Had the best service for my A/c by your excellent technicians. They were super professional and fixed the problem in no time. Can't recommend enough. read more

I would like to say from the beginning, the service was outstanding. The whole system had to be replaced. It gave our family 26 good years. From Kelsey and Melanie answering the phones, making appointments, keeping track of the technicians, and the installers. Azarya: came to the door he was amazing, honest, smart, kind and very good at his job. The team: Omar, Henry, Juan Carlos, Renento and I'am sure there was another amazing hard working fella. What teamwork, precision and hard work. They got the unit and all of the duct work up and running. Thank You, There were a couple of other Techs and Team Leaders along the way: Geovanny, Edwardo, Raymond. Thank You, for your patience. Thank You JMS for your service. All The Best, Penny read more

My service with Raymond was top quality!! Not only was he right on time, but very easy to communicate with and definitely very full of knowledge. I will definitely use JMS in the future. Even the lady that originally took my call was very polite and professional! She helped me figure out what I needed, even though I didn't know exactly what I was talking about. read more

Absolutely abysmal customer service, I had not one but two service appointments rescheduled on me after wasting TWO five hour windows waiting for a technician. After being assured that on the 3rd appointment I would be the first stop of the technicians day, I called to find out his ETA only to find out he was 2 appointments away. Clearly these people dont care about their customers so do business with someone else read more

I had a truly disappointing experience with JMS Air Conditioning. Their scheduling was a nightmare, they insist on using phone calls to do business and often wouldn't answer when I'd call multiple times. They kept calling my property tenants instead of the landlord and sent a technician with nobody at the home because they couldn't communicate about scheduling. Their dispatch team is apparently new and doesn't know what they're doing. To make matters worse, there was zero communication upon arrival and during installation. They didn't bother to send photos or explain their actions. Literally just installed an entire system without indicatin when they were starting or who was on the property. Didn't ask to start or anything. The customer service and dispatch teams had shockingly bad attitudes, making the experience even more frustrating. Super sassy and rude. Their lack of professionalism was evident in every interaction. To top it all off, they charged an astronomical amount for the services provided, leaving me feeling completely ripped off. That said, this is the only service that responded out of 25 inquiries I sent around Los Angeles. A few others responded but couldn't even form a coherent sentence. Why is LA's air conditioning industry such garbage? read more

I was sold a Daiken mini split air conditioner and was assured that any mechanical issues would be covered by the ten year warranty... About 6 months later the unit took a dump and after numerous attempts by their serviceman to fix it I was told that nothing could be done. Ultimately I was conned into purchasing another unit for just under what I had originally paid.. There are a few other details anyone is welcome to send me a message I would be happy to go into more depth. I want to make it clear that it is the owner who is unscrupulous and shady not the employees. read more

JMS sold me a 3 ton mini split with a 10 year warranty.. when the unit crapped out on me 6 months later they strung me along for weeks and weeks telling me that they were talking to manufacturer etc. In the end they charged me almost what a new unit would cost with a bs story about me having to pay them for the "time it took" dealing with Daiken to procure a new unit. I regret ever dealing with them. There are more details to this story anyone reading this who suspects there other factors is welcome to contact me and I will gladly fill in the blanks. read more

Enio L. Is such a professional. Explained everything (issues & resolutions) to me. Voiced my concerns to the office. Was prompt and very courteous. Good technicians at this company. They communicate arrival time pretty well also. read more

The driver of this van/truck was tailgating us and honking for no reason. He was a hazard to me and other drivers. This was on the 10 Fwy, exiting at Overland today, 6/13/204. I would not trust this tech on the road and certainly not in my home. This company needs to check their techs/service people as they represent your business. read more

Advance notice informing of arrival time. Very thorough, very tidy. Friendly and courteous.

I had a mini split installed by JMS in 2019 and it recently stopped working. I called to have them come out and check on it. After the first visit, they said it was an electrical issue and they would send someone who could work on that. The next day, two people came, spent some time testing things, and came back to me confirming that it was an electrical issue somewhere under the house but that they couldn't fix it. After some back and forth we determined that JMS were the ones responsible for the electrical work in the first place so they said they'd send the person who installed it originally to come fix it. At that point, everything went downhill fast. I called in Tuesday afternoon, many hours after being told that I was a priority and they would call me when they had the electrician's availability and they said the dispatcher would call me later that day. Nothing. I called Wednesday morning and they said they'd call me back when they got availability from the electrician. Nothing. I called around lunch and they said the person working on my job was at lunch but would call me back. Nothing. I called mid afternoon and they said they would follow up by the end of the day for sure. Nothing. I called Thursday morning and they finally said the electrician would arrive in the afternoon. The electrician arrived and it was immediately clear that JMS had not communicated at all about what needed to happen. The electrician was not prepared to go under the house, was not prepared to run new wire, was not at all prepared for what I had discussed with JMS. I ended up having to pay the electrician hundreds of dollars out of my own pocket and went almost a week without heat in my house thanks to an epic failure to communicate. Two stars because the original install was just fine but this was one of the worst service experiences of my life and I will not be using the company again. read more

rip offs, unprofessional & double charged me and still hasn't given my money back. they're rude when trying to speak to them and they insist on knowing everything. my bank account states otherwise and I have proof and now no one will get back to me. read more

