Yesterday I discovered my AC was blowing warm air, so I came to Yelp to find an AC company that was open on Saturday. I found Cronus Service that had good reviews and was close by. Alex showed up within an 1 1/2 hours to fix it. He was very professional and friendly and explained everything we asked about. He is highly competent and knowledgeable and had it fixed in no time. We were both impressed with him and his work. The price was lower than we expected too! Highly recommended!! read more

would definitely recommend. they were quick to come out and give an estimate, very responsive to my questions, and provided a detailed explanation of what my costs would be depending on what options i chose. the person who came to do the actual repair was friendly, considerate of keeping the work area clean, and even showed me what failed on the original part. read more

I highly recommend this business. From the very beginning, Cronus Service gave me a fair and honest price for the installation and offered a convenient financing option. After we agreed on everything, they prepared the full system design and handled all the paperwork needed to apply for the SMUD rebate. They installed the solar panels and Tesla batteries in just one day, and the inspection passed with no issues or corrections. The entire team was extremely professional, knowledgeable, and very polite. Everything was well organized and clearly explained. I'm very happy with the result and would confidently recommend them to anyone considering solar or battery installation. read more

Our house had an old breaker panel that was full. We bought a Leaf and were using the 120v charger it came with but it would often cause the breaker for the garage circuit to trip. We got by for a while by making sure we kept everything else on that connection off but it would still occasionally trip. The solution Cronus provided was to install a new breaker panel (besides the old panel not having room for another breaker, our existing breaker's were obsolete), new wires from the panel to the garage, and a high voltage universal charger. So now our charger has its own dedicated lines to the panel and its own breaker. Sergei and Ivan came out the first day, Ivan and Roman finished up the second. They were courteous, competent, and professional. We were only without power for part of the first day. Everything Cronus worked on has been great. We are enjoying not having the breaker trip, but also being able to have the garage or driveway lights on while charging our car and the security of knowing we are not overloading our house wiring. We are glad to have used Cronus for this work and plan to use their services again in the future (our water heater is very old). read more

They were definitely the most honest out of all the hvac quotes I gotten. While I had lower quotes, lower price does not mean quality work. I think they provide excellent work (they warrant both their work AND parts!) while and the price is very competitive. I met the dad who owns the company and the son who installed my parts. So this is truly a family business an overall I would hire them again and I would 100% recommend them. They were the only one not trying to upsell me while offering detailed quotes and warranty assistance read more

They were able to book us for an appointment quickly and Alex came very promptly. He took care of our issue and got our AC running again in no time! And plus because it was minor and he just needed to put tape on a tripped circuit, he said he will not have to charge us. We really appreciate the honest service! We also got feedback on our AC system and looking forward to working with Cronus again! read more

Fixed 2 issues with our hvac and did a great job. Would highly recommend. Thanks guys!

Great company, communicated quick and easy, Alex D was out here in less than 3 hours and got my A/C working without trying to sell me anything extra. Will return to them again if something comes up with my A/C. read more

A/C was somehow blowing warm air, called Crown to schedule an appointment. Alex showed up on time, as promised, and was able to quickly troubleshoot the issue. A/C is now working as intended. This is the third time in the past few months I have called Crown, each time they show up on time, are very organized, efficient and very competent. Highly recommended, very highly recommended, indeed. PS. Not sure why my first review, back in late January has not posted. Alex showed up back then after hours to troubleshoot the heat pump, even in the darkness. read more

We had been looking at the temperatures coming up for the next few days when suddenly my husband realized that our a/c was not working. He noticed that the a/c fan was not moving. I tried to call our previous repairman and his number was out of service. Cronus was the first to respond to set up an appointment for us. We could not be more pleased with the work that Alex did. He explained things to us carefully and worked quickly to resolve our issue to cool the house again. He also discovered something that someone else had done and will come or send someone tomorrow to repair that too. We could not be more pleased with the price and the thoughtful service. read more

Alex diagnosed and fixed the problem quickly and efficiently. He explained the issue and told me things to keep an eye on in the future.

