Fast, courteous, knowledgeable service. Highly recommended. If you are seeking an HVAC professional for Nest installations (even for an older home), I highly recommend GreenLeaf Mechanical Services. Went above and beyond to assist with an issue with my furnace that turned out to be a $1 fuse.
These guys are the place to go for a mini split ductless installation in the Chicago area. I called many places but this company knew exactly what I was asking for and they took great care of me when they installed my mini-split ac system. A+
