Common AC Issues We Fix
AON Heating & Cooling has helped homeowners and business owners across Arlington Heights fix a wide range of air conditioning problems. If any of these sound familiar, we’ve got the tools—and experience—to fix them:
- System blowing warm air: This often points to refrigerant issues, dirty coils, or thermostat problems. We’ll pinpoint the issue and restore your cooling.
- Short cycling (turning on and off too frequently): Usually caused by airflow restrictions, sensor problems, or incorrect system sizing. We diagnose and correct the cause to protect your system.
- Uneven temperatures in different rooms: This could stem from poor airflow, duct issues, or zoning problems. We fine-tune your setup for even cooling throughout the space.
- Strange noises during operation: Grinding, rattling, or buzzing often signals a loose or worn-out component. We’ll get to the source before it becomes a costly breakdown.
- High indoor humidity: Your system may not be dehumidifying properly. We’ll test and adjust your equipment to keep moisture under control.
