Best Water Heater Troubleshooting in Dallas TX

Would never use this company. Purchased a home and had my water heater flood the kitchen and living room. The previous owners happened to leave the receipt from NTX attached to the water heater. This was installed without placing it in a precautionary overflow pan, nor did they hook it up to the drain right next to the heater! Lazy and unacceptable shortcut that highlights the absence of ownership in their work. When I contacted this plumber, I was yelled at by the owner Mai and accused of trying to get something out of my misfortune. She went further to say they would never warranty a 7yr old heater on parts or labor. Her lack of professionalism and business sense doesn't surprise me considering the work they perform.
