I want to thank Semper FI , for help me my AC & heater . I want to say thank you to Joey. He was really good very nice. He helped me and it was a good price. It wasn’t bad at all when I was priced from other places more than what it was , and that was crazy because of that I could not have my AC fixed. And I’m able to pay it in payments .
Thank you Semper FI ,
Thank you Semper FI ,

Isaac and Matthew were AMAZING!! Professional, informative on every aspect of our install. The weight of the cost being disabled is difficult, but the guys actually lifted the burden somewhat in how they performed. The kindness showed to my wife Kiki was so appreciated. Not only will we recommend Semper Fi to everyone in need, we'd only have Isaac and Matthew personally service our system needs (hopefully not, lol). I'm an American Navy Corpsman (vet.), and the discount overall was a great deal. These two young men were a blessing to our home, truly sent by our Lord, sincerely, V. Craig & Kiki Johnson

This is an update on Tuesday 20 Oct 2026, we found after opening our home and breaking bread, a full meal, that Matthew was only playing the "Christian" card, in order to sign us up for a system cost that was not only unnecessary, but drove our costs to over 10k. We told Matthew our situation of both being disabled, and fiscal limitations, asking for a unit to be best cost effective to our budget. Right there he'd the opportunity to be truthful, but instead chose the proverbial flim-flam/okie doke route. We had to ask my Mother to assist us credit wise, because of my credit score being just south of Semper Fi's requirements. And because Matthew didn't do right by us. In retrospect review, we could have had installed a unit for more than 3-4k less, but because of Matthew's clearly dishonest machinations, we again had to finance, which because of, disqualified us for the in-motion refinancing which would have taken our mortgage payment down 1,500k!! A 2.5 apr point swing!, in addition had three payments eliminated at new rate. Now to some that nay not seem much, but to fixed income folks, especially in this economy is huge. Because I'm a sinner saved by Grace, when someone professes Jesus Christ as "their Savior", I at face have to believe them. In addition if Matthew is what he professed, he left that rode knowingly and willingly for personal gain...self, and I'll leave it to Yahweh to deal with. I don't know the commission($) he gets from Semper Fi, and or the finance company, that would encourage his behavior, or that he's simply playing folks for selfish gain, but I here warn people on dealing with a company that encourages or allows this type of "service", knowing people, especially veterans use "veteran owned" companies because of the said companies seemingly "patriotic" code of ethics, honesty, trust and respect for our veteran men and women's, time served. And not just for military, but people in general. It's taken me awhile to repost, because I've reached out to Semper Fi, but nothing...nada, even to taking accountability for it's employees (Matthew's) actions. We ended up here, because of our bought and paid for "home warranty" company too stiffed us come replacement/repair time. There was a time when doing right, affording true customer service meant something in our Republic. But those times are woefully...gone. Whom you choose for this type of is obviously up to you, but I'd urge one to think twice about Semper Fi, they talk a great game, but at the end of the battle?, you realize you're by yourself in the foxhole, and have from first shot fired. I pray for everyone who's been through, or are in the midst of...regardless the company. Have a blessed day everyone!

OOh-Rah! New Customer for Life here! It was a relief to know this Veteran Owned company exists! HONEST, PERSONABLE, AND RELIABLE. Semper Fi's Plumber Donald P. was super efficient! I noticed their VAN on the road and took down the number, as I needed 2 toilet bowls replaced. As a recent widow of our National Asset David Henderson who succumbed to toxic exposure and protected our freedoms for 35 years, I've been overwhelmed with anything house related that my late Navy Veteran Husband would have handled. Donald was courteous, clean - wore boot protectors in the house-, engaged with his office on my behalf, and really went above and beyond seamlessly. Super pleased and would highly recommend, especially when I have been duped in the recent past with a prior plumber whereas their workers took my warranty sticker, and used it, off my hot water heater! Yeah, ...that happened! (Lic # 0093216). Nevertheless, my business is now with Semper Fi who covers a multitude of home repair services! Hang onto that Donald P. Semper Fi! -- Donald P. is who one envisions to represent the company name! Never Quit!~

Mason Baughn came to check out my water heater and found there was a small leak that had developed. He explained everything to me very well and I agreed to have it replaced with an American maid, hot water heater. He was very professional and cleaned everything up nicely.
