Question Fixed poor vent airflow by blocking pipe at bottom of my AC unit, is this bad?

I'll preface this by saying I am not at all experienced with maintaining any kind of HVAC hardware outside of replacing filters.

Earlier tonight the pressure coming out of my room vents was non existent. I checked the filter, gave it a quick clean, and there was still no airflow. I found a small pipe coming out of the bottom of the unit, it looked like it had been taped over before, and had busted. All the airflow was coming out of there, and the refrigerant pipe was one big icicle.

I went ahead and covered that pipe back up and airflow is back throughout my home. However, I am curious if this is a safe way to fix whatever is happening with the seemingly random duct at the bottom of this unit. The only branding I found on that part of the unit is All-Style. If it's important at all, the furnace is a Dependable Ninety-Two.

Welcome to the forums.

There shouldn't be anything open to let air out.
Can you post a picture of what you have there....... How-to-insert-pictures.

Did you tape over the condensate drain? That's the only pipe I can think of the comes out of an air handler.

You say the refrigerant pipe was iced up. That’s your problem and why your low on airflow. Your evaporator is frozen. Did you thaw it?

"Your evaporator is frozen."

^^^^^ Turn the system off and let the evaporator thaw out. Sounds like you have a refrigerant leak - not something you can fix yourself.

Hi, if it is the condensate drain pipe you taped, remove the tape before you turn the unit off to defrost, if thatís whatís required.
