HVAC reviews in Walnut Creek, California

I called Ariston H&C system for a second time because I have an apartment rental in Moraga, and my tenants have a problem again with the heating system that was installed decades ago. Alekos the technician shows up on time again, and this time it was a gas valve. He sent me a bid for the valve cost and installation as well as the installation—no pressure—for a brand-new heating and cooling system. I chose the new system installed by Ariston since I had another bid done. Ariston gave a fair price. Michael in the office arranged for scheduling and payments before and after the work was completed. No-fas-no-mas. I'm just waiting for the inspection to be done, which I think is going to pass no problem. I recommend Ariston H&C, guys!

Ariston has always provided excellent service. Through the years they have installed a heat pump and a whole house fan. Most recently they helped me find and repair a gas leak in the furnace area. I highly recommend them.

Alejandro and Aquiles did excellent work. They arrived right at the appointed time and were very courteous and conscientious. And the work was finished more quickly than we had anticipated.

We went with Ariston to change-out our old HVAC system to a Heat Pump. They did a great job, and their bid was lower than the other quality company we were considering. Highly Recommend.

I had a great experience with Ariston. They were professional, did a really thorough job, and the pricing was very fair. I was pretty specific about how I wanted things installed, and they had no problem accommodating all my requests. They also followed up with me when I reached out with questions and after the job was done. Highly recommend!

Very positive experience. Reasonable quote that was adjusted when I asked for a price update. The two workers who came out to install my new furnace were excellent. On time, courteous, knowledgeable, and did a great job in a timely manner.

Quick, to the point service by the professionals. Diagnosed and fixed my furnace issue in less than 30 minutes. Pricing is very reasonable too.

Brandon and Walter did an excellent job!

They claimed to rodent-proof my home, but within a month, I found new signs of rodents. I scheduled a follow-up; they never showed up or responded to my messages. After I posted a review, they angrily called to demand its removal, then ceased communication entirely. Avoid this shady business.

Thank you rami, we're really appreciate your kindness and professionalism working on our attic. We'll definitely going to recommend our navigator and family! Thank you so much David.

Choosing Eco Energy Bay Area for my HVAC needs was a wise decision. Their contractor was not only skilled but also respectful of my home. The system they installed runs flawlessly, and I'm enjoying consistent comfort without any issues. I highly recommend their services!

Rami and his team did a great job at helping me remove old insulation and seal entry gaps in my attic prior to installing new insulation. They started by protecting my flooring and items. They finished on time and provided great customer service. If you’re looking to replace or install insulation, I would recommend rami and eco energy.

I recently had the pleasure of working with Eco Energy Bay Area, and I couldn’t be more impressed with their professionalism and expertise. From the initial consultation to the final touches, their team demonstrated exceptional attention to detail and a strong commitment to energy-efficient solutions. They communicated clearly throughout the entire process, keeping me informed and ensuring that every aspect of the project met my expectations. The results were outstanding — the quality of work was top-notch, and everything was completed on time and within budget. I highly recommend Eco Energy Bay Area to anyone looking for reliable and eco-friendly home improvement services.

I never do reviews but I'm more than happy to do it for Eco Energy,

They are great! They insulated my non vented flat roof ceiling and I was very happy with the result.

rami is really knowledgeable and he gave me are great deal.

He sent a really professional team to work in my house. Giovanni & company team they knew what they were doing since I opened the door. They had the best attitude they are competent,efficient and experience (Really nice people).

I will recommend them to anyone who ask me about insulation!

Called Eco energy to have them remove the old blown in insulation from my attic space and install R38 rolls of insulation. Robert and his crew arrived around 9:30, put in plastic protection for the floors and sealed off the area so insulation would so insulation material was contained. They vacuumed all of the blown in stuff, sealed gaps and disinfected the attic space. They rolled in the R38, cleaned up the area and sent me pictures of the attic space throughout the process. They finished up by 4:30. The workers were quiet, efficient and very friendly and polite..

I had such a great experience with Eco energy
! I live in Oakland , CA, and my attic really needed some attention — there were signs of rodents and a lot of old insulation and debris. The team came out right on time, explained everything clearly, and got straight to work.

They did a super thorough attic cleaning and rodent control treatment, sealed all the entry points, and made sure everything was spotless before they left. Everyone was friendly, professional, and really cared about doing a good job.

Now my attic is clean, the rodents are gone, and my house even feels fresher. I’d definitely recommend Eco energy to anyone in the Bay Area who needs attic cleaning or rodent control — they really go above and beyond!

Very professional company great atmosphere..

Commenting on building- super cool! Can’t tell what’s on windows ? Drive my quickly - and had to look to see what the business was. Love the building design!

Отлично всё сделали.

My old Viking oven was on its last leg - two knobs falling off (requires thermostat replacement), one ignitor dead, the other almost there, temp sensor spent, bulb out. It wasn't a cheap repair, but I know these parts are expensive independent of any labor, and it now works perfectly. Took about 2.5 hours of constant work from the repairman.

Excellent service . Responsive and thoughtful
