Wilmington Island sits surrounded by saltwater marshes, creating humidity levels that make the air feel like soup. Many residents buy new air conditioners to combat the brutal heat, only to find themselves searching for AC repair in Wilmington Island, GA, within weeks of installation.
We frequently receive calls asking, “Why is my brand-new AC not working properly?” from homeowners frustrated by what appears to be a wasted investment.
If this sounds familiar, don’t worry; most new cooling problems stem from simple issues that won’t permanently damage your system.
Let’s examine five common brand-new AC issues and how to fix them.
AC Failure Symptoms You Shouldn’t Ignore
Proper new AC unit troubleshooting starts with recognizing these early warning signs before they escalate into costly repairs.
- Warm air blows from vents
- The system constantly runs without reaching the set temperature
- Unusual rattling, buzzing, or grinding noises
- Energy bills are significantly higher than expected
- Some rooms feel properly cooled, while others remain warm
- The system turns on and off repeatedly in short cycles
Identifying these new AC system failures early extends the life of your system.
Five Reasons Your Brand New AC Is Not Working After Installation in Wilmington Island, GA
The following sections cover the most common and preventable causes of cooling failure in new installations.
1. Incorrect Thermostat Settings Prevent Proper Cooling
Before assuming your system isn’t cooling properly, check the thermostat settings. Ensure the system mode is set to “COOL” and not “HEAT” or “OFF.” Set the temperature lower than the current room temperature. The fan should be set to “AUTO,” not “ON,” for proper cycling. For programmable thermostats, make sure the time and day settings are correct.
Many service calls are due to these simple setting errors. A quick check could save you time, frustration, and money.
2. Blocked Airflow Restricts Cooling Capacity
Blocked vents and registers trap cooled air in the ducts, creating back pressure that stresses your AC and reduces its efficiency. This is a common answer to the question, “Why is my brand-new AC not working?”
Make sure you open every vent in your house, even in rooms you don’t use often. Ensure no furniture, drapes, or rugs block the airflow from the vents. Return air grilles should stay unobstructed by furniture or decor.
These simple checks prevent pressure buildup and help your system cool more efficiently throughout your home in Wilmington Island, GA.
3. Dirty Air Filters Reduce Efficiency From Day One
Construction dust, debris, and other common pollutants clog new filters, reducing your AC’s efficiency. A dirty filter blocks airflow across the cooling coils, forces the blower motor to work harder, and prevents proper dehumidification.
Replace filters every month, especially during periods of high usage. In Wilmington Island’s dusty, humid environment, this small task prevents many cooling issues that threaten to damage your system.
Pay extra attention during the first month, as construction dust can often cause AC issues even before you receive your first power bill.
4. Installation Errors Compromise System Performance
Proper installation plays a critical role in your AC’s long-term performance. Some common mistakes include improper system sizing, incorrect refrigerant charge, unsealed ductwork connections, and electrical wiring issues.
These errors cause your brand-new AC to perform poorly right from the start. Professional installers follow strict manufacturer guidelines to avoid these issues.
If your AC is not working properly right after installation, the problem often lies in one of these basic mistakes. Proper installation from the professionals at Georgia Air Conditioning & Heating Repair ensures your system works at peak efficiency from day one.
5. Component Defects Need Professional Attention
Faulty compressor valves, defective fan motors, and refrigerant leaks occur more often than you might think in Wilmington Island, GA.
These issues demand professional diagnosis with specialized equipment. Manufacturer warranties usually cover most component failures, so be sure to document all symptoms. This helps our technicians identify the problem quickly and get your system up and running again.
