"Luke and crew did an energy audit and followed up with insulating some crawl spaces. They were easy to communicate with, knowledgeable and flexible. Not high pressure. Reliable, efficient and polite. And they cleaned up after!"

"Everything went pretty well. We were especially pleased with the insulation installer. The assessment seemed a little cookie cutter. The assessor setup the blower device and wanted to be on his way ASAP after it was completed. They generated a huge report with recommendations and explanations of energy audits, energy use, potential savings, etc. I had some followup questions, the home energy auditor was not always responsive to email questions. I have more questions than most people. Generally speaking the job was done relatively well and I'm confident our home is less drafty than before."

"My objective was to fix a frozen water problem in a laundry room addition. The fellow doing the audit offered to expand the objective to include a free total energy audit with solutions to other energy improvements that might be considered in addition the main objective of solving the frozen water line in the laundry room addition. Their total energy saving audit appeared to make sense but resulted in a cost more than I could justify. However the cost to just solve the frozen pipes in the laundry room addition was not of enough dollar value and needed to be added to some of the other recommendations to justify their involvement. I can understand their need to limit their involvement in jobs of a certain dollar value. However I just need a small portion of their total recommendation and will seek someone that can justify a small job..Some of the energy saving recommendations made sense and I may consider some of those recommendations in the future."

"Larry and his team were incredible from start to finish. Larry was prompt in coming out and keeping his word, from our meeting time to the cost of the project. His team was extremely knowledgeable and thorough. His team pointed out issues that needed immediate attention and addressed them accordingly at no extra charge. I know the return on investment will be easily visible on my energy bills for years to come. I have another insulation project slated for next spring and will not even think to call anyone else. To anyone reading this, I recommend you do the same."

"Very well.  Morning Star referred me to a free energy audit as a Missouri resident which will provide a $400 credit to my utilities.  The windows installed were double pane Heartland windows.  I've seen a significant reduction in my electric bill this summer immediately.   The installers did a great job.  I will be asking for their assistance again to finish the remainder of my windows.

Energy Efficiency Auditing FAQs, answered by experts

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.
