My home warranty sent us to Fosters to repair our pool heater. The technician showed up; looked at the outside of it and drew the conclusion that the heat exchanger was leaking. He then called the home warranty company and told them the heater was leaking due to lack of owner maintenance. The warranty company then refused to fix it. I called Fosters to complain. They said they were willing to repair it for $1900. That is $400 more than a new one   This company is unethical and an absolute rip off.
