TJ was a great technician. He identified the problem(s) quickly and according to his report to me all is working properly now. I was very grateful for his visit. Thank you KSB for your quick response. I failed to do a review I believe for the hot water heater installed on March 11, 2021. I was also very pleased with the installation of the heater. Sorry I have forgotten names, but I believe one was Jimmy. Both guys were very nice and did good work in my opinion. Looking forward to KSB continuing with Fall and Spring Check Ups of my Heating and A/C Service.
