"Gabriel Nieto of GN Plumbing did a fine job. He was able to visually detect a leak where the line from the propane tank enters the house, and pressure tested the gas line from the propane tank to the house to confirm the leak. With the help of his assistant, he repaired the line (replacing worn out portions of the line) within a couple of hours, confirmed there were no other leaks in the line (via additional pressure testing), and re-lit the gas furnace and water heater. Only complaint is the extreme expense ($890)."

"Aleman Plumbing contacted me right away for an appointment to look at my water heater. Their quote was advantageous compared the the other I received and they were able to schedule the work immediately. My water heater was in a difficult location and I also needed to replace a pressure control valve but Carlos got it all done very well and was great to work with."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."
