Eco Performance Builders

Eco Performance Builders are The Best in HVAC and energy improvements. Customer service is top notch. We are extremely pleased with choosing them and would hire them again for any service they provide without question or comparison shopping. This company is beyond any other hvac company out there in terms of application of the latest in heating, cooling, insulation and energy efficiency. An independent inspector told me they are the best in the industry and inspecting their work is a formality. I asked a number of other hvac companies about my duct work, air sealing, a/c options and insulation. Almost all of them just wanted to replace my existing a/c or heater, most without even looking at my ducts or insulation, never mind alternative options. EPB performed air sealing, replacement of existing traditional heating cooling system to a highly efficient ducted mini split system (no this is not with large room cassettes) performed air sealing, installed a heat recovery ventilation system

We have been doing a big remodel on a fixer-upper in south Berkeley and we feel really lucky to have found EPB. Kyle, who was in charge of our project, was extremely knowledgeable, patient, and competent. Bill, the on-site point person, was also a pleasure to work with. Clear communication, high quality work, fair prices. They also did all of the paperwork for the energy evaluation and PGE Home Upgrade rebates, which came through even slightly higher than estimated. The work they did for us: tankless water heater, air sealing, attic insulation, floor insulation, cathedral ceiling insulation, and some wall insulation. Highly recommended!

Amazing experience with Keith and Erik. We're in a newer home with a fujitsu AC that just stopped working. None of the codes made any sense and none of the simple trouble shooting tricks gave results that made sense. Our AC and it's troubles were a mystery. Keith and Erik worked tirelessly to find the issue. Their customer support, good humor and product knowledge was simply the best. If we could give them 10 stars we would. I would recommend them to anyone, even my elderly parents. Eco Performance Builders are the best!
