I purchased my Ac unit from Semper 3 years ago. I have always recieved excellent service from office and service department. Recently I noticed that the AC was not cooling so I called the service department expecting a week or more wait time to have my account looked at. Much to my surprise Semper Fi offered to come out within a couple of hours from my call. Being that it was after 6pm when I called I was surprised because it was after hours since I scheduled for the following day. The tech was at my house early and got my ac cooling again. A part had to be order so I'm thinking great I will be out of service for a week. To my surprise the service tech was back the next day and installed the new motor. Both the tech and business staff were professionals and provided excellent customer service. I couldn't be happier with Semper Fi and would highly recommend them for all services they provide. As a matter if fact, I just recommend a family member for a new ac. Thank you Semper Fi for the EXCELLENT CUSTER SERVICE YOU PROVIDE. read more

This was our first time in using Semper Fi. We had been using another company in the past. So glad we found Semper Fi. Daniel was superb! He took his time in looking at our AC unit and explained everything that was good/bad about our unit in terms that could we could understand. Semper Fi WILL be our choice in the future for all our needs. Thank you for having Daniel be a representative of your company! Mary Pusieski read more

I had my HVAC service today, by Connor. He was excellent in presentation and able to answer my questions in terms that I can understand. I would highly recommend Connor for any service you may need in the HVAC. Connor goes above and beyond. Semper Fi is very fortunate to have an employee on their staff. Thank you Connor for your excellent work. read more

Sadly I did purchase a Heat Pump AC HVAC from Semper Fi last March, 2025. This year of 2026 i was seeing lots of sites that stated "one can find out what the cost of a HVAC system will cost & I could research what I purchased would cost:. I had gotten a BOSCH 18 seer 5Ton heat pump package. Semper Fi's contract indicated the package would be $36,544. BUT they would give me a discount & charge me $24,408. which I had paid off by the middle of December 2025. Semper Fi has had lots of advertisements the past several months saying "look up products & pricing . So I did research BOSCH with it's product code & number & the price is $9,378 & in my zip code $9,196. & the 5 Ton is 1 ton too big for my 1460 square foot home. Even adding the price of the guys to install the HVAC, the crane service say another $800. The BOSCH ought to have cost around $10,000. Also, Semper Fi provided 2 different thermostats which did not function because the humidity in my home stayed around 58% to 65% when it was only 19% outside (in Phoenix). I did get the correct & current thermostat at Amazon for my new 2025 BOSCH unit & did have Semper Fi install it...but it took from July 24 to November 19, 2025 of twelve (12), yes 12 service guys to come to my home & figure out how to adjust the HVAC system for my 1460 square foot home....totally oversized as I had a 3.5 ton previously !! So, be very careful with Semper Fi as they overcharged me $14,408. Then again, perhaps the oversights were taking advantage of a white haired woman senior. I asked questions & my concerns were not addressed obviously Semper Fi wanted the sale. I also did not use their loan company as their 15.99 percentage fee was for ten (10) years. Thankfully I had my savings. And, even with having a 10 (ten) year warranty I will always search for the sale coupon of $17.75. I did file a complaint with the BBB & ROC From Debra P read more

Person who booked our appointment was deceptive. We ended up paying for something we didn't need and didn't get the service we asked for.

Would leave 0 stars if I could. Had a technician come out for a tune-up. Took one look at my system and said that the whole unit, which is only 6 years old, needs to be replaced for a 5-figure amount. He also left the compressor unplugged after he left. I'm glad I found it and fixed the issue or else it would have really looked like my AC unit was broken and needed replacing. Can't really believe that this was an accident. I called another business and they replaced a $30 part, fixed a leak, and topped off my coolant all for a few hundred dollars instead of the entire replacement which was over $10k. Please listen to me when I say that I would avoid these dishonest people like the plague. Now they won't stop hounding me for the $50 I owe for the tune-up even though they left my unit in a bad shape. Go anywhere else. read more

