Nino was very professional, he explained the issue in detail, took his time, and replaced my thermostat on the spot. Price was reasonable. I highly recommend them. read more

Nino got our AC working in no time. He replaced the capacitor and our AC has been working fine since. He had a few other suggestions as to how to keep our HVAC in top shape. As we all know we pay for knowledge and experience. Price was under $450 for capacitor and labor. 06/2026 read more

The quality, service and care are unmatchable. Joseph, Manny and Anastasia are committed to taking care of their customers. I would highly recommend them to my family, friends and neighbors. I actually have. read more

Love these guys! We've had California A/C out twice now for annual maintenance for our HVAC system. The communication leading up to your appointment is second to none and the professionals who show up are as kind, knowledgeable, and respectful as they come. Everything from the little stuff (booties on inside the house without being asked) to cleaning up after they're finished make these guys my continued choice for our HVAC. Appreciate you guys! read more

California A/C Heating - Heating & Air Conditioning/HVAC Near Me - Los Angeles, California

I need to replace my old HVAC and decided to call this company after seeing all the great reviews on here. Manny was very professional, knowledgeable and paid attention to details. Due to the inadequate ductwork in my house, he recommended to replace with the ductless mini split system. The quote he provided for the top rated system was much more reasonable than the other quotes I got. Unfortunately due to some logistical limitations, I have to choose the existing duct ac system. Nonetheless I would highly recommend Manny and this company for any HVAC repairs or installation. read more

We had recently moved into our new house and needed to have our Heater examined by a professional before using it. That's exactly what we got and now we have the peace of mind to use it. Aaron came by and provided a quick maintenance service ($95 which also went to any major repair if needed), a carbon monoxide detection, (which showed no carbon monoxide) and recommended a different filter size than the one we were using. Once he finished, he took down the necessary information of our unit for records. Overall, his service was prompt, simple, and very helpful. I look forward to employing their services again for our A/C Unit for next year. Nice and easy! read more

Had them come service my AC, did a great job. Answers a bunch of questions and told me what was and wasn't needed maintenance wise. Will definitely hire again. read more

Konstantine did a great job on short notice for me! So happy to have found this business on yelp and having reached out to them in yelp and by phone to get them seen in 3-4hrs. My capacitors were replaced and my old AC unit was working, but overnight the motor died and he was back the next morning at 7:30am! They even answered a 4:45am text while it was cool out (the day would have been baking hot heat wave otherwise). He credited the first visits repair cost to the motor replacement and all has been great since, especially since the next two days were hotter than 95*!! I'll use them again for sure! Thanks Konstantine!! read more

Amazing experience. Called due to a broken AC and same day, I was scheduled for a consult and the problem was repaired. Our technician was extremely kind, knowledgeable and honest. Appreciative for the all the help! read more

Rainwater got into our old gas heating furnace, shorted out the control board and damaged the gas valve. As a landlord, I needed the heating repaired ASAP for the tenants. Konstantin did the troubleshooting within hours and made the repairs very fast. Other repair quotes I got from elsewhere had a 2 day lead time just to get the replacement parts. Also, I appreciate Konstantin always texting me his estimated arrival time and always arriving on time - much appreciated! read more

My central air unit would go out on one of the hottest days this week. To give some time perspective on how fast this company is, I contacted California A/C & Heating on 10/6 around 4:45pm. I spoke with a lovely young lady who managed to schedule me for an appointment the following morning, Saturday, between the hours of 9/12. 8:45 Saturday morning I get a call from Konstantin, one of their service technicians. If you have read the yelp reviews, then you know he is in many of them, all positive and rightfully so. He arrived at my home around 9 am, very nice gentleman. He asked what the problem was, I showed him the access points to the roof unit and 45 minutes later, my home was back to it's chilly self. Overall excellent experience, from first call to completion of service. Worth every star. Thank you Konstantin and California A/C & Heating. I will be seeing you guys next April for service. read more

Ara came out to see why our AC was not working. He was able to identify the problem and fixed it on the spot. Ara and the entire company have been nothing but extremely professional, and very helpful. And more importantly, they were extremely honest with everything. Any problems I have in the future I will be going through them and only them. read more

Honest and Reliable After contacting a couple of ac maintenance companies, I felt comfortable scheduling service with this company they were very detailed on services and cost. Will definitely hire again. read more

Our upstairs AC wasn't working so I called Kevin and he promptly came out to check out the situation. It was grim and the whole system needed to be replaced. After getting a quote we went ahead with the repair. His team was out the next day with all the equipment. The crew blanketed everything from the front door up to the attic and were very courteous and considerate as I was working from home that day right next to the attic access point. They replaced the attic air handler as well as the outside evaporator. They also flushed out the drain lines while they were up there. Kevin is great and easy to work with and I'd call him again with any issues. read more

