Their communication with me was excellent, and everyone I interacted with was extremely professional and very skilled in their respective tasks. Big thanks (!) to Joran, Sergio, Gene, David, and the other crew members whose names I didn't get. TY! I feel very comfortable recommending SDI's work - they did what they said they would do, and they did it quickly and professionally! Their estimate was competitively priced; it was neither the cheapest nor the priciest., but all things considered, SDI seemed to offer the best value for our money. I'm also very pleased with the results of the insulation! We had R15 fiberglass blown into our exterior walls, and even after just one night I can tell the house is much quieter. Today's outside temp has been in the mid-50's, which is chilly for early May, so I'm able to write this review with oddly good timing: new insulation works, lol! I'm now very eager to see what it does in the summer heat, which was our main reason for having it blown in. All in all, I am very pleased with the SDI did on our home and feel quite comfortable recommending their services to other homeowners.

Chris came out to my house twice due to a rather unusual set up of my electrical panels.

I am looking forward to my full audit report and using the TED 5000 to get a handle on why my bills have been so high. I had looked around quite a bit before callling Power Down, and I would recommend Chris to anyone in the same situation. Eric

We went through the online energy audit in Mountain View and because we were in our house less than a year we were led to PowerDown for an in-house audit.

He also showed me how to work the thermostats correctly to switch over to the backup old gas furnace if needed. Thanks guys!

They planned the system out well and came to adjust things accordingly in the months post install to ensure it was running perfectly. Recently, prior to selling my father in law's house in Oakland, they installed a vapor barrier that was suggested by an inspector. We needed it done in a timely manner due to the sale timeline and they were responsive, professional and reasonably priced plus they did a fabulous job. Thank you for your service!

We had an outstanding experience with Eric and his team. In the last year, we used Eric to create…read morea plan to completely electrify our house (getting off of gas), and then managed the work over several phases (making sure we were happy with one phase before hiring him for the next phase). In total, he managed installation of 2 heat pumps to replace our old HVAC system, induction cooktop to replace gas stove, heat pump water heater to replace gas water heater, as well as all the electrical work (new panel). They also managed all the city permits for us, and made sure we got all the credits (checks just kept showing up from various rebate programs which was really nice to offset some of the costs!). Eric is very knowledge and seems mission driven to help people go green, not just trying to make a buck. They offered us a range of options, even discouraged us from some more expensive ideas that we were considering. Eric also had some design suggestions for the HVAC contractor which ended up being brilliant and significantly improved the temperature balance across our house - something that many previous HVAC folks had never managed to fix for us. So we ended greener but also more comfortable too as a bonus! Last thing I'd say is that they have been very responsive even after the job was done and we had paid them. When our water heater started acting up about a year after the install, Eric showed up early the next morning on a holiday weekend to debug the problem and quickly fix it. So thankful for that!

I just finished my first project with emeraldECO--covert from a gas to nearly all electric home…read more Every aspect of this project has been excellent. The initial consultation, needs assessment and design went smoothly. It's clear that Eric, Diane and Tony are experts in what they do. The demo and installation phase went incredibly smoothly and was on time. The installers are all excellent at their jobs, from the technical side to clear and professional communications. The project wrapped up with a walk through a few weeks after completion to make sure everything worked well, which I appreciated. Most importantly, I went from a house that had lots of spots with no cooling to my new HVAC system now cooking the entire 1,600sf house equally and quietly. And the price was clear, fair, with no added costs later in the project. I look forward to my next project with emeraldECO - install solar and battery!

From the very start of my engagement with Attic Bros it has been fantastic! I found them in a…read moresearch on Yelp and no joke, my 8 year old calls me Bro, so figured I would fit right in with the Attic Bros! I think within maybe 20 minutes of submitting my Yelp quote I had a call back and an appointment. Michael came out and did a THOROUGH inspection of the attic took a ton of before pics. But not only that he then sat down with me and went through the entire process, which is quite frankly, amazing. He also answered all of my questions and offered some input on my ducts. He made himself available for any other questions too, which was so nice since my husband wasn't around - there's always another question. With this process, not only do you get your old attic crud sucked out, they look for and seal any entry point for critters. They add mesh from the inside plus they go around the whole perimeter from the outside of the house too just to make sure they caught all entry points. They seal all air gaps from things like recessed lights and fans. And then they sanitize. Something about knowing my 70 year old house got a deep clean is VERY satisfying for my OCD cleaning tendencies. The insulation went in - they use a batting that is 12" thick, my attic before probably had an inch, maybe 2 in spots of the old blow-in stuff which was just dust and dirt and disgusting. This batting is eco-friendly - no pink artificial coloring, just the insulation which also is no longer harmful. Night one and I already saw a difference. Usually when it gets cold at night by 2:00 am our home temp inside drops, we stayed a steady temperature throughout the night, I might be a bit crazy, but it feels like there's a sound dampening effect too - I don't have to have the TV on as high of a volume. Follow-up, they add traps and will come back to monitor in a couple weeks to make sure there is no activity. Another over the top customer service layer - we had Jordan as our project/site manager for the day - I was texted by the system with his picture, LOVE this feature, its really helpful. And he called when he was closer. He kept me updated throughout the day and was just really kind, very professional and the crew he brought, Jesse and I did not catch the other gentleman's name - they worked so incredibly hard, and efficiently. We really appreciated this crew, they were amazing. If you are hesitating for any reason to get your insulation in your attic done - DON'T - it is 100000000% worth every dollar, which by the way is an incredible value when you really think about what it does for your home. I am quite mad at myself for not doing it sooner, but certain things had to happen first, so here we are! I would choose Attic Bros in a heartbeat and whole heartedly recommend them!