I Called Cronus Service for AC today, the person responded "Maria" was extremely friendly and professional. I needed to have my AC checked and Refrigerant added. Appointment set, and the technician came actually much earlier and completed the job and turned on the AC to make sure the AC was working properly. Bravo, thank you, I am happy and my Tenant is happy! Thank you for the quick response and great service. Best Ray read more

Cronus Service - Great job - Heating & Air Conditioning/HVAC Near Me - North Highlands, California

AC went out on a crazy hot Sunday (105°) and these guys were the ONLY ones willing to come out same day. Most places don't even have techs on Sunday -- so huge points for Cronus offering it. Honestly that alone is 5 stars. Alex showed up in the 3-5pm window, super polite + professional, even parked in guest parking for my HOA. He explained everything before starting, found it wasn't the capacitor like I thought but a burnt connector to the power supply, swapped it fast, and had cool air back in minutes. House was already over 80° inside so I was sooo grateful. 5 stars, will for sure use again. read more

Cronus Service - Heating & Air Conditioning/HVAC Near Me - North Highlands, California

Alex was great and did a very thorough job. He explains everything and even informed me about possible issues I might have further down the line. They don't pressure you into buying additional items or services and they don't charge to come out to diagnose your system. All other contractors charge $57+ just to come to my house and diagnose the issue. After all said and done, I expected over $500 but it was literally half that. I will be using them next time I have issues with the house HVAC system! Thank you Cronus Services! read more

Had a Tesla wall charger installed. From price estimate to installation, Cronus was exceptional. Quality installation done efficiently. Would definitely use them again for future projects. Thank you Cronus...!!! read more

Our air conditioner went out right before a 105-degree day, and we were desperate to get it fixed quickly. I found Cronus Service and called them late in the evening. To my surprise, they called me back right away and scheduled an appointment for the very next day. The technician showed up on time, was extremely knowledgeable, and quickly diagnosed the problem. Best part--he had the necessary parts on hand and was able to fix our unit right then and there. No waiting, no hassle. Now our AC is running perfectly, just in time for the heatwave. I highly recommend Cronus Service to anyone who needs fast, reliable, and professional air conditioner repair. read more

I was really grateful for Alex's help. Not only did he find the problem and fix it, but he helped me understand the bigger picture with my HVAC, with photos and video, and my options moving forward. He even recommended things I could fix myself if I wanted to (obviously they could also do it, but maintenance can be cheaper if you're able to manage on your own). At the end of the day, as a first time home owner, I was really grateful that I didn't feel like I was being pushed to buy things I didn't need, and that I understand better what to do moving forward. Thanks Alex! read more

This review is about replacing my 23 years old gas water heater with heat pump water heater. 1-They provided a fair and competitive cost estimate. 2- Their quote was straight forward, all inclusive, and without any ambiguity which didn't require any change order to get the job done. 3- They always responded promptly, did what they said they'd do, and finished the job on time, on schedule, and w/o asking for more money. 4- The installers, Aleksandr and Roman were nice and professional people. They answered all my questions and addressed my concerns read more

Cronus Service - Alex next to my thermostat - Heating & Air Conditioning/HVAC Near Me - North Highlands, California

We've used this company a few times for our Samsung digital French door refrigerator, which unfortunately keeps having issues. I'm so glad I found them! They charge $50 for an estimate, and that amount goes toward the repair if you decide to move forward, which is really fair. They've always been professional--quick to answer calls and prompt in scheduling a technician to come take a look. Overall, I'm very happy with their service and reliability. read more

Very poor decision on my part choosing Cronus installing a new HVAC rooftop mounted ! Contract amount $13K. Within in 60 days, roof leaked water below new HVAC installed by Cronus and continues to leak after rain days. The leaks were confirmed by 2 outside inspectors showing definitive pictures of water intrusions/leaks into attic and living area. 1 company is a mold inspector (Mold Inspection and Testing Co), 1 is a remediation company (Reactic Restoration Co) dtd, April 30 and May 1, 2026. Since water leaks continue, tenants on my property had to terminate lease due to compromised habitability of house and moved out May 1, 2026. Beware! Denys, I e mailed Cronus Sunday, May 3 and again May5 requesting an amicable conversation/resolution with no response from Cronus. I'm open to discussion/resolution if you're amenable. Please advise if you'll be available to discuss tomorrow, Wednesday, May6, 2pm. read more

We had an excellent experience with Alex. He was professional, courteous, and took the time to clearly explain the issue with our A/C, which turned out to be a broken capacitor. He had the repair done in under an hour, and we were incredibly grateful to get it resolved so quickly on a hot summer weekend. The estimate was very reasonable and aligned with our own research. read more

The air conditioning in my rental property wasn't cooling, I called for service around noon. They scheduled a technician, Alex, to arrive between 3-5 PM. Alex called while he was onsite, provided quote and explained that the fan doesn't blow. By 5 PM, he had replaced a faulty capacitor, and the AC was working perfectly again. I'm very happy with the entire process and will be a future customer. read more