Called them out for a pre summer A/C inspection for $17.75. They came out promptly and checked everything out. I had no issues and they didn't try any unnecessary up-sales. I will use them again. read more

Do not use this company. This company had a promotional ad on social media for a free tuneup on my AC Units so I scheduled an appointment but I should have known it was too good to be true. I didn't receive a tuneup but an inspection which I did not schedule for. Later in the day I received an email for $99 invoice for the service. I contacted the company and informed them on the promotional ad on social media but they didn't acknowledge the promotion. P.S The technician was very respectful and professional. The company alone is terrible read more

Semper Fi came into our 4 year old home. They told us we needed a completely new A/C unit. That ours was installed incorrectly by the builder and never registered for it's warranty. The temps are rising into the 100's so we hired them to install the new A/C unit. They were here ALL day the next day for the installation. In the attic and the back yard installing all the new things with a 10 year warranty for $20,000! And that was with my 20% discount for being a first responder!! 3 weeks later the fan stopped working on the brand new outside unit. We called Semper Fi, letting them know it's 78-80 degrees in the house. They came out the next day. Diagnosed the burnt out fan. Day 3 with no A/C they scheduled to come out between 10-2, later called and said 1-4, then called and said 1-8pm. Then called at 5pm saying they aren't coming at all but we are on the schedule to be rescheduled!?!?!?!?!?!?!!!!! We tried to call to speak to a manager with no luck. You can't get ahold of anyone at Semper Fi. Only a large call center that handles multiple companies calls. So at least ANOTHER day with no A/C! It was 109 today!! We feel financially taken advantage of and dismissed. They were quick to come out for our initial visit and now that they got our money/business we and put at the back of the line. BEWARE!!! Get a second opinion, that was our first mistake and then the guys that came to do the install said we didn't really need to replace everything and he didn't know why they suggested that in the first place and that he would talk to him. I just have no words for this company other than SCAMMERS!! What a misrepresentation of Semper Fi!! WOW!! read more

ABSOLUTE SCAM... BEWARE! From someone in the housing industry, it is ridiculous and disappointing also. From their website it states clearly that they are offering a service for TUNE UP for $17.75, which is what was requested to prepare our unit for the summer and make sure it is working optimally. After a series of text messages, was told that they do not do preventative maintenance but to try back in October. See attached and don't waste your time or money with this company!!

Semper Fi Heating & Cooling - page 1 of texts - Heating & Air Conditioning/HVAC Near Me - Mesa, Arizona

See all

I filed my complaint with the BBB and ROC after spending 13k+ and still having issues with a new purchase.

I have called Semper Fi twice for service. One time for a maintenance visit and this second time to replace our evap coil. Jordan came to evaluate the situation and confirmed the coil needed to be replaced and took a video of it to show what it was doing in our attic. When he called to check on the replacement part, he was told they might have one the following Monday, and this was on a Thursday. He called me later that Thursday afternoon to let me know he kept looking and found the part for me and could have it installed the next day. The next day, it was installed earlier than initially anticipated, which was great, and our A/C is working great. read more

I signed up for the service plan (monthly fee). It comes with a couple of checks of the HVAC and a water heater flush. These were fine. I just got tired of being scared to death *literally*every*time someone came by and gave me the Imminent Doom Warning and corresponding $400-$800+ in Something Dire Estimate. Each time I got a second opinion, and each time I was told "yeah that's a good upgrade if you have the cash just laying around, but "need? ...no." or similar. Like... they didn't do anything wrong and the men were always very respectful, clean, you can't ask for more in that dept. But my anxiety is WAY too high already than to be paralyzed with paranoia and stress over what is now about 6 or 7 Ominous Portents along the lines of "Could be REALLY bad and just so you know, your homeowners policy and home warranty won't cover that..." so I'm going to live dangerously I guess. read more

