    1.5 Denver, CO

    While Roberto did show up on time...His first quote for replacing the air induction motor was over $700. We finally agreed on $500. I looked the part up...cost between $70 - $150....so he made $350 - $400 to install it. Guess i should have gone to plumbing school.

    I had an amazing experience. Roberto came to look at my furnace which broke during a cold spell here in Denver. First, A-OK got someone out to me really fast even though they were definitely busy. He gave me really good advice regarding the furnace and also took a lot of time talking to me about other aspects of my home that need maintenance. Roberto went out of his way to help me find the right furnace to replace my broken one. That exact model turned out to be out of stock, so Roberto hooked me up with a better model for no extra charge that has saved me $20-30 per month because it is more efficient. Great people who go the extra mile to do the job right and also educate! I totally recommend them to anyone!

    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)
