Sandoval Heating and Air Conditioning | Expert HVAC Repair in Upland, CA

Our maintenance service is designed to keep your system running efficiently through Upland's seasons. We perform a comprehensive check, including cleaning coils, checking refrigerant levels, inspecting electrical connections, and testing the thermostat. A key focus is ensuring the air handler fan is operating smoothly, which is a common point of wear. This proactive care helps prevent major breakdowns during peak summer heat or winter cold, improves your system's lifespan, and maintains good indoor air quality.

Correct sizing is critical for comfort, efficiency, and system longevity, especially in Upland's climate. An oversized system will short-cycle, turning on and off too frequently, which strains components, increases humidity, and leads to uneven temperatures. An undersized system will run constantly, struggling to keep up and driving up energy bills. With over 30 years of experience, we perform detailed load calculations for your specific home—considering its size, insulation, windows, and orientation—to recommend a system that provides consistent, efficient comfort.

Uneven cooling is a frequent symptom of air handler fan issues, which are common in our area due to dust and system strain. The blower motor or fan belt may be wearing out, or the fan itself could be dirty or unbalanced, reducing airflow. As specialists who focus solely on HVAC, we can quickly diagnose if the issue is with the air handler, ductwork, or another component. Prompt repair of fan problems not only restores comfort but also prevents further strain on your compressor, which is a much costlier repair.
