They serviced my heater after I had a big chain come in and tell me that I needed a completely new heater replacement. Because it would cost me thousands of dollars. I called R&R Mechanical, and they were able to provide the service for a lot less. It was less than a thousand dollars. The other company was telling me it was going to be like $3,000-$4,000. R&R Mechanical fixed it quickly, efficiently, and got my heater back up and running. They were really honest about everything.
