Question for HVAC folks. How much efficiency, if any, is lost by wrapping the outdoor A/C unit with 1/2" filter material?
Any reference material or website to quantify?

What would be the reason to wrap the outside unit in filter material. I know dirt on the condenser can affect the cooling of the unit. It seems to me, reducing the airflow might have the same effect? http://www.pitzersonehour.com/.../why-do-i-need-to-clean.../
