We have hired Darrell Ing twice to do work on our church's solar hot water system. The first time was about five years ago. Not remembering which firm had worked on the system earlier, I tried to schedule work with the original installer who never bothered to send someone out even after several phone calls. But, when I called Darrell Ing, he listened carefully to the problem, made a site visit within the day, proposed a solution that was the most cost effective, and scheduled a repair within the week. They found more that was wrong when the job was underway, but managed to replace all defective parts within the day. The cost of the work was reasonable. The only hiccup for us was getting payment for the extra work. Darrell asks for payment upon completion of the work. Our church pays through a third-party vendor. I had to ask the office manager to come in on her day off to cut a paper check, and then I had to ask the Treasurer to make a trip into town to sign the check. This took coordination and cooperation.

Darrell Ing of Hawaiian Energy Systems Inc was super helpful. He did not try to sell me something I didn't need and installed a standard water heater based on the size of our household. Work was done in a timely manner and Darrell and his crew were professional and efficient. I plan to use them again.

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.
