The entire team was very professional & courteous. And, although unusually busy with other customers the day of installation, we're determined to get our new a/c unit installed. I would most definitely, recommend Semper Fi Heating & Cooling. read more

I just had a tune-up on my AC unit this afternoon. I was so pleased with the service. They gave me the heads up that they might be 15-30 min late- very thoughtful. The rep was friendly and efficient. He didn't try to unnecessarily sell me on anything, he was very informative and gave me recommendations on how to maintain my unit and what to do over the next few years. His recommendations were reasonable and helpful. I will definitely be using them moving forward. They did not ask for me to write a review either, I felt compelled based on the poor reviews I saw initially and the very contrarily outstanding service I received. 10/10 read more

We had a very frustrating experience with Semper Fi Heating & Cooling. They came out to diagnose our AC and ultimately sold us on a full system replacement for over $11,000. After installation, the system is still not working properly, and despite multiple attempts to contact them, we have not received timely follow-up service to resolve the issue. Living in Arizona, a functioning AC system is not optional, and being left without proper cooling after spending that kind of money is unacceptable. What's most disappointing is not just the initial issue, but the lack of responsiveness afterward. When you invest in a major system like this, you expect reliable support if something isn't right. At this point, we are still waiting for the problem to be corrected. read more

had a brand new AC unit put in in 2023 anytime the thermostat adjusts the AC stops had the technicians out and They can't find anything wrong. I have had the yearly maintenance done on the AC unit told the tech that anytime I adjust the AC thermostat the unit stops working, we shut off the unit for 3-4 hours then turn it back on, here we are May 2026 the same issue the air conditioner stoped working, it sounds like it's on but no cold air; 81 degrees in the house. The AC unit is so unreliable we have put portable air conditioners in every single bedroom in our house. They are sending a technician out on Tuesday, May 12 so maybe I will have a better review. read more

A new Company after our old company sold out to folks from Utah...They failed real fast. today we had 2 great Vets take care of our plumbing plan and one repair. Excellent guys and service. read more

They got out to my property very quickly to fix my AC. They were so efficient and made sure to give me any educational information that I needed to keep my system running smooth. read more

Called this company after seeing an ad on Instagram. $59 service. Their service man Chad came out and after running a check on both my AC units he gave me an estimate for basic recommended service of $1650. Partial recommended service of $5845 full recommended service $7164. Didn't like his attitude as he seemed to get upset when I said, I wanted to think about it. Then said he could subtract the service fee off if I did it today. I said no, and at that point, he seemed upset and left. It seems their mission is to just upsell you for whatever they can. Wouldn't recommend this company at all. read more

Don't do it!!!! I'm so disappointed that this company presents itself as a vet-owned, honorable company- they are not. I came across Semper Fi on a Facebook ad- I saw the promo for a tune up for $50. I thought it would be good to do that and I liked that it was a veteran company, my dad had been in the service. Before the appointment even happened, I received a text saying that if I referred them to someone and they buy a new unit, they would give a $250 gift card to me. I found that odd and in poor taste, but I kept the appointment. I should've paid attention to the first red flag. The representative showed up around 6pm- again, odd. How can you properly see what you're doing in the dark...? The first thing this guy starts talking about when he comes in the house is their financing for new AC units- why are we talking about that when YOU HAVEN'T EVEN LOOKED AT MY AC YET...? Because that is what they do, all they are trying to do is sell you a new AC. Scammer BS -fear tactics- complete waste of my time and money. I was told all these things were wrong, repairs would be $3k or that a midrange unit replacement would be $17k - without ductwork. Absolutely ridiculous. You guys should be ASHAMED of yourselves. Seriously. I had Westland Mechanical come out a couple days later- Absolutely NOTHING wrong with the unit. A couple of maintenance items to take care of, but nothing like what I had been told. Give Westland a call, they are actually HONEST. read more

Semper Fi Heating & Cooling - Help us scam someone you know!!! - Heating & Air Conditioning/HVAC Near Me - Phoenix, Arizona

Our technician Luke was very respectful and professional, he explained our maintenance report and educated my husband on the process. Amazing service! read more

Semper Fi was amazing. They came out on time and were responsive. I'd highly recommend and plan on using them again.

