Kao was super helpful in answering all my questions, doing a detailed assessment of my HVAC system, and pointing out some good things to watch out for in the future. I appreciate his honesty in telling me what I needed to fix now versus what could wait. He really knows his stuff and I would suggest him to anyone looking for a good HVAC specialist. Thanks Kao! read more

Kao was great! He came out to take a look at our old, old AC unit and made some recommendations. My husband and I decided to go ahead and get a new unit and Kao came out the following weekend with another worker and were finished within a few hours. Superb service and great customer service! read more

I wanted to follow up with an update. Climate Solutions offered very costly repair options, even provided a price sheet with fixed rates before even looking at our unit. He never even went into our attic to service the entire unit, never checked the filter. We paid another company to come out. The repair was $225 and they serviced the system which included the filter and attic. It has been running great for months now! We save thousands of dollars by showing Climate Solutions the door. read more

I'm 100% satisfied with the quality service Kao - Climate Solutions and his crew Deione and June have provided. They were very professional and knowledgeable. They have to replace the whole system HVAC/duct. Their installation was top notch and their price was the most reasonable compared to other companies that I've checked. I absolutely recommend Kao / Climate Solutions, outstanding warranties for parts and labor. He actually do the work. read more

Just like many other clients have said Climate Solutions is outstanding! I wish I would've called them before spending money on a new thermostat. My heater was blowing out cold air and I was freezing. I contacted two other companies and they had nothing within weeks. I contacted CS and he came in the next day. It was an air vent that had come undone probably from the roofing guys that worked on my solar panels over the summer. Not only did they fix the issue but also inspected the heater and fixed another pipe that was already loose and was leaking water. He took pictures of it all. I am extremely satisfied with their service and highly recommend them. read more

Kao was very responsive and came out quickly to diagnose my malfunctioning heater. He was profession and communicative throughout the process. read more

Kao provided excellent customer service. He responded quickly and the pricing was easy to understand.

Great Service! they were able to accomodate even if it was late and they had a busy schedule, would definetely recommend. Thank you and until next time read more

Kao from climate solutions was so helpful, he fixed our AC, which is 28 yrs old, without having to replace the entire unit. He completed the repairs quickly and was easy to keep in contact with for scheduling the repairs. We would definitely recommend his services to anyone with HVAC needs! read more

I want to give a shout out to the owner of Climate Solutions. Our AC went out yesterday and when I got home my house was 92 degrees. I called the service that did our last service and they said they could come out on July 30. I called another big company, was told they would call me right back, and didn't hear back from them at all. I then called Climate Control and the owner came out at 9:15 p.m. and fixed my AC. He was professional, friendly and knowledgeable. It took him about 30 minutes to figure out the problem, fix it and then write up his invoice. I would totally call this company again and would also recommend them to anyone who needs service. Brenda B. read more

We contacted several vendors on yelp (4 stars and above) and some without even looking at our furnace gave us outrageous quotes. Other vendors were okay but didn't ask the questions Kao from Climate Solutions did. To make sure he provided us with a proper quote, Kao even scheduled time to come out again with Balthazar to crawl up into a very tiny space. Balthazar is very flexible I am guessing because my attic is small! Kao provided the quote, scheduled some time and was out here a day or two later. Both men installed a new AC unit in a couple of hours. Both men were very courteous, professional, and explained all the details that were needed. Overall, excellent service, fair pricing, and fast. I am recommending these guys to a friend because it was such a pleasant experience. read more

I contacted Climate Solutions because I had issues with my thermostat. Kao came down and inspected our thermostat, and it turns out that it did not need to be replaced. I thought it was broken, but actually, the A/C just kept going back to the default program. He showed us how to bypass the program and explained everything very clearly. He was very kind and did not try to upsell any services that we didn't need. He showed us how to use the thermostat, and I am super grateful that our issue was fixed. Kao's service is exceptional. He arrives on time and gets the job done. If you're looking for any HVAC services, Climate Solutions is the best choice! I highly recommend them. I picked Climate solutions because they had high reviews and the reviews were right! I will definitely contact them if I ever have any more issues in the future. Thank you very much Climate Solutions! read more

Kao showed up on time to our schedule appointment. He was very informative on the reason for the breakdown of the exterior condensor fan was due to a faulty capacitor that caused the breaker switch to fry. He replaced the capacitor and installed a new power cut-off with fuse because that was broken as well. He also replaced the breaker switch at no charge. This guy was great and would recommend his service. It helps when the repair person explains what he is fixing and why. read more

These guys are fantastic. Kao is very straight forward and honest. He gave us a great price on our package. The install was faster than promised. They even replaced a duct that had been smashed by the previous repairman for no extra charge. We will definitely use them again. read more

