Looking for honest water heater repair/replacement companies... had GreenStar Home Services out here today. My water heater is 12 years old. To bring it up to code and make repairs they said It would be better to get a new one. They also tested our water and showed it had. A lot of chlorine in it and recommended a water filtration system. I may watch too many Dateline and 2020 episodes but I'm skeptical of companies trying to sell me on packages. Any tips or recommendations are welcomed. Thank you!