Constantine, who I've worked with seems to be very trustworthy. He always shows up on time, and is available for conversation about concerns and with done...before and after. I have used him 2 or 3 times and will again. read more

Anastasia the receptionist was so helpful and honest with our ac situation. Even though they couldn't fix our unit, she and the technician took their time and explained the best way to go about it. Anastasia was patient and I wish this company the best. Thank you guys so much. read more

VERY happy with this company! They came out same-day to see why my AC wasn't running. It turned out to just be an out-of-place sensor so they only charged me $95 for the service call. They could have easily told me the sensor was broken and charged me more so I really appreciate their honesty. I'll be using them for all my future HVAC needs. Thank you again Aaron! read more

Called them on a Saturday and two hours later the technician showed up and fixed my AC. Great work and customer service.

Had an A+++ experience with California AC and Heating. Konstantin was amazing. Very professional and very punctual. Worked amazingly with my tenant at my rental property. Made it so I didn't have to worry about getting out of work. He was able to diagnose and fix an issue with an old ac that I have been dealing with for, literally, the last ten years. I have had numerous HVAC guys come out in the past, and they all "fixed" the problem. This included finding a new bandaid to keep me happy. Konstantin came one day to diagnose and another day to take care of the issue. My ac is a squashed unit in the ceiling of a first floor older condo building. My condenser is on the roof of the third floor. That was alot of my issue. He did what no other ac guys could or at least wanted to do. Highly recommend and would give six stars if that was an option. Thanks again, Konstantin! read more

So refreshing. I had no heat. Aaron came and checked the unit found no issue. Went to the thermostat which was newly installed by another professional company and found the problem in a minute. He made sure it was working and it was a very reasonable. So nice to find a good local company. read more

California AC came to the rescue when the fan motor broke on our 20+ year AC. Called them and they were out within two hours to quickly identify the issue, provide an estimate and then got the job done. Bookmarking them for future AC/Heating needs. Konstantin was very helpful and professional. read more

A week ago, for the first time, our thermostat died completely (went blank) after our HVAC heater struggled to start during an automatic setting, then it turned back on a few minutes later. Didn't think much about it... After that we still continued to use our heater only in the morning when we get ready for work but we turn it off as soon as the desired temp is reached, and we had no issues with it. Then a week later, it happened again. I turned on our HVAC heater. It worked, and it reached my desired temp with no problems (left it on the automatic setting). Then a few minutes later when the temp went below my setting, I heard that the furnace in the attic was loud and struggled to start up again, then our thermostat went blank again (completely died). Then a few minutes later the thermostat came back to life but this time the HVAC heater didn't start, instead, it followed by the burnt electrical smell! At this time I knew I needed to call a professional to take a look at the problem. I was scared! I searched on Yelp and glad I have found this company. Konstantine answered my phone call right away, and in less than an hour on that same day he was at our door! He checked our furnace, and found that our capacitor wasn't working properly. I think we just found our family A/C & Heating guy! We'll definitely reach out to Konstantine again for our A/C and Heating needs! read more

Turned out AC on for the first time of the season and our roof unit had a short circuit. Called Konstantin @ 7am on a Saturday and he was at my door by 8:30am. Very professional and courteous, Konstantin fixed the problem quickly and efficiently. In addition to his ability to troubleshoot and find the short quickly, Konstantin took care and time to clean the attic access door with windex and paper towel, leaving the access door looking better than when he arrived. Will definitely use Konstantin and California AC again. read more

My Mother had issues with her Air Conditioning and so we contacted Konstantin to have a look. This is her review: I could not be more pleased with the knowledge and expertise of this repairman. He found a filter which I didn't even know existed, in one of two A/C units in my home... which had not been changed in a decade! No other repairman realized that it existed...! The price was more than fair. Astounding! Usually, I feel taken advantage of because I'm a woman. Thank You Konstantin! read more

Our nest thermostat stopped working over the weekend, I popped into the attic space to try to figure it out on my own but I realized I needed to call in the pros. I got in touch with Konstantin Sunday afternoon and he was able to come over first thing in the morning. He found the problem quickly and was able to source a replacement part within a couple hours which he then installed quickly and got our heat back up and running. Konstantin was really helpful and nice and I would highly recommend giving him a call if you ever have any hvac issues and want an easygoing no-hassle experience. Great company! read more

Very professional. Aaron made sure he called when he was on his way and provided an accurate time frame of when he could arrive for the appointment. He answered all of our questions and provided plenty of helpful information regarding our issues with our AC unit. He took the time to explain how we could avoid the issue in the future. read more

