The pricing also seemed extremely reasonable. We ended up doing insulation in our ceilings, such a seamless experience and they supported with the rebate process, had finances not been a limitation we would've done walls. Highly recommend, in fact writing this review has inspired me to loop back with them about their suggestion that our furnace is waaaaay overdue.

A very positive experience! We just has SDI insulate the exterior walls of our 1960's-era Belmont…read morehills home, and I was very impressed with the work they did. 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 from Power Down was great. I originally got his name from another home energy auditing…read morecompany. They did not do the type of electrical auditing that Chris does. Chris came out to my house twice due to a rather unusual set up of my electrical panels. I initially thought I might be able to set up the TED 5000 to monitor my electrical consumption, but good thing I got him to do it, cause it turned out to be more complicated than I could have figured out. 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. Chris from PowerDown came out, found where the energy hogs were and made recommendations. We replaced a number of ceiling flood lights and followed his other advice and dropped our bill $50 in one month from $205 to $155, a 24% reduction! He even came back and helped swap out some of our outlets and is incredibly responsive to any additional questions. I highly recommend this service.

Highly recommend!

I…read morehope they agree to fix the other problems soon in the following order including but not limited to: 1. Clear HVAC permit with the City by providing them the 24 HERS test report. 2. Replace the radiant barrier by removing the existing one completely and replacing with a true double-sided foil all across the attic and not just the patch work of fixing by reattaching and covering other open areas. 3. Remove the remainder of the old ducts from the crawl space 4. Diagnose and fix the thermostat issue. I will update the post as soon as these issues are taken care of.

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!

This is a long-overdue review: in the winter of 2023, emeraldECO installed a heat pump water heater…read morein my garage (replacing a 10-year-old gas heater) and upgraded the electrical supply in my kitchen to be ready for the induction range I hope to install someday soon. The project went in two stages: one day, the electrical crew arrived and took care of the kitchen, and also replaced the shoddy job on the electrical subpanel done by the rooftop solar vendor the year before. The second stage was the arrival of the plumbing crew, who came to remove and dispose of the old water heater and install the new one. In both cases, the crews were highly professional, amiable, and careful about leaving my home clean. The price for their work was reasonable--especially if one considers that they made a convincing argument that I didn't need to upgrade my electrical panel, saving me thousands of dollars. And, as promised, the impact on my electrical bill has been negligible, while my gas usage has been reduced to pennies per day.

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!
