What Are the Common Reasons Your Heater Won't Kick On?

When your heater won't kick on, it can be due to various factors. Here are some common reasons that could be causing your heating system to fail:

If the filter appears dirty, replace it with a new one.
Make it a habit to change your filters monthly during the heating season to prevent future issues.
