What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
Tech quoted $780 to clear one AC drain line; when customer declined, tech claimed his drive was too far to honor the $75 diagnostic fee and increased it on the spot
“The technician quickly identified which interior drain line was causing the issue and then told us the price would be $780 to clear the blockage. That is an astronomical amount for a straightforward task. The technician told us that he had driven a long distance and that the diagnostic fee was not worth his time so he changed the price.”
Red flag
Yelp reviewer alleges tech pushed unnecessary whole-house filter ($1,100) and pressure regulator ($900) — county confirmed normal 80 PSI pressure

Late-arrival pattern: Yelp reviewer scheduled noon-4, tech arrived at 5:45; another reviewer booked 8 AM, tech arrived at 11 AM with no proactive update
Cited in 2 of the 100 reviews we analyzed.

The evidence — in reviewers' own words
Critical
“Was quoted over $7,000 to replace and clear lines. Brought in Cambliss Plumbing that is also local and did everything in less than 2 hours and was told it cold take 2days buy Chris. No longer getting any business from us. New unit in place with 7 yr warranty and told only ask 2yrs.”
“While doing other work, they knocked off a sensor for my A/C drip pan and quoted me ~$300 to replace, why not just re-install the thing you just broke? Another time, when going up and down my stairs and attic, they tracked in mud all over the carpet (they wore shoe covers but then just kept the shoe cover on while walking outside in the rain/mud) and dented my walls in at least 5 spots with equipment. I asked about, …”
“I called Roadrunner Plumbing because I had a leak in my shower faucet that was getting worse and worse. They said they could get someone out same day which was great. I scheduled my appointment for between 12-4. At 3:45 I called the company to make sure someone was still coming and at this point Tabitha told me the tech was running late and would be there a little after 5. The tech Frank arrived around 5:45. He …”
Positive
“Mike Genson and crew were polite, professional, and thorough in maintaining our plumbing. We have been long time clients of Roadrunner Plumbing, always excellent and expert services rendered with each visit. We recommend their services to all!”
“Had a wonderful experience with this company. They responded quickly and were very efficient. When the tech had to come back out they worked quickly and came out when it was convenient for me. Mike was very kind along with his assistant that came along with him. Overall I would highly recommend.”
