Energy Nerds

Excellent work! We first worked with Matt in Cedar Rapids to get an estimate and he showed us his recommendations for the work. Dalton and Mike did the installation. Great at keeping us informed of the work progress and after work cleanup. Professional and considerate of our property. We highly recommend!

Overall, they successfully put insulation in my attic, so they might be worth a call to get an estimate. Based on my experience, if I have future insulation work, I will probably get an estimate from them, but I won't give Energy Nerds preference if any other place is comparable. For reference, my work was to add insulation to my attic. Cost: They were within about $100 of the other place that I called, so they were at least competitive. When I priced out the insulation cost from the local hardware store, the price from Energy Nerds was about 2x - 3x the cost of the insulation. After the federal insulation rebates and accounting for my time, it looked like it was still worth it to have have a contractor do it. Service: Matt was super-nice when I called to ask why he wasn't at the appointment when I might have had the day wrong, and was willing to answer all of the questions I had regarding the insulation installation. The installers managed to show up an hour after their two hour arrival window. Otherwise, they seem friendly enough and knowledgeable about their job. When I went in the attic to verify the work, it looked like they got the appropriate amount of insulation in there. I can't see the ventilation to confirm if that was correct, though. Other notes: Unfortunately, when they went to install the insulation, they found that my soffits were block with insulation and gave an estimate to clear the insulation from the perimeter of my attic. I can accept that unexpected things may happen, so I went forward with it, even though the cost was about +15% of the original cost after the federal insulation rebate. After I accepted the updated estimate, I found out a couple of things: - They only put the vents in between every other pair of rafters, so they would have to clear only half the perimeter, which made their basis of estimate that they put on the updated bill about 50% off. - The installer didn't even remove the portion that blocked the soffits from the attic and dispose of it - they just moved it out of the way. I can accept that I agreed to pay the extra amount, but they itemized removing a certain amount of insulation on the bill, which as far as I can tell, was not work that they completely performed. I feel like they might have misrepresented that portion of the work, which is why I would prefer another company if I have any other insulation work don in the future.

Daniel Garvey in Omaha was awesome, one of the most upbeat and positive people I've met in a while. He explained everything thoroughly and clearly, along with photos and visual representation and made it a no brainer decision to use Energy Nerds. I now know how important it is to have proper attic insulation and environmental conditions. The install team was excellent, professional and very friendly. I couldn't believe what an instant difference it made to have proper insulation and ventilation in our attic. If you are considering having this type of work done, I highly recommend Energy Nerds!

Joel did a good job explaining to me how much insulation I needed and how installing an attic fan would help. The team arrived and blew the insulation and installed the attic fans as promised. They promptly notified me in advance about schedule changes. Edit 2/23 - my Feb utility usage has dropped from 2200 kWh down to 1600 kWh relative to last Feb, considering the number of dangerously cold temps weve had in Feb. Highly recommend.
