Summer in New Hanover County means heat, humidity and air conditioners that can spend long stretches working to keep homes comfortable. From Wilmington and Ogden to Porters Neck, Carolina Beach and Kure Beach, cooling systems across the area get plenty of use once temperatures climb. Carolina Comfort Air provides AC repair and maintenance throughout the Wilmington area and surrounding New Hanover County communities.
That extra workload can also bring existing problems to the surface. Most homeowners won’t know that a capacitor is failing or that refrigerant is low. What they notice is that the AC won’t turn on, the house isn’t getting cool or there’s suddenly water around the indoor unit.
Here are five common summer AC repairs and the warning signs homeowners are more likely to notice first.
1. AC Not Kicking On? Start With This Common Summer Failure
You lower the thermostat and expect the AC to kick on, but nothing happens. Maybe the outdoor unit clicks or hums without actually starting, or the fan isn’t spinning.
One possible culprit is a failed capacitor.
A capacitor is a small electrical component that helps provide the energy needed to start and operate parts of your cooling system, including the compressor and fan motors. When one begins to fail, the AC may struggle to start, shut off unexpectedly or hum without fully running. Trane identifies humming, difficulty starting and a lack of cold air as possible signs of capacitor or fan-related problems.
Because capacitors hold an electrical charge, this isn’t a repair homeowners should attempt on their own. If you’ve checked the thermostat and breaker and the system still won’t start normally, it’s best to have an HVAC technician diagnose the issue.
2. When Cool Air Suddenly Isn’t So Cool
Your air conditioner is running. Air is coming through the vents. The problem is that it doesn’t feel nearly as cold as it should.
You may also notice the system running for unusually long periods without reaching the temperature on the thermostat, or you may see ice beginning to form on refrigerant lines.
There are several reasons an air conditioner may stop cooling properly, including airflow problems, dirty components and refrigerant issues. Carolina Comfort Air specifically recommends professional diagnosis when a system isn’t properly cooling a home.
If refrigerant is low because of a leak, simply adding more refrigerant doesn’t address the underlying issue. The system should be inspected to determine why the refrigerant level dropped and whether a repair is necessary.
3. Why Your AC May Be Dripping or Leaking Water
Seeing a puddle near your indoor AC equipment can make it look like something major has failed, but sometimes the cause is much simpler.
Your air conditioner removes moisture from the indoor air while it cools your home. That moisture collects as condensation and normally drains away through a condensate line. During humid New Hanover County summers, that drainage system has plenty of work to do.
Over time, algae, dirt and other buildup can clog the drain line. Water can then back up into the drain pan or begin leaking around the equipment.
Some systems also have a safety switch that shuts the AC down when water begins backing up. That means a clogged drain can sometimes leave you wondering, “Why did my AC suddenly stop working?”
Drain maintenance is one reason regular HVAC maintenance is important. Carolina Comfort Air’s maintenance service includes cleaning evaporator coils, drain pans and drain lines as part of system care.
4. When the Air Stops Moving Like It Should
Sometimes the AC seems to be running, but you’re barely feeling air from the vents. Other times, the indoor system may be operating while the large fan on the outdoor unit isn’t spinning at all.
Your cooling system relies on fans in multiple places.
The indoor blower pushes conditioned air through the ductwork and into your rooms. The outdoor condenser fan helps the AC release heat outside. Problems with either one can reduce cooling performance.
A failing blower motor can result in weak or inconsistent airflow throughout the house. An outdoor fan problem can prevent the condenser from operating properly and may eventually cause the system to overheat or shut down. Capacitors and other electrical components can sometimes cause similar symptoms, which is why it’s important to diagnose the actual source of the problem rather than assuming the fan itself has failed.
If you’re experiencing poor airflow, hot and cold spots or an AC that continuously runs without cooling properly, Carolina Comfort Air recommends having the system evaluated by an HVAC professional.
5. Ice on the System Could Mean Trouble Below the Surface
Seeing ice on your air conditioner during a 90-degree summer day seems backwards, but frozen AC systems are a real problem.
You may notice frost or ice around refrigerant lines, the indoor coil or other parts of the system. At the same time, your AC may run constantly while producing very little cool air.
A frozen evaporator coil is usually a symptom of another problem rather than the root cause itself. Restricted airflow, dirty filters, blower issues and refrigerant problems can all contribute to the coil becoming too cold and freezing.
If you notice ice, shutting the system down and allowing it to thaw may remove the ice, but it doesn’t necessarily solve whatever caused the problem.
Repeated freezing is a good sign that it’s time for professional AC service.
Coastal Summers Make AC Maintenance Even More Important
Not every repair can be avoided, but regular maintenance gives a technician a chance to spot problems before they turn into a mid-summer breakdown.
During a maintenance visit, technicians can inspect wiring and system operation, clean components, clear drain pans and lines, and check for other signs of trouble. Carolina Comfort Air’s current maintenance program includes biannual visits, system testing, wiring inspections and cleaning of evaporator coils and drain lines.
That’s especially useful in New Hanover County, where air conditioners regularly deal with hot, humid coastal summers. Carolina Comfort Air serves Wilmington as well as communities including Wrightsboro, Murrayville, Porters Neck, Castle Hayne, Ogden, Carolina Beach, Kure Beach and Wrightsville Beach.
Know the Warning Signs Before Your AC Quits
Your cooling system doesn’t have to completely quit before it tells you something is wrong.
Warm air, weak airflow, humming or clicking sounds, water near the indoor unit and ice on the system are all signs worth paying attention to. Catching a problem early may give you a chance to address it before you’re left without AC during one of the hottest stretches of summer.
