Wow! Comfenergy came to our house to conduct an energy assessment, and it far exceeded our expectations. With a special tool, Justin basically x-rayed our walls and was able to clearly show where we were losing energy in our home. He was able to determine that the builder had left some insulation out of one of our walls when the house was built, which ultimately contributed to our temperature control problems. He then gave us a three-tiered approach to correcting our situation. We highly recommend Comfenergy to solve insulation and energy loss problems. You have to see it to believe it!
