Jack, the technician, did not go over the 30 pt system check with me.
Response by DD Mechanical Services: Larry I am very sorry to hear that Jack did not go over any finding on the Spring Check up with you. I've been able to talk to the tech about this. He assured me that after explaining several deficiencies and problems (ductboard plenum starting to fail and run capacitors leaking etc... ) and you watched him as he did the check up. He felt he covered every thing. If he did miss anything please call my office at 281-XXXX so I can go over this more through with you.

AC quit on Friday night. 1st company quoted complete new system at $5k. Called DD Mechanical spoke with David who assured me they could be trusted to diagnose the problem as they have been in business for many years and only perform honest work. Billy & Edward showed up Monday morning and delivered on David's promise. They quickly identified the real problem: a dead capacitor and fan motor. They fixed both and we had cold air flowing in no time, at a fraction of the cost, to the happiness of all in family. Thanks to David, Billy and Edward!! Will definitely use them again in an emergency and for regular service.
Response by DD Mechanical Services: We try to treat everyone like family.

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.
