Cost Saving With Regular AC Maintenance
It is a little-known fact that over half of all major repairs could have been avoided with regular AC tune-ups. Beyond this, a well-maintained unit works at peak efficiency and saves you money each month.
While many people may think of AC maintenance as just another added expense, history has shown it is one of the best moves you can make. You save money on a continual basis, have less stress over your unit breaking down, and if a failure should occur, it is more likely to be a minor fix instead of a major failure.

Frequently asked Air Conditioning Questions
- Why is my AC blowing warm air in the middle of summer?
If your AC is blowing warm air during a Gastonia summer, it's usually related to airflow or refrigerant. Dirty filters, a blocked condenser coil, or low refrigerant levels can all keep cool air from circulating properly. Sometimes, the thermostat might be set to “fan” instead of “cool,” causing it to push unconditioned air. Electrical or compressor issues can also prevent the system from cooling effectively. Before assuming the worst, check your filter and thermostat settings; if those look fine, it’s time for a professional to inspect for leaks or component failures. The Roland Black Heating & Cooling team can quickly diagnose the issue and restore your home’s comfort.
- Why is my AC running but not cooling?
When your AC runs but doesn’t cool, it’s often a sign of low refrigerant, dirty coils, or a failing compressor. It may also mean the outdoor condenser isn’t expelling heat properly due to debris or a bad fan motor. In some cases, thermostat miscommunication or electrical issues can prevent the system from cycling correctly. Start by checking your thermostat settings and air filter. If both are fine, the issue likely needs professional diagnosis. Continuing to run the system without cooling can cause more damage, so it’s best to have it checked promptly.
- How do I reset my central AC not blowing cold air?
To reset your central AC, start by turning the thermostat off and switching the breaker connected to the system to the “off” position. Wait about five minutes, then turn the breaker and thermostat back on. Many systems also have a reset button on the outdoor unit (typically red or yellow) that you can press and hold for a few seconds. This clears basic electrical faults and can resolve temporary lockouts. If your system still won’t cool afterward, the issue could be deeper, like a failed capacitor or refrigerant problem.
- How to tell if AC is low on refrigerant?
When your AC is low on refrigerant, you’ll often notice warm air, longer cooling cycles, or ice buildup on the refrigerant lines. You might also hear a subtle hissing or bubbling sound from the indoor or outdoor unit; that’s the refrigerant escaping. Utility bills may creep up because your system is working harder to reach temperature. Low refrigerant isn’t normal and indicates a leak somewhere in the system. Since refrigerant is a closed loop, only a licensed technician can safely test, locate, and recharge it. That’s where the certified professionals at Roland Black Heating & Cooling come in — we’ll find the leak, repair it properly, and get your system running efficiently again.
- What is the most common AC repair?
The most common AC repair we see around Gastonia is a capacitor replacement. Capacitors provide the initial jolt of energy your system’s compressor and fan motors need to start up. Over time, heat and electrical wear can cause them to fail, especially during peak summer months. Other frequent issues include clogged filters, refrigerant leaks, and contactor problems. Routine maintenance is the best way to catch these small issues early before they lead to costly breakdowns.
- What should my AC be set to if it’s 100 degrees outside?
On extremely hot days, the ideal setting for both comfort and efficiency is around 75–78°F. It’s tempting to drop the thermostat lower, but your system can only cool your home about 20 degrees below the outdoor temperature. Running it much colder won’t make it work faster. It’ll just strain components and raise energy costs. Use ceiling fans to help circulate cool air and keep blinds closed during the hottest part of the day. Small adjustments like these help your AC stay efficient even in Gastonia’s summer heat waves.
- Why is my AC set to 72 but reads 78?
When your thermostat says 72 but the home still feels warm, it’s usually because the system can’t reach or maintain that target temperature. That could stem from dirty coils, low refrigerant, leaky ductwork, or simply an undersized system struggling against the heat. Thermostat location also plays a role. If it’s in direct sunlight or near a draft, it might read inaccurately. In Gastonia’s summer humidity, even small airflow restrictions can make a big difference. Checking filters, vents, and thermostat placement is a good first step before calling for service.
- Should I turn off my AC if it is not cooling?
Yes — if your AC is running but not cooling, it’s best to turn it off. Running it in that condition can cause further damage, especially if refrigerant levels are low or coils are frozen. Once it’s off, check your air filter and ensure the outdoor unit is free of debris. Give it about an hour to thaw if you see ice buildup. If it still doesn’t blow cool afterward, that’s a sign to schedule a diagnostic before restarting the system. Contact Roland Black Heating & Cooling to schedule a professional inspection — we’ll identify the cause and get your cooling system back to normal quickly and safely.
