A to Z Services - Lubbock's Licensed HVAC Services

First, check your thermostat settings and circuit breaker to ensure power is reaching the unit. If those are fine, it's best to call A to Z Services immediately. Our technicians are experienced with Lubbock's extreme heat conditions and can quickly diagnose common issues like refrigerant leaks, compressor failures, or electrical problems that often occur during heatwaves. We prioritize emergency calls during hot weather to restore your cooling as soon as possible.

Signs of thermostat wiring issues include your HVAC system not turning on/off properly, temperature readings being inaccurate, or your thermostat display being blank. Our technicians at A to Z Services perform thorough diagnostics to identify faulty wiring, loose connections, or compatibility problems. We repair or replace damaged wiring with quality materials suited for Lubbock's climate, ensuring your thermostat communicates correctly with your HVAC system for reliable temperature control.

We recommend bi-annual maintenance - once before summer and once before winter. Our service includes cleaning coils, checking refrigerant levels, inspecting electrical components, and testing thermostat calibration. This proactive approach helps identify potential issues like worn wiring or aging components before they cause breakdowns during Lubbock's temperature extremes. Regular maintenance can extend your system's life and improve energy efficiency in our local climate.
