"Don Paz responded within 5 minutes of my request and came out at a time convenient for me to check my water heater that was not working. He explained everything very well. I had a new air conditioning & heating system installed a few days prior and the company had not turned the gas back on which was why I had no hot water. Don was very safety conscious checking with the inspector of the heating/ cooling company to make sure it was safe to turn the gas back on. He had the water heater working in no time at all and did not charge me for the visit. I also asked him about water softeners since mine no longer works and he was very knowledgeable and answered all my questions. I will be calling him to install a new softener. I was very impressed with the service. I would highly recommend!"

"I was highly impressed with the advice I received from Glenn, which I was advised to get with the home builder first to find out the specific cause of the problem with our tankless water heater, and then proceed from there to decide the action to take, if more additional work is required."

"Tankless water heater installed in June developed a leak and corroded. The heater was not installed with proper clearances per the install manual of the manufacturer. However, after bringing up these issues, they promptly moved the heater into a better location providing proper clearances and replaced the corroded parts."

"Glenn was very professional and went out of his way to please us.  The installation of the RO and water conditioner went really well.  The installers went right to work and were friendly.  Right away we noticed such a difference in the water.  It's amazing!  We couldn't be happier with what we purchased!"
