Review by in Cedar Rapids, IA
Everyone at Energy Nerds were amazingly helpful. We got in touch with Mike and he came over to check things out as soon as he could. He was very patient and did a great job explaining their products and which ones would work best in our house. Mike was always available by phone when we had additional questions. He even came by the day we got our attic insulated and to check in with us! They got everything finished up quickly and quietly and made extra sure we were happy with the job. We can t recommend Energy Nerds enough! My family already plans on contacting them again in the future to add a solar fan and possibly some panels.

Review by in Waterloo, IA
I appreciated being contacted almost immediately after initially giving interest in a quote for blown-in attic insulation. It wasn't long before Mike met with me to discuss the project. I got lots of information on insulation and other products recommended for attic venting, etc. Mike is one of the nicest guys around, and is passionate and knowledgeable about what he does, and is not at all "pushy". I feel he cares about customers as if they are friends. Was able to schedule the work within days of his being given the "go ahead." Glad to have had this work done by Energy Nerds, and hope to work with them again. Highly recommended!

It is hard to assess them fully as my system has not been in long enough to fully understand the effectiveness.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
