Mitch has done wonderful work for us over a number of years. I'm sorry I never rated him before. He shows up promptly, works efficiently, charges a fair price and leaves the work area spotless. read more

Probably the fourth or fifth time I've had Cool Max out. Same day service and repair. Great price, nice older gentleman who is respectful and always comes through. read more

It was triple digit temperatures in valley this week and my AC was acting up. Mostly warm air was coming out. My trusty technician that I've known for years was ex comminicado, so I pulled out my yelp app and found Cool Max Heating. Mitch showed up a few hours later after I called him. Troubleshooted the problem, fixed bad capacitor and electrical on condenser. Priced was very reasonable $390. Very professional and nice. Couldn't be any happier and highly recommend him for AC repairs. read more

Awareness Review I am very upset because of my experience today with Mitch. I contacted him to fix my HVAC air conditioner because it wasn't blowing cool air. Unfortunately, Mitch wasn't able to fix it. When I asked him what the problem was, he said he thought it was the power source. He mentioned he didn't have a long ladder to reach it and advised me to call another person to fix it, but still will charged me for his gas and service which i refuse to pay I asked Mitch to give me a report of the problem so I could inform the next technician, but he got mad, told me not to pay anymore, and said he would just return the screws he had removed. Fast forward, I called another HVAC company, and they were able to fix the problem. To my shock, the second technician asked if someone had tried fixing it before. He was surprised and concerned because the first person had mixed all the wirings. He connected the cold wire to the hot wire, which is very dangerous as it could blow hot air instead of cold. This could have been a serious hazard, especially since we have dogs at home. I hope Mitch stops doing this to other people. This was not only unprofessional but also potentially dangerous. read more

OMG :) Again I have to say Mitch is one of the few out there you can trust. Haven't needed him for about 4 to 5 years and today I noticed my ac was running longer to cool the house. So I texted Mitch and he advised me that was normal and especially with the hotter weather. Somebody else would have told me they needed to come out and assess the situation and act like they fixed something. Thanks again Mitch you are a credit to your profession. Sincerely S & S read more

My AC once again not working. The motor inside works but thermostat shows that it's not cooling down and still 90 degrees inside. Called Mitch and found out that the main unit outside doesn't work anymore since it looks like it's more than 20 years old. Even when he was able to get the fan working outside, the compressor didn't sound right as if you're starting a car's engine but keeps on dying on you. That's what it felt like. He told me it'd be better if I get a brand new central air unit and will give me better price than those other companies out there. He was very helpful and still came out at the last minute eventhough it was already past 9 in the evening! He was so nice that he only charged me $50 for coming out late at night. At least now I know what the problem is! I highly recommend Mitch! read more

What Happened? Our central air conditioning unit suddenly went AWOL sometimes yesterday. and we just realized that it has just been blowing hot air all day today. it was extremely hot today and the inside of our house was over 90 degree. We ask for quotations around on YELP for an emergency service and decided the to go with Mitch. Searching for HVAC services (on Yelp) in the Valley: Many of businesses gave diagnostic visits ranging from $35-$95. Mitch provided us a quote at mid range, but the sale point for us was that he was able to come in the next 30 minutes, so I found the pricing at the last minute call to be extremely reasonable. Services: Mitch arrived on time and diagnosed that our AC unit compressor capacity and fuses all have been blown out. Even though it was a bit hard to understand Mitch, he explained thoroughly and gave us a final price before he proceed with the repair. When we insisted that we can give him the check now, he told us to wait until he finished and complete the repair. Mitch spent around an hour on our roof at 3 pm! Do you know 3 pm is like the hottest time of the day? It was blazing hot! I thought his service was professional and extremely helpful. Mitch accepted checks! Overall impression: Mitch was our hero today! I honestly am very thankful that he could come over extremely fast and rescue us from the heat within hours! If you're in the San Fernando Valley area, do consider calling Mitch! read more

It won't be long before triple digit temps. hit The Valley so I tested out my A.C. unit the other day and there was no cold air. I did not have an HVAC company to call so I called a contractor friend of mine who referred me to Mitch at Cool Max. Mitch answered his phone and even though it was late in the day he said he'd be over within the hour and, he was. Mitch showed up, went right to work troubleshooting, diagnosed the problem and replaced a part that got us up and running again. I was very pleased with the quick and professional service and the cost was very reasonable. I would confidently recommend Cool Max to anyone who needs their services. read more

