Home Energy Audits


A home energy audit is the first step to a more comfortable and efficient home.  We take a whole-house approach when conducting energy audits, using state-of-the art tools to identify areas where your home is wasting energy.  Through a diagnostic blower door test, we'll evaluate how air tight your home is and determine where and how severe the leaks are.  Then, with thermal camera imaging, we'll pinpoint the problem areas of air leakage and moisture infiltration.  We'll then recommend cost-effective solutions for conserving energy in your home.  Homeowners in Decatur and Central Illinois are shocked at how much energy they can save by making a few simple improvements in their home.

Installation of Energy-Saving Products

We work with a wide variety of energy-saving products to give homeowners in Illinois exactly the energy efficient solutions they need. We’ll even work with your local utility company to install low-cost, energy-saving products as they are made available. For walls, attics, basements, and crawl spaces, we remove old insulation and install new, energy-efficient insulation for greater home comfort. We’ll install spray foam, blown-in cellulose, blown-in fiberglass, or traditional fiberglass batts according to your needs. For areas that have air leaks, we offer air sealing services for a more airtight home. The energy-saving products we install in your home will offer year-round benefits and help you save up to 30% on home heating and cooling costs.
