About Goliath Mechanical Heating and Cooling
Goliath Mechanical Heating and Cooling has earned a reputation as one of the most reliable air conditioning contractors serving the Phoenix metropolitan area, including Ahwatukee, Tempe, Gilbert, and the surrounding East Valley communities. With a 4.8-star rating drawn from 40 client reviews, the company maintains round-the-clock availability, operating 24 hours every day of the week to address cooling emergencies that simply cannot wait in Arizona's extreme summer heat. The business appears to be owner-operated, with technician Larvell frequently mentioned by name in customer feedback as the primary point of contact for service calls and installations.
What distinguishes Goliath Mechanical from competing contractors in the Valley is their commitment to transparent communication and post-service follow-through. Multiple reviewers note that Larvell called back after job completion to confirm systems were running properly, a practice that few contractors maintain. The company offers service agreements for ongoing maintenance, and they demonstrate proficiency with smart home integrations including Nest thermostats, which require precise configuration to operate efficiently with modern high-efficiency systems. Their workflow emphasizes customer education, with technicians taking time to explain every step of repairs or installations.
Customer narratives reveal the hands-on nature of this operation. When Dan Ward's air conditioning failed right before a vacation departure, Larvell accommodated the situation despite the customer being out of town, completing a full replacement in approximately two and a half hours. Similarly, Carson Biggs described Larvell arriving promptly, providing detailed explanations before beginning work, and maintaining continuous updates throughout the installation process. These accounts suggest a contractor who prioritizes accessibility and clear communication over high-pressure sales tactics.
What Customers Say
All seven readable reviews award 5 stars, with Larvell specifically named in five of those testimonials as the technician delivering service. Multiple reviewers mention same-day or urgent-response scenarios, and three customers explicitly note follow-up calls after job completion to verify system performance.