A few weeks ago, I called Semper Fi to check on my recently installed heater, and they sent a technician within an hour--excellent customer service. Because I'm an existing customer, they later sent a plumber, Garrett Linde, to drain and inspect my water heater for wear and tear. Garrett was professional, friendly, and very knowledgeable. He drained the tank, showed me the mineral deposits, and carefully inspected the unit. He clearly explained what needed attention and pointed out that the safety pressure valve should be replaced. Overall, I'm very impressed with Semper Fi and Garrett's work. Highly recommended! read more

Semper Fi Heating & Cooling is not just a bad company, they are outright crooks hiding behind a brand name that should mean integrity. What they pulled is nothing short of theft. They tried to rob me for over $1,100 to swap out two cheap capacitors that retail for under $40 each and take less than an hour of labor. That's not a "mistake," that's deliberate fraud. Their sham "rebates" and "discounts" are nothing but bait-and-switch tactics to cover up their highway robbery. And when I confronted them, they admitted to overcharging me and promised a refund. That admission is a confession, they know exactly what they're doing: ripping off hardworking people and hoping no one calls them on it. This company operates like a pack of vultures circling for their next victim. They prey on homeowners who may not know the true cost of parts and labor, and then line their pockets through predatory pricing and deception. It's disgraceful, it's unethical, and it's the very definition of fraud. If you want to set your money on fire, call Semper Fi. If you want honesty, professionalism, or basic decency, stay far away. They should be reported to the Better Business Bureau, consumer protection agencies, and every review site possible. Companies like this deserve to be exposed, blacklisted, and put out of business. Semper Fi Heating & Cooling is a scam operation. Dishonest, predatory, and completely untrustworthy. Avoid them like the plague. Do your research on them before pulling the trigger on anything they recommend to do on your unit. There are a numerous similar complaints. read more

Don't purchase anything from this company. I had a new AC installed a year ago and it's already inoperable. I've been trying to get it fixed for weeks, but it's one nightmare after the next. First tech came out, didn't do any real diagnostics just looked at a few things and said everything looks good. Called back the next day to say we're still having issues and they scheduled another tech who was a lot more interested in helping. He diagnosed the problem but said he will need to come back the next day to replace the part. When he arrived it was supposed to take about 2 hours, I didn't time it but it was closer to 5-6 hours, maybe longer. When he was done, he said there is another issue and they need to add an additional return vent which should have been done during initial installation and that someone would call me the following day to schedule. Meanwhile, he said I can't run the AC. I called at 8am to be proactive and was told someone would call me back, I called at 2pm again, still nothing, I called again at 4 and they said the same guy from yesterday will be coming back. The tech called me and let me know he will be by later (it was already 5:30pm) and I asked if we can put power back to the compressor so we can at least run some air through the house, he said it should be fine - guess what, the AC still doesn't work after the 5 hour repair. Mind you my AC worked fine for a year, all of a sudden it's just done. They either gave me a faulty unit, installed it incorrectly which caused irreparable damage or just don't know how to fix it. Might be time to contact BBB, AROC and whoever else can get something done about this. I also have an 18 month old that is sick, but they really don't care. Apparently there are other emergencies more important than mine. Please, please, please don't give this company your business! read more

As a Disabled Retired Veteran, I'm really disappointed at how much Semper Fi Heating and Cooling wanted to charge for A/C repair. After contacting a different company, we were charged only $981.68. Services A/C system repair Response from the owner 20 hours ago We're truly sorry to hear about your experience and want to make it right. Please call this direct line to speak with a manager: 480-915-0455. We'd love the opportunity to speak with you and make things right. I am totally shocked that a company who professes to represent the Marine motto contacted my Sister to discuss my review. As a Retired Army Sergeant Major,I would expect any company representing the Marines should know how an Army Sergeant Major would react to someone calling his Sister about a review he left! SHOCKING and DISAPPOINTED! read more

