All I can say is, if you haven't done this yet, WHY NOT. Very informative. We are in process of upgrading our home and PECO is running a $25 home assessment promotion currently July 2018. The Energy Auditor for PECO In-Home Assessments gave us information and pointed out items we didn't even think about with upgrade and efficiency. So if you can spare the roughly 1 1/2 to 2 hours for the review, they walk through your entire home with you and point out items that could help you "button-up" your home. We had recently had installed a ductless air for the attic and the Energy auditor pointed out until we finish up the insulation that we started, we are basically cooling the outside and wasting energy, he recommended we simply use exhaust fans until we "button up" the insulation.
