I have an old home in Berkeley that required central heating. Said Opeyany came promptly and assessed what it would take to adequately heat my house. He had a creative solution to put a duct through a closet and to shoot air to the upstairs through a vent on the landing that no other contractor had thought of. He also proposed using a more powerful furnace than any other company and seemed to have a very thorough and expert idea of how to best meet my particular heating needs. His estimate was competitive and the work was completed in less time than predicted. I am delighted with my new system and would highly recommend this company to friends and neighbors. Said checked in with me after the installation to insure that I was satisfied and he and his crew were hard working, timely, and knowledgeable.

Crooks. Did not fix the problem told me my heater needed a new thermocoupler and it would be $595. I called someone else and they said there's nothing wrong with the heater. I paid 411 to come out and they didn't do one thing right. I should get my money. back we'll see.

Response from Company:

Hello Ms. Widdoes, on 9/10/18 I visited a many plex that you rented in Oakland. You had a direct vent wall heater installed "illegally" by your handy man near a window. You agreed to my service fee of $79.00.. You Your self called me many hours later and paid my SERVICE FEE BY PHONE, would you like to see your transaction and time of my visit. You then said that your handy man can do it now that I told you the issue. If you called some one else and said nothing was wrong, why would you call anyone in the first place if nothing was wrong. Clients like you should be ashamed of taking advantage of contractors. You were too cheep to do the work and the wall heater is illegally installed, shame on you Ms. W

Mr. Opeyany contacted me immediately and was able to come to my home within hours. He not only took care of the problem but was very helpful in other ways as well. I would definitely recommend him and will engage his services in the future if needed.

Expensive experience with a poor outcome. Once I tried to call him back to get the work he did fixed, he never emailed or called back

Response from Company:

Hello, We serviced a [Consumer name withheld at their request] on 8/17/18. Replaced parts and gave him a price. The ac worked. We have not gotten a call from you as of yet. If you would like to discuss your issue show me proof another company came and fixed what we didn't. Thank you, 411 heating & AC

Very very expensive, but he knew I needed his help. $300 for 15 minutes of work. Originally I thought my fix would be included in the service call fee of $69, but no. All he did was strip and replace one wire. I feel taken advantage of. I also didn't appreciate all the upselling he did. Buyer beware!

Response from Company:

Hello Mrs. B, You accepted our service to your house. I gave you a price and you accepted the amount prior to the work. If I was too expensive, all you had to do was decline and use your original company you also fired, per your words. Our service fee is $79 not $69. If any company in CALIFORNIA works for $69 for complete job we would all be bankrupt. You spent 8 hours per your words, with Eco bee thermostat and couldn't fix the issue. I spent my professional time, re wiring your work that was not working and made it work. We make it look easy because it?s our job, you paid for what u asked?

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.
