HVAC reviews in San Ramon, California

Andrew was super informative, very kind and explained everything he was doing. He didn’t upsell me on anything. I will definitely be calling him back for future services on my hvac or even other big appliances

Really appreciate the experience we had with Adrium.service solutions. Andrew was very clear and honest with his work. He explained everything patiently and took his time to get the work done.
I liked that he did not try to mint money by using any scare tactics.
Would highly recommend him.

He was punctual and polite and kept me in the loop of the work he was doing. Thank you.

I had an excellent experience with Adrium Service Solutions. From start to finish, the team was professional, courteous, and highly knowledgeable. They showed up on time, diagnosed the issue quickly, and explained everything is a way that was easy to understand. I highly recommend them to anyone looking for reliable HVAC services.

Awesome service and Andrew is very knowledgeable about all appliances in our house. He fixed the broken compressor, helped us with the warranty part and had it fixed and running in less than 3hrs. This was a big job with special equipment to fix and Andrew worked on a Saturday of a three day weekend! ADRIUM and Andrew will now be our GOTO repairmen!

I love working with Andrew! Very prompt, reliable and honest! He is very good and detailed about explaining the issue and will always give you the most cost effective solution. Would highly recommend them!

Our GE refrigerator's lights stopped working. Then our water filter stopped as well. I called Adrium and Danny came out. He was able to diagnose the problem as being a faulty switch. He ordered a new one and installed it a few days later. Not only did the lights work again but our water filter system did as well. What a relief! Five stars!

My refrigerator stopped making ice and wasn't cooling properly, so I contacted Adrium. They were able to send someone out immediately. Danny, the technician, quickly identified the issue.

Andy also provided excellent service; he followed up with me to ensure everything was working correctly and even called to inform me that I had accidentally overpaid. His honesty and professionalism were truly appreciated.

I am very satisfied with Adrium's service and would highly recommend them for any appliance repair needs. Thank you!!

This was a great experience and excellent service. I needed a condensor moved for some backyard work and he was able to come same day and help me out. Very knowledgeable and gave me great recommendations for the future.

We had Andrew come over to inspect our HVAC and refrigerator. He provided outstanding service, stayed to inspect things for over 45 minutes and in the end, he recommended no repairs and said everything is in order. He was punctual, professional and very honest. Highly recommend him!

Andrew was very knowledgeable and professional. He serviced our HVAC and also our Subzero freezer and did a great job getting them to optimal condition. He was practical and honest about what needed to do done. He was very responsive throughout and on time. It’s rare to find someone so professional.

Outstanding experience from start to finish. The HVAC technician arrived on time, diagnosed the issue quickly, and repaired the system efficiently. Pricing was fair, communication was clear, and the work was done with great attention to detail. I feel confident using this company again for maintenance and future repairs
Thank you

Rating: ⭐⭐⭐⭐⭐

We had a heater making some truly scary noises, so we called ADRIUM because several friends highly recommended them. I’m so glad we did!

Andrew (who I believe is the owner) was out here incredibly fast. He was both friendly and professional, and what I appreciated most was that he took the time to explain all our options. He clearly had our best interests in mind and there was absolutely no pressure to upsell — just honest, considerate service.

It’s rare to find this level of transparency and personal care these days. I highly recommend ADRIUM to anyone needing HVAC help!

I want to say a big thank you to ADRIUM SERVICE. They installed a mini split system for me and did everything very carefully and professionally. Everything works great. I’m really happy with their service and highly recommend them!

David came to repair my home in Dublin. He was very professional and found the issue quickly. Being an electrical engineer, I could see that he is technically qualified to do the job.

My Refrigerator has problem with cooling . I have contacted James (Volta hvac) and he has timely shown up to find out the issue with out any cost. He has taken all precautions of covid and found the root cause efficiently and replaced ciricuit/control board. Part cost and labor charges were very reasonable and Happy with service. He has detailed service items and regular maintainence items for fridge. THANK YOU JAMES!

It was a hot Saturday and of course my A/C broke. I had little hope of getting an appointment within the next week but based on a quick Google search landed on Volta's website and put in a request. Within minutes Ralph called me and set an appointment for the very next day (Sunday morning)! Then I got a text from his partner James who said he could be there within 7 minutes (this was Saturday late afternoon!!!). He showed up promptly, super courteous, made a very quick assessment and promised to come back the next morning. Texted me again the following morning (Sunday) and fixed my A/C. He explained everything he did and why, taught me some thing that I had no idea about and now I have cold A/C and could not be happier. Rest assured that next time my HVAC or any other appliance breaks, I am calling Volta pronto!

Slava Ukraini!

I contacted Volta through Thumbtack. Received response on time. They were able to schedule appointment in 3 days. James (the technician) was able to figure out the issue with washer. Provided quote after diagnosis. Happy with the service.

David did an extremely through job of analyzing the wiring between the furnace circuit board, thermostat and AC compressor & capacitor to locate the problem that was causing my AC to malfunction. I recommend this company to anyone who wants a skilled technician at a reasonable rate.

Volta's team installed a new Thermostat which needed new wiring from the attic. They did it very professionally. Also did service our Dryer unit which was malfunctioning. We were a very satisfied customer.

Wow! David was amazing!!!! He came perfectly ON TIME which is huge for me. Then he was able to diagnose and fix my washer within the hour. They gave me same day service on a Saturday. Thanks! This place is the best!

so far I used VOLTA HVAC 3 times in the last few years. My experience has been very positive and I would use them again any time. They diagnosed the issue very quickly, ordered the needed parts and fixed it in less than 24 hours.
