They were able to start work just a week after signing off on the quote, and the work was completed a half a day early. We were very pleased with the crew - all were kind, conscientious, and cleaned up their work areas very thoroughly each day. I'd definitely hire them again for any future hvac work I may have. read less - 1/02/2022

I contacted 4 HVAC companies with good ratings and got pricing for both, including upgrading our old asbestos ducts with new ones. Michael and the Ariston team had the most competitive quotes, and they also installed the best HVAC brand per Consumer Reports (American Standard). Given the Bay Area air quality problems, I also went with a high-end air filtration system that was hospital grade. The crew was on-time, efficient, and considerate - kudos to Alekos and his team for being so professional. After it was installed, the independent test found that it worked with high efficiency and I received a city permit shortly after for our new system. I couldn't more highly recommend Ariston - they are excellent, the best. read less - 8/11/2021

They quickly gave me a quote after coming by and looking over my place. It took them just over two days to do the work. They were professional and friendly. The project went pretty smoothly, and our new system is working well so far.
Overall, no complaints at all. They were great at communication, provided a reasonable quote, and the work took as long as they originally forecast. read less - 5/05/2021

I ended up going with Ariston because of their value, professionalism, speed of communication, and willingness to go above and beyond to ensure we would have no issues with the local permitting office. The work went smoothly, the crew was friendly and professional, and I now couldn't be happier with how it turned out! They were incredibly accommodating and pleasant to work with. Alekos, Michael, and the entire team were very clear communicators throughout the whole process, did top-quality work, and made a potentially stressful project as stress-free as possible. So happy with having fully-functioning A/C now. I cannot recommend them highly enough!! read less - 10/18/2020

After hearing about their different options for us, which were explained in great detail weighing the pros and cons of all the different types of systems, we had them install a new high efficiency furnace and AC unit. It was great to work with a team that took the time to thoroughly walk us through all of our questions from start to finish. They were clean and respectful of our house, indoors and out, even considering the heavy rains that were pouring down throughout the install (furnace closet is located outside!). Ductwork and all of the hardware is all neat and tidy in our cramped little closet. We got a complete rundown of our new Nest thermostat explaining the features and how to best use it with our lifestyle/needs.
I'm a DIY type of guy for most projects, but, I'm very glad I made the choice to go with these guys for this task! read less - 11/30/2018

Eric, Alekos, and team are by far the absolute best that one could hope for in all areas of professionalism, honest advice, and expertise in home heating-n-cooling matters.Before we needed any actual service, we'd connected with them for a consultation on a furnace question. Even though we weren't getting any work done with them at the time, Eric was super helpful and totally non-pressurey in letting us know what our options were.
A short while later when our aging water heater kicked the bucket, we turned to Ariston immediately. We had them replace it with a tankless model and they did an awesome job and were so lovely to work with.
Before, during, and after the water heater replacement, Eric was a constant source of support and he kept us informed every step of the way. When another contractor we were working with at the same time was cutting corners and treating us like crap, Ariston went above and beyond to help us get an adjacent issue related to our gas line taken care of. Eric also handled all of the City of Berkeley's many hoops with grace, patience, flexibility, and a sense of humor. We were actually sad when our project ended since we wouldn't be able to talk to Eric anymore because he's such an awesome dude!
Owning a home is often a pain in the neck: Things break and need fixing all the time. Many if not most contractors are total sheisters, ripping you off and making you feel like crap every step of the way. But not, Ariston -- they are the complete opposite -- a shining light of professionalism, expertise, and happiness. 5 stars isn't enough. They really deserve 10. read less - 7/22/2018

I had a older system that was having some problems with the pilot light consistently burning out and lots of leaks in my system. I called another company previously before talking to artisan and they told me that I needed to replace my whole unit because it was too old. Everything worked I just had a couple of leaks and pilot issues. Long story short I called artisan and spoke to the owner and he was out here within a couple days and sealed my system and fixed my issue without replacing my unit. He even went a step further and made some recommended upgrades that cost very little to help save money and keep my house cooler. If you are considering a HVAC company I highly recommend them . Very happy long lasting customer here. And when my old unit does go out I know exactly who I will be calling. read less - 7/18/2018

Eric came out to give the estimate. He provided a host of options and made recommendations that best suited the job. He knows his stuff and is willing to spend as much time as necessary to answer questions. Follow up emails were promptly returned with straight forward answers and professional opinion.Alekos, the owner, did the installation himself. He is a friendly, personable young man. The work was completed pretty much in a day with a return visit for the city inspection. His price was very reasonable.
