They do quality work and clean up after themselves. Very professional and friendly. They will get back to you when you have questions, and will work with you. I highly recommend JM Heating & Air Conditioning. read more

BEWARE. I came here just to warn people that Jimmy doesn't seem to support his ACs after he's done. But then I started reading some of his other reviews, and can confirm it's a pattern. It looks like he just takes the big jobs, and then years down the road, when something goes wrong... He completely flakes. My renters took time off work to let him in the house... and he was a no-show 3 times in a row! No communication. I eventually went with someone else. If you want someone to stand by their work, I cannot recommend Jimmy. read more

I am a freelancer - a sound mixer for film. I am used to working with clients who must trust me to be fair and honest as they may not entirely understand what I do and what it costs. Because of this, I have developed a keen sense of sizing up a person when I am in that situation. This is my second time trusting Jimmy to maintain my HVAC. There is a solid sense of character that is in Mr Mendoza. He is a great listener. He enjoys meeting people and he takes an interest in us clients beyond the HVAC repair. These are signs of integrity and confidence, He did a terrific job at a fair price and I would hire him again. read more

We had two other companies come out saying we needed a whole new unit due to our compressor not working. Quoted me $8000 +! Jim did his diagnoses, checked our capacitors ( the other companies did too ) and determined that one was not working. He fixed it for $250! What a life saver! I highly recommend JM Heating and Air. Super realiable, professional, friendly and does top notch work. read more

They hands down the best HVAC company in Los Angeles! From start to finish, their service was top-notch and exceeded all of my expectations. I called them in a panic when my air conditioning unit stopped working on the hottest day of the year. They were able to schedule a same-day appointment and arrived promptly at the scheduled time. The technician was professional, knowledgeable, and quickly diagnosed the issue. He explained everything to me in a way that was easy to understand and provided a fair and competitive quote for the repairs. The repairs were completed quickly and efficiently, and my air conditioning was back up and running in no time. The team truly saved the day and I couldn't be more grateful for their excellent service. Thank you for your exceptional service! read more

So two of my good friends recommended him to us when our AC refused to cool in the 112 weather. We knew we were on borrowed time for our unit so I got three estimates and chose Jimmy. He was the lowest price, he was very friendly and accommodating even in this heatwave. He squeezed me in for an appointment after another one and was 30 minutes late because of traffic but communicated why. We received a hand written estimate. Luckily he had a day within the next week to get our job done. He arrived on the day of install with his crew and was able to replace our unit in one long day. The guys were friendly and nice. They did leave some trash but it was such a long day, we were grateful to get it in before the next heatwave. We did not pay him until after the install and check up a few days later. I would recommend them but know with COVID some AC and heating units are on backorder, so not every unit may be available. That is not a fault of the installer. read more

Have been using Jim for 7 years now with ZERO issues. I have recommended him to countless friends who are very happy with his work. I am SHOCKED by the negative reviews of his company. Seems to me that it is a "them" problem and not really an issue with Jimmy. Jimmy is a jem and I would never use anyone else. His work is exceptional and beyond reasonably priced. read more

Jim and his crew are the best! Honest and reasonable! And super friendly! I needed my furnace and thermostat replaced and it arrived quickly. They made sure that everything that needed to be moved was back in its place and cleaned everything up. Highly recommend! read more

Extremely rude and unhelpful. Installed a brand new year one year ago and now there are problems. I believe he doesn't know how to fix the problems. Had to hire several companies to see why heating unit is not operating properly with a new unit. He is unreliable, rude, obnoxious and simply doesn't know his job. I would NOT recommend this company and NEVER do business with them. I am filing a formal complaint against his license and will have spoken to several attorney in order to sue him personally for selling and installing an defective unit. DO NOT TRUST. read more

Rude and disrespectful. Doesn't listen to any concerns I've had and disregarded everything I said. I did not want any flame test while my 10 month was sleeping in the next room. He used a broken vacuum and flew dust EVERYWHERE in my apartment. read more

JM Heating & Air Conditioning - Heating & Air Conditioning/HVAC Near Me - Burbank, California

