South Plains Southern Comfort | Qualified HVAC Repair in Lubbock, TX

Signs of an improperly sized system in our climate include short-cycling (frequent on/off cycles), rooms that never seem to reach the set temperature, excessively high humidity indoors, and surprisingly high energy bills. An oversized unit cools too quickly without properly dehumidifying, while an undersized one runs constantly and struggles. Our technicians perform a Manual J load calculation, specific to Lubbock's weather, to determine the precise capacity your home needs for efficiency and comfort.

Yes, evaporator coil freeze-ups are a frequent issue here, often caused by restricted airflow from dirty filters or blocked vents, or by low refrigerant levels. When the coil freezes, air can't pass through to be cooled. The first step is to turn the system off at the thermostat to let the ice melt. Then, check and replace your air filter. If the problem persists, call us. We'll diagnose the root cause—like a refrigerant leak or a failing blower motor—and fix it to prevent recurring damage to your compressor.

Proactive maintenance is key to preventing sizing-related strain and coil freeze-ups. We recommend biannual tune-ups before summer and winter. Our service includes checking refrigerant charge and for leaks, thoroughly cleaning the evaporator and condenser coils, ensuring proper airflow by inspecting filters and ductwork, and calibrating thermostats. This not only prevents breakdowns but also ensures your system runs as efficiently as it was designed to, combating our dust, heat, and temperature swings effectively.