We needed to disconnect our AC for landscaping at the last minute. Kao responded quickly and showed up the next day to remove the AC. He even drove all the way down to San Jose from Hayward to get a key to unlock the AC. We are very happy with his service and will be recommending him to our friends in the future. read more

Just had the service from Kao. He was awesome. He was very fast in responding to my quote request, confirmed his arrival before coming, and did a very thorough inspection job. He explained very patiently how furnace works and how air flows, and why certain noise came from the roof when heater is on. Very very good job. I am very happy with the service from his Climate Solutions. read more

My Nest thermostat was glitchy and would lose power and then would randomly turn itself back on. Kao arrived at the scheduled time. I like that he wore shoe covers while working inside my house. He tried one solution before having to move to other options. Very professional staff, explained everything, and showed me video of the problem. I would definitely use them again for future heating/air jobs. read more

I highly recommend climate Solutions, was on time . Very friendly, he knew the problem right away and fixed very quickly. Very honest guy and I appreciate that! 5 stars read more

Came across Climate Solutions from a referral. Kao arrived on timely manner, made the necessary assessment and was able to fix our AC unit on the spot! He was very responsive and honest on what needed to be done, this was a relief for us! We were so lucky he was able to accommodate us, especially having to service during the peak heat wave time. We will definitely use Climate Solutions again! read more

This was one of the best interactions ever that I've had with someone working in my house. He came in, checked what I asked, gave me my options as he could see. Answered my questions with not one ounce of pressure and when I said I would have to see about what I could afford to have done, just said ok, took the payment for the inspection and asked me to call when I had anything else. This was awesome. Didn't treat me like a stupid homeowner, just talked like I was someone who didn't have the skill (which was obvious) that he did. Definitely a good interaction. read more

Kao is great. We perform HERS Testing for Climate Solutions and never have a problem getting their systems to pass.

These guys are great! Quick response time, a full explanation of products and services, very fair quotes, and installation were "as promised." Friendly, knowledgeable, on-time, and very clean best describes their work ethic. I highly recommend Climate Solutions for your heating and air-conditioning needs! read more

Disappointing experience. Really wanted to hire Climate Solutions and support a local Elk Grove business. Called several times, left voicemail and even tried contacting them through Yelp. Never returned any messages or phone calls so I had to hire someone else. read more

Dec 1, 2018 I have never written a review but just had to let everyone know about Kao from Climate Solutions. Not only is he punctual, reasonably priced, gets the job done, very informative when asked questions, he is most importantly HONEST! So for your heating and air conditioning needs call Kao at Climate Solutions at 510-639-9710 you won't regret it. Rosie read more

Kao is the man!!! Called him late last night when my Normal air conditioner guy flaked on me. Kao was able to get me a next day appointment. He fixed my a/c under 10minutes. (Blown fuse). I highly recommend this guy again. Thank you. read more

What a relief!! I got a $2K quote from another company to fix my furnace and I decided to get a second opinion. Kao came out, addressed the core issue and got me up and running at a fraction of the previous quote. They took the time to explain the issue, showed me video (on their phone) of the problem. No hard up-selling here, just honest problem solving. By not trying to up-sell me on unnecessary repairs, Climate Solution just gained a customer for life. Thank you! read more

Kao responded within an hour of my messaging him and quickly confirmed an appointment for the following day. He arrived as has promised. He figured out the heating issue quickly and explained it clearly. He gave us a reasonable quote forthe repair and so we had it done right there and then. Job completed within an hour. We highly recommend him! read more

Kao of Climate Solutions serviced my HVAC recently. He did a fantastic job and saying that I was satisfied with the results would be an understatement. He went out of his way to explain each step he took. He even went to make sure that the area would look neat. I was very much impressed with his attitude towards his work. I certainly would recommend Kao to my friends who would need his services. I will continue to have Kao service my HVAC. read more

If you are looking for someone who likes to do price games like at the car dealership and is looking to see how much they can get from your pocket and has lack of transparency, Climate solutions and Kao is the perfect match. All the specs of the hvac replacement including photos were sent to him from the beginning, then when he went to job site, he started to raise the numbers way above the range he e-mailed days before (thousands more) for exactly the the same equipment and job. Then when his changes started to be questioned Kao started to come up with excuses and greedy sales techniques. About 2 hours wasted on this, very dishonest and unprofessional, with no word at all, and did not even provided the quote he claimed he has going to provide. Not recommended at all for new installs. 1) Kao's HVAC replacement estimate prior to sending him the parts numbers: "What is your budget you have in mind? Typically these jobs are anywhere between 7-12 K depending on tonnage and efficiency." 2) After clear and detailed HVAC replacement specifications with part numbers etc..were sent to Kao the price range jumped: "I am really tight in schedule right now however if you're looking for a 97% furnace/ 20 seer ac, that's going to push it close to 12-15k. Especially if we are changing the zone board and damper system and converting from an 80% to a 97%. " 3) After Kao went to the job site price range jumped by thousands more, and started to charge again for work that was already included in the job specifications which he used to provide the 12-16k price range. If you want to deal with Kao's dealership like price games, he will be the perfect match. Kao wanted to see the quotes I received (typical of car sales / price games tactics). I told him just an approximate number, about 8 quotes (meaning quotes for repairing existing unit + quotes from hvac brands no longer interested + very few quotes from the brand I want) . Not sure what was his point about the number of quotes. If he were a Yelp user he should know that when a quote request is made via Yelp, yelp allows users to send the same request to multiple contractors at the same time. It is so clear that Kao / Climate Solutions hvac installation replacement prices are way too high, if that's what other yelps users are looking for, Climate Solutions is the perfect match and it will be very costly. read more

