"I called Roadrunner and they sent a technician out the same day. He identified the problem and gave me an estimate for the regulator repair and having a new water shutoff valve installed. I felt the cost of the regulator was high and he suggested that I could purchase the part myslef and only pay for installation charges. The part would not receive Roadrunners guarantee, however. I decided to locate and buy the needed parts and called Roadrunner for guidance. They were very helpful in guiding me to the correct parts. I called once I purchased the parts and they came out and installed them the next day. The technician was very professional and friendly. He completed the job in about 1.5 hours and cleaned up thoroughly afterwards. A month later, and everything is performing normally."

"After a frustrating year where multiple plumbers (including that big TV advertiser) had failed to troubleshoot our freezing radiant heating, we were at a loss. Luckily, we tried one more plumber and landed on Alex Ortiz who was able to determine the problem and repair it. The system now works great and gas bill has even gone down. In addition, he spotted a few other items done incorrectly and resolved those. Alex is a skilled plumber, professional and honest."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."
