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.

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.

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.

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.

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.

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.

We had a wonderful experience working with Eco Performance Builders. Their team including Kyle, Nick, David, Miroslav, and Paul did such an excellent and thorough job. They are so professional and kind. They truly went above and beyond to make me and my family comfortable during the installation process. And our home feels so comfortable now because of their great work. Thank you so much Eco Performance Builders!

Eco Performance Builders recently installed a mini-split heat pump system in our home and insulated our attic spaces. From the initial estimate walk-through to the final day of the job, their team was professional, courteous, and thorough. Every employee we worked with was top-notch—knowledgeable, respectful, and clearly committed to quality work. Don’t be discouraged by the lead time—this is a long-term investment that pays off in comfort, energy efficiency, and home value. We also found them to be competitively priced. We’re extremely happy with the results and highly recommend Eco Performance Builders to anyone considering a home energy upgrade.

About Eco Performance Builders
Eco Performance Builders counts 16 years of retrofit work around the Bay Area, with the Oakland EcoBlock among the larger projects it points to. The shop works out of Walnut Creek in Contra Costa County. It also takes jobs in Lafayette, Orinda and Danville, and reaches into Alameda County.
Heat pump retrofits out of Walnut Creek
Utility gas heats 60% of housing units in Walnut Creek, per the American Community Survey (2024). The median home there was built in 1974, per the same survey.
The company says its licensed crews design and install the work themselves. Jobs run from single-family retrofits to multi-family electrification for property owners and HOAs. Eco Performance Builders dates the start of its installing to 2008.
Ducted systems, mini-splits and envelope work
The services it names are heat pump HVAC, whole-home electrification, attic and wall insulation, air sealing, water heating and indoor air quality. On the equipment side, the company offers ducted heat pumps, hydronic air handlers, ductless mini-splits and radiant systems. It also explains when a ducted system fits better than a mini-split.
The company ties this to testing. Eco Performance Builders describes the founder's shift in view after measuring the performance and air quality of homes he had built. In its duct work, the filter goes in at the return grille, which keeps particulates out of the return duct and makes filter changes easy.
Reviewers most often describe heat pump installs paired with new ducts and attic insulation, and they credit the crews with patient explanations and careful design work. Several mention permitting through to the city sign-off. A few advise that lead times are long and the cost is real.
The office keeps weekday hours, Monday through Friday from 8:00 am to 4:30 pm, and closes on weekends.
The company says it holds Energy Star Home Performance certification and HEEHRA rebate certification, and it names Green Point Rated Contractor of the Year and Energy Upgrade California Contractor of the Year among its awards.
NOAA normals for 1991-2020 put Walnut Creek's mean temperature at 60.4°F, with an average high of 71.4°F and an average low of 49.4°F.
