A comprehensive home energy evaluation is the crucial first step toward a cost-efficient, comfortable, and healthier living environment. By leveraging state-of-the-art, advanced technology, our team can accurately pinpoint primary energy waste areas in your home, providing the most budget-friendly solutions to ensure maximum comfort, lower energy expenses, and improved indoor air quality for a safer, healthier home.

Our technique in conducting in-depth home energy assessments focuses on a thorough, all-encompassing examination of your home, which sets our "holistic whole-house energy evaluation" apart from basic "clipboard audits" offered by many utility companies and service providers that provide discounted audits to promote their products or services.

Our holistic whole-house energy evaluation meticulously inspects the building envelope (encompassing all components that constitute your home's exterior structure, including windows, doors, insulation levels, and air leakage between construction materials); all combustion devices like furnaces and water heaters; and the airflow within the home to guarantee that the air you and your family breathe is pure, healthy, and secure. During the assessment, we utilize infrared cameras to detect air leaks and insufficient insulation, blower doors to measure air infiltration levels in the home, and duct tests to confirm the proper sealing of your ducts, among other advanced tools.

Reach out to us with any questions or to discover more about our cutting-edge home energy evaluation process; we're eager to discuss it with you and help optimize your home's energy efficiency.

     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,...

    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...
