Troubleshooting Common HVAC Issues: Expert Advice from Hydrick Mechanical Feb 03, 2026

Understanding how your heating, ventilation, and air conditioning (HVAC) system operates is crucial for maintaining a comfortable home environment. At Hydrick Mechanical, we are committed to helping our customers troubleshoot common HVAC issues before they turn into significant problems. In this guide, we share expert advice to keep your system running smoothly.

One of the most prevalent problems homeowners face is inadequate heating or cooling. If your HVAC system is not effectively regulating temperature, the first step is to check the thermostat settings. Ensure it is set to the desired mode (heating or cooling) and that the temperature is set accurately. A thermostat set incorrectly can lead to unnecessary service calls and discomfort.

Another frequent issue is reduced air flow. This can often be attributed to dirty air filters, which can obstruct air circulation. We recommend checking and replacing air filters every 30 to 60 days, depending on your usage, to maintain optimal air quality and system efficiency. Neglected filters not only reduce air flow but can also increase energy consumption, leading to higher utility bills.

Unexpected noises coming from your HVAC system are another sign of trouble. Rattling or buzzing sounds could indicate loose parts, while squealing might suggest a problem with the motor belt. It's essential to address these noises promptly to prevent more serious mechanical failures. In such cases, consulting an HVAC technician is advisable, as they can identify and fix the issue efficiently.

Leaking water around the HVAC unit can be alarming and is typically caused by a clogged condensate drain line or a faulty evaporator coil. Excess water should be cleaned up immediately to prevent mold growth or property damage. Regular maintenance checks by professionals, like those at Hydrick Mechanical, can help you avoid these messy situations.

Uneven cooling or heating throughout your home is another common complaint. This can result from ductwork issues or an improperly sized HVAC unit. Leaky ducts are often the culprit, causing conditioned air to escape. Sealing ducts and ensuring they are well-insulated can solve this problem. If the unit is not of adequate size for your home's needs, it may struggle to maintain a consistent temperature, warranting an assessment by a professional.

For homeowners experiencing frequent system cycling, where the HVAC unit repeatedly turns on and off, it could indicate short cycling, typically due to refrigerant leaks or pressure imbalances. Short cycling significantly reduces energy efficiency and can cause premature wear and tear. A thorough inspection by a qualified technician can pinpoint the root cause and offer effective solutions.

Finally, if your energy bills are rising without increased usage, your HVAC system might be the cause. Issues such as dirty coils, malfunctioning components, or an outdated system could be to blame. Regular servicing and energy audits can help you identify inefficiencies that might be costing you more than necessary.
