"If I can give this plumbing company zero stars I would. I had a slab leak, and this company came out for leak detection. I was told that I have two leaks and they cut two lines. They were charging almost 65000 for rerouting two lines. My insurance company also brought their own plumbers and did their leak detection and they found only one leak. The adjuster called RT Olson a fraud company and he almost declined my claim. The insurance refused to fix the two cut lines. They only covered one line and I had to pay for the other line out of pocket. I asked RT Olson to fix the other line that he cut and was not leaking but he refuse to take responsibility. Then he send me an invoice for the leak detection and threatens me to take it to collection and add extra fees. This company is a fraud."

"All the people sent to my home were professional, friendly and efficient. Eric, the repair tech, had to give me the bad news that my furnace was not repairable. He listened to my requirements and desires for the replacement and gave me a solution that matched at a reasonable cost. Novlin and Brandon came the next day to install the unit. They were careful of my home and floors. They installed the new furnace quickly and efficiently. They cleaned up after themselves very well. Before leaving, they showed me pictures of the work in the areas that I couldn't easily get to like the attic and roof. I'm very happy with the whole project"

"Benjamin and his entire crew were the best! From the start I was provided with personal, thorough and professional inspection of my HVAC unit. When I decided that I wanted to do an entire replacement of my system, Benjamin provided multiple options to fit my needs. He always responded to my questions and their crew showed up on time each day they were scheduled to work. My project was tough as I live in an older townhome, but Benjamin and his team worked hard to make sure everything was done right. He truly cares about his clients, and the quality of work that he does. If you need any type of work done on your AC or HVAC unit - this is your guy! "

The tech was courteous, professional, explained everything and made sure everything was working properly before he left. "
