Services were good, prices were reasonable. That said, after a few months of seeing insulation drop through a vent i climbed into the attic to find some of the duct blowing into the attic and not connected to the vent (I love spending $$ on cooling my attic....keeping it comfortable for the roof rats). That said they were very responsive. I had it done in the winter so once we hit 115 in July i may bump or drop them another star :).
