After a lengthy discussion with the owner Yossi. We came to certain terms to appease both parties. I agreed to stay on with the membership with a mutual agreement to be open and discuss any future work in advance. Yossi is a reasonable and hard working business owner who strives to keep his team honest and customers satisfied. read more

I first used JMS to install new ducts, what a professional job! JMS next serviced my AC/heater and installed a new one when needed. I appreciated the on-site attention and information provided by seasoned personnel. read more

Unfortunately when our handyman installed The Nest thermostat he accidentally shorted out our air-conditioning unit. Fortunately, our neighbors recommended JMS! Communication through Emmy was efficient and lightning fast. She amazingly managed to send the awesome Eduardo and Sergio out same day. (I'm sure that's not always possible!) Eduardo and Sergio were true gentlemen and extremely knowledgeable. They (correctly) installed The Nest, fixed the short in the thermostat wiring and the short within the unit on the roof. I could not be more grateful for their quick help (let's be honest: rescue), kindness and clear communication. And a shout-out to Joe who helped get me to Emmy in the first place. I highly recommend JMS! read more

My experience with this company was beyond amazing!! They have great customer service, great quality products, and really helpful and fair with pricing. I originally called for some service to be done on my air conditioning unit and I had an extremely helpful employee come to my house to see the problem and tell me more about it. Yaniv explained the problem perfectly and routed me to a couple of different options to fix the issue. I ended up replacing the unit and the process was quick and clean. The executed the job perfectly, I really could not have asked for a better company to do it for me. Thank you so much!! read more

JMS installed a new air scrubber in my house and the tech, Yaniv, was very friendly and respectful. Will definitely refer this company!

Appreciated that the technician, Raymond, wore a mask and used good safe judgement during these Covid times! My husband said he was very professional, meticulous, checked all the parts carefully, and communicated everything along the way. Raymond was very courteous and polite. read more

Our thanks to JMS Air Conditioning and Heating Company for superior service and reliability. When our mini-split system stopped working, the company honored its warranty and replaced the broken unit. The technicians were highly skilled, very professional and extremely nice. They were respectful of our home, using booties over their shoes to keep the floors clean, and put down floor clothes when necessary. Joe, the owner, is a man of his word, was very concerned to make sure we were taken care of in a timely manner, and is such a nice man. We highly recommend using JMS for any H/AC needs. read more

the company is professional. a vendor for dwp optimization program. the technician Enio was kind and knowledgeable. the owner Joe was helpful when i needed something in writing. i highly recommend them. i will recommend them to family and friends. thanks read more

My moms heater went out and Damian came to the house and right from the start he was professional , incredibly knowledgeable about the heater , he was kind and that made the service so much more enjoyable. I recommend JMS very highly. They wasted no time in getting a technician out to us and they needed to order a part and in less than 24 hours moms heater was running great !! we will be using JMS again and even more than that I'm only requesting Damian to do all future maintenance services because he honestly was great at what he does but more importantly I know that were in the best hands possible to keep the heater in the best working condition and that's not easy because we live above the beach and the salt causes corrosion. if you have an issue with your heater or air conditioning JMS AIR Conditioning and Heating is the only company to call and request Damian you'll be in the best hands possible. read more

I was shopping for two replacement air conditioning/heating units. The air conditioning on my downstairs unit & the heat on my upstairs unit were not working. They were both around 48 years old. The basement ducting that supplies all three floors was also bad - broken in several places & disconnected from the ceiling vents, causing constant water leakage into the house during rain. Additionally, two large rooftop ducts lacked proper support, causing roof damage & more leaking. JMS's owner came & we agreed on a price for two high-efficiency units. I was pleasantly surprised that their technicians knew how to make roof repairs & the repairs were included in the job, which eliminated a major headache. Both installations were completed in 5-6 days and more technicians arrived to test the units & instruct me on their use. We had three powerful storms during the past two weeks, without a single drop of water leaking into the house. I was delighted to remove the 6 buckets that collected water in two rooms. I will be contacting JMS for replacement of a skylight in the near future. Initially, I didn't understand how to use the units efficiently & I was shutting the furnace off at night to avoid high utility bills. I mistakenly believed that whenever the units are on, they're using power, regardless of the thermostat setting. But JMS's technician explained that when the units are allowed to get very cold, they have to work much harder & longer to heat up the ducting in the cold basement before they can heat up the house. That turned out to be true; after the technician left, I used the units as he instructed & the entire house heated up nicely - including hallways where there were no vents. The owner came to check on the job after completion & also made some adjustments in the vents to improve air flow. A few weeks later, when one of the units malfunctioned, JMS immediately sent a very knowledgeable technician who quickly found the problem - rats had chewed on the wire in the basement that supplies power to the unit. Two skilled technicians came & replaced the entire length of wire & also encased it in rodent-proof covering. If you do business with JMS, you'll be very glad you did. read more

