Vegas Knight Air | Certified HVAC Repair in Las Vegas, NV

In our extreme heat, a failing capacitor is a common culprit. Watch for your outdoor unit humming but not starting, the system shutting off randomly, or weak airflow from your vents. These symptoms often point to a capacitor struggling in the high temperatures. We carry a wide range of capacitors on our trucks for most Las Vegas-area systems and can typically diagnose and replace them during a single service call to restore your cooling quickly.

We start with a thorough evaluation of your home's layout, insulation, and your specific comfort needs. For a replacement, we focus on properly sizing a new, energy-efficient system that won't be overworked by our desert climate. Our licensed technicians handle the entire process—from safely removing the old unit to installing and calibrating the new system—and we ensure all work meets local codes. You'll receive a detailed quote upfront and guidance on available rebates for high-efficiency models.

Yes, we recommend scheduled maintenance, especially before the intense summer heat arrives. Our plans include cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring the entire system is operating efficiently. This proactive service helps catch small issues, like a weakening capacitor or a dirty condenser coil that can cause overheating, before they lead to a major breakdown during a heatwave, saving you money and discomfort.
