What do customers say?

Goliath Mechanical earns strong marks for fast response times and quality AC work, with Larvell named repeatedly as a dependable technician. Two older complaints flag serious concerns: one tech allegedly bypassed a safety switch instead of fixing the real problem and left no documentation; another promised follow-up on quotes that never arrived. The bulk of recent reviews praise punctuality and fair costs, but the safety-switch incident suggests occasional quality control lapses.

Based on limited recent reviews, so treat this as low-confidence.

Praised for
  • responsive and quick
  • professional technicians
  • fair pricing
  • Larvell trusted across multiple jobs
Watch-outs
  • dishonest repair (safety switch bypass)
  • no follow-up on quotes and receipts

Worth knowing

  • 3-year maintenance agreements offered with AC replacements
  • emergency response on July 4th and weekends documented
  • replaced 21-year-old unit in one case; replaced air handler in another

Lucas and his team show up fast, especially during emergencies. Reviewers praise their honesty-they fix problems without pushing unnecessary parts, explain what they're doing, and charge fairly. Techs arrive same-day or even late into the evening when the AC fails in 107-degree heat. Service ranges from AC and heating repair to fireplace work and thermostat setup. One customer said Lucas saved them $2,000 by actually fixing a fireplace another company wanted to charge $2,000 to replace. Phone support is available even on weekends, and service call fees get waived sometimes.
