The Definition of Excellence

  I can't believe I haven't published my review! Alekos is great! He's replaced four furnaces in our apartment building and did such a great job we had him do the entire hvac system for the remodel of our home! Needed a tankless water heater, well, he can do that too. For reliable service at a competitive price you cannot go wrong with this company!

  I really enjoyed meeting Eric, he responded quickly to my Yelp quote request and came back with a proposal that was much more reasonable than others.  He was great to work with and replaced a condensation pump and look forward to working with them again.

  Excellent job.  They arrived 5 minutes early, handled the problem and articulated what i should do to maintain the system very well.  Also had a friendly attitude.  Highly recommend.

  The team was super friendly and helpful, diagnosing the problem, fixing on the spot, and gave reasonable estimates for recommended future work. Minus one star as I've tried now getting back in touch with them for several days to complete follow up work and have received no response.

  I am a GC, electrical, and solar contractor, and these guys are #1!  We have used them on our projects a bunch of times.  From small troubleshooting to full system replacements, they are absolute perfection!  Quality equipment, quality installations, and top notch customer service!  Small 900sf full systems, to custom high end Eichler projects, they have been consistently a pleasure to work with.

  AMAZING! Meticulous work and honest business!! Alekos will take care of you! He and Lee did an amazing job overhauling our homes entire original 1970's heating and AC system. This company takes pride in there work and you can tell happy customers genuinely make Alekos happy!!! Once that AC kicked on I looked at him and said, "I think you might have just saved my marriage!!!" Support local small businesses and go with these guys!

  I can't say enough good things about this company. 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.

  Sad to be the one breaking the 5-star streak here, but my experience of Ariston really could not be worse, and warrants a review.  Basically they held me up for a month citing stock issues, and when they finally came in for installation, they "discovered" additional duct work and attempted to up the price by another 6k! When I told them to pack and leave, they did so, but left the basement doors wide open, which I discovered 24 hours later, at which point rats already made themselves comfortable in my basement ducts.  Thank you Ariston!

Here's the full story:  They came to my house for a site visit, looked at my HVAC and panel, and followed up with a quote.  So far so good.  They told me my heating unit would need to be rotated sideways to fit the coil, but that would be no problem.  The quote was neither too high nor too low, middle of the pack.  Given the good reviews, I decided to go with Ariston.  

When installation day approached however, I received a call informing me that the AC unit that was advertised to me was out of stock.  I was given the option to wait 2 weeks, when it would come back in stock, or go with a more expensive model.  I opted to wait.  This already cost me 1 more heatwave without AC.  However, the unit did not come into stock for another month (+2 more heat waves of 100+ F).  

On the day of installation, the crew showed up and proceeded to look at my HVAC system.  Shortly after, a member informed me that "most of your ducts are metal", so they would need to be redone, which would cost another 6 thousand $.  I thanked them for wasting my entire summer and said goodbye.

  Alekos was very quick in responding to my request for a quote (maybe 10 minutes?). was at the house within two hours, put a workaround in place to get the furnace running, and was back the following morning with the new part for the permanent fix. All in all very prompt, friendly, complete and reasonably prices service. Next time i need HVAC service these are the guys I call. highly recommended.

  Ariston was way above and beyond what I expected from a customer service level. Eric was incredibly helpful. On time, friendly, reponsive, and professional. If I could add stars, I would. Fantastic job!

  Great job. My a/c went out during the 105 plus degree heat this summer.Ariston Heating and Cooling made time for me asap and were here on time and worked fast.

Gave me such a good deal on the a/c unit that I ended upgrading the heater as well.

  Alekos and his team replaced our furnace, A.C., and HVAC ducting throughout the house, and have been by several times since to make tweaks to heat ratios, clean filtration, and follow-up on little issues that have arisen. They weren't our cheapest option, but we went with them based on their sterling reviews.  Very pleased with their responsiveness, professionalism, and absence of haggling on follow-up services.

  It was a Saturday and heater was broken. I called and they were prompt, professional and took care of my problems without having to replace my furnace.

Highly recommended and very reasonably priced.

  I got referred to Artisan from a friend that had a new system installed recently.  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.

  Ariston recently replaced the vintage 1960 furnace in our duplex.  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.
Highly recommend.

  I can't say enough wonderful things about Alekos, Michael and Lee.  I had two companies "fix" my air conditioning issues.  Basically they charged a lot of money and did nothing.  I was at the point where I was just going to accept that I was never going to have a working air conditioning system.  I decided to try one last time and boy am I glad I did contact Ariston.  They are the best.  I now have air conditioning!!  I just wish I had called them first and sooner.  Don't call anyone else!

  Couldn't be happier with Alekos (the owner), his brother Michael, and the entire company!  They installed our new AC unit quickly, professionally and for a reasonable price. I would recommend their services to anyone with HVAC needs!  An extra thanks to Alekos who showed up each morning with a smile and laugh even on the hottest days of the year. These guys are good people.

  Alekos and his team member Michael came out to diagnose some clanging we experienced with our relatively new American Standard A/C unit. They were friendly and professional and explained our system and what maintenance it required to keep it in top shape.

Ariston is a top operation, they responded promptly and professionally to our inquiry and we highly recommend them for any of your HVAC needs.

  I did my research - had 3 vendors come to estimate the cost of installing mini split A/C units in my house.  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!!

  Ariston Heating and Cooling installed for us a new ductless heating  and cooling system. We highly recommend them, their price was very reasonable, they were very professional, punctual and finished their work on scheduled time. All we can really say is that they are the best heating  and cooling company around.
Eric went over board to accommodate us with all our needs considering that everything was on a last min call.
