Isaiah did a great job flushing out my hot water heater. He was personable and professional while pointing out the reasons I needed to consider replacing my 18 yo unit. $49 was a great deal imo. I’d use Semper Fi again. ⭐️⭐️⭐️⭐️⭐️

They answered the phone on a holiday weekend, had a tech onsite in a few hours, brought in a temporary solution for the night and had people replacing the system the next day.

Same day service, technician was out to the house quick and diagnosed the problem. Within a few hours I had 2 technicians show up with all new equipment and started doing a whole system change. They stayed until the job was finished. Victor and Jason were very dedicated to ensuring the job was done correctly. So far a great experience with semper fi!

Brandon and Andrew were wonderful workers. They were extremely caring from the moment they came into my house till they left. They took time to make sure our unit was working at tip top shape and completely explained how my A/C works. They took before and after pictures of the places they worked on and were very proactive with Cleaning. As a senior on a fixed income the price for the tune up was extremely affordable. I cannot express how thankful I am to Brandon and Andrew for their mindfulness and honesty through this appointment. They are truly valued team members. Thank you Semper Fi for putting veterans/ military families first.
