Larsen Energy Systems is HVAC repair that runs in the family! Established in the early 70s as “AAA Energy”, decades of excellent results and wide county framework consistently provided a broader, satisfied business and customer base. AAA Energy in its third generation was expanded and rebranded “Larsen Energy Systems” in 2009. The business has been working on residential and commercial HVAC service throughout Marin and Sonoma Counties.
Owner Casey Larsen started projects for his father during the summer of 1999, and never stopped working. Casey has worked on grand scale projects like Hall Winery in St. Helena and Dominican University in San Rafael. After 4 years of working on commercial buildings, Casey has focused his work primarily on residential housing all over Sonoma County, including the rebuilding and relief work efforts after the devastating Tubb’s fire of 2017. The philosophy of Larsen Energy System is doing the job right the first time.
This is what sets Casey Larsen and Larsen Energy Systems apart from other HVAC companies. With knowledge, experience and honesty, you can be sure that the job will be done right.
