In our extreme desert climate, AC capacitors work hard and can fail. Common signs include your outdoor unit humming but not starting, the system turning on and off frequently, or a complete lack of cooling.

Our maintenance service is designed to keep your system efficient and catch small issues before they become big problems. A visit includes cleaning condenser coils, checking refrigerant levels, inspecting electrical connections, testing system controls, and ensuring the thermostat is calibrated. For Las Vegas homes, we pay special attention to components under the most stress from constant use. This proactive care helps improve performance, indoor air quality, and can prevent costly breakdowns.

An AC unit that's too large or too small for your home is a common issue with major consequences. An oversized system will short-cycle, turning on and off too frequently, which leads to uneven cooling, higher humidity, and increased wear. An undersized unit will run constantly, struggling to cool your home and driving up energy bills. Our installation process begins with a detailed load calculation of your home to recommend a correctly sized, energy-efficient system that provides consistent, reliable comfort for our desert climate.