As per usual, JMS technician, Raymond, arrived as planned, maintained my unit, which is on a maintenance plan, changed the filter, and addressed a minor concern that I had. Always pleasant, always tidy, and it is nice to work with technicians that I have known for years! read more

Wow, was I duped. I had mini split systems installed in my duplex by JMS in 2019. At the time I thought it was a great job (though definitely not inexpensive). However, since then, we have had multiple problems with the units not working and had JMS out multiple times to fix the units. Over this past VERY HOT summer, the units stopped working multiple times and the service person always told my daughter it was user error or a circuit breaker. When one of the units started leaking freon, we insisted they properly identify the problem. They charged us $2700 for a leak detection service and told us they found 3 leaks in the lines. I asked what could have caused the leaks and they said the units just naturally vibrate. This is contrary to what other companies told me causes leaks in mini split units. Why would anyone buy these units if they just naturally leak? JMS told me it would be an additional $7500 to fix the leaks. After recovering from that price tag, I asked the owner for photos documenting the exact leak spots and for a substantial price reduction since he installed the system 4 years ago. He wouldn't take responsibility for his role in the leaks and tried to hold the photos hostage until I paid him. Needless to say, it was not a pleasant conversation. Why would he hold them hostage? I've never not paid a bill in my life! Anyway, I paid right then and there over the phone and he sent the photos. I called another company that was highly recommended on Yelp to take a look at the units. He said JMS's installation was "ugly" and that there was no insulation on the exterior lines as is required, causing them to prematurely deteriorate . But he couldn't tell me where the leaks were based on the photos. I asked JMS to mark the photos with the exact locations of the leaks. After all, I already paid a lot of money for the leak detection service. JMS refused my several requests by phone, texts and emails (although Tina, who answers the phone, was lovely). Clearly they didn't want to give me the information because (1) I would use a different company to fix the problem and (2) I would find out that the problem wasn't what they diagnosed. Finally I threatened legal action and to report JMS to the Contractors State Licensing Board. Only then did JMS send me the marked up photos. Lo and behold, there were no leaks in the lines, only faulty connectors to the system. The new hvac company fixed all the connectors, including adding insulation to the original wiring, and charged me $2435 for everything. I've tried to keep this review factual notwithstanding the emotional toll the 2 months of dealing with JMS took on me. I will simply add that this is not the first time JMS tried to charge me an extraordinary amount of money for a job that another company fixed at a fraction of JMS's quote. Save your money. Keep your blood pressure low. Find an honest hvac company. In my opinion, this is not one. read more

Enio was exceptionally thorough and concise with his work and explanations throughout his time at the job site

They are excellent. Both my parents and I use them to maintain our units. Their service is top notch. They are responsive and extremely knowledgeable. You get a huge bang for your buck with them. High value service company. read more

I have used JMS before and I will definitely use them again. Enio came and explained everything to me. He didn't try to encourage me to do any expensive testing. He was honest though and explained things that could come up in the future. As far as pricing I'm not sure because sure I've only used them so I don't have anything to compare it too. All in all great experience read more

Jeff and Omar were on time, knowledgeable, and professional. JMS have been servicing my home for years now and we are very happy with their work. Highly recommended! read more

Came home after power had been out for 24 hours at my house and the system wasn't working properly. I called and Juan Carlos was able to come the same day! He got it fixed and all is well. Thank you Juan Carlos and the JMS team. Really appreciate you all. read more

I'm happy for the opportunity to review Yaniv's service. In a word, impressed. Yaniv was able to quickly diagnose a long-standing hvac issue--inconsistant heating/air conditioning across different rooms. Yaniv quickly pinpointed that a poorly designed and installed venting system was to blame. Moreover, Yaniv knew exactly what modifications would resolve the issue. Yaniv's competence and technical skill were clearly evident. I can wholeheartedly recommend Yaniv and will request that he performs all future hvac service. read more

Raymond has always been the best tech we have ever had! Many years have passed and we are grateful for every visit, repair, maintenance, etc. read more

Jeff, technician from JMS was punctual, and discussed what, if any, problems we were having with our system.. then he did the required 6 month maintenance.. Highly recommend JMS read more

Yaniv A from JMS was very professional, and informative about all he was checking with our system. Smelled good too.

Excellent service with JMS, we have been using them for 7 years and have always been satisfied with their quality of service.

