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

I purchased a brand-new HVAC unit from this company approximately one month ago for $13,500, and unfortunately, the system has already stopped working multiple times. After the first time the unit stopped working (two weeks after installation) we waited 48 hours for a technician to come out. The technician advised us that the drainage lines were clogged and debris needed to be cleared. Though these drainage lines were supposed to be completely cleared during the installation process. The technician quickly blew out the drainage lines and said the problem was resolved. However, the unit is now not working again (one month after installation and two weeks since it stopped working the first time), which is very concerning for such a new and costly system. As customers we want to have assurances that the technicians and the company are properly resolving issues. I called the warranty line first thing this morning and was told that no one could come out until tomorrow evening. Because this has become an ongoing issue, we requested to speak with a supervisor. The supervisor refused to speak with us, the overall lack of response has left us feeling undervalued as customers. After investing this much money in a brand-new system, we expected reliable performance and more urgent support when repeated problems occurred so soon after installation. At this point, we are concerned that this issue may continue to happen and that the underlying problem has not been fully resolved. We are very disappointed with both the reliability of the new unit and the customer service we have received. We hope the company takes this situation seriously, provides a lasting solution, and improves communication and support for customers dealing with repeated system failures. 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

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

DO NOT USE THIS COMPANY. I should have done way more research before booking with this company. Lesson learned. It was late in the day and AC went out and the first two companies I called did not have same day availabilty. Our AC is only five years old and has been running wiht no issues since we bought our home a year and a half ago. Semper shows up and after poking around and looking like he is working he says a circuit or wire needed repairing. Of course we say go ahead. This was $386 dollars. THen he proceeds to tell my husband that we need an antirely new AC unit that this is going out and this is going out and so on. I got emailed 3 invoices for brand new units from 11-14K. Let me remind you, 5 year old AC and the unit going out pretty sure was some small faulty wiring that was a super simple fix. After digesting and reviewing the invoices for a brand new AC I reached out to another company for a second opinion especialyl since I always get 2 or 3 bids for anything. They came out next day and first off cannot find any work that is appears the guy did the day before. He did a full second opinion on our unit and diagnostic. He could find NOTHING wrong after doing a full inspection. Not could he see any work done the day before on anything. He did show us the capacitor was running low and said it could go any day or run fine into next year and showed us what could be fixed and gave his recomendation. I also reached out for an itemized list of the work done by Semper and I get one line invoice with circuit repair. Where is my breakdown if labor and parts, etc. They also roped my into their $12 monthly service with 25% dicount on all work. That was also a lie as my invoice has only 20% and I am cancelling this with the company. So a possible faulty wire that probably was not real cost over $400. Now my AC did start back up but I lost money and they have no integrity. Please do not make my mistake and call someone else. read more

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

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

Who wouldn't want to support a Vet owned business?! The responsiveness is amazing! Great customer service!

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

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

One of the worst customer service experiences we have ever had. They were real quick to get us to buy a new AC Unit for almost $20,000 with a 10 year warranty. Well, 11 days later the board was fried and we have now been without AC in the Arizona heat for almost 20 days. Daily calls have been made to them with the constant "oh we will get back to you" or "we don't have an update yet". I never get a call back. I have requested a manager or supervisor to assist us as we have pets and children in our home and still have not received any assistance. We continue to suffer with no AC (other than a 1200 BTU portable unit). I would NOT recommend this company. 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

My brother and his family used this company and they came replaced the a/c, left when they were done and its not working. He called back to let them know and they said they couldn't fix for a week! Hello..its 100+ degrees outside. They have kids and an elderly person. What kind od business you running! DO NOT USE THIS COMPANY! THEY ARE A JOKE!​ read more

Carlos was very pleasant and very kind and he took great care to make sure I understood what he was doing and why. I would recommend and use Semper Fi going forward. My experience was awesome. read more

I had my new AC installed less than two months ago. They said my AC submits a signal to them and they will know if something is wrong with my AC before I do. On 7/23/26 My unit started having issues and is not cooling my house. They had no clue. I called and they said someone will be out the following monday. is now 1:35 on Monday. I called again and they said next Monday. Two weeks with bad air in Arizona with an AC. Bad customer service. 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

My brand new unit is broken in less than 2 years and I cannot get service to fix it, I even had an appointment scheduled and not only did they not show up, they never called to let me know they were not coming. In addition, after new install I had to make 3 additional service calls to remove a loud noise in the vents, that noise is now back. I am completely unhappy with the product quality and service. I am a very reasonable person and this is unacceptable. How would you feel if your brand new unit stopped after less than 2 years??? We have been living in a home that is 98 degrees for 3 days now. I am so sorry I choose this company for my air conditioner. 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

