100w Sub panel
William T.

I was looking for an electrician to install an EV charger to our home. Steven was very helpful throughout the whole process. He was able to stop by and take a look at the main sub panel and found that it was full. He suggested some options of adding an additional sub panel and install the charger. He was very knowledgeable and gave us a great deal. He took only a few hours to put everything toegther and did a great job. We will definitely consider him for future electrical work.

The lines from the condenser on the side of the house to 2 of the three bedrooms and zones.

We had 2 mini-split systems installed in our house 10 days ago. It's SO WONDERFUL to not only have A/C, but also to be able to control the temperature in each room. DUALTECH SOLUTIONS far-exceeded my already-high expectations, and were a true pleasure to work with. I had done my research and gotten a lot of really high quotes, and Steven Song came out assessed what our needs would be for our 3 bedrooms (One 3-zone system) and a separate high btu system for our "open concept" large area. TCL units were an excellent choice; they're very quiet and energy-efficient. [quite a contrast from the 7 box fans we had going 24/7 and we were still miserable.] Steven's price was so reasonable and about half of what all these other HVAC companies had said. He and his crew of two others are experts in what they each do and are perfectionists. Also, they were very considerate of our furniture, using covers and cleaning up after themselves at every turn. I can't say enough good things about these guys. We'll be using them again to install a mini-split system in our rental unit for our tenants. [This heat has been beastly and continuous this summer, and we are so delighted to have 70 to 72-degree temperatures in the house. We're happy. Our cats, who had been miserable along with us, are happy now too. It's the best decision we've made in quite some time!]

We requested an outdoor outlet to be installed. Installation was clean and efficient, and they are super responsive.

I'm so grateful to have found Chris through yelp. We hired him to help us restore power to a…read moredoorbell so that we could hardwire a new one. While it sounds simple, it was a hard task to find the transformer since it's not ever located in a standard place. We ended up not finding it to no fault of his. Throughout the process he talked through his thoughts and really demonstrated his master electrician knowledge and problem solving capabilities. We settled on installing a new transformer in our garage that would be easy to get to and be the least amount of damage to run the wires. Chris was a pleasure to work with. Pricing was fair. He is honest, reliable, great communicator, and very respectful of your home. Being Asian, no shoes in the house is important to me and he was so kind to take his shoe booties on and off depending on where he was working. That is hard to come by with many contractors and I very much appreciated it. I'd absolutely call him for any future jobs!

I recently hired Caldera Power Services to wire the heater for my sauna, and I couldn't be happier…read morewith the experience. Chris was incredibly responsive from the start, answered all my questions quickly, and provided the best rates by far after I contacted at least five other electricians in my area. He and his apprentice were able to run a dedicated line from our subpanel in the garage right outside to the sauna. They also installed the heater and temperature sensor (this is highly recommended by the heater companies! Don't install these without professional help!) The work was completed professionally, efficiently, and with great attention to detail. It took them a few hours but they finished it the same day. It's hard to find contractors who are both reliable and fairly priced, but Caldera Power Services delivered on both. I highly recommend Chris and his team to anyone looking for quality electrical work. Definitely will be hiring him again for all my electrical needs!

This review is about 9 years overdue. When my husband and I moved into our first house, we had…read moreNshan and his crew come fix some minor issues such as an arcing breaker, change switches, and install Nest cams and outdoor lights. He did such great work we didn't talk to him again for... like 9 years lol. I recently contacted him again to do an electrical inspection after the home inspector found a couple of small issues in a home we purchased, and we wanted to make sure there weren't bigger hidden ones. He took a look, reassured us it wasn't anything major, and said the halogen lights across the whole house were overloading the breaker. We are in the process of having him switch all lighting in the house + install exterior lighting and have no worries nor regrets. Wound up having East West switch all like 150 lights in the house, install exterior lighting, change switches to Lutrons, install outlets for hidden wiring and home network setup, so much work and everything was done amazingly. I know it's gonna get done right. Nshan is truly the most professional contractor I've ever worked with and is such a friendly and warm person. East West is the only company I've ever been like, we HAVE to find them again if we need more work, they are just that pleasant to work with. Always on time and very communicative. Can't recommend enough.

Failed Inspection, Poor Communication, and No Accountability…read more I would caution anyone considering Advanced Electrical Services based on my experience. Scheduling with this company was incredibly frustrating. Communication was poor, and I repeatedly had to follow up just to confirm whether their technician was actually coming. The bigger issue? The electrical installation failed inspection, and I was subsequently quoted an additional $1,100-$1,300 to correct the issues. This was especially concerning because their company had performed the original electrical work. When I questioned why I should have to pay more to fix something that should have been installed correctly in the first place, they claimed their original work had passed inspection approximately five years earlier. I repeatedly asked them to provide the original inspection report to substantiate that claim. Despite multiple requests, they never provided any documentation. I also tried to give them the opportunity to explain the discrepancies, clarify what had gone wrong, and work toward a reasonable resolution. Instead, they stopped responding entirely. What bothers me most isn't just the additional expense. It's the lack of accountability, transparency, and customer service when a legitimate concern was raised. My advice: Get everything in writing, request copies of permits and inspection approvals, and don't assume that work was properly inspected just because a contractor tells you it was. I gave this company multiple opportunities to resolve the situation privately before sharing my experience. Unfortunately, they chose not to respond. I would not recommend them.