Unfortunately, I took the advice of a friend and hired Jim Mendoza without doing any research. If I had, I would not have hired him. I may have saved myself a lot of headache, and money. I had to hire another company to fix the problems his company caused when they tried to install a new unit in my house. After multiple times of scheduling appointments that were not met - nobody would show up at my house - and nobody would answer the phone or respond to a text message. I started getting extremely frustrated. Finally, on the day before Christmas, with no heat in my house, I left a message threatening legal action. I got a call back on Christmas Day from Jim, claiming he was in Mexico, in the emergency room, with no excuse why no one had showed up at my house. After hiring another company and spending $7,000 additional to fix what his crew had messed up, Jim claimed during a phone conversation and in an email that he would "make it right," and that he would "get me paid back," intending to repay some of the money I had paid to him. That was three months ago, and I have yet to hear anything about what he intends to do to make it up to me. I am not going to go into all the detail about how many things were not done correctly, and I honestly feel badly for the crew, because they are really nice guys, who just have an irresponsible boss/owner, but I cannot stress enough how much I recommend NOT hiring this company. You will regret it. I spent $16,000 to install a new HVAC unit on my roof, and it never worked properly, until I hired another company to come and fix all the errors caused by JM Heating & Air Conditioning. If I had more time and patience, I would take him to small claims court, but I just don't. I should also mention that my friend who recommended him in the first place has since stopped working with him as well. read more

Used JM air few times in past was happy BUT my tenants air went out .. called Jim him came out he was already saying the air unit probably need refrigerant because the unit on the other apartment had needed some in the past .. WTH? He went on roof quickly said he'd be back later to add refrigerant never could tell me why he thought it needed refrigerant.. he added it, charged me & that night no cold air .. had to call him several times said he'd be back in the morning- in the am I got a text that said "find somebody else to fix it -no charge". New AC tech came said system was leaking refrigerant couldn't understand why Jim didn't even notice that because the two copper pipes were rubbing together and making so much noise that could be heard from below . .. basic AC diagnosis.. IMO shoddy, money grabbing work Left a mom & little girl w/ no air in heat wave STAY FAR AWAY from JM Air (Jim Mendoza) read more

Wonderful! Quick! Responsive! Reliable! Jim gives you many options for your needs. Use this company for all of your hvac needs. read more

No matter how nice and efficient that sales person is (ours was) it isn't worth dealing with shoddy work, or just bum luck that leads to a non-functional HVAC system and months of aggravation and broken promises for calls back, visits, working parts preferred or poor diagnosis of the problem. We have had a broken a/c head on one of our thermopompe heads for three months (all summer), they have made three appointments with us, and they still don't know what is wrong. Rather than calling us back, they are now just avoiding us. Pay a bit more for your heat pump and choose a company with good service reviews... NOT JM air! read more

Called a few places to get quotes, and I ended up going with Jim Mendoza; I am only writing this review only cause I am shocked at some of the other reviewers, I didnt have any issue with his service and he ended up finding more issues during the install that he fixed out of his own pocket. I have recommended him to several friends who all only call him now. Maybe the other reviewers are confusing Jim with another company? read more

Used him twice at two different residences. Initially gives you a good price but once you start having problems the guy never answers the phone. Would never use his services again. For those of you who are happy now , wait until you need him and his crew to service or respond to warranty issues. I regret giving him our business. He came highly recomendéis from family members. read more

If you can get them to pick the phone up, return your calls, and actually get to your location to do the job - they're great. Unfortunately, getting them to do any of the above can take months or an eternity. Don't expect a phone call back, don't expect them to call and say they'll be late, and definitely don't expect them to call once they missed the appointment completely. We had another company come out in one day, diagnose the issue, and do the job within 3 days. After dealing with Jim, it seemed like a miracle had occurred. read more

Jim came out at the end of his day to fix my ac in a heat wave. The relay was bad. He fixed it for half the price I paid for the same part twice before from another company. He explained that the relay they kept putting on was the cheapest one you can buy. That was long time ago when he was just starting out...... And I have not had any problems since. Thank you Jim. I will never forget that. I will be contacting you soon I'm sure the unit needs replacing. read more

Been using JM heating and Air for years. Been very happy with their work. Wonderful service and very fair pricing. Also very creative and patient when it came to a difficult project. Sometimes hard to get through but texting or calling Jimmy on his cell works! He has always come through! read more

Won't pick up the phone. Don't show up when they say they will. Bad work that broke days later and won't come back to fix. Save your money and go somewhere else! read more

So happy I used Jimmy and his guys. They gave me the absolute best deal after I had been screwed around witb for about 2 months with a company I was using through AHS. Jimmy made it easy. His guys were beyond professional, left the place as clean as they found it, and overall did a great job. Couldn't be happier and would use them again and again. read more

