HVAC Repair Austin TX | Call Roger Brown Air Conditioning

This is a frequent issue we see. Often, it's due to a mismatched C-wire (common wire) providing inconsistent power, especially in older Austin homes. Our technicians can verify your wiring, install a proper C-wire if needed, or recommend a compatible thermostat that works reliably with your specific HVAC system to restore seamless control.

Absolutely. AC capacitor failure is one of the most common reasons for a sudden cooling loss in our area, especially during peak summer strain. The capacitor helps start the compressor and fan motors. We can quickly test and replace a faulty capacitor, often getting your cool air back flowing the same day to beat the Austin heat.

We strongly recommend twice-yearly maintenance, especially before summer. This proactive check includes inspecting and testing capacitors, cleaning coils affected by local pollen, and ensuring all electrical connections for your thermostat and system are secure. This simple service can prevent the majority of the emergency calls we see for capacitor and connectivity issues.
