the March 11 ruling is only applicable for the nine buyers of these specific homes, Eastwood contracts around the state could potentially be affected because the disputed language must be removed, Appel said.
