Five Star Heating and Air LLC has been a cornerstone of Jacksonville's HVAC service landscape since 2007, built on the foundation of military service and family values. Founded by Christopher A. Null, a retired U.S. Navy Chief Petty Officer (E-7), the company has maintained an impressive 4.9-star rating across 83 customer reviews—a testament to their unwavering commitment to quality and customer satisfaction. Brandon, the current owner and son of the company's founder, continues the family legacy with the same dedication and professionalism that Chris instilled from day one. With over 10 years of experience, Five Star has become known throughout Jacksonville, Jacksonville Beach, and as far as Ponte Vedra for reliable, expert HVAC solutions. Their motto, "experienced service you can trust," perfectly encapsulates their approach to every job. The company offers comprehensive services including AC and heat pump installations, repairs, emergency service, preventative maintenance, and advanced diagnostic work using thermal imaging. They handle everything from compressor replacements to thermostat calibrations, serving both residential and commercial clients. Their service area spans from Jacksonville's beaches to the west side, with a strong reputation for prompt response and thorough workmanship.
