Our 15 year old AC finally gave up. Got 3 quotes and Legacy Home Energy was in the middle price-wise but seemed the most knowledgeable. New system runs quiet and our electric bill dropped $40/month.

Weird burning smell coming from the vents when heat kicked on. Turned out to be dust buildup on the heat strips from the AC season. They cleaned it all out. Easy fix but scary smell.
