Frequently Asked Questions
How do I know what filtration system I need?
It depends on your water source and what contaminants you are dealing with. City water typically needs carbon filtration for taste and odor. Well water may need sediment, iron, or sulfur treatment. A.J. LeBlanc Heating will assess your situation and recommend the right system.
What is the difference between a sediment filter and a carbon filter?
A sediment filter physically removes particles like sand, silt, and rust. A carbon filter uses activated carbon to adsorb chlorine, chloramines, and organic compounds that affect taste and odor. Many whole-house systems use both in sequence.
How often do filter cartridges need to be replaced?
Replacement frequency depends on your water quality and usage. Sediment filters typically last 3 to 6 months. Carbon filters last 6 to 12 months. We can set you up with a maintenance schedule.
Will a whole-house filter reduce my water pressure?
A properly sized filter should have minimal impact on pressure. We size the system to your home's flow rate so you will not notice a difference in your daily water use.
