    Franklin Whole Home Batteries

    Cinnamon Energy Systems delivers a truly premium solar installation experience, marked by professionalism, organization, and comprehensive service. From the outset, the process was seamless, thanks in large part to the outstanding support provided by my representative, Jessica. Her deep knowledge of solar systems, paired with her responsiveness and attention to detail, made the journey toward energy independence clear and stress-free. What sets Cinnamon Energy apart is their ability to manage every aspect of the project under one roof. They have established teams of roofers, electricians, engineers, finishing specialists, and logistics coordinators--all working in concert to ensure a smooth and timely installation. This level of coordination reflects a well-honed system backed by experience and a commitment to excellence. One of the most significant advantages was never having to worry about utility company coordination, particularly with PG&E, or navigating city permits and inspections. Cinnamon handled it all. They also made tax season simple by keeping all invoices and documentation in order, ready when needed. Every touchpoint, from initial consultation to system activation, reflected high standards of service and communication. I always felt informed, supported, and confident that the work was being done right. (Writing supported by Chat GPT, but formulated from my sincere experience.

    We went with Cinnamon for a 12 panel system with Enphase micro inverters and two 5P batteries, and are very happy with the system and the support we've received from the company. They distinguish themselves from other solar installation companies by providing dependable follow through, reliable communication throughout the design and installation process, directly employing all workers, quality of installation, and by being a truly local company (based in Los Gatos). I highly recommend them to anyone considering solar in the Bay Area. The salesperson was professional, knowledgeable and helped us work through the options for our system. Of course, the sales people for ALL the solar companies are going to be super helpful because they want your business. One thing that Cinnamon did better than other companies during the sales cycle was to not pester us to death with calls and emails. Other companies continued to call repeatedly even after I informed them we had already signed on with Cinnamon. So irritating... Our Cinnamon rep stayed in touch but avoided being annoying. Also, unlike some other companies, Cinnamon didn't use any high-pressure tactics ("If you don't sign up by the end of this week, blah blah.") Where I believe Cinnamon really sets itself apart is how the company executes after the sale. If you've ever had a contractor that you had to keep calling, or who set expectations and then didn't follow through, you know how frustrating that can be. With Cinnamon, the communication and follow through was nearly spotless. There was one incident where the person coming out for our pre-design inspection was late and didn't call to inform us. But other than that, the company did everything they said they would do when they said they would do it (or earlier). Whenever we had questions, someone always responded promptly. They guided us through the permit process, inspection process, and getting our PG&E plan changed. At every stage of the project, our expectations were set and then met or exceeded. I am also very happy with the quality of the installation. The crew scheduled two days for the installation, but completed the job in one. The quality of the work appears to be very good. Everything was done to plan and all the components are laid out very neatly. Note that in the photos, Cinnamon offered to paint the conduit to match the house but we declined. One tip: if you don't want conduit visible on your roof, make sure that is part of the initial design (before you sign the contract) so the contractor can estimate the extra labor to hide the conduit as part of their work. Our house has old wiring, so we did experience problems with a few breakers tripping. It happened twice. This created some inconvenience because the problem occurred at night. For example, one breaker would trip immediately after we started our microwave oven. So that night, we had to heat our dinner in the oven. Inconvenient, but not the end of the world. But the electrician was able to resolve each incident the next day. Overall, the crew was professional and took pride in their work. And as I mentioned previously, everyone is a Cinnamon employee. I'm not saying all subcontractors are bad; I'm sure many do excellent work. But for us, having subcontractors in the mix introduces possible quality and reliability concerns, so we liked that all the work was done "in house." Since the installation, the system has been running reliably and we are delighted with it. I enjoy using the Enphase app to monitor the energy production and storage. I especially like the micro inverters so that I can see how much energy is produced by each panel, and because if one of the micro inverters fails, the remaining panels will continue to function. Again, we are very glad what we went with Cinnamon. I don't think we got the lowest price, but their price was competitive. We chose Cinnamon because we value supporting a local company and also enjoy the peace of mind that comes with knowing they do (and stand by) all their own work.

    An ideal winter day with strong solar production.

    I had a really strong experience working with North Breeze on a full HVAC replacement and zoning…read moresetup, and what stood out most was how different their approach was from other companies we spoke with. Several competitors leaned heavily on sales-driven recommendations and were quick to dismiss questions or concerns. North Breeze was the opposite. They approached the project from an engineering perspective -- thinking through system design, airflow, zoning behavior, and real-world use instead of just quoting equipment. That made a huge difference in both the decisions we made and the final result. Their communication throughout the process was excellent. They were responsive, clear, and willing to engage thoughtfully with detailed questions, even when we were trying to understand more nuanced behavior of the system. I never felt brushed off or pressured into a quick decision. After installation, we had a specific question about how one of the zones was behaving. Rather than dismissing it, they came out, spent several hours diagnosing the system, and made adjustments to ensure it was working as intended. That level of follow-through and willingness to dig into the details really stood out. Four months later, the system is now working well, and we feel confident in both the install and the support behind it. If you're looking for a team that treats HVAC as a system to be designed and tuned -- not just sold -- North Breeze is a great choice.