First, I want to thank the YELP reviewers who posted about this company. Your reviews are how I found them. And what a find! My 3-year-old HVAC unit had an issue that prevented the heat from coming on as scheduled. Even when the heat was manually adjusted higher, the unit would not kick in. I called the company, and Anastasia was great - working me into the schedule the very next day. Then Konstantin came out - and even texted ahead to let me know his ETA. It looked like a quick fix, but the problem persisted. So I called back, and he returned the following day and found an additional issue - a faulty gas valve. He installed the replacement part, and now the heater is working perfectly! This is an excellent company that I would happily recommend to anyone. Konstantin is professional, knowledgeable, punctual and nice. Thank you Konstantin and California A/C & Heating. See you in April! read more

Cali A/C did a great job! Their pricing was fair, they worked quickly, and it was so easy to communicate with them. I'm really happy with their service! read more

My AC was acting up, wasn't consistently shutting off, also needed yearly maintenance. Konstantin fit me in quickly, was straight forward, efficient, and friendly. read more

I can't recommend Konstantine enough- he is extremely reliable, easy to work with, does good work for a fair price. We hired Konstantine to redo our duct work but after seeing how efficient he was we changed our minds and just asked him to put in a brand new system. He went out that night bought our new system and came the next day at 7am with a crew. He had a full schedule with other clients the entire week but found time to handle our project. I highly recommend him. read more

Excellent service. The tech arrived on time and phoned in advance to let me know he was on his way. He did a thorough inspection of my home a/c and furnace. I found the tech to be honest, knowledgeable, and totally clear in his communication. He even did a bit of minor handiwork to re-secure some wire mesh for rodent prevention on a cover connected to the a/c unit--this work was above and beyond! I tried to give the tech a tip for this extra work and he refused. I will definitely be hiring them again for any future needs. Highly recommended. Clearly an excellent family-run business. read more

Konstantin is the best!!! I have used California A/C & Heating services multiple times now. Once for A/C check up and maintenance and also to change an old AC thermostat to a new updated one. Konstantin made the same day appointment available and was punctual. He stayed and made sure the system is running well. The time he spent with his expertise, hard work and patience to fix the unseen problem in the A/C unit on the roof is commendable, and the pricing is fair. When I had questions again and called him, he was very responsive and reachable. He is very knowledgeable and professional. Highly recommend!!! read more

I highly recommend Konstantin and his team. After looking at multiple vendors I picked California AC and Heating to replace my aging AC and Furnace with a new system. Konstantin was very helpful and open in explaining what he would be doing and what the cost breakdown would be - this created trust - his price was also very reasonable for the level of service he provides. He showed up on time on the day we agreed and performed the replacement according to plan and with a lot of professionalism. The lines of communication were open the whole time. I would definitely use his services again in a heartbeat. Gabe Monrovia CA read more

Konstantin quickly ascertained that my furnace needed a new igniter. He first tried what was in his truck, but it wasn't a good fit, so promised to return the next day with the right part. The next morning, my furnace is back in action. Super fast and efficient! I will call him again. read more

Efrain showed up and made a lightning quick a/c installation at my apartment. They hauled off the old unit, which was 25 years old at least, and left an energy-efficient unit in its place in less time than it takes to order a milkshake from a drive through. They basically saved my summer. #calicool read more

I called at 8:40 this morning because my heat was not responsive, at 10:41, I am writing this review with a toasty house, as Arron arrived timely, assessed the situation, and upgraded us to a brand new thermostat. Highly recommend this spot. read more

Was very prompt and Constantine the owner came within 2 hours on a holiday. Prompt. Honest. Effective. So happy I called.

I have had the issue with my nest heater not working in my bedroom. I have called the nest company and had a specialist come out and also another HVAC profesional look at it. They have done things here and there but the problem was not fixed- it would NOT work at night or early in the morning when the temperature would drop. I was so desperate (and cold), thankfully I came across this company. After a brief phone call with Konstantin, he was able to come out at 7 AM (!) to catch the heater while it was not working. I was surprised by how easily he pointed out the issue and fixed it. Will Recommend this company to my friends and will use in future! read more

I had a great experience with California AC. Konstantin was a professional -- clearly explained the problem and fixed it. He was also punctual. I highly recommend. I'll definitely be using him and his team in the future! read more

My 30 year old air conditioner was running up my electric bill and not cooling efficiently. I can not afford to get a new system right now. With summer around the corner, I called California AC and heating to see if there is anything that can be done to put off replacing the system another year. Konstantin arrived promptly the next morning and was able to pin point and fix the issues making my system run worse than it should. Unlike other HVAC companies, he wasn't pushing to sell me a new unit despite it being super old. He was pleasant, professional and understanding to my financial limits and immediate needs. I highly recommend this company. I will eventually use California AC for full system replacement but in the meantime I'm grateful to find someone trustworthy to service my current unit. read more
