Solar Water Heater System Repair
Quick response to our inquiry. The tech arrived on time; he was friendly, efficient and knowledgeable. He disconnected and sealed off the roof-mounted solar tanks to stop the leak. We are now scheduled to have the tanks removed from the roof.

"Thank you for your feedback. It was a pleasure working with you! Please keep us in mind if you (or any of your family, friends or neighbors) need any solar support (pool, hot water, PV, ESS)."

My experience with CleanTech Home Energy was by far the best from researching to vetting to installation including interviewing previous customers.very neat and clean installation . We had our system installed in September of 2022 and activated in October of 22. CleanTech had no shortage of satisfied customers to speak with during the vetting process which ran contrary to one of the larger and older companies who advertise heavily on television during the time I was taking bids. They could only provide me with one reference! Astounding for a company that’s been in business for more than 80 years. I heartily recommend CleanTech Home Energy Solutions.

Plain and simple, it was a very good decision to hire Clean Tech. The technician, Pablo was amazing. Also, Karen was very helpful and answered all my questions. Iâ ve had three estimates before I went to Clean Tech which beat the competition by a mile.

I had been struggling for months to get my solar hot water system functioning properly, and spent a lot of money in the process. In total frustration, i looked for another company to fix the problem. Clean Tech responded immediately to my telephone message and had a technician out the same day. Issues others had not been able to resolve were fixed in 20 minutes! The system has been operating efficiently since their service.

CleanTech guided us through a complicated water heater problem - where both the manufacturer and the installer wanted to avoid resolving the issue. We thought our recently installed and badly leaking water heater had to be replaced, but Pablo from CleanTech fixed both manufactureing and installation problems saving us thousands of dollars. Karin from CleanTech watched over us and always had a plan b or c - a very comforting situation.

Workers came prepared with gloves and face masks. Very knowledgeable and quick workers. Fixed both solar and hot water heaters and pressure reducing valve. Pablo even went on roof to inspect my panels and noted missing flashing over roof penetration, assisting me to visually inspect the issue. Would highly recommend.