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

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

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

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

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

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

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

$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

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

bought a new AC less than 3 yrs ago. 1 1/2 yrs later cooling intermittently, had to replace parts.2 1/2 yrs now not cooling. tech tried to tell me it's because my ducts were dirty. rechecked and found Bad board. Had to wait a week for board. Different tech puts in board and says another part is bad also. First tech did catch it. no one calls me on the part or an update. I have to call every couple days. Part doesn't come in. after a week the part comes in but no one called me. Says someone will call me to schedule. 2 nd day no one calls. . I call again and tell them . I've been waiting for this part for nine days now. Finally someone calls me and tells me I have to wait another week for them to be available to come out and put the part in. I tell them I've already taken a day off work and I can't take another day off and all she can say is well the best we can do. They have poor communication, you leave messages and nobody calls you and every time you call is, how can I make you smile today which is a joke should not have this many issues on a new HVAC. My old one lasted 23 years and never went down on me. frustrated 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

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

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

Our 5 year old unit stopped working last Friday, 7/24 and we contacted Semper Fi. We were told that the soonest they could have someone look at it would be Sunday 7/26. The tech came on Sunday and told us that he was able to diagnose the problem but unable to fix it. He explained that there were only a few techs that could do this repair and that they would need to order the part. My husband made multiple calls to the office on Monday to try to get a timeline and only received one after hours of follow up phone calls. On Wednesday, 7/29 a different tech arrived to fix the unit. Once the repair was finished the alarm on our thermostat continued to go off. The tech explained that the repair was done but that now the compressor was blown. At this point we are 5 days into to this unit being down during an excessive heat warning. I spoke with someone from their office that evening that was very condescending and told me that he would update me on Thurs. 7/30. My updates yesterday only said that it takes 24 hours to get a ETA on the part and that once they know I will know. By the end of the day the temperature in my home is in the 90's. It is now Friday 7/31 and we are more than 24 hours from the time I was told the part was ordered and I have heard nothing. We have spent over $400 on a portable unit to attempt to make the house bearable. With temps reaching up to 116 this weekend and no communication or action from Semper Fi I am left beyond frustrated. If you are looking for a company with a sense of urgency during the hot summer months you should consider doing business with another company. read more

One of the worst companies across any speciality that I have ever had the displeasure of dealing with. This really starts in 2022 when I was upsold a system. At install, the unit was off-center, the lines were not insulated, and the attic was left a mess, with McDonald's trash just left there. Unsurprisingly, the entire thing failed less than a year later. In July. After a few days, they finally caved and decided to replace the entire system under warranty. That was 2023. Now to July 2026. AC went down on a Thursday night. Technician came Friday morning and told me the control board was bad. The part "could" be ordered that day, but I would get a call on status later that day, but if not, a status would be provided on Monday. Well, I call them later on Friday, at 3:22 PM to be exact. I got the "After Hours Call Center". 3 PM is after hours? They don't order parts on weekends (nor do they seem to do anything else). Monday rolls around and I call for status on my part. Parts and warranty folk don't start until 8ish or 9ish, no one knows for sure. I am told notes will be put in and someone will reach out. By noon, no one has reached out. I call again. This disgrace of a customer service rep is named Courtney. I am told the part ordering is "in process" but no other information. No part number, no status, no ETA, nothing. "We don't order parts on weekends" she tells me. I ask kindly for a supervisor. "I can't do that" she says. I ask if she even works for Semper Fi or just a call center they outsource. She yells to me "I am in the Mesa office, sir. I am staring at Jesse's office right now!" I assume she means the founder, Jesse Keenan. So I ask her to go get him then. Wave him over to your desk and get him on the phone. Or any other supervisor or manager. She still "can't do that". So I say I will come down to the office myself to speak to him. She says I can't do that and proceeds to hang up on me. So I head down to their building in Mesa. I walk in and it is worse than expected. Nothing but rows of cubicles with people on phones yelling and announcing up-sales and large profits. Announcements about revenue and sales and targets throughout. No real customer service. I tell the guy at the front desk I just want a status on my part and at least an estimated date to do the work so I can go home again. After several minutes around the corner, he comes back to tell me they have the part in the warehouse and can have someone out Tuesday. Strange to get that right up front after several days and calls with nothing. In any case, I head home to take a gander at the thing myself. I found the manual online and troubleshooting steps. From the Friday tech's details, I start to wonder if they even have the right part that needs replacing. So I call another HVAC company to take a look. Yep, it's the drive board (Semper Fi said control" board). So maybe SF is on the right track, so I'll wait for Tuesday. So after multiple statements that someone would reach out to me, and no one ever had, I was surprised to receive a call from SF at 9:23 PM Tuesday night. It was to tell me that they wanted to push my Tuesday appt to Thursday. Their "warranty supervisor" was going to be out for "the next day or so." This is unacceptable, that would be a week without AC with no info or help and now this? I tell them I am going to use a different company, as the level of service and lack of care, response, details, everything was enough. I say cancel it all. Imagine my surprise again when a tech shows up at 8 AM on Tuesday with a plethora of parts. I tell him that his services would not be needed, as I am going with another company. I call their phone bank again to say I don't need anything from them ever again. They sent ANOTHER tech this morning, Thursday. Another lack of communication. They are nothing but sleazy salespeople and folks that would rather ring their sales bell than help a customer. As a Marine myself, I am ashamed the founder is one and dragging their motto through the mud for his own gain at the expense of others, specifically veterans. 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..

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
