Sunwork have been around for a long time. They are an excellent choice for property owners who are not in a rush. They work with you on the design and installation phase, and their estimates are accurate. I had both my base system installed in 2018 and an addition installed this year. I was highly pleased with the results in both instances. They are thorough, very competent and reasonably priced.

SunWork installed solar panels for me a few years ago, and a heat pump water heater last year (2025). In both cases I've been very happy with the quality of work, communication, and price. The HPWH actually cost less after incentives than a gas WH did twenty years ago. They explain options, limitations, and the process well, and do thorough work. The only minor negatives- 1. they've been busy (especially with federal incentives ending) so it took a month or two between signing a contract and the

Reuben and his team did a great job installing our HPWH. He helped us find incentives available and assisted with the application process. I highly recommend SunWork.

SunWork did the HPWH for us. The project leader, Reuben, is very knowledgeable and professional. The whole process of converting the gas water heater to HP water heater was very smoothly. With their help of applying rebates the actual cost to us is very attractive. Since we have solar panel already, the HPWH uses less fossil fuel and also saves us a lot of money too. I'll highly recommend SunWork for your HPWH installation.

Reuben did a very good job in installing our heatpump/electric water heater. After installation, there was a leaking problem. We notified him. He visited couple of times to fix it but finally replaced the water heater. He is committed to doing sincere and honest work. I would highly recommend him.

We just finished the installation of a Heat Pump Water Heater (HPWH) in our home. We started the process in August of last year, trying to work with the company that Palo Alto partners with for HPWH installations. Their quote was higher than I expected even after applying all the rebates. I friend suggested we contact SunWork. Our situation was somewhat complicated in that we needed to bring electrical power from the circuit breaker on one side of the house to the garage where the HPWH was to b

Key attributes of Sunwork: 1) Transparent, Fair and Accurate Pricing upfront. 2) The only installer who subtracts rebates from their charges and deals with the various authorities to get the rebates. 4) Excellent Quality installation. I got heat pump water heater installed in May with the help of Sunworks and the overall experience was amazing from start to finish. The entire installation was completed in less than a day and as you can see from the photo its a clean install. It took us less t
