"They came out quickly and got the job done. The drawbacks were that the person who assessed the situation was different from the two workmen who came to install the new garbage disposal, and that neither of the workmen spoke English. I had no opportunity to ask whether the existing disposal could be fixed (it was relatively new) or if it absolutely had to be replaced. For a $700 total cost, I would like to have been sure. Having said that, everything works as it should and my sink is working again."

"I called avila plumbing and heating services and they were able to come out the same day and give us an estimate on replacing our old water main line. They did an amazing job and I would definitely recommend Cayetano and his guys."

"I have hired this company three times ..(1) laundry room renovation, (2) removing a microwave and installing an over the stove ventilation fan hood (3) a home water filtration system. Let me expand on this.. I had a filtration system installed end of last year, it started leaking and the original plumber pretty much ignored me and my phone calls. I called Alvco for help. They promptly responded. Upon inspection of the system, I found out it had been installed incorrectly â ¦ Tim completely reconfigured it â ¦ copper pipes, shut off valves, bypass shut off valves and pressure release valves â ¦ not to mention replacing the leaky filter encasing. Every job they have done has been done way above my expectationsâ ¦ I will , honestly, never use anyone else, They are knowledgeable, efficient, prompt, friendly, great communicators and they listen . This company is second generation family owned since 1984. This shows love, respect, dedication, motivation and just overall family tradition, In my opinion, these are all very positiveâ ¦ running a business, or just living each day. Deb"

"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."
