    I have been waiting 4 months to write this review to see if I would have another HVAC issue and so…read morefar it's been smooth. I have been really skeptical of all HVAC companies in the past 5 years. I have been burned by so many HVAC techs and wasted so much money. 4 different companies went through with different shadiness levels giving me different answers for the same HVAC issue. Every company kept telling me my freon was low and i most likely had a leak. One company even told me to just replace my brand new system cause "it was from China" The Jaguar tech (Jeff) definitely gave me some disappointed head shakes at previous work but was the only one to truly put his head down, work, and diagnose the root cause of the issue. He checked every part of the system before he gave me an answer on what he believed was wrong. After the diagnosis he detailed every part of the HVAC unit (and attic unit) and explained to me what he was looking for, what he found, and what he believed was the answer. I never felt like he was up-selling me. It wasn't even a freon issue to begin with and the filter drier needed to be replaced. After another visit and a 4 hour procedure my HVAC unit has been running smoothly all Summer 2026. I will seriously only call this company from now on.

    Setting up the appointment online was super easy, and they were able to send a technician out…read morewithin two days. They sent a helpful reminder and completed the task in under an hour. Since I wasn't at the property, I had asked for a quick update. The work was done so fast that the invoice popped up on my phone almost immediately! The only reason I'm giving 4 stars instead of 5 is that I didn't receive a call with an estimate or breakdown of what was needed before the work was performed. Overall, though, it was a very quick and seamless process.

    My Air Conditioner was not cooling my house's hot interior. When I called AirMech, I was offered an…read moreappointment the next day (sooner than their competitors). The service technician Christian arrived on time and courteously introduced himself and his service procedure. He used a handheld meter to measure pressures and other important data about the unit's performance. He showed me the results on his meter: a loss of pressure, probably because of a coolant leak. He laid out my options and answered my questions. After getting my approval, he replaced the missing coolant and added a dye kit that would help find the leak. He also mentioned the dye kit included a sealant that might close up any small leaks. After adding the coolant and dye kit, the HVAC unit quickly brought interior temperatures down. Short-term problem solved. Christian explained that AirMech offers a maintenance plan that I should consider. It pays for regular inspections and provides a 15% discount on the work he had just completed. I opted in. The money I saved that day will more than pay for a whole year of the maintenance plan. A couple weeks later, I called AirMech again to have them inspect the lines to look for leaks. Christian was my man again. He arrived bright and early and performed a visual check in the attic. Then he hooked up his meter to the outdoor HVAC unit. He showed me the results and interpreted them for me: all readings are in the "ideal" range. It looks like the dye kit with sealer did its job. And because I had opted into the maintenance plan, there was no charge for the visit. Long-term problem solved. AirMech's staff operated with professionalism and integrity. I will call on them for my future HVAC needs. And I hope I get Christian again!

    I cannot recommend AirMech Heating and Air enough! Ali and his entire team are always exceptional,…read moreprofessional, and incredibly thorough with their work. They take the time to explain everything, pay attention to every detail, and most importantly, they make sure the job is done right the first time. This is actually the second major project they've done for my family. They previously replaced the entire HVAC system in our old house, and because of the excellent experience we had with them, we trusted them again for our new home. Once again, they exceeded our expectations. Their workmanship is top-notch, and their customer service is outstanding. A special thank you to my regular technician, who always ensures our system is running perfectly and efficiently every single time. It's reassuring to have a team that genuinely cares about their customers and stands behind their work. Thank you, Ali, and the entire AirMech team, for your honesty, professionalism, and dedication. I highly recommend AirMech Heating and Air to anyone looking for reliable and high-quality HVAC service! You have earned a customer for life!

    Two word review: Honest, Responsive…read more This is my THIRD consecutive 5-star review for Rocklin Heating & Air. In the last 10 or so years in the area I've called RHA, one other place because they could get me to faster - had a bad experience, waited for RHA had an amazing experience, and decided they're going to be my ride-or-die for HVAC. I called them at 7am and by 11:30am their tech had fixed and tested everything and off to help someone else. Yesterday was the start of a heat wave and ... our AC unit quit on us. I called RHA as soon as they opened this morning at 7am, asked for Joe in particular, and they gave me a window between 10am and 12pm. Joe texted ahead of time at 10:30, diagnosed the blown capacitor, swapped it out, cleaned things up a bit, tested the coolant, answered a bunch of questions, and was on his way in just under an hour. The diagnostic was $129 and the capacitor was $186 today. By a complete and total coincidence, I had been running some experiments with home temperature sensors for the last week. You can literally see on these pictures exactly when the AC unit stopped working - and when RHA saved our bacon. The "other" place I called years ago only had a $79 diagnostic charge, but wanted to rip out and replace the entire HVAC system - and claimed we were taking our lives in our own hands by not getting it fixed with him immediately. Joe and RHA took care of everything for the diagnostic. Yeah, you can probably find someplace to charge you less for the diagnostic or maybe less for the part, but when your house is boiling hot / freezing cold, you want to be able to call on someone you can trust to help you out - and not take you for a ride.

They were able to get someone scheduled immediately for the next day! So, earlier this morning, our technician (Frank) called with a heads up for his arrival and showed up right on time. He was very polite and got to work right away. Turned out to be a bad capacitor. Frank had everything we needed in his truck and was able to swap it out in no time. Now our A/C is working great again!! Thank you so much! Glad I found you guys on Yelp!

    Our AC stopped working late in the afternoon on a 100-degree day, so I reached out to Cronus…read morethrough Yelp. I had used them earlier in the year for a minor inspection and remembered how helpful and honest Alex D was. At that time, they told me the work I was considering was not urgent, even though it meant I did not move forward with the project. They responded very quickly and had Alex D. at our house by 8:30 that evening, only about an hour after I contacted them. Alex was excellent. He found an issue that had somehow been missed by another HVAC company that had been performing routine annual inspections on our system. He was courteous, respectful, informative, and very genuine throughout the entire visit. He explained what he was seeing in a way that was easy to understand, answered all of our questions, and made sure we were comfortable before doing any work. We never felt pressured or like we were being sold something we did not need. Alex clearly takes pride in his work and in making sure the customer understands what is happening. After both experiences with Cronus, they have definitely earned our trust and will be the company we call moving forward.
