About Onyx HVAC
12+ years serving Phoenix and surrounding areas
Founded in 2010, Onyx HVAC started as a small family business with a mission to provide reliable heating and cooling solutions to Phoenix residents. Over the years, we've grown into a trusted name across Maricopa County, known for our honest service and deep local knowledge.
We believe in doing the job right the first time. Our technicians are not just skilled professionals—they're your neighbors who understand the unique challenges of desert living. From routine maintenance to emergency repairs, we treat every home as if it were our own.
As part of the Phoenix community, we're committed to giving back. We sponsor little league teams, participate in local charity events, and offer special discounts for seniors and military families throughout the year.
