Improve Your Home's Energy Efficiency by Identifying Hidden Air Leaks
Many homeowners believe that windows and doors are the primary culprits for heating and cooling issues in their homes. However, hidden air leaks from cracks, chases, and penetrations can contribute significantly, equivalent to one or two open windows.
Air leaks can cause a variety of problems in your home, with some houses losing 30% to 50% of their heat due to these leaks. Identifying and addressing these issues can vastly improve your home's energy efficiency.
At Home Star Iowa, we utilize cutting-edge diagnostic technology to detect and document hidden air leaks in your home, going beyond a mere visual assessment. Our comprehensive report details our findings and provides tailored recommendations for both low-cost adjustments and larger upgrades to enhance your home's energy efficiency.

Blower Door Testing for Airflow Analysis

Our blower door testing service allows us to measure airflow and determine the heat or cooling loss in your home. We can pinpoint specific problem areas and identify where air sealing would be most effective, as well as when your home requires additional mechanical ventilation.

Carbon Monoxide Testing for Safety

Carbon monoxide, even in small amounts, can lead to severe health problems. Our trained professionals at Home Star Iowa can assess the safety and efficiency of your combustion equipment, including appliances, water heaters, gas ranges, space heaters, furnaces, and boilers.

Leak Detection with Thermal Imaging

Our team at Home Star Iowa employs thermal imaging technology to uncover air leaks and insulation vulnerabilities hidden behind your home's walls. Additionally, we conduct a static pressure test to detect installation issues or obstructions within your air ducts, as air lost during transit from your HVAC system to your living space can be substantial.

     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...

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...
