Semper Fi Heating & Cooling is a veteran-run HVAC & plumbing company built on the values of service, integrity, and always being there when you need us.

Tech was courteous, prompt, and very knowledgeable.

The kid Edward was very nice, and he did his job correctly, I was very satisfied with that. Thank you.

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was able to provide it with a clean bill of health, recommending that we source a new thermostat as our Google nest was out of date.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

Always professional and reliable every time I need them

The service tech (Storm) went beyond the call of duty . Stayed late to finish the job. Excellent work.

Best company we’ve had out in years

Marty and Steve were great in doing my install. Very knowledgeable and personable.😊

Rachel was awesome very knowledgeable in her field excellent communication skills thanks for all your help!

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!!

Excellent customer service along with the installation

Tony and Dominic were very kind and helpful swapping out my thermostat.

David was very professional and detailed. Very pleasurable experience

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.

Great job very friendly and thorough service walked us through everything and made sure we understood everything

Colin did a great job reviewing the needs of both our systems and price is great and wife and i will discuss on completing this estimate for repairs and new unit

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.

Aaron was great! On time service, insightful assessment, professional, respectful of property, and friendly. Looking forward to working with him again.
