Air Conditioner Won't Turn On - The Basics
I know that some of your are moonlighting as HVAC technicians, but this is even for you do-it-yourselfers...when an air conditioner won't turn on, you'll need to understand some key HVAC terms before we can explain how to troubleshoot it. Otherwise, how the hell will you know what we are talking about?
Key Terms to Know When Your AC Won't Turn On
When your AC won't turn on, we will need to check a few things ourselves before we call in the professionals. But how can I tell you to check your "condensing unit," for instance, if you don't even know what that is?
Split AC Unit - A split unit is an air conditioner that has two parts: one inside (in a closet, attic, or utility room inside of your house), and an outside unit.
Packaged AC Unit - A packaged unit is just one big unit that has both of these parts, and is typically located on the roof.
Condensing Unit - A condensing unit (or "condenser") is the boxy-looking part of a split AC unit that is outside.
