Q: What does a water softener do? Do I need one in my Mentor home?
A water softener can provide many benefits including cleaner drinking water and reduced soap scum buildup around your fixtures. Read this article to learn more about how water softeners work.
Q: Why are some rooms in my house colder than others? Could it be a problem with the furnace?
