HVAC reviews in Corona, California

Kevin did a great job on the two occasions that I called him. One involved a unit replacement and the other a repair that has kept us nice and cool this summer. I have no reservations about his knowledge and skill and will definitely call Kevin again as soon as the need arises.

Honest and quick service. Kevin came out within 30 minutes after we called about our capacitor going out. It was of course in the middle of a heatwave so you can imagine the panic. He was quick to repair the issue and we had a good working AC shortly after.

We called Kevin on a Sunday with a non-working condenser. He came over that day to check it out. It was actually a breaker problem and he swapped out the breaker with a spare. He came back the next day and updated some of the condenser components. Great response and he fixed the issue! We appreciated the quick service!

I cold called Kevin and he immediately picked up the phone and was at my house within an hour's time to assess my AC's condition. Within a day, he had a new unit ordered and was back at my house, installing it with his assistant. They made sure to have all the materials on the truck to complete the job that same day.
Kevin is very passionate about his job and offers nothing but honesty and cares about providing value to his customers. He is the only call that you need to make.

Frinj Energy came out to Eastvale and repaired our heater and performed a tune up today. Kevin was honest about our options and did not try to sell us a new heater. We highly recommend Frinj Energy.

When the cold Santa Ana winds blew hard our heater stopped working. I called a company and they promised to come in six days. A friend gave me a phone number, but he is a plumber. But he gave me the number for Frinj Energy and Kevin came in a few hours. He fixed it easily and we were relieved that we didn't have to go to a motel.

Kevin is awesome! Super knowledgeable and patient—he explained everything about our AC, answered all our questions, and gave great suggestions. One of his ideas was to move the AC to the side of the house and upgrade to a slimmer, more powerful unit. It freed up extra backyard space, and now the new AC cools our two stories more evenly while using less power. He’s always on time, provides great service at a fair price—we’re really happy with his work and definitely recommend him!

Kevin and his crew have done multiple jobs at our house, including replacing our air conditioners. Kevin and his team are knowledgeable, their work is impeccable, along with very competitive pricing. We highly recommend!!

Our air conditioner stopped working and we called Frinj Energy for help. Kevin arrived quickly, found the problem right away, and repaired it without trying to sell us anything we didn't need. It's hard to find honest HVAC companies in Eastvale these day, but Frinj Energy really impressed us. Highly recommend them if you
need AC repair.

Kevin came out for the initial service call and honestly I was expecting the usual repair conversation but he took the time to really walk me through what was going on with my system. He showed me exactly why putting more money into it didn’t make sense and how replacing it would actually be the smarter financial move long term. No pressure just straight up facts and numbers.

What stood out was that he didn’t just say replace it and leave. He explained everything in a way that made sense and answered all my questions.

The install itself was super clean. You can tell he takes pride in his work. Everything was done right, looks great, runs great, and the attention to detail shows.

Appreciate the honesty and the quality of work. Would definitely recommend Kevin and the team.

We called Frinj Energy for AC repair in Corona when our air conditioner stopped cooling. They were able to come out the same day, diagnosed the issue quickly, and had our system running again. Kevin explained everything clearly and didn’t pressure us into unnecessary repairs. If you need HVAC repair in Corona, I highly recommend them!

Our clinic HVAC stopped working 1 day after being repaired by another service who refused to come in and check it immediately. We called this business and Kevin in less than few hours showed up and fixed it.
While other service replacing part one after another and charging us for it, he found the problem with high refrigerant pressure and immediately correct it.
Working in over 83 degree inside is definitely unpleasant and he helped when we were desperate.
Price was reasonable and we totally switched our maintenance to this business. Definitely recommended.

Great communication, fair pricing, and excellent service! Kevin and his team did a fantastic job installing our new A/C system. I had already received three estimates but wanted one more for comparison. Over Labor Day weekend, I tried calling several companies—understandably, no one answered. But Frinj Energy did! That gave me peace of mind knowing that if I ever had an emergency over a holiday, they’d be there.

From our very first meeting, Kevin impressed me. He came out personally, looked at our equipment, and immediately recommended the right upgrades—no sales gimmicks, just straightforward advice. He quickly followed up with a competitive estimate, and compared to the other local contractors, his knowledge really stood out. While other companies sent sales reps who couldn’t fully answer my technical questions, Kevin addressed everything clearly and simplified the whole process.

If you’re looking for honesty, expertise, and great service, I highly recommend Frinj Energy!

Cool comfort restored blissfully!

Totally new home and better energy use.

The technician's expertise restored cool comfort in under an hour!

The AC install was easy from beginning to end. I'd totally say they're the best!

The air seems really clean and lovely once they depart. They performed everything swiftly and well. It seems like my neighborhood has a new lease of life.

Damn, good work.

Ricardo does a great job for my clients. Fast service and reasonable prices! I highly recommend him.

Excellent service with Ricardo. Very communicative, friendly, and on time. Knows what he’s doing and explained every step of the way. Helped fix my heater up and functioning again in no time. Would recommend!
