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

You don't have to be a graduate from St Stephen Elementary School near St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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 St. Stephen, 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.

St Stephen’s College 2025-26 fees spark controversy as first-year students are asked to pay DU and college fees separately. The college lists DU fees over three times higher than the official Rs 3,500 share, raising compliance concerns. With total semester fees nearing Rs 30,000, students and DU officials question transparency under the dual-payment system.

St Stephen's College, one of Delhi University's premier affiliated institutions, has found itself in the midst of a fee controversy. For the academic year 2025-26, the college has asked its first-year students to pay the university and college fees separately, a so-called dual-payment system that appears to violate DU’s established single-portal payment rules. Even more startling, the ‘DU fee’ component listed by the college is more than three times the university's official share, prompting questions about compliance and transparency.According to the fee notice seen by the Times of India, first-year students in most programmes, including B.A. (Programme/Honours) and B.Sc. (Honours in Physics and Chemistry), are charged between Rs 11,551 and Rs 11,630 as the DU fee. Officially, DU’s annual share is Rs 3,500, leaving an apparent overcharge exceeding Rs 8,000 per student — a staggering 230% excess. With roughly 400 students in the first-year intake, this amounts to an extra Rs 32 lakh effectively paid to the university, though it remains unclear if these funds have been transferred directly or temporarily retained by the college, TNN reports.For students under the Persons with Disabilities (PwD) category, the DU fee is listed at Rs 1,150, against the university’s official Rs 875 — a 31% increase. Meanwhile, the college fee ranges from Rs 17,500 to Rs 19,000 per semester. Taken together, the total payable amount for a standard BA or BSc programme approaches Rs 30,000 per semester, significantly higher than first-year fees at comparable DU colleges, such as Miranda House with Rs 16,000–20,000 annually and Ramjas College with Rs 15,000–17,000 annually, TOI found.

College’s rationale and university response

Haneet Gandhi, Dean of Admissions at Delhi University, told TOI, “There is only one payment system. Students are required to pay their fees through the DU portal, from which the university keeps its share and transfers the rest to colleges. No other medium of payment can be created as per rules.” Gandhi confirmed that the university's official share was Rs 3,500 and called the excess listed by the college “the college’s fault.”According to Gandhi, DU has already transferred 60% of the college’s share from the total fees collected, including the inflated DU component. This indicates that the extra Rs 32 lakh paid as part of the DU fee may ultimately remain with the college rather than the university.Chinkhanlun Guite, Bursar and Public Relations Officer at St Stephen's, in an interaction with TOI, said, “It was done for the convenience of students.” When asked whether the college had sought DU’s permission for the separate system, he replied “No such permission is required,” and declined to comment on the nearly threefold DU fee listed. Repeated calls to Principal John Varghese went unanswered.The controversy highlights longstanding tensions between St Stephen's and DU over administrative autonomy. While the college cites its minority status to defend internal procedures, including separate interviews for applicants, DU insists that affiliated colleges adhere strictly to common regulations. As students pay hefty sums upfront, it underscores the need for clarity in how premier institutions communicate costs.
