Dylan did a fantastic job with our plumbing inspection today! He was super thorough, flushed our tankless water heater, and clearly explained a few upcoming maintenance needs. He also walked us through the membership options and helped set us up without any pressure. Highly recommend!

I had a great experience with Semper Fi Heating and Cooling replacing my 21-year-old AC heat pump system. The installation was a big job, including a crane to move the outdoor units, and I appreciated the crew’s hard work. They tested both heating and cooling, and a supervisor followed up the next day to review the installation.
As a Gulf War veteran, I especially appreciated the military discount. It made a meaningful difference on a major home expense, and their support for veterans means a lot to me.
The new system is cooling my home really well, and I’m very happy with the results. Thank you to the installation crew and everyone involved!

Dillon came out to flush our 15yr old water heater and was very thorough with explaining his concerns and recommendations working on a older unit. We are working towards replacing the water heater and a/c split system we have and will be highly considering Dillon and Semper Fi. Thanks again.

The tech Garrette still came threw, knocked lightly as to not wakes us just in case, thn got the job done in a blink. I was actually excited that the work ws done so quickly & it's still flowing smoothly!

I noticed i had leaking underneath my water heater and coincidentally they had reached out for a flush. They moved up the appointment earlier to accommodate the urgency. Michael and Patrick came by and were very friendly and informative. Once we decided a repair was necessary they had a spare water heater in the back of their van, they went straight away to switch out the old water heater and were finished before I even knew it. This company has preciously helped with my hvac system and each time its been a great experience. Theyre knowledgeable and leave the place better than they found it. Will always be choosing Semper Fi!!!

Shaheed is my technician, very professional and respectful, he found the damage in my air-condition and gave me all options for repairs. Shaheed addressed my concerns in regard to priorities in different scenarios, he explained me that semper fi have different options of credits in case of running low on budget and that was very helpful specially for situation like mine, my A/C stop working at the beginning of the holidays, YES!!! I don't think nobody wants to hear that, so!!! be always ready have a plan before something like that happen to you. Either way my call was done early in the morning today and I thought that I will have to the weekend to get a technician, but NO, they called me with an early appointment between 10 and 1pm and they made it at 11:30 super-fast for me.
Thank you, SEMPER FI.
