We were impressed with Bryan's outstanding professionalism and excellent skills. We immediately noticed his sincere interest, dedication and integrity with regards to resolving any concerns that we had. He was also punctual and very neat and clean. So, it is with sincere pleasure that we would like to acknowledge and commend Bryan for providing us with the very best service. His work is impeccable and exemplary. Katie, at the office, also kept us informed every step of the way. She has impeccable business etiquette, listening skills and professional decorum. We continue to be very grateful to both Bryan and Katie for their time and assistance. You can rest assured that they are a refreshing asset to their industry.

Even 100 stars could not do the justice to what a professional, efficient and caring service that…read moreKatie and Bryan provided: 1. Katie immediately answered my first phone call, explained HERS and the entire process to me, with a super reasonable quote; 2. From the moment I decided to work with them, Katie sent me texts and emails with appointment schedule, and straight forward guidance of CalCERTS registration and reports; 3. The certified validator Bryan arrived on time, with needed equipments and tools, and was VERY POLITE and RESPECTFUL of our property. Just as much as Katie does, he cares about his customers. The HERS testing went so smoothly and professionally. Bryan explained the policy limit of inflow/outflow efficiency ratio must be less than 5%, and we passed. Bryan left passed 12pm, by 4pm the same day we received CalCERTS official report and certificate in our email from Katie. From my first confirmation with Katie, this HERS testing project was done in less than 3 business days! It could be done in 24 hours but I would not be home that time so Katie coordinated per my schedule! After 1.5 years working on a (still ongoing) house addition&renovation project and experiencing so many headaches caused from unprofessional (and/or greedy) contractors, Katie and Bryan are definitely THE BEST. If you ever need HERS testing in Bay Area, please, support honest and great people like Katie and Bryan!

Alfredo and his assistant came to my home in Willow Glen and performed a full evaluation of where the energy loss was coming from and what options I had to mitigate it. His report was thorough and I liked that he prioritized what I need to do right away and what can wait. Alfredo had a call with me to go over the results of the various tests that were run and made sure I understood every detail. Very happy I engaged them and I am looking forward to having warmer winters and lower energy bills

Fast forward to the present, the HVAC company we selected for a new heat pump and ducts uses Elem3nts to do the required HERS testing AND handle applying for the homeowner's rebates from Silicon Valley Clean Energy and TECH Clean (very convenient). The entire process was smooth - quick and painless. The Elem3nts team was on time, professional, and left the house just as it was after they were finished. They're very experienced and knowledgeable about HERS testing. Communication around scheduling was excellent, and one rebate has already been received and the other is on its way. Elem3nts has been great!

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

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.

They all charged an expedite fee to do a rush job. My architect recommended Nick, and I am SO glad we chose him. His expediting fee was more reasonable than the others, and when I explained our urgency, he jumped on our project the next day. He asked a lot of detailed questions because he places a high priority on accuracy, while at the same time using solutions that will be cost effective. He is top notch in his trade, hardworking and very honest. I felt that we got a lot more than the price he charged. I would recommend FRI Energy very highly, and if I could give Nick 10 stars, you would have seen it here! Thank you Nick!!
