An advanced home energy audit is the first step on the path toward a more comfortable, more affordable, healthier home. Using a variety of high-tech, state-of-the-art tools, we're able to identify the key areas where your home is wasting energy and recommend the most cost-effective improvements for maximum comfort, minimum energy bills, and optimal indoor air quality and building health and safety.

Our approach in conducting advanced home energy audits is to take a comprehensive, whole-house assessment of the home, which distinguishes our "advanced whole-house energy audit" from the "clipboard audits" offered by many utilities and companies that offer a discounted audit as a means to sell products or services.

Our advanced whole-house energy audit looks at the building envelope (which includes all the components that make up your home's outer shell, including windows, doors, insulation levels, and the level of air leakage in between building materials); all combustion equipment including furnaces and water heaters; and the movement of air within the home to ensure that the air you and your family are breathing is fresh, healthy and safe. During the audit, we use an infrared camera to identify air leakage and deficient insulation, a blower door to measure the rate of air infiltration in the home, and a duct test to determine whether your ducts are well-sealed, among other tools.

     It was recommended that I upgrade my HVAC to GEO by a heating company. I had Rob come in and check my house, he is very professional and knolagable. He ran a complete series of tests, showed me with thermo pictures and real numbers how I could insulate better, upgrade my HVAC without going to the expense of GEO and save more money. Well worth it.

    An energy audit can be a pleasant and informative experience. It  was such during the one completed by Rob Novak for my house recently. In addition to many helpful suggestions to seal warm air leaks in all areas of the house, he found a problem with carbon monoxide in one place. The water heater chimney was blocked. There was a squirrel which had died inside the chimney,...

  • Thomas House
    The main thing we took away from the energy assessment was the confidence that comes with having guidelines for laying out a course of action. We knew we had issues with the home's envelope but weren't certain where to start. Using a combination of basic and complex technologies, Rob was patient and professional. He identified problem areas and possible solutions and presented...

    We were extremely impressed with the energy audit that Home Star Iowa did on our home a few months ago. The knowledge he had in regards to the energy saving tips he provided was top notch. The equipment and the detail that went into the energy audit was amazing - he explained the results of the audit in detail and provided us a report that was easy to understand, not to mention all the recommendations that will save us money. If you are wanting an energy audit done on your home - there is no...

     As the owner of a 100 year old home, I sometimes wonder where I should start in making my home more comfortable.  Rob came in and went through all of my utility bills, measured every window, checked the efficiency of my boiler and hot water heater, did a blower door test and walked through the house with an infrared camera and showed me where I need insulation, where the air infiltration is coming from.  A day later, he gave me a very comprehensive report that showed me the steps I can take...
