Semper Fi came out to confirm an HVAC diagnosis and I couldn't be more impressed. The technician was knowledgeable, thorough, and authorized to price everything on the spot -- no back-and-forth with a salesman. He walked me through multiple options and came in with extremely competitive pricing. The install crew was just as professional -- efficient, courteous, and left the place spotless. The whole job took over 11 hours and you'd never know they were here. One week in and the system runs quietly and efficiently. Highly recommend! read more

Do not use Semper Fi for your HVAC needs. It's ironic that when you call, you're greeted with, "How can I make you smile today?" Unfortunately, there has been nothing about our experience with this company that would make anyone smile. We had a brand-new AC unit installed in July 2025. Everything appeared to be working properly until June 2026, when we noticed the system was running almost constantly while struggling to cool our home. After reviewing data from our Ecobee thermostat, I discovered the unit was running nearly 20 hours per day and still could not lower the temperature below 81 degrees. We contacted Semper Fi, and to their credit, they sent a technician out the following day. However, the technician's conclusion was that we needed additional ductwork and another air intake because the larger unit they installed required more airflow than our previous system. The obvious question--which went unanswered--was: Why wasn't this identified and addressed during the original installation 11 months earlier? Not convinced that airflow alone explained the problem, I sought a second opinion from another HVAC company. While they agreed that an additional intake would be beneficial, they also discovered a refrigerant leak and found the system was nearly out of refrigerant. According to them, this was the primary reason the unit was unable to cool the house. What followed was even more frustrating. It took approximately ten additional phone calls, extended hold times of up to 45 minutes, and even dropped calls before Semper Fi finally arranged for someone to come assess the issue. Most recently, we were given a service window of 7:00-9:00 a.m. The technician never arrived and no one called. After we contacted the company again, we were told someone would be there between 1:00-3:00 p.m. That appointment was missed as well. At this point, we are left with a relatively new AC unit that is not functioning properly, a refrigerant leak that should not exist in a system less than a year old, and a company that appears unwilling or unable to communicate effectively or take ownership of the situation. Semper Fi needs to address the problems created by their installation and provide the level of service and accountability customers should expect after spending thousands of dollars on a new HVAC system. read more

We have used Semper Fi twice in the past couple of years. We used them for an AC tune-up, which was great. Recently, we had Garrett come out to do our hot water heater flush & plumbing check. Garrett was amazing! He was really friendly, explained things thoroughly, and checked out our faucets and fridge water. I appreciate how kind he was and he knew all the answers to our questions. I highly recommend them for the San Tan Valley area! read more

Customer service was good when they needed to sell me an ac unit. Came recommended by friends and gave a vet discount for my husband's prior service. Install teams were very nice. But, had to call them twice to get them to come out and fix the new unit being so loud. They came to fix it and left a huge hole in my drywall for over a month. Made 3 phone calls to have the drywall repaired and it still isn't fixed. $14k for a new AC seems steep when they have customer service gaps like this... read more

We got wonderful customer service, without feeling "pushed." Although purchasing 2 A/C units gave us severe sticker shock, they came in below 2 other bids. The installation took all day, but they were professional and efficient. read more

Really impressed with the whole experience. Scheduling was quick and easy, and the woman I spoke with in the office was genuinely kind and helpful. Andre came out for the service call and was fantastic -- punctual, professional, knowledgeable, and efficient. Everything was handled smoothly, with great communication and zero hassle. Solid company, great people, highly recommend. read more

They came out for $70 to do a diagnostic. They told me that I had a bad capacitor. They also tried to sell me a new unit. I took the capacitors to Grainger for bench testing, no problem! So I paid $70 for a misdiagnosis and now they refuse to refund my money. read more

Worst customer service I ever received from a contractor. Tech was here 2 days ago, assessed the problem, and I ordered the service. Since then they have not returned my 4 phone calls regarding the parts they were supposed to order. They promised to give me a temporary solution which they also did not do. I had to call and cancel my service. So now in 110 heat I have to wait even longer because I need to call another company. read more

Yesterday Isaak Castaneda came out to do a cleaning and checkup of our units. He explained the process to us then go strate to work. He preformed all his tasks in a timely manner answered every question we had. The whole experience was pleasant and informative. I have and will still recommend Semper Fi to my friends and family. But Isaak was a breath of fresh air with his great aditude and knowledge. read more