Review of UV Light Installation by Semper Fi Heating and Cooling I appreciated the prompt scheduling and the initial estimate process. However, I'm disappointed with the follow-through after the installation of the UV light sanitation device. Despite multiple follow-ups starting in May, I never received clear information about the specific product installed, its effectiveness, or how to maintain it long-term. For an $813 service, I expected more transparency and accountability--especially regarding warranty, replacement timelines, or performance specs like how many spores, mold particles, or airborne contaminants it removes. I only received vague product claims like "kills germs, bacteria, viruses, growth & odor" with no technical documentation. Additionally, I have not noticed any improvement in the air quality in my home since the installation. The reason I'm initiating this complaint is not just based on poor customer follow-up, but because I don't want anyone else in Sun Lakes to get taken advantage of by paying for a product without receiving proper documentation, support, or noticeable results. At this point, I believe a partial refund is warranted since I was not provided full product details or maintenance guidance. I hope this feedback helps Semper Fi improve its customer support and communication, especially when customers ask valid product questions before and after paying in full.

Sam was extremely knowledgeable, professional and polite working my husband on our water heater. He even got out his shop vac to clean up some drywall dust that was around the water heater just because he saw it there. Will be requesting him moving forward for any plumbing needs. Highly recommend! read more

I would NOT recommend these guys. My AC went out and so since I'm a supporter of the Marine Corps I put my trust into this company. The day of my scheduled appointment the guy shows up, very respectful. He looks and my AC tested one wire and says that my compressor is bad and it would cost me anywhere between $12K-$15K. Next morning a friend of mine gives me a number to another HVAC company, they come out and test my AC unit. Turns out that the compactor and moter went out. Simple fix. Paid less than $1K Labor and new parts read more

Emergency repair in the summer quick appointment no waiting for weeks for some other company to get an appointment, polite, punctuality, professional.

Your guys left dirt in my house, in my driveway, put the filter on backward, filled with freon then had to release the freon to turn the filter around the refill the freon. Damaged my custom paint in the bathroom access that cannot be matched. And gouged the walls that as well cannot be matched the paint to fix. So no I will not be referring. In fact you guys owe us at least $250 for the damages. My old air conditioner that was dying kept my house cooler than the brand new one. We have to run at 72 degrees all day to not sweat. My old dying air conditioner at 74 degrees we'd freeze. Not confidant installed correctly. It's only 85 degrees outside now. What's going to happen when it's 110 degrees. My utility bill doubled this month with the "new" air conditioner. Pretty pissed. read more

Very disappointed in semperfi. We ordered a new HVAC unit - $17,000! But ours (we were told by SemperFi) needed replaced. So we made an install appt. Guys arrived - unit wasn't going to fit in our attic. We were told we'd need a smaller one but it was comparable to the one we ordered except a single stage. But "still energy efficient." $15000... We just looked at the work. The unit is a made in China media. Horrible reviews on this product. In fact there is a class action law suit June 2025. I looked up my model number my unit (mcpm4860cn10th). Cash price: $1111.29. It appears SemperFi seriously over charged me. Unless the labor was nearly $14k. Find another HVAC company. read more

Do not trust a company that offers Amazon gift cards for a review. I cannot trust a company that uses those practices. My main reason for choosing this company, is because they're a veteran friendly business. As an army veteran, I am more open to giving a veteran owned or friendly company my business. Mainly because I expect them to operate with similar values, integrity, honest service and communication. My problem is with the technician from Semper Fi that came to my home. From the start, there was miscommunication as to why he was even at my home. The issue i was having, was the operation of my heater. It was blowing cool air. The technician didn't walk me through anything that he was doing, didn't check my filters, didn't check my thermostat. He went on my roof and spent about 15 -20 min up there. He came down, got a bag from his van, then went back up without telling me anything about what he was seeing or walking me through anything. He eventually came back down, gave me a price for a part that I would need and that was it. The lack of communication made me wary and lose trust. The 20 min he spent on my roof was suspect because of the way he was acting and then after giving the cost of repair, he got in his van and left. He wasn't friendly at all and just gave me shady vibes. As a customer, I should not feel uneasy and I should feel like I can totally trust the company and the tech for their expertise and not feel like I'm getting scammed. A technician is representing the company at all times. First impressions are everything and you only have one time to make a positive impression on a customer. If that trust is loss from the start and initial meeting, it's very difficult to get that back. Semper fi may be a great company but I will never know due to my own personal interaction with their employee who failed to represent the company in a professional manner. My advice, if you truly respect the people who have served our country, then you need to follow those same values. Respect Selfless service Honor Integrity Personal courage read more