We had no idea when it was last serviced or if it had ever been serviced at all. Henry gave us a very fair and competitive price for a tune up. Upon Henry's arrival, he was friendly and professional. He opened the furnace and showed us the burner. He explained it was in great condition considering the age of the unit and it didn't need servicing; although, he did clean up around a few areas around the burner. The blower motor was slightly wobbly, and once again, he explained it was still in good shape considering its age. He proceeded to the back patio where the condenser was located. He noted the unit was very old and that particular Freon is no longer available for servicing; however, he stated the unit did not need to be replaced just yet as long as it's blowing cold. Henry indicated despite our units being way past their anticipated life expectancy, they were clean and blowing hot & cold just fine. Therefore, no servicing was recommended and he did not charge us anything. We are impressed not only by Henry's friendliness and professionalism, but also by his transparency and integrity. Many other companies would have hopped on the opportunity to upsell the service or even sway us to replace our system right away, but Henry gave us peace of mind to give us time and to save up for an inevitable replacement in the future with Therma Tech. Thank you so much, Henry! We will definitely contact you again in the future and recommend you to all our family, friends and coworkers.

Called the MFG and saw their list of experts. Decided to call a few for a quote and connected with ThermaTech. They were very responsive and easy to set up, confirmed that they know to work around the specific model. Miguel text when he was on his way, showed up right on time and was equipped and wore shoe covers. Professional - talked me thru what he was going to do and was ant to make changes and asked me to confirm the airflow was good. Was very patient and let me check all the air vents multiple times - a very thorough job. Paid right when he left and at a very reasonable price.

Michael Calvey thoroughly explained all of the options for our house's specific HVAC needs and was very patient with me as I asked a variety of questions. In fact, he made numerous trips to our house to answer the constant flow of questions my wife and I had. Bottom line, we built a solid working relationship with Michael and this gave us the comfort we needed to move forward with our HVAC investment. Calvey Heating and Air's estimate for a new heat pump and furnace at our house was very competitive. I was amazed at how much the pricing varied from vendor to vendor. Michael and the Calvey team made the entire process seamless from start to finish. Michael recommended an electrician who did a great job with our electric panel upgrade and the permit team did a fantastic job working with the city for all of the required paperwork. When it came time for the installation, the lead installer, Servando, and his team took pride in their work for the two day install. Similar to Michael, they were patient with me and answered all my questions during the install. Following the install, the Home Energy Rating System (HERS) Team promptly arrived and conducted the necessary testing. Lastly, the permit team met with the city building inspector to successfully get the city sign off on all of the work. Throughout the entire process, Calvey Heating and Air did a great job choreographing and managing all aspects of the installation. I was constantly kept informed and Michael and his team visited our house daily during the installation to ensure all was moving forward properly. Lastly, a final walk-through was conducted by Johnny from Calvey ensuring that the install was 100% perfect. Once my wife and I have had time to work with and get familiar with our new system, Michael indicated he will have his team come by our house and balance out our vents if needed and answer any additional questions we may have. Overall, my wife and I cannot be happier with our decision to have Calvey Heating and Air install our new system. Their service was great from start to finish and there were no hiccups. We highly recommend them. Thank you Michael Calvey!

Michael came out to my house and walked me through the pros and cons of a heat pump HVAC. For my home, the extra money made no sense. I really do not need central AC. We then talked about a new Carrier, high-efficency furnace. That was exactly what I needed. I also opted for the Ecobee Smart, wi-fi enabled thermostat. I am extremely happy with everything. The price was right. The installation was flawless. The post-intall QA walkghrough, by Johnny, went really well. ThenI worked with the folks that checked all the boxes post-intalleation. HERS test was easy with a pass.. Today, we passed the inspection, in under 5 minute. Every person I dealt with was amiable and professiona. The office staff always very nice. Michael Calvey was a joy to talk to. Thank you to Johnny, the project manager, and the folks from HOPSTER that facilitated the post-installation test and inspectioin. From start to finish I met with Michael on February 12th. The 16th the new furnace was intalled. February 17th Johnny did the QA walkthrough. February 18th HOPSTER did their pre-test and inspection walkthrough. The HERS test was done February 23rd. March 5th the city inspection was complete. I will continue to use Calvey for annual maintenance
