$79 for Home Performance Evaluation ($300 Value)

An energy consultant visits the home for 2-3 hours, using thermal imaging to detect cold spots, along with a blower door test —which changes the home's interior air pressure, pulling air in through leaky spots and making them easier to detect. Each session ends with consultants drawing up a plan for home modifications that will reduce energy bills and unwanted drafts.

Go Green Energy Consulting

Go Green Energy Consultant’s team of environmentally conscious experts can reduce home energy bills by 20-30% by uncovering the insulation insufficiencies and leaky spots that welcome drafts indoors. Their process begins with trawling Michigan houses with thermal cameras and industrial-strength fans, uncovering the cold zones that suggest air leakage or closets full of icebergs. After pinpointing these draft sources during “energy audits,” the team can alleviate them with a custom combination of remedies such as caulk, foam, and sealant. The resulting snugger environment requires less energy to heat, rendering obsolete band-aid solutions such as overheating to counteract drafts.