The owner, Yossi, is a really kind and professional man who follows up himself on the work they do. It is rare these days to come across such a dedicated person. At JMS, they do everything to make sure they give you the best possible experience. I highly recommend them. read more

My HVAC system was not heating at all. I called a highly recommended company that worked on fixing it for two days and they couldn't figure out what the problem was. I called another well-known HVAC company who also spent a day at my house and couldn't figure out what was wrong with my system. I finally called JMS HVAC. They scheduled the work and came out the same day I called. The service technician who diagnosed the problem said that I needed a new part. He ordered it and came back in a couple of days. (Supply chain issues) After installing the part and doing a tuneup, ​my system finally worked. From the lady who answered the phone, to the service technician who diagnosed the problem to the technician who installed the part​ and got my unit up and running, they were all polite, professional, careful, and were able to fix the problem that two other well-known companies couldn't figure out.​ Their price was very reasonable and I would recommend JMS to anyone with HVAC problems.​ read more

JMS was recommended to me as the "Gold Standard" to come in an fix what another company had done wrong. They were extremely competent and did the work quickly. They also did all the little details flawlessly and the team supervisor Gabriel even made a second trip back to check on something unrelated without charging us. The front office was very nice and professional with all of the billing, dispatch, etc. They weren't the lowest bidder (the first company was) but they were the best value by a mile. read more

I attempted to utilize JMS for the LADWP AC Tune Up program. I called and spoke to Angel, the dispatch manager. I requested their afternoon window and requested the last possible appointment (after 5PM) due to work commitments and he confirmed that we were good to go for 6PM on a selected date the following week. I called the morning of to confirm the afternoon appointment, again with Angel. He confirmed our agreement. I then got a call at 3 PM the day of the appointment, saying they were on their way to my home and would be there in a few minutes. I called and asked for Angel, in the midst of a very busy day, to inquire why he had left me a voicemail saying someone was on their way when just that morning, we had discussed the later time. He apologized and adjusted the schedule. The technician came, begrudgingly, at 6 PM. He was unable to access the roof due to not being able to reach anyone at my HOA to provide him with the access he needed, and we agreed to reschedule. I apologized for his inconvenience. I called and rescheduled for the following week, again with Angel. I asked for the same time frame, afternoon window, last available appointment. We confirmed. I received a confirmation call the night prior to the appointment, re-affirming our arrangement. Then this morning, the day of the appointment, I get a call from Angel, stating that someone is on their way to my house at 9:40 AM. I called back and asked for Angel and was told that due to LADWP requirements, the appointment must commence before 5 PM. I said that makes sense, however, I asked why this wasn't brought to my attention previously (for example, before the FIRST time the technicians came out) and furthermore, why this then lead to them unilaterally scheduling an appointment at 9:40 AM when we had already discussed and confirmed the afternoon. Lastly, why had HE had called me and left a voicemail telling me a technician was en route and then when I called in regards to said voicemail, he LIED and told me he had not called me and feigned ignorance. I told him I had listened to the voicemail (while the transcription I read aloud while on the phone wrongly called him Angela, it was actually Angel that called me minutes before) and it was HE who had called me, in addition to the fact that we had discussed this appointment and my timing preference in great detail. He maintained he didn't call me, even though I have the voicemail to prove otherwise. Then when I asked why he didn't let me know that LADWP has certain timing requirements EARLIER, which completely makes sense, he said that he was only just told this and he is a new employee. I told him that while I understand that this a free service offered through a utility company, the customer service and experience has been absolutely horrific. He said he understood and then told me good luck finding someone to meet my scheduling requirements. I said, "I recognize that I will need to take time away from work to accomplish this but I assure you, it will not be with JMS." For the record, I understand my request was difficult and a tall order, but all of this could have been avoided and everyone's time saved, had I been told the correct information in the first place and JMS trained their employees, new or seasoned, better. Had I known what the requirements were from the get-go, this all could have been pre-arranged with my office and without all the scrambling and unnecessary constant and frustrating phone calls. Long story short: DO NOT USE JMS! read more

