Finally!! No b.s.! Johnny and Ivan were very proficient in determining the status of my old system and different options for a new unit. Installation was completed in a timely manner. Clean, courteous, and professional. I would HIGHLY recommend Semper Fidelis AC for any HVAC needs!

They are extremely professional and courteous. Ivan, was fantastic. He did the diagnostics on our AC system and showed me where the problem was located. Ordered the parts after quoting me the price. Highly recommend this company. Thank you

Johnny and his crew were awesome. They were professional and respectful of our home. They took the time to explain our options and helped us pick the best system for our home. Being veterans as well we wanted to support a veteran owned business and they did not disappoint. I highly recommend Semper Fi for all AC needs or questions. They had us up and running with a full install in 1 day. Here's a little before and after photo session. Our home was built in October 2024, the AC unit installed was less than a year old with no drip pan. We are beyond happy with our new unit. Thank you Johnny and crew!

The Owner Jonny and his son ivan
Are definitely the best Heating and Cooling company in Southwest Florida. I have delt with several other companies in the past 24 years and have total trust in this company. They had the difficult job of removing and reinstalling a new AC system in my condo in Fiddlers Creek. Everything was explained to me and my son and the unit was perfectly installed. Please consider using this veteran and son. They are excellent technicians and very honest. Thank you