I called climate solutions to get a second opinion for our broken ac unit. Kao was very responsive and was able to come out right away. He and his colleague were very thorough checking the problem. We made the best choice going with them because they were able to install a new unit efficiently and professionally. Highly recommended! read more

Kao was able to come to my house to fix the issue with my HVAC at very short notice (next day!!) which really saves my life! He was totally professional, very patient and explained everything I was unsure about HVAC system to me and also helped me set the thermostats. I would high recommend him if you live within their service area! read more

Kao is just great! Very responsive and thorough. He came out to check why our furnace kept turning off and on. I thought we were having an issue with Nest but he explained that our contractor, when he built the new house, didn't use big enough ducts. He fixed the issue and didn't even charge us because he had to reschedule the appointment. I didn't think that was necessary at all but just underscores Kao's great customer service. Will definitely have him come out for all our furnace and AC maintenance/repair needs. Thank you, Kao!! read more

this is an update on my prior review of Climate Solutions. Kao and his associates have been working with me for over a year to keep my AC running. This is not because of them but because of me. Now that I was ready to move forward with my major repair, Climate Solutions took care of me and my family in a very professional and timely manner. Over the past year, they always replied to my service request on time if not earlier than I requested, knew exactly what I needed to have done and always friendly. On top of that, he always remembered me and my situation/needs. I think that's rare these days, not being treated like a nameless face in a crowd. Having dealt with other HVAC companies and having a personal history of working in contracting, I can tell you Climate Solutions is worth every penny just from a dedication to quality stand point and genuine concern. Even if you can get a lower quote for your job, I'd recommend you consider what value you would place on work ethic, timely communication and service. Then you will no doubt call Kao. He guarantees all his work in writing but I have a suspicion you wouldn't need it, he'll just take good care of you. read more

There are no complaints from us. Kao was friendly and explained everything that he recommended to be done and why. He e-mailed us a quote to see if we agreed and once we did, he scheduled an appointment and came and finished it all in one day. Him and his employee were careful and didn't leave a mess behind when they left. Oh and the company van looks pretty nice too! Not that it's too relevant, but having a well-kept, marked van makes the company look more professional, like they take pride in themselves. read more

Kao is the best! He replaced our heater when other businesses side you would have to wait until after winter. And he installed an A.C. unit. Exceptional customer service. read more

I was extremely impressed with the outstanding job that Kao did to fix my broken air conditioner. He was very professional and worked very efficiently and quickly. He successfully troubleshooted what was wrong with my air conditioning system and replaced one of the broken parts. I am so glad I contacted Climate Solutions because they did an exceptional job. I would definitely recommend calling his business and especially asking for Kao. read more

Kao was very professional. He was on time for the two estimates at my house and gave me some options that I was not awared of. During the installation, Kao took his time to make sure everything is done properly and all the connections are properly and securely made. He cleaned up all the area very well at the end of the job. We couldn't be happier. Highly recommend. read more

Lao is very professional and honest! Our A/C went out, and he came right away and found a LOOSE WIRE! Wow, what a great company!

Never trust the appointments made with this guy. I saw his Mercury news ad for the $88 furnace tune-up and made the appointment with him. He called and canceled his visit the morning of the appointment due to family emergency. OK, I took his excuse and scheduled another appointment with him one week later. I called him an hour before the appointment to confirm his arrival time, he told me he was on a big project and can't make it. He didn't even call me to let me know and his excuse was he is a ONE-MAN company so he sometimes just drop the appointment !!! It is not worth to waste your time to wait for him because you are not sure he will honor his commitment !!! Now I saw a new ad. on Mercury news that he is now raising his price to $98 for the service. Maybe he just too busy to keep up. Good luck if you respond to the ad !!! read more

Kao and his team are very professional and thorough! We recently had our air ducts cleaned and AC tuned up. Kao and his team arrived on time. They were careful with keeping their work area clean. They were knowledgeable and shared their progress with me while they were working. I'm very happy with their work. I will certainly use them for any future HVAC services. read more
