Q: What size water heater do I need?
If installing a traditional water heater, the size will depend on how many people are in your home and how much water they use per day to shower, wash dishes, clean clothes, etc. This article includes a table to show you roughly what size hot water tank correlates with your family size.
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?
