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!

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.

Very happy I engaged them and I am looking forward to having warmer winters and lower energy bills

He inspected my system then said he didn't think his test would find anything but I wanted him to do it just for peace of mind because the result would help me know next steps toward solving my issues.
