How to cover a bulky AC unit without blocking airflow
Covering or disguising a bulky AC unit restricts airflow and ruins cooling efficiency, even when using slatted covers. Enclosures also block the frequent access needed to pull units out for cleaning, leak repairs, and replacement, while hidden piping alternatives require lowering ceiling heights. This prevents residents from hiding unsightly equipment without risking unit damage or losing living space.

“Condo association rules won’t let me get a different kind of unit so I’m stuck with these units in every room that takes up floor space. Is there any kind of special cover or way to disguise it without interrupting air flow for the unit”source ↗
“No. You will mess up the efficiency or possibly damage the unit. The Friedrichs we use crap out all the time anyway.”source ↗
“I did this. It sucks. Even with slats the airflow still sucks. Wouldn’t recommend.”source ↗
“We also have to pull them pretty frequently for cleaning, leaks, replacement.”source ↗
“The technician we spoke with says we will need to have an additional 15cm (half ft) cavity under the ceiling to run all the piping, this would lower the ceiling height in the hallway and living/dining which we prefer not to do.”source ↗
“In the photo attached to this post it shows how our vents will be (pumping air horizontally), however it isn’t clear whether we need that secondary panel that sucks air up.”source ↗
“Is there a supplier of more aesthetically pleasing grates?”source ↗
