HVAC installations and repairs should always be done by certified technicians to avoid costly errors. It’s important to call certified HVAC technicians for AC repair and servicing to ensure your system is properly and safely restored (though, we will get into possible causes below).
What should you do when your AC system won’t cool properly?
- Check thermostat settings and confirm it’s set to “cool” with a lower setpoint than room temperature.
- Replace or clean the air filter to ensure good airflow.

Signs You Need AC Repair
Knowing when to call for AC repair can save you from unexpected breakdowns and costly repairs. If your air conditioning system starts making unusual noises, such as banging, rattling, or hissing, it’s a clear sign something isn’t right. Reduced airflow from your vents, warm air instead of cool, or a sudden spike in your energy bills are also red flags that your air conditioner may need attention. In Lawrenceville, GA, where the cooling season can be intense, it’s important to act quickly. Skilled technicians can diagnose and resolve issues before they escalate, ensuring optimal performance and extending the life of your system. Regular maintenance services are key to catching small problems early, so your air conditioning system, heating and air, and even your new system installations continue to deliver comfort and efficiency all season long.

Understanding Your Air Conditioner
Your air conditioner is a complex piece of equipment designed to keep your home or business cool and comfortable, even during the hottest days in Lawrenceville, GA. At its core, the system relies on components like air filters, electrical connections, and refrigerant to remove heat and humidity from the air. Clean air filters are essential for maintaining both energy efficiency and indoor air quality, while secure electrical connections ensure safe and reliable operation. Regular maintenance by experienced HVAC technicians helps identify potential issues, optimize system performance, and extend the lifespan of your air conditioner. By partnering with a reputable HVAC company, you can benefit from professional advice on improving efficiency, reducing operating costs, and maintaining a healthy indoor environment year round. Trust skilled technicians to keep your air conditioning system running smoothly, so you can enjoy cool, clean air whenever you need it.
Low Refrigerant: A Common AC Cooling Issue
There’s a fairly common misconception among homeowners that refrigerant is something that needs to be refilled (recharged) on a regular basis—that it’s just a part of routine air conditioning maintenance. This is not the case, however. The truth is, if your air conditioner is losing refrigerant, it means that your system has a leak. In many cases, scheduling fast AC repair service can prevent further damage and restore your cooling quickly. Checking refrigerant levels is a key part of comprehensive AC maintenance and can help identify such issues early. Professional HVAC services include thorough refrigerant checks as part of their maintenance routines to ensure optimal system performance and prevent costly repairs.
The problem with this is that it causes ice to form on the coils, which insulates said coils, and makes it impossible for them to absorb heat as they are supposed to. As a result, you’ll see a reduced level of cooling. If you suspect you might have a refrigerant leak, please call our team right away.
Overheating AC Parts That Disrupt Cooling
This could be your fan motor. This part goes through a lot of work over the years, and as a natural part of wear and tear, it can wear down to the point that it requires replacement. Detailed inspections during maintenance can identify issues like worn or loose belts, which might also contribute to reduced cooling. If you continue to try running your air conditioner with an overheating component of any kind, the heat it generates can bleed into the air, which is why you’ll feel reduced cooling.
Leaky Ductwork and Its Effect on AC Cooling
Did you know you can lose up to 30% of the cooled air you’re paying for through damaged ductwork? Even the smallest pinhole leak can cause your cooled air to escape into unoccupied spaces in your home, such as the attic or crawlspace. Cleaning or replacing air filters during maintenance also improves airflow and air quality, helping to maximize the efficiency of your cooling system.
It can also suck in hot air from your home. For this reason, you’ll feel lukewarm air coming from your vents—and unfortunately you’ll still be paying the same for your AC use. This is definitely a situation you want to have remedied by a professional right away.
Reduced Cooling Means Reduced Efficiency
With an air conditioning system, efficiency is vital. Scheduling maintenance before the cooling season begins ensures your air conditioners operate at optimal performance and helps prevent breakdowns during the hottest months in Georgia. AC units that receive regular maintenance have an extended lifespan, allowing you to get the most out of your investment. If your air conditioner isn’t blowing cooled air in the required amounts, it will work harder than it should have to in order to do its job, causing your monthly cooling bills to rise, and increasing the strain on other components within the cooling system. If you’ve experienced this before, you may wonder how often AC units need repair—and how to know when it’s time to call in a professional.
Ultimately, this reduces efficiency and raises your energy bills, too. The best thing you can do to avoid this is to contact us right away when you suspect you have a problem, and be sure to schedule annual professional maintenance for your cooling system—including air conditioners, heating system, heating systems, and furnaces—and biannual maintenance if you have heat pumps, as they require specific attention for year-round performance. Regular tune-ups help maintain energy efficiency in air conditioning units, ensuring they operate at peak performance. Maintenance plan members enjoy priority scheduling, ensuring faster service when you need it most. If you continue to experience persistent efficiency issues, it may be time to consider a new system and professional installation for improved comfort and reliability.

