"Navien Tankless Hot water heater was not putting out adequate hot water. Matthew Jones was able to troubleshoot the system, finding a valve with a bad o-ring. The valve was replaced and we have plenty of hot water now. Matt was very courteous, friendly and most of all a confident worker."

"If you have Noritz tankless water heaters you best speak with them. Three other shops just wanted to replace my "good" Noritz rather than repair or do some maintenance."
