Rave Review

Thank you David and gang for the very good work that you guys did. We are now enjoying our house that we moved in over two years ago.
Ida C. | Daly City
Customer service is back in fashion and Building Efficiency delivered.
Zack B. | Berkeley
It was a pleasure working with Building Efficiency. From the informative energy audit that they performed at the beginning of the project (required and rebated as part of the PG&E rebate process) through the abatement of the old asbestos covered ducts to the installation of the new furnace / ducting system Building Efficiency was thoroughly professional and effective. We’re thrilled with the improvements to our house, and look forward to the next phase (insulation) soon.
Kent D. | San Francisco
So far, the team has been nothing but super professional! They have been prompt and clean up well after themselves.
Kalvin S. | Belmont
Great from start to finish. Patient educating us, thorough with rebate-qualification … These guys are pros, but with the small-business touch. Top quality. Definitely recommend.
Joy C.
These guys did an amazing job. They were super communicative during and after the entire process and even did some things they didn’t have to do to make my home both safe and more energy efficient. My first gas bill after the installation was already $100 less and that was just for 1/2 of the month.
