Our Story

Brennen Futa's journey into the trades began right after high school. His passion for problem-solving and fixing things naturally led him to the HVAC industry. Over the years, Brennen gained extensive experience and honed his skills, but he also noticed significant gaps in the industry—particularly in communication, customer service, and honesty. Growing up with parents who are both entrepreneurs with a background in marketing and creating amazing client experiences, he was determined to set a new standard. Continuing the tradition of family businesses, the Futa’s founded Bulldog Heating & Cooling with the goal to to bring integrity and transparency to every service call creating customers for life!
