Semper Fi Heating and Cooling

Semper Fi Heating and Cooling works out of Mesa, TX with a clear focus on plumbing services for both homes and businesses. The crew handles everyday pipe repairs, drain clearing, and water line fixes while also managing heating and cooling equipment when those systems tie into the plumbing work. Local conditions in Texas mean they stay ready for calls about hard water buildup, leaking fixtures, and sewer backups that hit during heavy rains or dry spells. They cover the area with straightforward service that keeps water flowing without unnecessary delays or upsells.

Plumbers in Mesa, TX regularly tackle jobs like replacing old water heaters before they fail in summer heat, rerouting pipes around foundation shifts common in the local clay soil, and fixing irrigation leaks that waste water during long dry periods. Homeowners often deal with low pressure from mineral deposits or sudden clogs in kitchen lines from grease and debris buildup. This outfit moves in with basic tools and parts on the truck to handle most calls in one visit, checking joints and valves thoroughly before wrapping up so the same problem does not return weeks later. They also install new fixtures and run gas lines for appliances when needed, working around existing HVAC setups without tearing up finished walls.

Customers keep coming back because the work holds up under daily use and the crew explains options in plain terms before starting. They show up on time, keep the site tidy, and stick to quoted prices even when extra steps come up during the job. Speed and quality stand out across the feedback, along with clear updates that prevent surprises. DIRT Score 4.78 from 12765 reviews on Finds.

“Semper Fi replaced our AC’s two years ago. We had two 5-ton variable speed AC’s installed and what a game changer that was. Massive drop on our electric bill and our house is consistently cool. We just had Semper Fi out to install a two ton mini-split in our garage. They responded super quick, their price was better than everyone else we checked with, and the install was super fast and clean. I should have pulled the trigger on a mini-split years ago. Our garage is 72 degrees now. If you’re a vet, like me, Semper Fi can’t be beat. Semper Fi!”

“Our ac unit was over 20 years old- and last summer was the worst we've ever dealt with. During the hot months, it was between 95 and 103 degrees INSIDE the house!! We bought a portable swamp cooler just to get some relief- it only helped a little. Our dogs didn't even have the energy to bark at noises outside. This year we decided we couldn't go thru that again and called up Semper Fi due to hearing they had a discount for military families. We had our ac replaced in May. The whole process was fairly simple and the person we dealt with was extremely knowledgeable!! ( We even had a "skylight" for a little bit LOL). The process of installing our new unit went very easy as well. I would definitely recommend Semper Fi Heating and Cooling!!”

“I had a fantastic experience from start to finish with my new AC installation. It all started with Jourdan, who made the sales process seamless and ensured I got exactly what I needed without any pressure. The installation itself was top-notch. Alex Rodriguez and Manny did an incredible job. They were professional, efficient, and clearly experts at their craft. They took the time to make sure everything and left the workplace spotless. If you’re looking for a team that actually cares about quality work, ask for these guys!”

“My old unit was Forty One years old. My buddy from high school was an hvac guy and he kept it going and taught me how to work one it each time it needed service. Each morning I would open the bathroom window and listen for any issues. Once every year or two I would service it. Ten years ago Semper Fi had an oldest A/C contest...I should have win then, and we would chat about "time yet?" I would tell them "Still icy cold". Last Wednesday the heat quit working and after 41 years I decided not to get on the roof again. Called Semper Fi on Saturday and they could get an estimator over same day. We negotiated on the unit and heat elements and he said they could install it Monday two days later. Really professional installers, perfect install, works perfect. I am VERY impressed.

“My A/C gave out after 15 years—something I knew was coming since I bought my house two years ago. Unfortunately, it happened the day I got home from a work trip, in the middle of July in Arizona. I had another company come out first, but they couldn't get someone to my house to provide a replacement quote until Monday. Since this all happened on a Friday, waiting several more days without A/C wasn't an option. I called Semper Fi Heating & Cooling, and they had someone out almost immediately. Colin was absolutely fantastic. As a single woman, inviting someone into your home for a major purchase can feel intimidating, but Colin immediately made me feel comfortable. He never came across as pushy or like he was just trying to make a sale. Instead, he took the time to understand what made sen”

“Brad was excellent to work with. The install went exceptionally smooth, and your installers were helpful! I tried out the AC last night and the house was cool in no time. Highly recommend working with Semper Fi”

“I can’t say enough good things about Semper Fi Heating & Cooling! From the very first interaction, their communication was second to none — absolutely fantastic. Every person I spoke with was professional, friendly, and genuinely focused on helping us find the best solution for our needs. They took the time to listen, answered all of our questions, and provided clear options in a timely manner. The service itself was lightning fast — I was truly impressed by how quickly everything moved from estimate to completion. The quality of the work speaks for itself. The installation was done with care and attention to detail, and the team treated our home with respect throughout the entire process. What really stood out was the consistency across the entire company. From the office staff on the ”

“*UPDATE* After talking with managers Nick and Jacob who moved mountains for me and my family. We are getting a brand new AC unit today (7/11/26). Me and my family appreciate all the hard work and tough decision making that Semper Fi has to go through. I’d recommend Semper Fi heating and cooling to anyone with HVAC issues without hesitation! Again, thank you Semper Fi team for being there for me and my family. Had my A/C unit replaced by them June of 2025. Well, here we are 13 months later and my Unit that costs me a car payment every month doesn’t work. Their remedy for me, my wife, brother in law, 4 kids, and 4 dogs was 1 portable ac unit for 1 bedroom. (Which smells like sewage when in use) and not insulate around the exhaust going out the window which makes the thing more of an he”

“When I first called SemperFi Heating and Cooling, I was a bit anxious. But, when I spoke to the amazing dispatcher, all my stress was immediately gone. The service was absolutely amazing, some of the best I’ve ever experienced in a long time. A big thank you to the dispatcher, Brianna Flores. It was a pleasure to have her. My technician came on time, figured out the issue quickly, and swiftly took care of it while keeping me informed on it all. My ac works better than ever now! I definitely recommend SemperFi heating and cooling for their great and reliable service, very knowledgeable technicians, and exceptional customer service. Thank you, Brianna, for making sure I’m not stressed the whole way!”

“I am so impressed with the service I received from Semper Fi and the technician Brandon M. My experience was phenomenal in how professional, knowledgable as well as courteous that Brandon was.I also was so impressed with his genuinely caring attitude in diagnosing the issues! Brandon also meticulously installed a new ecobee thermostat that I provided. No pressure to buy thermostat from Semper Fi. I had hundreds of questions and Brandon took the time to answer each of them. Based on my experience, I will be using Semper Fi as my go to HVAC company for repair and maintenance. When I need a new System; I will be using Semper Fi and Brandon M. will definitely be my “go to” technician. I should also mention that he did a complimentary very thorough inspection and tune up of my 2 Trane- 5 ton ”
