5.0 Mike F. Petaluma, CA

Aldo came to the job site the next day after we spoke by phone. He sent a quote for the work later that same day. He completed the project (replacing 2 gas wall furnaces) in a single day and the heaters were working that night. He was prompt, reliable and easy to work with. I highly recommend him.

5.0 Daniel H. Vallejo, CA

On time every time. Totally explained what he was doing. Very patient.

5.0 Matthew B. American Canyon, CA

I received inspection, service and repair in the same day. The technician came, made a determination and procured the part. Returned and installed the part, tuned up the system, and did a quality check. Issue was resolved and I was given instruction about setting up a maintenance schedule to help prevent future issues. The tech (Aldo) was friendly, efficient and explained the problem for my awareness. Fully satisfied, I will recommend to folks I know. Thanks!

5.0 Mike B. Napa, CA

5.0 Jamie K. Martinez, CA

5 stars all the way around. Nice, competent, quick response, Aldo arrived the same day I made a request, he could do a diagnosis and do the job on the spot. Better yet, he was able to repair instead of replace duct work for a fraction of the cost of what other companies could offer.

5.0 Maria R. Vacaville, CA

I am really happy with the service provided by Aldo. He arrived on time and was very polite. I liked how he explained what was wrong and how he would go about repairing it. He have us a great price that couldnâ t be beat by others. The repair was done pretty quickly and Iâ m glad to have my a/c up and running again! I would definitely recommend Aldo and his company

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

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.
