Semper Fi did a great job diagnosing and fixing our water heater. They took great care to do the job right and even advised my tenant how to take better care of the hvac system for greater longevity. They were very prompt, and even came out on the weekend.

I recently used SEMPER fi to replace my water heater, and Jonathon was great! He demonstrated professionalism and handled the replacement competently, even though the confined space made the task a bit more challenging than usual. Jonathon’s attitude was positive throughout the process, which made the experience smooth. Highly recommended!

I didn’t wind up needing the repair, but when I reached out at 7pm letting them know I had a new baby and my AC was out, they replied within minutes and offered to come out that night. I was impressed by how thoughtful team was!
