Common Air Conditioning Problems We Solve in Modesto, CA

In Modesto’s hot and dry summers, your air conditioning system plays a critical role in maintaining indoor comfort. When it falters, everything from your sleep quality to energy bills can suffer. At DeHart Plumbing, Heating, and Air Inc., we understand the urgency and discomfort of AC issues, and we’re here with fast, reliable solutions.

One of the most frequent issues our customers report is weak airflow. This can be caused by clogged filters, blocked ducts, or failing motors—all of which lead to inconsistent temperatures and rising utility costs. We also commonly address systems that cycle on and off too frequently, a problem often linked to incorrect sizing or thermostat faults.

Refrigerant leaks are another common concern, resulting in poor cooling and higher energy consumption. Low refrigerant levels not only impact performance but can also cause long-term compressor damage if ignored. Our technicians are trained to detect and fix leaks quickly, restoring your system’s efficiency.

Another widespread issue is unusual noises coming from your AC unit. Rattling, buzzing, or grinding sounds usually indicate loose components, worn belts, or failing fans—all of which should be addressed before they lead to complete system failure.

More AC problems we regularly solve include:

• Thermostat misreadings and calibration issues
• Frozen evaporator coils due to restricted airflow
• Drain line clogs causing water leaks and mold risk
• Electrical failures leading to non-starting systems
• Dirty or aging components causing performance drop-offs

The Modesto climate demands a lot from cooling systems, especially during extreme heatwaves. Whether your AC isn’t keeping up, is showing signs of wear, or has stopped working altogether, you can count on DeHart Plumbing, Heating, and Air Inc. to get it running right.
