5.0 Jan and jeremy P. Pasadena, MD

We met with a few HVAC installers and Supreme Air quoted the lowest prices and gave us 3 options to choose from. No games, no pressure tactics, and no unexpected charges. They were very prompt, professional, and did a great job.

4.0 Gary S. Millersville, MD

I also needed a chimney and they coordinated with the chimney company which made this easier for us.

4.0 Chris D. Severn, MD

Job was done at beginning of COVID pandemic. They followed all safety measures. Crew was on time and thorough.

5.0 David C. Severna Park, MD

Paul was our plumber - very nice, professional and great conversationalist. He diagnosed the source of our stoppage, and was correct. Did the service in an hour, clearly told us the cost upfront, and then did the work to our -- and his -- satisfaction. Called when he left the shop, arrived exactly when he predicted, and got right to it. Very satisfied to have Supreme out again - I could not remember when they were here before, which Paul said was a good sign. Great service.

Supreme Air, LLC

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.

To find more licensing information for your state, visit our Licensing Requirements page. Note that some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
