I am going to knock R&K down 1/2 star from my original review.  I know I can't give a 4.5 but that's what I want to do.  While they were great, I found out that they advertise on the radio for at least one services that no one needs.  Keep in mind though that the guy who came to our house did not pitch any service with a low ROI.\n\nAs a reminder the top 3 ROI projects for saving money on energy, from several experts I talked to who wanted to be off the record, were:\n\n1.  Seal vents\n2.  Insulate\n3.  Window shading\n\n[Now, this isn't in the top 3 but if you have an electric water heater then adding a timer will save you money.  Get an electrician (shop around) and the whole thing can be done for under $200.  Who needs to spend money heating water at 2am?  Not me.  That saved us money as well.]\n\nOur electric bill went down after R&K insulated.  Good deal.