DIY Troubleshooting
Before you pick up the phone for professional air conditioning service in Lawrenceville, GA, there are a few simple troubleshooting steps you can try at home. Taking these actions can help you identify minor issues, improve energy efficiency, and even prevent costly repairs down the road. Plus, regular attention to your air conditioning system and indoor air quality solutions can ensure your home stays comfortable and your equipment runs at optimal performance all year round.
- Check Air FiltersA clogged or dirty air filter is one of the most common reasons for reduced airflow and poor cooling. Not only can this impact your air conditioner’s efficiency, but it can also affect your indoor air quality. Make it a habit to inspect your air filters monthly and replace or clean them as needed to keep your system running smoothly.
- Inspect Electrical ConnectionsLoose or damaged electrical connections can cause your air conditioning system to malfunction or even pose a safety risk. If you notice any frayed wires or loose terminals, it’s best to call a professional HVAC technician for electrical services. Never attempt complex electrical repairs yourself.
- Look for Signs of LeaksKeep an eye out for any moisture or pooling water around your air conditioning unit, which could indicate a refrigerant leak or drainage issue. Leaks can reduce your system’s efficiency and lead to major problems if left unaddressed. If you suspect a leak, contact a trusted HVAC company serving Lawrenceville for expert service.
- Check Thermostat SettingsSometimes, the solution is as simple as adjusting your thermostat. Make sure it’s set to “cool” and that the temperature is set lower than the current room temperature. If your thermostat uses batteries, try replacing them to ensure accurate readings.
- Listen for Unusual NoisesStrange sounds like grinding, squealing, or hissing coming from your air conditioner can signal trouble. Unusual noises often point to issues that require professional attention, so turn off your system and schedule a service call with skilled technicians if you hear anything out of the ordinary.
- Check for Proper AirflowWalk around your home and make sure all vents are open and unobstructed. Blocked vents can restrict airflow, making your air conditioning system work harder and reducing its energy efficiency. Clear away any furniture, drapes, or debris that might be blocking your vents.
- Consider Indoor Air Quality SolutionsBeyond just cooling, your HVAC system plays a big role in your home’s air quality. Air cleaners, humidifiers, and dehumidifiers can help remove allergens and maintain a healthy environment. Ask your HVAC professionals about indoor air quality services to further enhance your comfort.

Frequently Asked Questions
Question: What are the most common reasons my AC system isn’t cooling?
Answer: Common causes include a clogged air filter restricting airflow, low refrigerant due to leaks, thermostat issues such as mis‑setting or faulty calibration, and outdoor unit problems like dirty condenser coils or broken fan and compressor components.
Question: How often should I replace or clean the air filter?
Answer: Air filters should be checked monthly during heavy use and replaced or cleaned every 1–3 months depending on dust and filter type. A clogged filter reduces airflow and cooling efficiency, and can lead to frozen evaporator coils or system strain.
Question: Why isn’t cooling working even though the AC unit seems to run?
Answer: If the unit runs but doesn’t cool, possible issues include low refrigerant levels, a failed compressor motor, frozen evaporator coils, or a broken condenser fan—all of which impair heat exchange and require professional attention.
Question: Could a thermostat problem prevent proper cooling?
Answer: Yes. If the thermostat is set incorrectly, batteries are low, wiring is faulty, or it’s mis‑calibrated, the AC may not engage cooling mode. Ensure thermostat is set to “cool” with the set temperature below ambient.
Question: When should I call a professional HVAC technician?
Answer: Call a certified technician if you suspect refrigerant leaks, compressor failure, a broken outdoor fan, frozen coils, or if reset breakers and filter changes don’t restore cooling. Complex and electrical issues are best handled by trained professionals.
