"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Air conditioning in one zone stopped working over very hot weekend. Called three companies to get a quote on possibly replacing both zones before I spent money on repairing a 17+ year old unit.
Diamond was the first company with availability. Before they came over to give a quote, Bob called to ask me a few questions about the nature of the problem. He speculated over the phone of what the problem might be and what the cost of fixing it would be.
He arrived for the appointment at the appointed time and proceeded immediately to fix the unit while talking to me about an estimate to replace both zones (2 systems). He spent extra time hunting down an electrical connection issue in the unit and when done, checked out the flow readings of the system.
$258 dollars fixed the problem. Since I had scheduled him for a quote, he offered to remove the new part that he had just installed or I could leave it in and if I decided to buy a new system, they would credit the repair of this unit back against it. I elected to have him leave the fix in place.
Bob quoted me an exceptionally good price per unit for a quality Lennox system. In fact a competitor who came the following day said that he wanted to see a copy of a written quote because Diamond's price was too good.
Although I've decided for the time being to not replace both systems, I would select Diamond Heating and Air in a second!

His services were very much appreciated and very professional. Lee"

"A pleasant experience from start to finish. The quoting process was a good two-way discussion, and cordial - no pushy salesman telling you how bad Company X or Y was. Just honest, factual, and straightforward. They quoted us a system with the panels, racking, and inverter which we wanted, not what they were pushing. The quote wasn't the best (hence the 'B' for price) but it did offer the best VALUE when we considered the equipment specification and the stability of the company - an important consideration when looking at a system with a 25 year life! The installation was scheduled by our coordinator, Sherry, and the team showed up when promised and got the job completed on time. Quality of workmanship was first rate and the entire installation was done with care, and tidied away before the team left. Permitting and PG&E inspection were all handled by Sherry, and that was also quick and flawless. Overall, the system they installed easily meets their projections in terms of performance, and it effectively pays for itself. We really couldn't be more pleased with NRG Clean Power and have recommended them to friends and neighbors. We'd recommend you give them your consideration if your looking for solar power."

"Matt has done various extra jobs for me that pertain to maintaining my pool. A pump replacement that was required resulted in a reduction in my electric bill....just as he said it would. Also, I had a light out in the pool that three other companies said they could not fix. Some tried and could not fix it because they couldn't get the wiring out due to too many "U" turns in the wiring. Matt said he could fix it and I had my doubts. He came and had it fixed and working in about 1 hour!
