Fantastic experience working with emeraldECO. They installed a highly efficient heat pump to provide central air conditioning and heat, a highly efficient heat pump water heater, wiring to convert my gas cooktop to induction electric and a new sub panel.

I received three bids and I went with emerarldECO since they managed everything (including the many rebates). I didn’t have to deal with managing any contractors/sub-contractors. Diane and Eric are fantastic to work with!! I am a very picky person and they exceeded my expectations.

The project was a huge success. My utility bill dropped significantly, I now have central AC, the new induction cooktop is far better than gas (great heat control and easy to clean) and no more gas pollution.

We were thinking about getting a new heat pump for our house prior to Covid, but decided against it at the time. Boy I am glad we did, because we discovered emeraldECO. The work was simply outstanding, and the support for rebate navigation was incredible. Don't hesitate to get your system install scheduled. You won't regret it. By the way, we actually got more done for less money, even before the rebates, when compared to pre-Covid bids.

Emerald Eco installed a heat pump water heater at our home. They did a fantastic job covering all aspects of electrical work that was needed, the local permitting and the installation itself. Diane is very knowledgeable about incentives, rebates and tax credits and maximized these for our installation, lowering our net cost. I like them so much that we’re starting a new project this year to install a HP HVAC system! I couldn’t recommend them more enthusiastically.

emeraldECO cared for all my needs relating to getting a HPWH. They kept me informed about all details and they knew and understood all about Rebates. I did receive my rebates because emerald ECO helped me with the application process. EmeraldECO helped me through the process of getting a permit for installing the HPWH in my garage. The city of Sunnyvale has special requirements in this regard and we were able to satisfy them. When I am ready to change out my gas furnace, I will work with emeraldECO for my HVAC.

We had a great experience with the emerald eco team. They went above and beyond to accommodate a tight schedule to install our electric water heater. The communication was great, the team was professional, and the quality of work was very good. They delivered exactly what we wanted.

At some point in the fall of 2023, we realized that our gas-powered water heater had been on borrowed time for about 10 years. We became aware of a company called emeraldEco and quickly came across various testimonials that led us to pull the trigger on an electric water heater. emeraldECO is a small family-owned business run by an engaging couple committed to a greener future and to helping us all take whatever little step we can in reversing climate trends. They talk the talk because they've walked the walk. Diane and Eric are very knowledgeable, do full electric installations on new homes, and are happy to retrofit older homes on individual devices. We loved that they understood our situation and didn't try to talk us into changes we couldn't afford at the moment, such as going all-electric, but provided the same above-par service as if we were building a new home.

A huge bonus for us was that emeraldECO applies for all necessary city permits, and any and all rebates that are applicable at that time in your part of the SF Bay Area.

The two teams of electricians + plumbers were very timely, engaging, hard-working people, careful about any indoor space they had to walk into (everyone wears shoe covers) and highly skilled at connecting with our existing systems (in our retrofitting scenario).

We highly recommend emeraldECO and stand by for any question.

I am so happy we found emeraldECO and worked with Diane and Eric to do multiple projects at our home this year. They helped us from beginning to end to complete upgrades to our electrical panel, install an electric vehicle charger, replace our gas water heater with a heat pump water heater, designed and installed our rooftop solar and battery backup system. They were always organized, communicated very well, and partnered with us to share information about all the technology considerations during the design process. Additionally, they handled all the paperwork for permits and rebates and everyone who worked at our home was considerate, on time and cleaned up. We plan to work with emeraldECO on one last electrification project and have also recommended them to several neighbors!