Semper-Fi has us on a plan where they handle our maintenance twice a year. They've been great at finding issues and offering solutions. This year, our coil froze and cracked, and Semper-fi was there to give us options! Their financing saved us, and they're working on getting our AC working for us! They're always professional and they always let us know what the status is at all times. I never have to think about maintenance on my HVAC because they always call me twice a year to schedule. I know my system will always be in good shape because they ensure we're taken care of. Thanks Semper fi! read more

They showed up when they said they would. Respectful, professional and courteous. Highly recommend for any and all services.

After a late afternoon conversation, your technician arrived three hours later and quickly diagnosed the issue and got the air blowing cool air in less than ninety minutes. I would recommend Semper Fi to all my best friends. read more

My AC wasn't cooling and so their tech came to check and said has to do with the insulation and that the coils were dirty. He didn't mention anything about a part that was failing like another company did. He also didn't clean the coils good and so I had to pay for another company to clean it as the other company tech said the coil was still dirty after Semper Fi Tech cleaned it. The other company tech also said that the Semper Fi Tech has left trash behind on the roof. I had them install the insulation too and that work seems to be ok. read more

Addendum: Twice this year t=we set up a time for them to come to my house and clean my air conditioner for free. Twice they did NOT show up OR call. When i called they said they showed top and no one was home. That is not possible. I live in gated community and guards at gate have to write down who comes in. I told them so and they said the tech got delayed at the previous job. They changed story when confronted. We set up a new time frame. No one called or showed. Lied again and said someone called and I did not answer. I purposely stayed home to be at the house when they came. They text again and again to do the air conditioning check up. Why would they show up the third time?!! read more

I scheduled a free A/C tune-up with Semper Fi Heating & Cooling, expecting a routine maintenance check. Instead, the technician barely mentioned anything about tuning up my system and immediately launched into a sales pitch about energy loss and costly repairs. Before I knew it, he was pushing a $20,000+ system replacement, acting as if my current unit was on its last legs--despite no issues being noted in a previous visit. To make things worse, he even called someone to check on system availability, and the guy on the other end claimed they had only two units left after having 17 just two days ago--a classic high-pressure sales tactic that felt straight out of a sleazy car dealership. I called for a tune-up, not a sales pitch. If you're looking for honest service, I'd recommend looking elsewhere. read more

Awful Not 24/6 as billed and had to call twice to be told so. Poor front end customer service - how can you make me smile? Be honest when you tell me you'll call me back read more

Would leave zero stars if it was an option. Before looking at the unit, the technician stated that since it was old, we would be better off replacing it. Once he did his assessment, he told my husband it would be $600 to fix a fuse & wiring. When I joined the conversation, he said it would be at least $1000 to fix the fuse and wiring....the price estimate changed within minutes which immediately made me loose trust in him. He then began pushing a new unit on us & went into salesman mode. When asked a general estimate on the new unit, he quoted us $11,000. I told him that is a shocking price since we replaced our larger unit a few years prior for $8000, so how are we being quoted significantly more for a unit that is half the size? He wasn't able to give me a good answer & came off very defensive. Once he finished gathering his diagnostic supplies, he told my husband & I that his company does the best work which is why they may be more expensive. He stated that they don't cut corners & began justifying their significant cost difference from other companies with AC terms that went over my head. I asked him to please include those extra items you all replace when you send us the quote so when I make a decision, I can take those extras into consideration. He said those will not be in the estimate because it's just known. Long story short, if you are looking for a company that is not interested in fixing your unit, one that will aggressively push a new unit on you, give you an extremely high quote compared to other companies and get angry when you try to understand why the price is so high, then Semper Fi Heating & Cooling is what you have been searching for lol. read more

Vashawn our tech was very knowledgeable and his customer service is excellent. We highly recommend Semper Fi.

