5.0 Wilber B. Novato, CA

Randy is great to work with and really professional!

5.0 Kay T. Vallejo, CA

They fixed a problem we had for years and had asked others to fix but everyone said it was unfixable. We did not have heat to 1/2 of the house. VOLKMAN got under the house and found vents that had bern disconnected. He got in and fixed it at a very reasonable price cutting our heating bills by 2/3rds

5.0 Steve W. San Rafael, CA

Randy and his helper were very good to work with. They arrive when they say and the follow through with the install was flawless. System worked exactly as offered. The attention to detail was greatly appreciated!

5.0 Wendell M. Rohnert Park, CA

Randy was quick to call us back. Although our problem was not urgent he was there Monday 9 am! Our furnace fixed quickly and honestly! Very reasonable fee so we will use him again and recommend him to our friends. Thank you randy!

5.0 Maria D. Novato, CA

We had such an excellent experience with Volkman heating. We needed a mini split unit installed in our upstairs level, where we have high ceilings. Randy and his team did the install quickly and everything turned out perfectly. We were so happy with their customer service and the whole experience from start to finish. Very rare here in Marin County.

5.0 George T. Corte Madera, CA

The job was done quickly, efficiently and we no surprises. The price quoted covered the entire job without any surprises.

5.0 Donald I. Greenbrae, CA

Randy, company founder was very professional. Installation was done with exceptional quality.

5.0 Rob D. Castro Valley, CA

I hired Volkman Heating and Air to install a heat pump system for three rooms. That was all I wanted. But, when they were finished, I decided to have them do the rest of the house as well. Anyone can promise you great, professional service. Itâ s rare that they actually deliver everything they promise without compromise. Thanks! Iâ m now ready for the heat of summer to begin.

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.
