I have been in the heating/cooling industry for many years, as many of the respondants obviously have (installers brainwashed by their Janijunk Sales Reps) Re-read what everyone is saying! Same parts? Poor installers? Both are true. These units have "some" same parts, but they are the cheapest versions Goodman can buy. Now, they distribute their product in such a way as anyone can buy it "over the counter" with no credentials or required training. There is a lot to know about sizing, airflow, etc to make these work correctly and last a long time. They are usually required to pay cash and are very small companies. No business sense! Cheap price! You will "definately" get the poorest quality installations when you use this product! Bottom Line. Grin & Bear it you Janijunk installers that are red faced right now!
