We’re electrification experts. If you want to go all-electric, let’s do it right—together.

We’ll tailor a plan for your fully electric home. Your heat pump, water heating, insulation, panel capacity, battery storage, and solar should all be planned according to your goals, timing, and budget.

Let's get electric.

How does your home and HVAC system perform?

Most California homes are leaky, improperly insulated, and have terrible HVAC systems. Your home is gaining too much heat in the summer and losing too much in the winter because it isn’t properly air-sealed or insulated. The HVAC system is oversized, with ducts that are too small and very leaky. You should expect more from your home and its HVAC system.

 Trustindex verifies that the original source of the review is Google. We had a very positive experience working with Eco Performance Builders on a significant amount of work in our home, including attic re-insulation, air sealing, bathroom fan replacements, and a kitchen vent hood installation.

We especially appreciated their building science approach. They were thorough in explaining what they recommended and why, helping us understand how the different improvements would work together. They also performed blower door tests before and after the work to verify the results, which showed a substantial reduction in air leakage.

Throughout the project, the team was friendly, punctual, and very communicative. Whenever we had questions, they responded and took the time to explain things clearly. We really appreciated their thoughtful approach and follow-through, and we would happily recommend Eco Performance Builders!

 Trustindex verifies that the original source of the review is Google. I have yet to hire Eco Performance Builders, but I wanted to write an mention the great customer service and coordination in coming out, spending over an hour, and giving us prompt quotes. In a world of no-shows, wrong days, and flakey companies, EPB stood out as a class act.

I have 1 project to solve first, but after that, I'll chose these guys. Also, Kyle gives a lot of info and confidence in working with EPB with his deep knowledge and experience.

 Trustindex verifies that the original source of the review is Google. Eco was recommended  to me and after working with them in January 2026, I, too, can recommend this local business - competent, customer services oriented and most of all, superb  teamwork end to end.

While the technology and the hardwares used are employed by many HVAC providers, the operation touches the attic to the crawl space and will take several consecutive days to complete, and the cost is not inexpensive,  so  organization, time management and customer care are critical to a desired outcome; and these are ECO's fortes.

From the initial call to the project end with a sign off from the  city inspector,  everyone including ECO's outside contractors worked with me; they thought of things that I did not even notice.

I could not have asked for a better construction/improvement outfit.   I wish all my home projects can be done in such an effective and efficient way.

 Trustindex verifies that the original source of the review is Google. I had Eco Performance Builders install a ducted heat pump, attic sealing and insulation, and a heat pump water heater at my house last year. I found the experience of working with them to be exceptionally positive.

From start to finish, every member of the team I worked with was highly professional, knowledgeable, and responsive. I always felt like I was talking to a friendly expert, not a salesperson.

They patiently answered all of my questions and worked with me to create a HVAC system that was perfectly tailored to my house. The installation work was smooth and efficient, and they were able to accommodate a few small change orders (e.g. relocation of a dryer vent) at a reasonable price. Their process for collecting rebates and incentives was very well-managed as well.

Overall, I'm very pleased with my new heat pump and water heater. My house feels comfortable year round, and it feels great to live in a fully electrified home. I'd enthusiastically recommend Eco Perfomance Builders to anyone.

 Trustindex verifies that the original source of the review is Google. We needed a new heater and went for a heat pump. Their approach is top shelf: our uninsulated house was insulated, new ductwork installed, recommended window replacement to allow for smaller system.  One month in, and it clearly was the right investment. Thoughtful design, quality work, and great crews.

 Trustindex verifies that the original source of the review is Google. I had Eco Performance Builders install two heat pump HVAC systems with new ducts, new attic insulation, and an ERV system for my house.  From start to finish, they were very prompt, knowledgeable and professional.  Their quote was reasonable for the expertise provided — all worth it for a quality job well done.

 Trustindex verifies that the original source of the review is Google. I have now completed my second project with Eco Performance Builders. The first was a heat pump water heater in 2023 and the latest just completed project was a ducted heat pump hvac system with new insulation. I am thrilled with them both. The water heater was a challenging installation because of space limitations but they recommended a wonderful unit and with imagination and determination made it work in my space. The hvac system design was comprehensive, engineered, and perfect for my needs. The system itself is quiet and amazingly efficient. The staff was professional, considerate, good communicators and all-around nice people. It all began with Kyle who handled the initial inspection, estimates and contracts, as well as graciously answering my infinite questions, and included the stellar Alberto (crew lead on both jobs) and his truly excellent team, the insulation crew (great containment work), production manager, tech person, office specialists and more. I appreciated the big things but also the small things such as daily cleanup. While it took a good bit of time for them to get to my projects (because they are very very good, they are also very very popular), the work itself was completed on target and worth waiting for. I highly recommend Eco Performance Builders and only wish I had more projects to do with them.

"I would go a winter without heat just to have Eco Performance replace my system over another contractor. It almost doesn't feel right to compare Eco Performance with other Bay Area HVAC companies because Eco is operating at such a higher level."