Called to set a time for a/c service. The Tech did the service, then proceeded to try to sell me a new unit. Since my system was no longer a spring chicken, I said I would consider it. I also said, when I do, I'll call 3 vendors to bid. Found out if I didn't order now he wouldn't get any credit for the sale. I like to work with companies whose techs are TECHS and not SALESPEOPLE. read more

I purchased a new AC unit from Semper Fi last July and yesterday, it started blowing semi-cold air, would not shut off and the indoor temp rose to 79 degrees. I did not think I'd be able to get someone out until Monday; but they really came through. Julian was here in a little over an hour and within minutes, the unit was running great. Not sure what the issue was; but he gave me his phone number to call if I had any problems. You could tell that he is a hard worker and very conscientious. I would highly recommend Semper Fi Heating and Cooling! read more

Don't trust these people. Absolute joke. Had a free consult after them messaging me for years. Made it clear that I was NOT interested in new units at this time. Quoted me 63k for 2 units and insulation. An absolute joke. Also, when will sales people realize that it's a red flag when they say, "I'm honest, I'm not like the other guys." Lol read more

I just want to be clear that this review applies to all valley locations. It is not specific to this location. The techs are dispatched based on their current area assignments. Most calls and communications I receive seem to come from a central location in Phoenix. We have been looking for a new HVAC maintenance company. We saw Semper Fi at a booth at the home show, and decided to give them an opportunity to look at our system and see if they might be a good option. We had been with a competitor for a number of years and were not satisfied with the constant attempts to scare us into buying services and parts we didn't need. We chose Semper Fi and one other company besides our existing company to come and do an end-of-summer tune-up. I was shocked and disappointed that Semper Fi was the absolute worst for trying to scare us into upsells. They concluded with 3 proposals, the last being replacing the whole HVAC system!!! Even our current company never went that far. As for value, if you want to be scared into buying things you don't need, I suggest either calling them, or going to a mechanic in AJ. There was zero value in this tune-up. Honestly, the third company that I had never heard of did the best job by far. read more

Be very wary of this company. Came out to offer a free inspection, ran down numbers and explained thoroughly why they wanted close to $25,000.00 for 2 units. Had another ac company come out and determined that freon had leaked out due to a loose valve. Feel as if Semper Fi had my unit stop working in order to earn my business. The sales rep or tech also called back a few days later and was very aggressive in his sales tactics. I am a veteran and am very disappointed in their business model. Heads up to anyone in need of an AC unite replacement but unless something changed recently there are much better companies in the valley that operate with integrity. read more

In my opinion, Semper Fi is a TOTAL SCAM!!! They say they offer a FREE AC Tuneup. When they get to your house, it is a NON-STOP up sell for a new AC unit. There is NO tuneup and it was one of the WORST experiences I have ever had with an AC company. I finally had to kick the tech, Shawn, off my property for continuing to argue with me about my AC unit and the lack of an AC tuneup. While some people MAY of had a positive experience with this company, I am NOT one of them. Total manipulation!! By the way, I texted the company about my experience, and surprise surprise, NO RESPONSE......... read more

Sketchy upsells. Told me I had all these issues and a 2nd opinion stated otherwise. It's a shame companies rely on these tactics. Never gain

Update: We had an install manager out today who was very helpful. It does look like the roofing issue may have been due time and weather, looking at before install and after install pictures. I still believe it would be helpful to have a roofing person on staff to approve large roof installs to avoid issues like this, but that is just my two cents. Ultimately, the manager was very helpful and is offering some vent and duct cleaning and adjustments to help offset the costs of our roof issues. We are very pleased that management listened to us and worked with us to make the issue right. Still deducting 1 start for how it was originally handled and somewhat pushy sales, otherwise we are content. Original: I am so bummed to be writing this review, but buckle up, here we go. 1st and foremost, go through the 1 start reviews when choosing this company. In 2022 we had a new AC installed on our roof at the cost of over $12,000. Fast forward to two weeks ago, during the heavy rains we had in the valley water was pouring behind our wall and out an outlet. When we went to explore what was going on, we discovered that the wood under our AC is severely water damaged and you can see daylight coming through where the AC is installed. We only discovered the issue, because of the heavy rains we experienced. We have had two people come out from Semper Fi, both technicians, both fairly dismissive. The second guy also let us know that apparently there are issues with our ductwork and venting and that would need to be fixed at the cost of $3600 or Semper Fi would potentially void our warranty on our AC. Semper Fi has stated repeatedly that the roofing issue was a PREEXISTING issue, one that was never disclosed to us prior to the installation. We would have NEVER installed on a damaged roof or with damaged hardware. Same thing with this ductwork, it was never disclosed to us at the time of installation. At this point we feel it was not disclosed to push a fast sale! We have had both an insurance adjuster and a roofer come out who both confirm the issue is due to faulty installation. So, we are sitting here with thousands of dollars of damage and instead of sending out someone who has the capacity (management or higher) to actually make it right, they try to get us to pay $3600 for more work that was never disclosed to us. We are a veteran Marine family who chose this company based on what we thought would be ethical conduct and integrity in business dealings. That has not been the case and we are severely disappointed. read more

My technician was friendly and answered all my questions. Josh was very good. Once again Semper Fi..

