That's likely condenser coil corrosion, a common issue in Palm Desert due to our hard water. The mineral buildup insulates the coils, drastically reducing cooling efficiency. We recommend a professional cleaning with specialized solutions and can install preventative filters or recommend corrosion-resistant components to protect your system long-term.

That often points to a problem with the air handler fan assembly. In our desert environment, dust and debris can accumulate on the fan blades or motor, causing imbalance, noise, and reduced airflow. We'll inspect, clean, and balance the fan system and check the motor and belts for wear. Prompt repair prevents further strain on your entire HVAC system.

We advise bi-annual professional tune-ups—once before the intense summer heat and again before winter. These visits include cleaning condenser coils to combat corrosion, checking and lubricating air handler fan motors, inspecting electrical connections, and ensuring refrigerant levels are correct. This proactive care is crucial here to maintain efficiency and extend the life of your equipment against our harsh climate.
