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

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

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

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

Alex D was on time and did a great job explaining the issue, was professional and was quick to repair the problem. Sent photos of the before and after. No complaints with the company or the technician! Estimate #3668 read more

10/10 Alex came quickly and gave a fair estimate did a great job addressing my heater problem and quickly with parts already on hand. He was very professional. I really could not have asked for more than I received from this company. I would definitely call them for my next service if I ever need anything more. read more

Cronus Service - This is Alex with my now working heater! Should have called sooner - 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 - Alex B did a great job quickly repairing my broken AC unit. - Heating & Air Conditioning/HVAC Near Me - North Highlands, California

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

My AC went out and the forecast says it's going to be 105 degrees in a couple days. I called Chronus and they had Alex at my house in 3 hours! He found the problem in 30 seconds! And he had a replacement capacitor in his truck. Amazing! I thought it would take a week or more. 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

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

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

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

We were referred to Cronus because our furnace was not receiving any power. Alex D. came out promptly during the expected arrival window. He was extremely knowledgeable and was able to diagnose the problem and offer two options to fix the issue with transparent pricing and pros/cons on each issue. After selecting an option, he finished the work in a timely manner and was able to confirm that the fix had worked. I was impressed with the service provided by Cronus and Alex D. in particular and would definitely use them again! read more

Exceptional HVAC replacement - great price, creative solutions, and flawless installation After thorough research and multiple quotes I selected Cronus to replace my old 5 ton AC + gas furnace + Smart Vent (fresh air damper). The initial response time was very impressive - within minutes of submitting a request for a quote I got a message back and then a call to schedule someone to come out an hour later. When Alex arrived I explained that I wanted a variable speed fully communicating system, which I'd learned from a SMUD webinar was the most efficient type of system. I also wanted the system to be eligible for the SMUD and CA rebates as well as the soon to expire Federal tax credit. He pointed out that Daikin is likely the best option for me and would be cheaper than most other comparable systems. This matches up with SMUD data that showed Daikin to be the most popular system that goes through their rebate program. As the Smart Vent isn't compatible with variable speed systems, Alex suggested a heat recovery ventilator (HRV) which would be much more efficient and exchange enough air to keep CO2 and VOC levels in acceptable ranges. I received a quote quickly, much faster than other companies, and it was also the most comprehensive. I had asked him to quote an optional additional duct run to a room that was added and lacking a vent. I was surprised at how cheaply this could be done, especially as other contractors were telling me it likely wasn't possible. Many of the other quotes I got wanted to run a new lineset or 220v to the attic but the Daikin didn't require that. Likewise other contractors wanted to cut new holes in the roof but Cronus found a way to re-purpose the old vents from the smart vent and gas vent so that no major changes were needed. After signing the contract, in late October, Cronus got the permits and came to install the system days later. Ion and Aleksandr arrived to do the install and laid out drop cloths along the entire way and were very courteous and professional. Over the next 3 days they got everything installed and configured. It's only been a few days but I'm very impressed with the system. It is dramatically quieter - I can't really tell when it's on other than the whole house feels the perfect temp all the time now. Cronus will be coming back in the spring to confirm everything is operating properly and show me how to maintain the system. I can't recommend Cronus enough. Even if you're getting multiple quotes like I did, make sure Cronus is one of them - and honestly, if you only have time for one quote, make it Cronus. They were responsive, knowledgeable, competitively priced, and delivered exceptional work. read more

Cronus Electric was very responsive and their pricing was attractive compared to their competitors who quoted thousands more. What made me choose Cronus of the six companies that I received quotes from was that they were ONLY ones that physically came out to the house to assess. Alex was knowledgeable and explained everything I needed to know in order to install my EV charger. Other companies just asked for an address or wanted pictures/videos. How are you supposed to get a solid assessment without eyes on? Plus they're local to my house so supporting a neighbor was a plus. I totally will recommend Cronus to others for their electrical needs. By the way, I forgot to ask for military discount but for future customers (especially veterans) that's always a positive! read more

Amazing service.... called 7 am on Saturday morning due to our A/C not blowing cold air. Recieved a text message with-in 15 min. After reaching out to them. They said they were able to service us between 12pm-2pm same day. Alex D. was very communicative all morning letting me know he would be coming closer to 2pm. He was very cordial and right away diagnosed the problem. He answered every question and gave me tips to add longevity to my a/c system. The estimated price was very reasonable. He got us back up and running in 30 min. It was the first 100+ degree day in Roseville. Amazing service and value. I won't go anywhere else for services. They also do electrical, plumbing and construction. You got a return customer!!! Thank you Cronus and Alex!!!! 5 star service highly recommended!!! read more

Our air condition went to crap in the heat and our kids were suffering in a hot home. Our air conditioner wouldn't go pass 77 degrees in a 100 degree weather. Our ceiling fans and standing up fans were on but blowing around hot heat. It felt miserable in our home. We needed to contact a technician and started an air conditioner project on Yelp. We came upon many companies but this company responded first and this company had very excellent reviews. Company said there was a guy in his way within minutes. Wow, that was incredible. What a life saver these guys are. Technician, Ion, arrived to our house and went directly to work at 8pm at night time. He's very honest, hard working, and very helpful when questions are asked. You can tell Ion was very passionate about fixing our air conditioner. I'd recommend this company and technician Ion. Company was very responsive and first one to respond to my request. Now our ac is blowing cold air again and feeling nice. read more
