Troubleshooting Constant AC Operation
When your AC can’t seem to take a break, it’s not just the machine that wears out; your patience and budget can wear thin, too. Constant operation is a common problem for homeowners that can be solved with a little DIY effort and professional help. If your AC is always on but not cooling your home efficiently, this guide is for you.
The HVAC experts at Patriot Air are here to break down how ACs work, why they can run constantly, and why that’s an issue. We’ll provide practical tips for troubleshooting and advice on when to call a professional.
Understanding AC Operation
Air conditioning is a staple of modern comfort, especially during those scorching summer months. But how exactly does an AC system keep your home cool and comfortable? At its core, air conditioning operates on the principles of heat transfer.
- The AC unit takes in warm air from inside the home.
- The warm air cools by passing over a set of evaporator coils containing refrigerant.
- The cool air is redistributed throughout the home.
- The absorbed heat is expelled outside through condenser coils.
This process involves a few key components working together: the compressor, which pumps the refrigerant through the system; the evaporator coils, which cool the indoor air; the condenser coils, which release the absorbed heat outside; and the thermostat, which regulates the overall operation based on your preferred settings.
What It Means If Your AC Is “Running Constantly”
When we say an AC is “running constantly,” we mean that the AC is not turning off when the set temperature is reached. An air conditioner is expected to work harder and longer on extremely hot days but it should still turn off periodically.
Is Continuous AC Operation A Sign Of Trouble?
It’s essential to differentiate between an AC system that’s working hard to combat extreme outdoor temperatures and one that’s struggling with underlying issues. On hot summer days, your AC will run longer cycles to reach the set indoor temperature. An efficient AC should be able to cool your home without running non-stop, even on the hottest days.
When does continuous operation signal that your AC is working too hard?
- If the AC is unable to reach set temperatures.
- If you notice a significant spike in energy bills.
- If your home is excessively humid.
The key thing to look out for is a change in comfort and performance without a change in usage.
Continuous operation is a sign that something has malfunctioned in the AC. This can increase wear and tear, shortening the lifespan of your system. It also drives up energy consumption, leading to higher utility costs. If your system can’t keep up without continuous operation, it’s likely experiencing problems that need attention.
Common Causes For Continuous AC Operation
An AC that runs constantly isn’t just a quirk; it’s a clue that something in the system needs attention. The issue may be as simple as a thermostat reset or a complex parts failure.
- Thermostat Settings: The thermostat is the director of your home’s climate control, telling the AC when to cycle on and off. Incorrect settings and cause your AC to run nonstop. Make sure that your thermostat is set to “auto” instead of “on” for the fan setting. “Auto” means the fan only runs when cooling is needed, while “on” keeps it running continuously. Additionally, set a realistic temperature that your AC can reach on hot days.
- Dirty Air Filters: Clogged filters are a common yet overlooked cause of continuous AC operation. Changing the filters every 1-3 months ensures proper airflow so the AC can cool your home efficiently.
- Low Refrigerant Levels: Refrigerant allows your AC to absorb heat from your home and release it outside. Low levels or insufficient charge can hold up this process and cause your AC to run constantly. Low refrigerant levels and leaks are best left to professionals.
- Faulty Components: From a struggling compressor to fan problems, mechanical issues can keep your AC running without adequate cooling results. Faulty components not only lead to inefficiencies but can escalate into more significant, costly problems if neglected.
DIY Fixes & When To Call A Professional
| Issue | DIY Fixes |
When To Call A Professional |
|
| Dirty Air Filters | Replace or clean the air filters every 1-3 months. | If you are unsure which filters are best or how to access them. | |
| Thermostat Issues | Ensure the thermostat is set to “auto,” replace batteries, and adjust the temperature settings to be more realistic. | If the thermostat is malfunctioning or needs recalibration or replacement. | |
| Continuous Operation WIthout Cooling | Check for open windows or doors. Improve home insulation. | If the AC still doesn’t cool efficiently after basic troubleshooting. | |
| Strange Noises Or Smells | Identify if the noise is coming from a loose part that can be easily accessed and tightened. | For electrical smells, burning odors, or if the source of the noise cannot be safely accessed or identified. | |
| High Energy Bills | Implement energy-saving practices, such as using fans and closing blinds during the day. |
