I can’t say enough about Semperfi. Years ago, I actually did air-conditioning and refrigeration. I’ve installed mini split AC systems at 74. Not something I’m gonna do now. Calling Semperfi was the best thing I could’ve done. It started with a free service of the AC. It ended the way I thought it would with needing a new one. They gave me a flat quote and even though they were here way longer than they expected and i think did more duct work than expected never added a dime. They also have a quality control person who comes out the next day to make sure that everything is the way they want it. He found some things that he really would like them to have changed and so they came out again, spent another three hours changing all those things. The new system works so much better than the old one even when the old one was working perfectly. I couldn’t be happier

I had a new HVAC / heat pump system installed. I was very impressed with the quality of the system , professionalism and cleanup. Financing was complex , but Stephanie and Chris were very helpful with discounts for being a first responder. My new system is very energy efficient. I am saving $ and have a great warranty. I have used Semper Fi for many years and recommend them to everyone.

Christian came out to diagnose our unit emergently and was able to provide it with a clean bill of health, recommending that we source a new thermostat as our Google nest was out of date. We will get that squared away. He was kind, courteous, and highly knowledgeable. 10/10

Had them over for maintenance on my cooler which "included" cleaning my coils, not charging me separate for what should be part of maintainence.I was shown before and after pics of what was done,which was a first and very appreciated. Turns out I also needed a quick start replaced and added a surge protector. This was done in a timely manner with clear explanations. I will definitely use this company again!! Thanks for the great service!!

Shared the real truth about my aging (21+) that endures the heat of Arizona. I knew the “free inspection” would lead to a list of items to consider, including replacement; similar to the car dealership offering at-cost oil changes to get me into the service center do they can hand me a laundry list of service items for my long-lasting Toyota. And of course, he offered a solution - a replacement, which I did not buy on the spot. I’m a researcher and not an impulse buyer. However, I’ll consider this company when the time comes because the sales person/tech did not push and came across as authentic.

Had my new thermostat go completely black on me after being only 7 months old. AC was stuck on, but it was blowing warmer air. Called Semper-Fi who installed it originally, and they were quick to get people out who stayed late into the night to get it fixed for me. Great customer service and great response time.