Situation: Our AC stopped blowing cool air during the hottest day in LA. Service: Mr. Ha was very responsive, my husband contacted him via yelp. He asked my husband to call him around 8am, he was luckily in our area and swung by at 10am. He quickly evaluated our AC and determined that our fuse blew out and was able to swap it out immediately. Safety: Mr. Ha arrived and knocked on our door, he was very safe and arrived with a mask and wore the mask throughout the service. Tip: Seems like he takes cash only? read more

Mitch was very honest and fair. I just purchased my first home and inherited a non working furnace. I called Mitch and not only was his diagnostic charge $30-$50 less than most companies he showed up that same day. It took him about an hour to identify the issue and instead of defaulting to you should replace your furnace he dissembled the motor and fixed the problem. Our furnace is working and cost me a fraction of what could've been. I Highly recommend and will be calling again. Hopefully not any time soon! read more

AC unit started to only blow hot air & the outdoor fan stopped. Tried a new filter inside & manual jump the fan but no luck. Contacted Mitch Ha thru Yelp & he showed up same day in a couple hrs! He checked all the electrical & the outdoor fan. Turned out the capacitor was the issue. Simple part he had on hand & was able to replace it in less than 1 hr. He also inspected around the AC unit & found another filter area inline on the return duct near the AC that was super bad! I didn't even know the previous owners had that there. So grateful he found that & explained all the trouble shooting. All said & done 450 got my ac running better than before & I got a quick hand on lesson for ac repair Thanks Mitch! read more

We needed our heater fixed. Mitch was here the next day. To say this man knows his stuff is an understatement. He is extremely knowledgeable and has the best work ethic. We found him from these great reviews. Hopefully we can help someone else! read more

Mitch came thru again! second time calling him again, this time it was for the leak on the copper pipe in our attic. called him around 9am the night before and sure enough Mitch was at the house 730am the next day. thorough troubleshooting, found the issue, explained what he was going to do to fix it and was able to resolve it within 3 hours. any ac issues, just call Mitch! you won't regret it. read more

Mitch was recommend by another family member. When we got out new house I called him to install a new complete system to replace the original unit that was draining so much power. He was able to recommend the best size unit for the house and not try to up sell you on things you don't need. Our system has been working strong since 2015. -quick response via text anytime of day. -clean installation with all required sealant -ability to come same day for issues (I had an issue where my AC didn't turn on. He was able to find out that the solar guys didn't connect my breaker on and fixed it within 10 min) -doesn't up sell. Tells you what you need with different options for units read more

We've been having issues with our heater since last winter. We've had a few people come out to look at it, all with varying reports back, but nothing definitive about what the issue was. When Mitch came out the first time, he was able to see one of the problems, so he replaced that part. The issue was that there was also something else wrong with the unit that could only be diagnosed once the part that was broken was fixed. Mitch is very knowledgeable, very kind, and even took the time to draw me a diagram to explain the situation. When the heater stopped working after the initial fix (essentially it overheats and then shuts off to cool down before starting again), I texted him at 8:30 at night, he responded, and then even texted back at 7 am the next morning to see if it was working, because he knew it was chilly and didn't want the kids to be cold. He came out that morning, did another fix, and now the heater is working again, and has been so far. Because the original part he fixed was pricey, he barely charged me for any of the work he did the next day, which could have cost hundreds more. His ultimate recommendation was that we'll need to replace the unit, because in his honesty, he shared that he could keep coming back and replacing the failing parts, but we'd just be throwing money away. He doesn't even do heater installs anymore, so his recommendation was not based on getting the money for the install service. Mitch will be our go-to for our HVAC repair needs for the future. read more

Called him for AC repair. He Came instantly. My AC was not repairable. He was honest and reasonable. At least I knew this right away. I need a replace my AC! read more