Considering our experience, we are surprised at the low ratings we see on this site. However, the ones we read are for maintenance, which we have not used yet. I'll review that separately when we do. Our experience early this year was for installation of a Daikin system. We had an old Daikin (REALLY old), and since it worked so long and well for a part of our house that cannot be ducted, we wanted to update it before it finally gave out. Yossi is an authorized dealer. He came out, assessed our situation, reviewed the options, and we proceeded. We were on site to see all the work being done. The crew was knowledgeable and thorough. We are on a hillside, so it was not an easy task. While the cost was considerable, seeing the work done made us feel it was worth the price. The product has improved greatly since the model we had, (more efficient and quieter), and Yossi's suggestions of where to locate the units made us far more comfortable during winter weather than before. We just turned on the AC for the first time this week, and how marvelously cool we are. We're attaching a photo of one handler. If your situation warrants a ductless system, we highly recommend the Daikin and JMS for installation. We'll get back to you about maintenance. read more

JMS Air Conditioning and Heating - Daikin handler on AC mode. - Heating & Air Conditioning/HVAC Near Me - Van Nuys, California

Working with JMS has been easy and I appreciate that they're familiar with equipment in our building in downtown Los Angeles. I also appreciate that the tech was able to accept credit card and provide detailed receipt by email. Kudos to Tina, who is easy to reach by phone and responsive by email with regard to questions about scheduling and billing. Depending on your needs as an owner or tenant, they offer a variety of promotions and 'membership' pricing incentives. read more

I've had my units for 14 years and had many problems with other maintenance companies. JMS came for the first time and did a really thorough job. No one has ever told me why wooden shelving and books, etc. should not be placed right next to the furnace. The technician from JMS not just told me why, he opened the panel and showed me how close the pilot was. He also said I had to stop using my return space for storage because air flow was blocked, sending wrong information to the thermostat causing it to misread the temperature. I'm glad I found JMS. read more

The customer service is great provided by Tina Calhoun, CSR MANAGER!! When I first spoke to her to schedule my HVAC maintenance she was very nice and answered all my questions. The day before my appointment I found out the JMS is a part of the LADWP AC Optimization Program. I called the next morning and she said no problem I can work with you on that and we were able to reschedule my appointment and take advantage of the program. I appreciate the fact that she didn't try to make me pay for the scheduled service without taking advantage of the LADWP program. Thank you so much Tina!!! read more

I gave this firm a great review last year but times change. Their website says they have 24/7 emergency service but they do not. IRS Sunday afternoon, 100 degrees outside, my AC is not working at all, but they do not consider that an emergency. The dispatcher tried to give me some nonsense about how certain conditions have to be met for it to be considered an emergency. Than she admitted they didn't have anyone who could come out today. So, the website lies. I really liked this firm last year but would not recommend it now. read more

He was 4 hours late, and they charged ridiculous high on basic repair, DO NOT USE THEM.

I work at a company that has used JMS for years, mainly out of a combination of inertia and panic (turn to someone familiar when there's an emergency). We have a service contract with them, so they're supposed to service our four units, but they never do. And they're constantly in need of repair. Last week, one of our AC units began leaking so much fluid, it flooded the second floor of our building. We called JMS out, in conjunction with our handyman, who was there to actually repair any damage to the roof from where the water was able to leak inside. JMS charged us for running new pipes, repairing the existing, incorrectly-installed lines (which may have been installed by them in the first place, who knows) and getting rid of mold that had been growing inside the unit. He "repaired" everything. The next week, everything leaked again. I called JMS, told them it was an emergency. No one even bothered to get back to me to schedule an appointment. I called our long, long, long-term handyman to ask him about why the roof was still leaking. He went up, took a look, and told us that the "repairs" JMS made were done with duct tape. We are done with JMS. It's ridiculous to have a maintenance plan, and STILL have the AC units breaking down every year, and then to hear that the repairs are being made with tape? No. No no no. read more

