Here is a 2600 square foot split level in Gates. His house was cold, so he had some insulation work done a few years ago. Now it's two years later, and his house is STILL COLD. Why didn't the insulation work? That's when he decided to call True Energy Solutions to solve the mystery.
Imagine going skiing while wearing a knit sweater. If air is traveling THROUGH insulation, then it's no longer INSULATING. Here's another one: Imagine leaving a window open all winter -- It doesn't matter how good your insulation is if there's a way AROUND it. We found LOTS of insulation in his attic, but none of it was doing any good because of the "ceiling penetrations" beneath it.
Seal up the holes, and you stop the problem. Simple... but almost always missed by the other guys.
Problem: Cold in Winter
Problem: Hot in Summer
