Night & Day Heating & Air Conditioning - Dallas's Trusted HVAC Services

This is a common issue in our Texas heat. Often, it's due to a dirty condenser coil restricting airflow, low refrigerant levels, or a failing capacitor. Our technicians perform a thorough diagnostic to pinpoint the exact cause—like checking for debris buildup or measuring refrigerant charge—and provide a precise repair to restore reliable cooling and prevent system damage.

Signs include uneven temperatures between rooms, higher-than-normal energy bills, and excessive dust. We use specialized tools, like duct blaster tests or thermal imaging cameras, to locate leaks in your ductwork, often in attics or crawl spaces. Our solution involves professionally sealing these leaks with mastic or metal-backed tape, which can significantly improve your system's efficiency and comfort.

Given our intense summers and variable winters, we recommend bi-annual maintenance. In spring, we focus on cooling: cleaning coils, checking refrigerant, and ensuring the compressor is ready for the heat. In fall, we service the heating system, inspect heat exchangers, and test ignition systems. This proactive care helps prevent common local failures, extends equipment life, and maintains peak efficiency year-round.