Here he is, just like some other reviews this guy starts babbling to himself in his native language for some unknown reason. Merely thought he could just arrive at my residence and top up my freon, with "very hard to obtain gas" so "I'm going to extort as much money as I can from you" as this freon is hard to come by. Nonsense and a complete lie, it's the most widely used freon in the industry. I actually has a freon leak which he didn't bother to detect - that's why I needed the freon topping up, but hey, repair the leak first, then top up, or else the freon will just leak away again, plus the fact that it harms the ozone. You thought you were clever, taking your money and running, but here it is, a truthful review. Steer clear of this guy at all costs! read more

I'm I'm giving 3 stars because he got the job done, but he over charged me for a capacitor that's is maybe $20. He came at first, no introduction ( which I thought was weird), and asked where the unit was. After he assessed it he came down and an said that I needed some type of battery and that it would run me $390. Me not know king I said okay. Then I asked after I paid what he replaced, seemed hesitant to show me but he did. I then researched it and the part is about $20. It took hime about 40 minutes over all, I then called other companies and asked what they'd charge for something like. I was told about $200's. So I feel I kinda got screwed but lesson learned. read more

Mitch did a great job for us. He arrived to fix our air conditioner 30 minutes after we reached out. He went out of his way to help us on a hot day. and was very reasonable with the cost. Thank you Mitch read more

My AC stopped blowing cool air some time before midnight last night. I called several AC services in the SFV in the morning but most of them gave me a time frame between 4pm to 7pm. I needed it done at a specific time due to my hectic schedule. I finally called Mitch and advised him of the issues that I was having with my central AC. I asked Mitch if he could come by my residence around 1pm. Mitch agreed and showed up just before the scheduled time. Just as I suspected, the issue that was causing the problem was the capacitor. The last time I had it replaced was 8 years ago. Mitch did some initial diagnostics and replaced the capacitor in approximately 40 minutes. Mitch was very professional and got the job done promptly. My AC was up and running immediately after Mitch completed the task. In my opinion, the price I paid for the job was on point. read more

Cool Max Air was recommended by my co-worker. I'm very happy I contacted them. They are very knowledgeable, professional and gave me the best price for my new unit. I couldn't be happier with them read more

I wish I could give this review more than 5 Stars. Mitch Ha at Cool Max Heating & Air Conditioning was beyond amazing. My air conditioning unit stopped cooling late one night during a heat wave. The next day was supposed to be 110 degrees, and I was worried how I'd survive. I had been a long time renter and so this was my first experience finding an A/C repair person. I found this place on yelp and saw that it was "open 24 hours." It was 3am, but I thought "Oh, they must have a call center." So I called. After it rang a couple times I thought, I better hang up in case this is someone's personal number. After I hung up, a second later I get a call back. It was Mitch very kindly saying in a tired voice "Cool Max Heating & Air Conditioning." I woke him up and I felt terrible, but he couldn't have been nicer. He told me to text him my address and he'd be there at 7am. Wow!! When Mitch arrived, he quickly deduced the problem, pulled apart my A/C unit and replaced the broken part. He had fixed it within a half hour!! All before the temperature climbed to that dreaded 110 degrees. He even gave me a little lesson about how to tell if this same part stops functioning! Mitch is a life saver! I have found my A/C and Heating repair person for life! I HIGHLY recommend you give him a call (but maybe not at 3am....even though he will answer ;o) Thank you again Mitch!! read more

Strange.. wanted to charge $290 to change a $8 part that took my relative 10 min to change. This was back in December 2021 for my wall heater. He barely said a word and just made a grunt and walked away when I said I would think about it. Not professional at all. read more

I have seen good reviews with Mr. Myung Ha at Yelp. Called him up and setup an appointment last week on Wednesday. This person acts so fast and schedule the work right away. My AC unit is not blowing enough cold air and we're sweating here in Santa Clarita. He just found out that both the condenser outdoor and the fan coil unit at the attic area has ice on it and also require to fix the freon and some leaks along those lines. It's an excellent service. No question about that. That night, we're freezing and my kids felt it's winter at home on summer night. It took me a week before I post my review as I need to find out if this will continue eventually and it did. What more I can say? He seems to know his job well. Will recommend him to friends and family. :) Btw, his fee is reasonable for the amount of work he did. read more

