ATD Mechanical: Experienced HVAC Services Serving Lexington, TX 78947

This is a common issue we see locally. Often, it's due to a minor wiring fault at the thermostat, a tripped safety switch on the furnace or air handler, or a power surge that disrupted the control board. Our technicians are experts at tracing these connectivity issues, ensuring your Wi-Fi thermostat and HVAC equipment communicate properly for reliable, scheduled comfort.

Our Texas heat is tough on compressors. The most frequent causes are a dirty condenser coil restricting airflow, low refrigerant levels causing the unit to overwork, or a failing capacitor or fan motor. ATD Mechanical performs thorough cleaning, pressure checks, and electrical testing to diagnose the exact cause. We provide the repair needed to restore efficient operation and prevent costly compressor failure.

Our preventative maintenance tune-up is key. It includes cleaning the condenser coil to prevent overheating, checking refrigerant levels and electrical components, and verifying all system controls—including your smart thermostat's wiring and signals—are functioning correctly. This proactive service helps catch small issues before they lead to connectivity drops or a complete system shutdown on the hottest days.
