5.0 Zachary H. Odenton, MD

When a service tech was sent out, the company sent a text message with both name and photo, which is appreciated. Worked well with out loud, barking dog. Honest and thorough service!


The entire team at Clarksville is very professional, competent, and friendly. They are always very responsive and demonstrate superior workmanship and customer service.

3.0 Jasper K. Laurel, MD

Charged too much money for 15 minutes of service!

5.0 Thomas P. Ellicott City, MD

Darnelle and Ritchie continued with the stellar service we've come to expect from everyone at Clarksville Heating & Air!

0.50 Joy W. Catonsville, MD

They recommended a repair for $600. It worked for a few days. They then wanted me to sell me a new HVAC system for several thousands of dollars. The customer service was poor and they insisted that they did not suggest a repair and refused to give me my $600 back. It was a very hot time of the year. They recognized that I was a senior citizen who could not stay in house with cool air. So they took advantage of me and tried to get as much money as possible out of me. It still breaks my heart to think about how they took advantage on f my circumstances.

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.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.
To find more licensing information for your state, visit our Licensing Requirements page.

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.