Disclaimer: this is a long and hopefully comprehensive review If you're interested in being egregiously overcharged and taken advantage of, this is the company for you. Additionally, if you're a veteran like myself be wary of the "20% discount", it's a hoax. They clearly don't care about veterans as the prices are sky high even with this so called "discount". I reached out to Semper Fi to do an annual inspection and that's when I met the technician, Tyler. Everything started off well as he appeared to be very personable and professional. However, after checking the capacitors (I have two units thus two capacitors) he stated that they both needed to be changed immediately. He said he was surprised that one of the two AC units was still operating as he's never seen a capacitor that bad. As we're currently in the middle of summer I took this very seriously. In addition he highly recommended getting two hard start kits installed as well. (I was upsold as I discussed with over AC companies/techs my current AC units didn't really benefit from that "upgrade") I foolishly agreed to the $1878.40 price tag with the "20% discount" which took off about $470 of made up inflated parts/labor costs. I thought at the time that these were expensive parts and that my AC units were going to shut off abruptly without the immediate service based off of what Tyler said. I also thought that the 20% discount was meant to really help veterans, I was mistaken. The overall service took about 45ish minutes which included a chemical wash/hose down of my AC units. Once Tyler left I remembered one of my friends worked at a AC parts distributor and I asked what he thought of the price tag. He just laughed and told me I got price gouged. Capacitors are $14.05 and hard start kits for my model are $49.95. The total is somewhere around $140 including tax. In reality I didn't need the two hard start kits so I could've just spent $30 on parts and done the service myself in probably 30-45 minutes after watching a YouTube video. It's really that easy... After realizing all of this I got some quotes from my distributor friend who knew a bunch of local companies. I realized a genuinely fair price for everything would've likely been in the $600-900 range for the work including the parts. I was outraged and felt taken advantage of for the reasons I stated before. I also thought they really cared about giving veterans a fair price with that discount, they don't. I ended up calling 4 days in a row trying to get a supervisor or someone to talk to and finally on day 4 I talked to someone. They gave me a small refund even after I showed them quotes from other businesses doing the exact same work at 1/2-1/3 the price. I guess I should be happy for getting any money back but the point of the story is do your own research and don't trust what these companies say you need or don't need. Semper Fi's technicians are very good at making you feel comfortable and seriously up-charging you on labor and parts you potentially don't need. Next time I'll pay the diagnostic fee watch a YouTube video buy the parts for $30 and save $1500+ for 30 minutes of work. Semper Fi will pray on your lack of knowledge about AC units, systems, parts, and labor prices. I would stay far away from this company. read more

Last tech 5stars , that serviced our heat-pump was a genius. Very polite and knowledgeable. The first tech 1star, sent out to check when it was just installed didn't know how to turn the unit back on after he shut it down to test. Way over priced ,1star salesman, and they sold us a heat-pump 4 ton rather than 3.5 as they had no 3.5ton units. SEER. Was very low at 15.2 and did NOT qualify for energy efficient unit . We are using 20% more electricity over previous TRANE. Current is American made in USA. Only reason we dropped $13029 for it. read more

Our service guy was very friendly, kind and knowledgeable! He explained everything really well... In fact, I told him in all the years that we have owned homes, and had companies come out, no one has ever explained the functionality of the components so well! My call was just for a service call because it hadn't been serviced in a couple years! And while nothing was broken, he did show us we had a couple couple components that were not working up to par as they should. The last thing you want is for your AC to break down in this terrible heat that we've been having! He did a great job!! read more
