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. ⭐️⭐️⭐️⭐️⭐️

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.

I was initially drawn to Semper Fi because I am a Marine. I became a return customer based on their prompt excellent service and fair pricing! I have purchased three A/C systems from Semper Fi and a large Hot Water Heater. They provide free service and maintenance for those units.
Make Semper Fi your first choice for your home. I will.

This is the second time we have used Semper Fi, this time for a water heater replacement. Andrew was meticulously in the removal, installation and final walk through of the replacement with us. We highly recommend Semper Fi for HVAC & plumbing.

Semper Fi was amazing to work with for our AC service and ultimately replacement. Rafael came out within the 8-11am window, thoroughly inspected the unit inside and outside and made recommendations based on our immediate needs and weighed our options to repair or replace. We ultimately went with repair and we have a crew coming out to replace our unit. If you need service, repair or replacement, we wholeheartedly recommend Semper Fi.
