Their fix was needed but not the actual source of the problem

Response from Company:

Hello, The issue reported was your thermostat and you wanted us to fix it. We did fix the issues and your system worked. You agreed for us to come out, I would really like to know what your question is so I can fix it. You left a half comment with no reason of understanding. The ratings helps us to stay on top of our company, if you have other intentions we can not help you? 411 heating & AC

1)Know that contractor's are only allowed to collect 10% in advance of the work performed not 50% by CA law. 2)Always get 3 bids (which includes ALL details like make and model of heater to be installed and cost) from different company's. 3) Make sure to lookup the companys license on the state of California website. The company doing work must have the right license- if they are allowed to have workers with their license great. If not make sure the people in your home are licensed subcontractors! 4)I had to rip out the machine installed by this company that stopped working 3 days after install. Save yourself the HUGE hassle I have to now deal with. 5)I found a company that installed amazing equipment, obtained permits etc. Yes the bid was a bit higher but we'll worth the additional money- the machine works effeciently, queitly and because they pulled a permit all of my boot jacks (where the heat comes out) were sealed making the system about 15% more effecient.

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.