I am a preferred customer for JMS. 3 weeks ago a power surge fried my Mitsubishi ac circuit board and other components. I urgently needed JMS to diagnose and fix the problem. Despite some miscommunication at first, they diagnosed, ordered the replacement parts and fixed my Mitsubishi unit for my surgical suite quickly. Thank you Tina and Enio ( lead tech) for sorting out our problem. I have been a loyal customer for over 7 years. We have never had a problem until 3 weeks ago and fortunately JMS helped me sort it out quickly. read more

Very happy with the service that they gave. Yes, I would use them again. When they came out, they were very courteous. And helped out a lot.

I've been trying to get them to do a maintenance check on 2 separate occasions, 1st time dispatch didn't schedule it and failed to update me. 2nd time it was raining so they had to reschedule .....again dispatch didn't update/call or even text me! Each time I've had to take a day off from work. After my maintenance plan expires I probably won't renew. read more

I recently replaced my aging furnace with a two stage heat pump with JMS. While it took a little longer than I had anticipated, JMS ensured that the job was done right, with quality and couldn't be happier with the end results. Big thanks to Raymond for finalizing our setup! read more

I had Heating service done by Enio, he is very professional and officiant .Thank you.

The five stars are only for the technician that came today. Apparently those that installed the new system in the house this summer did not set up the thermostat properly. It was not set up for a heat pump and so the heat wouldn't turn on for the last few days. I think that was a pretty bad mistake and I'm glad today's tech figured it out but this never should have happened. read more

Omar and Jeff have been our regular service techs for quite some time now, part of the JMS team that takes care of us with twice annual visits. Today was the hottest day of the year so far, and I surely didn't expect to see them on a same day service call - I'd thought it may be a couple days due to the ferocity of the heat wave; yet they were able to come at near the beginning of the service window and were able to diagnose & replace the worn out capacitor within 45 minutes. The cost of replacement was well within reason and we got our AC back running at less expense than anticipated. Omar is obviously growing in knowledge and experience, we're glad he is part of the team caring for our needs. read more

I am so happy with the installation of my air conditioner/heater.Everyone works so hard in this company and they completely took care of me.Made sure things were done perfectly.I've waited over 30 years to replace my old air conditioner and heating system.It hasn't worked for that long.JM air conditioning and Heating put in everything brand new and cleaned my air ducts all in the same day.I wish I could remember everyone's name who works there.There was Manuel,Bella,Jorge,Yaniv.I would refer this company to everyone.I can feel the cool air now.I'm in Heaven.Thank you JM air Conditioning and Heating ,You are the BEST !

I've recently contacted this company and spoke to Marco to get AC services and replace my thermostat. They came and did inspection and gave me a quote to put a google nest thermostat and installation for $525. So prior to my appointment, I've learned that LADWP has a AC optimization program where they'll install a google nest thermostat and labor for FREE!!! Mind you!! JMS is one of the participating company that appeared in the LADWP website. Upon consulting with another provider... they said we qualified for a free thermostat and labor. So why did Marco from JMS failed to mention that LADWP was providing this service for free and was charging me $525??? When I called back to cancel my appointment , I respectfully asked why I wasn't told about the program , his only response was "I will cancel your appointment tomorrow. Dishonesty or Forgot they are involved with the program? read more

Jeff and Omar at JMS did such an incredible job. I needed a part and they drove very far to pick it up and stayed late for me. All this so I didn't have to spend another night without AC. They were beyond sweet and JMS is very lucky to have them as part of the team.I wouldn't use anyone else. read more

I really love this company. I have been searching for a new HVAC service and was interested in the Preferred Customer Club, which offers a 2x yearly servicing for a set price. Yaniv was the best and he checked more things in my split unit than the guy our condo association was using. Janiv was very thorough and kept things clean and tidy. I have recommended JMS and Yaniv to all my neighbors. This is great value and quality, which these days is somewhat unusual. read more

Great service, great technician, on time. I will continue with JMS but with Jeff V as my service technician. He explains procedures with precision. Always willing to answer questions. Always friendly. And last but not least, he leaves my house spotless. Thank you Jeff read more

JMS has been servicing our AC/heating system since they installed it years ago. We really like the technicians who come to our home. Eduardo is especially great as he really knows our system well now and we really trust him. But every technician who has come to our house has been so nice and polite. They will suggest things to buy and explain why--which is just a common part of a business and can be helpful; and, importantly, they are always respectful of our choices--never a hard sell. A few months ago, I had a problem with our bill but was ultimately very pleased with the way Tina fixed everything and made things right to make up for my frustration. Mistakes happen but a good company is resolves it satisfactorily, which they did. We will continue to be loyal customers. read more

Service requested was perfectly met. The technician is very knowledgeable and excellent.