I honestly wish I could leave a Zero star or even negative stars for this business of scam artists!!! We had one a/c unit go out and called them to come out because it was about 8pm. The technician came named Jason, who did all the checking up in the attic and on the unit. Told me he had bad news, our unit was 12 years old and the part we need will take a month and half to come in, because you know, it's such an old unit. That part was priced around $6000. But he could also jimmy rig our system for now that would cost around $1400 but we had to sign a waiver because doing this could break other things on the unit. Jason recommended that replacement was the best option because they could squeeze us in Monday and they would give us portable units to get us through the weekend. Price tag of $22,000!!! BUT then we are looking at the other unit burning out so replacing both would be ideal with a price tag of $34,000. We said we needed to think about it, his tune sure changed and he started pulling discounts out of thin air, even an employee discount mind you!!! After we stated again we would need a second opinion, he got really upset and said I can see you don't trust me.....I mean you are a perfect stranger in our home that we met an hour ago, so why wouldn't we trust you. We said no, he left. We have an ac guy that tunes our units up twice a year and just did it in May, but he had been out of town. He came over the next day and found what was wrong. He replaced the part for $45!!!!! But along the way, he said he was trying to figure out what this tech did because something was off. Well after two hours of investigating he found that our outside unit had been tampered with and wiring in the attic was also sabotaged by Jason. This is something we regular non HVAC people wouldn't know and wouldn't be able to figure out. Do the math of $34,000 compared to $45 and I think you will chose wisely before you call these guys. Whats really sad is that they pride themselves on honoring our veterans....what better way to do that than to scam every customer out of THOUSANDS of dollars!!! I hope this reaches someone who is not in the market to be scammed either, do NOT use this company!!! read more

Shame on this company for trying to scam my elderly disabled parents by messing with their ac units! Not only did they try to sell them unnecessary things but the tech did something to their a/c without their knowledge and another company had to come out and fix it!!! AVOID THIS COMPANY AT ALL COSTS!! read more

Semper fi sent the first repairman to my home and told me I needed a new outside unit for $3,500. I questioned this as my house was under 5 years old. Semper fi apologized and sent a second repair man who recommended a $900 upgrade to me system. I called in a different hvac company, chas roberts and all I needed was a $70.00 compassion. Semper fi is a rip out company. A very dishonest company. read more

Had a new ac unit installed and it never worked, they had to come out to my house 7 times and finally refused to come back out. I eventually had to hire another company to come out and they took 15 minutes to tell me that one of the parts on the brand new unit was bad and had it up and running in under an hour. They had the absolute worst install techs and customer service I have ever seen. I will never trust this company again. read more

We had a salesperson come the house to quote a new ac system. they quoted us two systems, and we chose the one we could afford. It was quoted everything as a system that had everything outside. Included in the quote was free duct cleaning and a electronic filter. when they came to install everything, it was a split system. So, no air filter and they said because the duct cleaning was not on the invoice, it was not included. None of this was mentioned to us. They chose to change the order and no update Som be careful if you choose them to do work. 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

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

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

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

I had a regular maintenance check done 6/25/26. To start with, Tech left my air at 62 after leaving my house about 6:45pm. It ran all night. I have no trust left with this company, every time I get a different tech who try's to upsell me & tells me the part they are trying to get me to buy will only last another 6months or so. There is no prep for the encounter on their part, I had the part he recommended to be replaced soon replaced the last maintenance visit. When I told the tech this, he said it's really b/c another part was needed. I will never use them again, if I can't trust a company, there is no reason to use them 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

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.

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

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

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

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

NEVER AGAIN--would I use Semper Fe heating and cooling. Management is absolutely ruthless and duplicitous. I would not pay balance till my project was done. Their worker was instructed to remove the power relay in the newly installed A/C unit (thereby no A/C to my home) since I would not zero balance my account with them. This created a health risk from the excess heat in my home. Paid off the balance when other aspects of project were completed and they returned to me the handle to the power box. Multiple days later my system was restored! Probably paid more than other companies for this work. read more

Great company that I would recommend to any one!!!!..The Professionalism, knowledge and skill of the Sales person, Office Staff and installers of our new HVAC system are great!!!.. read more

$1300 for a warranty swap after a 20% discount? Water heater less than 3 years old! Never again with this company. We will be replacing our HVAC with someone else! Your loss and you can bet I will spread the word in our community! Also asked for a detailed bill got just the amount we paid! Terrible! 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

The technician came, assessed the unit and diagnosed it as a motor fan replacement. He took the initial payment to order the part and we never heard back from him or Semper Fi. We called and texted for an eta and received nothing. After 8 days we called another company and they came out to look at the system. Turns out is was a capacitor only and the semper Fi technician was trying to upsell. Very disappointed. Trying to get our deposit back now. When I called they informed me that the part was ready as of yesterday but didn't communicate that with me in any way. 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

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

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

Zamir arrived on time, was very efficient & professional & still personable. He answered all my questions and offered info on some of their other services. I did not feel pressured & appreciated his taking the time to inform me of services that would help my unit last longer in this AZ climate. read more

There were promises made that weren't delivered on, and the overall quality of my equipment is not what I expected. We replaced a 25+ year old Trane system with York equipment at the suggestion of Semper Fi. They took my old Thermostats off and put in another brand. I had a great Honeywell wifi thermostat and it was easy to use and reliable. They replaced it with horrible Ecobee brand (don't buy!!). We're still struggling trying to figure those out. Also, the York is twice as loud through the wall as the Trane, and our cooling bill is dramatically higher. (Yes, it was a hotter May than last year, but not this same % of increase). They were supposed to balance the airflow in some of our bedrooms and they remain hot. While lots of promises have been made, it didn't work out the way that we were hoping. We paid Trane prices for York equipment and a song and dance . . . They promised an extended warranty that never arrived. Sadly, I'm wishing we had gone another route and I encourage you to look carefully at your suppliers and your preferred brands before using these guys, or buy from them when they aren't so busy that they can't deliver on what you need. 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

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