The $59 tune up was a lie, at least in my case. The part I ordered was a factory part. Good luck with your business. read more

I responded to their $59 tune-up deal. They sent a newly minted sales pseudo tech guy who came and said he was going to service both units and make them work like new. Well, they wee installed new in 2007 and working perfect. Just wanted a tune-up. This guy took 2 units part and spent over 1 hour trying to get it together again. Never cleaned anything at all. LOL. What he did was to put a sales plan and pitch together on how I needed to change most of intake vent system. Proposed 3 "plans" ranging from $ 798 cheaper to $1,987 for "best one. " He left and main unit did NOT cool. A licensed tech was called in and he fixed problem caused by sales guy. I wouldn't fall for the bait and switch of Winter/Fall service. Total disappointment. read more

I went on a trip and got back to find water all over the floor. It turned out it was the ac unit. I didn't even know ac units can leak. I looked for some companies online and decided to call JMS. The guy came out and was very friendly and professional (even though my carpet was ruined he still wore shoe protectors) Turns out the drain line was clogged because no maintenance was done on the unit for a long time (oops). He cleaned the drained line looked over the whole unit and made some recommendations to get the unit running properly. Most of the work was included in the maintenance agreement which I signed up for (trust me it's cheaper than a new carpet). Through this whole nightmarish process dealing with Miriam and JMS was the least headache one. I will definitely use these guys again and recommend everyone else to do the same. read more

I was about to die from heat yesterday. My AC was broken and I couldn't even breathe. Even my dogs were hating it. I decided that now is a good time as ever to get it repaired. I did a quick search on the internet and found out about JMS. I called them and they came out to my house. They let me know exactly why my air condition unit wasn't working as good as the day I bought it. For one thing, it was resting on an incline (which is apparently very bad for ACs). They leveled it out. Also, it badly needed cleaning and the refrigerant gas recharged. After they did all that, I barely recognize my AC unit. It is working better than it has in many years. It is currently 72 degrees in my house and I couldn't be happier. read more

I see other five-star reviews on here, but my experience was very unimpressive: Tried to get an estimate to install a mini-split system. I should have sensed that this was going to be a waste of time when two different sales people called me to set up the same estimate -- apparently the second had no idea that the first had already called. They canceled the first appointment because the installer was running late on another job (although they were flexible about scheduling the second one). The estimator that came out didn't seem to know what she was doing -- I expected an experienced AC installer/estimator, who could talk about SEER, Btu, capacity needed, etc. Instead, what I got was a salesman who wanted to discuss financing and deals, but who apparently had never crawled about on a roof or in an attic, had no brochures or product information with her, and really couldn't discuss her product. Finally, she emailed me an estimate -- *$11000* to install a two-zone mini-split system in a 600 sq. ft cottage! If you've done any research on mini-split systems, you'll know that this is an *extremely* inflated price; even at retail (Home Depot) these units max out at about $2500. So apparently, this company wants to charge $8500 in labor to install a $2500 unit. ...or at least that's what I assume, since the "estimate" was just an email with a price. It had no information as to what kind of unit they'd be installing, the Btu capacity, the breakdown of hardware vs. labor, etc. Their website is slick and their salespeople call right away -- I'm guessing that this is a company that does a lot of volume, but with customers who don't know any better or don't try to call around to make sure they're not getting overcharged. read more

I am amending a prior review of this company. The owner of the company, Joe, contacted me, was very apologetic regarding miscommunication with his technician, and appears there was a reasonable misunderstanding. I appreciate that he made a personal effort to correct the problem and address my review. read more

After posting my review here, I was contacted by the owner to discuss my concerns about the scheduling and service (the air conditioner had been noisy since the service call). He acknowledged issues with the scheduler and told me that they had been terminated, and offered to send out another service person to make sure the work was properly done. He sent Michael Koskey, who had also serviced my furnace last winter. Michael is a very impressive technician. He is professional, intelligent, thorough in his work and in explaining the status and issues observed with the system. He worked on the air conditioner for a few hours, addressed all of my concerns and it is now running quieter than it ever has. I will continue to use JMS, but only if they can promise me that Michael will be my service technician. I truly appreciate the owners concern for the service I received and the fact that he made things right. read more

