Review by in Alamo, CA
Very quick to respond knowledgeable , scheduled quickly , got the job done quickly , efficiently . The team was very polite and clean and let me know what they were doing at all times. Cleaned up a big problem left by other contractors. Did all my duct work and it works great.

I was charged $1300 for the work that provided but when I asked for a detailed invoice he declined to give me one. The original invoice that was provided had a general description of the cost and it said the work was not guaranteed. When I turned on the Air Conditioner it did not work. $1300 and no air conditioner. What a waste of money.
Response by 411 Heating & AC, LLC: Hello, You put a review on YELP which is almost the opposite of this, Please read your YELP review it states my heater broke. Your first issue was a broken AC, I gave you a price you agreed and it was fixed, then you paid me and was happy.. You called again for your heater not working in the morning and wanted it fixed for free because we fixed your AC, almost a month before. You and your neighbor started yelling, I told you I am recording you and your neighbor because you guys got so out of line. I shared your recording with the security and the manager security which they apologized on your behalf. I wrote a 3 page complaint for your security and they have the report. The first YELP review is your the second you had your neighbor put one for me which was negative.

Mr. Opeyani was able to figure out in 10 minutes why my system didn't ever work properly, something no one else did in 32 years. Very nice company to work with. There when they said they would be, worked quickly and seemed to really want to do things to my satisfaction. I wanted a couple of things done differently and they did so quickly. They took care of the permits. I definitely recommend the company. I'm very glad I hired them.

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.