Jimmy did some work for me and I have some questions regarding the fan on the AC but impossible to get ahold of him. Voice messages won't even go to voice mail because the mailbox is full and instantly disconnects. I texted him and still no reply. No way to treat a customer. I will have to drive over there I guess. read more

We called, they answered and the problem was fixed in a few days. Jimmy and his crew were a pleasure to deal with. Jimmy went beyond the call when visiting our home in the evening to remedy a gas problem. He returned the following day removed our heater box and returned two days later with a rebuilt box. His team installed and replaced parts to our gravity heater and for the first time in years we have a warm kitchen and dining room. Thank you! We WILL recommend JM Heating and AC to our friends. Difficult to believe the negative reviews based on our great experience. read more

Jim has done a lot of work for me over the years, and has never disappointed. The most recent job was a two unit system in an older home, which had a lot of challenges. Jim came up with some very creative solutions and, as always, completed the job for a very fair price. He and his crew are very detail oriented, down to painting the registers to match the walls, and spending the time to make sure the job is done right, including adding a light in the attic and making some minor repairs to things that had nothing to do with the HVAC install. I will continue to use and recommend to others. read more

Julio Guerrero at 5622390829 charged me $300 to fix an AC, the next day it did not work and he stopped returning my phone calls.

Jim Mendoza came to my home on Jan. 7, 2015 to give me an estimate on a new heating unit. It is over a month now and I followed up with several phone calls to his office for the estimate. I did not receive a return phone call or an estimate for the heating unit. If he does not want to do the work it would be nice if he saved me the time coming to my home. He was referred by my neighbor and if that is the problem he should be upfront and say so. I do not appreciate people who waste my time. read more

If I could give them zero stars or negative stars, I would. First of all, they no show, no called on their first appointment to look at our heaters. The second time, they were re-scheduled in the morning; Jim called and asked if he could come in the afternoon. Even though we were annoyed, we agreed. So what does he do? He called that afternoon (30 minutes after his rescheduled appointment time) to say he ran out of supplies during the day and since everything was closed on the weekend, he asked to reschedule. First of all, he had not looked at our heater yet, so how could he possibly know what supplies he needed?! Second of all, WTF?! You are messing with peoples schedules with your BS. We rescheduled again and Jim did not show up but sent two of his guys. They ended up replacing two heaters and installing thermostats. They did not ask me about the placement of the thermostats in the house and by the time I looked up, they had two thermostats mounted with brown wire running on the outside of the wall and they had drilled two holes into the hard wood floors. Again WTF?! The guy seeing my face tells me that our landlord told them to do it that way. So I call my landlord and he did not instruct such wiring and is even sending his contractor out to fix the ugly wiring. There is no way to fill the holes in the hard wood and I doubt we'll be replacing panels of hard wood. Fast forward, we get a gas bill 3 times more then our normal gas bill. We call the gas company and both heaters were leaking gas. The gas company guy even said that we were really lucky because if the gas had caught, we would have had a house fire because of one of the areas the gas was leaking. There were multiple areas with both heaters where the gas was leaking. Both heaters were red tagged. Since they have already been paid, my landlord demanded they fix their crappy work. We made an appointment for between 9am and 930am. 1030am rolls around and I finally call Jim. He said he did not write down the appointment when we spoke so he forgot. He said he would be on site in the next hour. We really just want this to be fixed so we can get them out of our hair and never have to deal with them again. Horrible service and horrible workmanship. We would never recommend them. read more

Jim is a great guy - He's busy, yes, but does great work and his crew is so easy to work with. I've used him on several projects, new systems and replacement systems. All are still in place and purring like little kittens. read more

Would give zero stars if I could. My building uses them to fix our ac/heating and I requested an appointment change to a time when I would be home and apparently this is the worst crime ever committed. He responded with "are you going to pay extra? No then my schedule does not revolve around you princess". Excuse me?! My building pays for repairs. I shouldn't be asked to pay extra just because a lazy employee doesn't want to work past 5pm or on the weekends. Absolutely vile and unacceptable behavior. I started to ask him again when we could reschedule but oops too late he hung up. Basically was having a tantrum like a little child. Is this supposed to be customer service? After being treated so poorly, I texted him and told him EXACTLY what I thought of him and he responded that I I didn't deserve help because I rented the unit instead of purchase. Disgusting behavior. Just because he woke up on the wrong side of the bed is no excuse to treat someone so poorly. Be a professional, stick to business, and reschedule the appointment time. Not complicated read more