Had a rough go of it at first with difficulty getting the technicians here within the window provided. It is never about how great a company is when things are perfect it's about execution when things don't go as planned. Absolutely fantastic experience and will use them yearly for all maintenance and buy a new HVAC when the time comes. Jason installed a new water heater and filtration system and I could not be happier. Excellent work and great full for their professionalism. read more

They did what initially appeared to be a thorough review of the condo and our needs. We need a larger AC unit and they told us we could fit a much larger unit and quoted that. The price went down 3 times while we were shopping AC companies. Turns out they are only interested in turn and burn sales and do not care about getting it right. Steer clear if you care about quality. read more

Requested a AC service through Yelp and Semper Fi Heating & Cooling was one of the companies that got back to me. They made a great offer for an AC service, asked many questions, which I all answered, and when it came to scheduling the service, I was told that they could service the AC in January 2026, which was three months later at the time. Why would this not get shared immediately? Waste of time. No idea how the work would have been. Never made it to it. read more

Came early. Quick service to replace our leaking water heater. Incredibly overpriced from other quotes but had to get it done today. They do give military discount which was so respectful. read more

We had James P come out today to service our AC Unit. He was very friendly. He explained to us what was wrong with our unit and the options we could do to get our unit fixed. He didn't try and sell us something we didn't need and that showed us he was looking out for us the customer. I would recommend him and Semper Fi to everyone who reads this comment. And Thanks again James for your outstanding service. read more

This is the second time I have done business with Semper Fi and I thought to myself both times has been a professional and pleasant experience that I needed to mention it. I had a new AC unit installed last spring. Everything went smoothly and quickly. The installers were clean, professional, and friendly. This morning I had a plumber out for water heater flushing service. The plumber was on time, clean, professional, and explained the process to me. We had conversation about other things of interest to us both. It was a pleasant experience. Nice way to start the day. I recommend Semper Fi Heating Cooling And Plumbing services. read more

Yesterday morning our gas water heater went out. It was relatively new; about 3 years old and still under warranty. We called the original installation plumbing company but they couldn't get to us for about 3 days. Then I called our preferred private plumber but they too couldn't get to us immediately. The heater was a Bradford White unit so I called them for a recommendation. They gave me the number for Semper Fi, one of their preferred and certified contractors. I called Semper Fi and they were able to give me a same day commitment for service at 3 pm yesterday. Their tech, Eric, called and showed up at 1 pm, 2 hours earlier than committed. He sourced a new replacement heater and was done with the installation by 5 pm. He was fast, courteous, efficient, and competent. I was impressed! Even for this emergency replacement, I thought their pricing for service and labor was fair. Hence the 5 star rating. read more

I have been more than patient with this company. They had 4 opportunities, yes 4, to fix my A/C unit and it still doesn't work properly. They added some bogus gadgets that apparently do nothing. So, over $2000 later, here I am with the same problems. Stay away from Semper Fi, it's a scam! read more

Definitely recommend Sempre Fi. Craig came out and repaired and replaced a blown motor. We had a couple hiccups.However, in the end, everything was done, as was promised. I'm happy read more

We have had nothing but trouble since we trusted Sempre FI. The website promises complete customer satisfaction. I cannot say that has been our experience. Do not fall for the ratings they claim. We have had to have 4 service calls since they installed new AC units this past April. The fourth call revealed that our system was incorrectly installed. The technician found so many mistakes that he could not even believe it. There has been undo stress on these units because of the incompetence of the installation team. I was told that those who installed our units have all been let go. That did not make me feel any better. I have attempted to get a call from the owner to discuss concerns about what was done to our units due to the stress put on them while they were running incorrectly. NO RESPONSE. This has been our experience. There is a very long list to what we have gone through that is not a show of excellence on this company's part. I cannot in good conscience not share this experience. read more
