Semper Fidelis AC LLC is a veteran-owned HVAC company serving Naples, FL and all of Collier and Lee Counties. The name says it all — “Semper Fidelis” is the United States Marine Corps motto, meaning “Always Faithful.” That’s the standard we bring to every job.
Our Story
Founded by Marine veteran Jonny Lopez, Semper Fidelis AC was built on the values learned in service: integrity, accountability, and getting the job done right the first time. With over 20 years of hands-on HVAC experience, Jonny still works in the field alongside his team — diagnosing problems, installing systems, and making sure every customer gets the same quality of work he’d want in his own home.
How We Work
We keep things simple and honest. You get upfront pricing before any work starts — no surprise charges, no upselling, no pressure to replace a system that only needs a repair. We pull permits on every installation because Florida law requires it and because it protects you. We show up when we say we will, and we clean up when we’re done.
Licensed, Insured, and Reviewed
Semper Fidelis AC holds Florida HVAC License #CAC1818655 and is fully insured. We’re rated 5.0 stars on Google with over 200 reviews, A+ rated with the Better Business Bureau, and trusted by homeowners across Southwest Florida. We carry equipment from Daikin, Allied, and RunTru and maintain supplier relationships that let us offer competitive pricing on every installation.
