5.0 Carmen L. Cypress, TX

Mr. Díaz is honest and went above and beyond to be sure my son and I were not left in this artic freeze! Very reliable, with the winter storm Mr. Díaz still came out to make a service call unlike the others who to today have not reached out! Mr. Díaz also helped my brother with his heater doing this winter storm! I highly recommend Mr. Díaz! He has a loyal customer for life! I will always call on Mr. Díaz for heating and A/C services!

5.0 Joe N. Cypress, TX

great service

5.0 Patrick J. Cypress, TX

Mike responded quickly, help explain and explore my options with pros and cons for replacement and repair of three HVAC systems on house. Quote was detailed and clear, and ending cost was as quoted. Replaced three units in one day, crew was well supervised and very courtesy. Wiring and plumbing routing all looked better than the original placement on both inside and outside units. Ductwork had to be rerouted it looked great. All areas were cleaned up.. Highly Recommend Mike Diaz and his team!! Great Service!


Did a great job installing my new AC unit

1.0 Houston, TX

Mr. Diaz came by quickly to diagnose the problem, said he needed to get a part to replace and never returned. This was after we had given him a credit card number and had to cancel the card to ensure we did not receive any charges. He called to apologize two weeks later, long after the repair had been made.

Response from Company:

I never charged this customer for any costs I inccured coming out to his address(s/c, freon). I filled his system with freon to get him temporarily cooling . I could not get parts I needed that Saturday afternoon (parts houses closed). During the week I left a msg on his phone to call me to arrange a time to return with the parts I needed. He did not call me back. I did not take his credit card info. I only charge when I complete the job. He got a free repair

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.