He ok if u dont mind getting ripped off. He shows up, and just gets it done that is why im giving 2 stars.. the problem was the price he gave me on refilling my freon on the phone. He quoted me one price per lb of freon so i said ok. I gave him my address, he came, started working then told me a price close to double just to refill the freon..!!! Smh!! My mini split has a slow leak and i told him i just want to add freon dont worry about diagnosing anything. Once he hooks up to my lineset he begins to mention the hightened price..so i told him NO! Then he goes, "oh im already here and hooked up, if u dont do it , i have to charge you the my service fee for showing up and hooking up", which was a little more than half of charging my system ! Total bs! So i just sucked it up and had him charge it. I didnt want any type of reprocussions. BeWare... read more

My AC drain was clogged and I had a leak in the garage. I called Mitch during Labor Day weekend in the 110 degree heatwave and he came to my home within an hour. He was very respectful and diagnosed the problem right away. He even walked me through what he was doing and shared his knowledge with me. He fixed the problem and gave me a discount because the problem was easier to fix than expected. I will be contacting Mitch for all AC related issues. Thank you! read more

I'm truly grateful for Mitch- he's been a lifesaver for my HVAC system, not once, but twice. First, on a freezing winter day, my furnace gave out. I was really hoping for a fix when I stumbled upon Mitch on Yelp. 1.5 hours later, he was at my door. He quickly pinpointed the issue, a small component gone away. After getting the replacement part from a local store, he had my furnace running again. Then this afternoon with the temperature of 102 degree, my AC stopped working. I reached out Mitch without a hesitation. Since It's already 3pm, I wouldn't expect Mitch can come here on the same day, but I was told he would swing by in 2 hours. Again, he showed up at my door at 6pm, imaging the peak traffic situation during those hours. With his expert touch, he swiftly resolved the problem in just 10 mins by replacing a power source component. Unlike another technician who suggested an $8,000 overhaul of the entire system last summer for the same problem, Mitch is honest, never pushing for extra sales. Most issues are a cakewalk for him. I'm just really glad that I discovered Mitch who ensures I stay warm in winter and cool in summer. read more

My AC could not handle 104 heat summer and was blowing out warm air. I called Cool Max and Mitch answered right away, within an hour he was here.

I would highly recommend him for anyone with HVAC issues read more

AC stopped blowing cold air at midnight. I called 5 different local AC service places at 8am on a Sunday morning as I needed my AC unit to be fixed ASAP. Mitch was the only one to pick up and told me I'll be there in 30 mins. 30 mins later Mitch was knocking at the door! Mitch looked at our AC condenser, did some diagnosing and pointed out the problem. I asked how long will it take to get the parts? He said I already have the parts. Literally 2-3 hrs later, my wife tells me the AC is blowing cold air again! Happy wife, happy life right? lol Thanks Mitch you're a life saver! Seriously. If you're looking for a technician that you can trust, you can definitely count on Mitch! Friendly, Experienced, Honest, Prices are reasonable, not over priced imo. I would definitely give him a call back for any future problems and definitely would recommend him to friends & family. Thanks Again Mitch! read more

Was very responsive and available to come out right away, which was great. Identified the problem (at least seems like it) as the control module, so far so good. Said this was an expensive part and that overall project was ~$650. A bit steep but I don't know much about ACs. I asked about how labor/parts break down and he said labor $300, parts ~$350 but he wasn't sure. $300 is a bit steep but I want this over with so I offered to pay $300 (WHAT HE ASKED) + whatever the part costs. Well, that didn't work for him. At all. That's not how he does business, and he's never done this, and if I don't like it, I can just pay service fee and he would leave, and... Anyway, he left with service fee. The part appears to cost between $150 and $200. Oh, and as he was leaving he offered $350 for labor + parts, I guess somehow labor rate went up by the time he climbed down from the attic. Either that or he knew full well he was trying to rip me off. Look at the rating and guess what I believe. The only question really is whether he was trying to rip me off by $150 or more (if he can find refurbished unit or clean this one). Beware... read more

Mitch just left our house. One word to describe his service: quick. Our AC started blowing hot air. I have an infant so needed someone to service asap! I called him, was here in about 40 minutes. Diagnosed the problem, changed the part that wasn't working, and was done in about 30 minutes...geez that was quick! Best service ever. Even struck up a conversation we waited for my husband to return w/cash...very nice man. He said he's available anytime for emergencies too. Will definitely save his number for future rederence. read more
