"I called and they were here working 48 hours to install and haul away a tankless water heater. They did finishing work and completed it to my high standards. They communicated very well as I was uneducated in this area. I highly recommend them."

"Premier Plumbing Solutions installed a new Bradford White water heater at my home. Alberto did a fantastic job. He was on time and explained the process to me before work was started. He removed the old water heater. Then vacuumed and removed all cobwebs and dust from the water heater space and a couple of feet away from that area, so the new water heater could be installed in a clean environment. The install went quickly. When finished, all the work, looks professional, clean and modern to today’s standards. He cleaned up any debris and mess made during the install. Alberto did an amazing job. I definitely recommend him and his company!!"

"I don't know enough to compare (dollarwise) the tankless water heater I purchased to others in the market. I can say it's an impressive piece of equipment and is providing my desired level of service. I now have hot water throughout my home in seconds! AND, Dave impressed me immediately as a sound, honest, energetic business man and technician. In no time he and Carl were at my house doing the work I desperately needed. It was dark when they finished but they lived up to their word in fixing my hot water problem "today"!"

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Jeff was prompt with the initial quote via Yelp. He asked questions to find out more about the type of water heater I had. He sent a text message about 20 minutes early to let me know he was on his way. Once here, he had his mask and gloves on. He was able to assess the situation and within 45 minutes was able to complete the job. He also made recommendations on what to expect based on the age of the water heater and did recommend looking into getting another one soon. The payment was easy and affordable."
