"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."

"My wife and I did a thorough search in getting the best A/C Contractor in the Sacramento area. The search included Angie?s List, Better Business Bureau, California State Contractor?s License reviews, personal recommendations from neighbors and friends. After all our searching we ended up going with Diamond Heating and Air. We signed the contract with Bob Weatherford who is also the owner of Diamond Heating & Air.
Both my wife and I were especially impressed with Bob?s thoroughness in explaining the type of system we really needed, the SEER rating of the equipment, and the best way of replacing the existing outdated heating and cooling system, inadequate insulation, and faulty duct installation. These were all good suggestions in transforming our home into a more energy efficient and comfortable environment. Also, it was pointed out that some of the existing ducts became loose and disconnected. Fiberglass insulation was blowing into one of the rooms. The outdated ducts were installed many years ago, and were poorly installed, wasting lots of energy, and the duct work was hanging too low below the floor joists.
Bob suggested that the new duct system be relocated and strapped contiguous to the floor joists which would allow us to walk underneath the house so we could better utilize the space for movement and storage. Another big task involved the installation of new attic insulation. This was a big job that required the knowledge that Bob has as being a Licensed Building Contractor.
Again, the thing I appreciated the most was Bob?s honesty and the effort he made to make things right. Bob and Elaine worked hard to qualify us for the SMUD low interest rate financing and qualify us for the rebates that SMUD and PG&E were offering. This helped us tremendously in bringing down the costs of the project. My wife and I are extremely happy that our home now has an excellent home energy assessment from SMUD and PG&E. We expect that our annual electric savings will be significant. We are very happy to recommend Diamond Heating & Air to our family and friends.

"My pump was leaking and getting worse. I had used Matt before and he did a good job. I gave him a call and he came over, checked out the pump and said I need a new one. When he told me the price, I decided to try to fix the pump myself. So after spending $375.00 on parts, the pump lasted a few more months before it seized. I called Matt and he came over on a Saturday to replace the pump. I should have listened to Matt in the first place. Now I have a super-quiet, energy efficient pool pump. They even cleaned the pool before they left. Just call Matt."
