Our Family’s Commitment to Personalized HVAC Solutions
We started Arizona’s Best Heating and Cooling in Tucson in 2012, led by Oscar Leyva Sr., a proud veteran, and his son. Our mission has always been to deliver personalized HVAC care rooted in reliability, skilled craftsmanship, and genuine relationships. Every installation, repair, or maintenance visit includes direct owner involvement, ensuring trust and unmatched expertise.
Our Story
Arizona’s Best Heating & Cooling LLC is a family-owned and operated business founded by Oscar Leyva Sr. and his son, Oscar Leyva Jr. Oscar Sr. began his HVAC career in 1980, and in 2002, Oscar Jr. joined him in the field. While working for large companies, they noticed a major gap—customer service wasn’t a priority—and decided it had to change.
Personal Attention on Every Job
In 2012, they launched Arizona’s Best Heating and Cooling LLC with a clear mission: put the customer first. To ensure top-quality workmanship and service, Oscar Sr. and Oscar Jr. personally participate in every service call and installation, so you always know exactly who will arrive at your doorstep.
