HVAC Repair Austin TX | Call Modern Air Conditioning and Heating

In Austin's heat, short cycling is often caused by an oversized unit, a dirty air filter, or low refrigerant. It forces your system to work harder, leading to wear and higher bills. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause—whether it's a sizing issue, a refrigerant leak, or airflow blockage—and provide a targeted, lasting repair to restore proper operation and efficiency.

Absolutely. Capacitors, which help start the compressor and fan motors, are a common point of failure under Austin's heavy cooling load. A failed capacitor will prevent your system from starting. We prioritize these emergency calls, especially during heatwaves, and typically offer same-day or next-day service to diagnose and replace the faulty capacitor, getting your cool air flowing again promptly.

We recommend a pre-season tune-up each spring. This includes checking and tightening electrical connections, testing the capacitor and contractor, cleaning coils, checking refrigerant levels, and ensuring proper airflow. This proactive service catches small issues—like a weakening capacitor—before they cause a breakdown during the peak summer heat, saving you from emergency repairs and keeping your system running at peak efficiency.