I called to scheduled service for an air conditioner, and they never showed up. I called again, and they claimed to have no record of my appointment. I figured I'd give them the benefit of the doubt, and I rescheduled for the following day. In the morning, I tried calling a few times and left messages asking to confirm the appointment (didn't want a repeat no-show). JMS never returned my calls. Finally, it was time for the tech to show up. He arrived during the last few minutes of my appointment slot, couldn't find parking, so he went home. I received a call from JMS asking to reschedule. I think not. At one time, JMS was the best. But that was many years ago. Now, the quality of their customer service has plummeted. read more

Do NOT use this company because they came out to look at my AC because it wasn't blowing air and the tech didn't seem like he knew what he was doing and said it needed replaced and wanted to send someone out to give me a quote but it's not very old and I wasn't comfortable with what he was saying so I called another AC company and they fixed it the same day. Unbelievable. I just can't understand how that can happen. read more

I highly recommend JMS i called and spoke to Tina she made my appt the service was great and she was super helpful! Everything was done professionally I have zero complaints If I could give them more stars I would. read more

Owner named Joe called me personally and provided care about his company and explanation. This company has 24 years of experience, the fact that he called means he cares about his customers, will use them again. read more

JMS installed a great ac and heating unit in my home. Fast service. Ohad was very attentive, made sure I was getting the right unit for my home. Claudia in the office was quick to call and set up my appointment and was very friendly. She answered my questions and concerns in detail. Overall great servies, the guys whom installed my unit were clean and quick. Thank you Ohad, Claudia and the EIT crew for their service. read more

Terrible experience. They called to change my appointment half day before appointment as i sit at home all day and do nothing. I have work, i took day off. I said that i can not do it then the guy on the phone started to ask me questions about my air conditioning system. Hello!!! I am at work, how i can give you all this information being at work and next day you have to work on it. So instead of apologizing for bad customer service he used it to cancel my appointment. Bad customer service, bad managment, bad attitude. read more

Wonderful to deal with! Dave came out and serviced my air conditioner and was really pleasant and wonderful to deal with. He was friendly, took his time and had my ac working perfectly! Highly recommended! read more

Eduardo came to my home to give my AC a tune up and install a free Nest thermostat - as part of the LADWP tuneup program . I couldn't be happier! More importantly, I've finally found my AC guy! Eduardo was Awesome! Honest, communicative and a hard worker. He also didn't mind answering my many questions. Which is something even my wife gets sick of. I'm so happy I chose Eduardo and JMS. read more

Now I will admit I never got to actually use the service. Called to schedule an appointment and the day before I get a call that my appointment would be re scheduled because they ran out of equipment. I can understand so their next scheduled meeting is a month from the original date. I'm committed and I wait. The morning of the scheduled date I call because I have no response nothing. They give me the same nonsense about running out of equipment and that they would be re scheduling for a month out. I took the day off to wait for them to get an I'm sorry we were suppose to call everyone to let them know. If that's not the worst customer service and relations ever I don't know what is. Again I haven't use their services and probably never will. read more

JMS upgraded our ancient AC system, adding a new unit for the second floor. Later we used them to replace the old first floor unit. Great service, workmanship, very responsive, kept us updated when running late or otherwise delayed. We definitely will continue to rely on JMS for heating and air conditioning needs. read more

Perfect service visit. Scheduled in advance, JMS gave a courtesy call the evening before and 30 minutes prior to arrival. Thomas the AC technician was professional and thorough, checked everything, cleaned all of the filters and let me know the things I could do to keep our AC operation efficiently. The quote over the phone was $125 and that's what they charged. It took about an hour. I was totally happy with the service visit. read more

We recently purchased and has installed 3 mini split Daikin units through JMS Heating and Air Conditioning. We are very happy with the se units and expect to save money by only heating/cooling the rooms we are using. I would like to especially thank Lee and Bill. Bill helped us figure out what we needed. Lee was one of the technicians on the project. He was exceptionally good at what he does, and was a perfectionist about the aesthetics of the installations. They were both extremely nice and very patient. Thank you Fran read more
