5.0 Ernest P. Hanover, MD

I was shown all options that would suit my house. Contact was maintained during the order stage and I was advised as soon as installation was ready. The complete HVAC system was replaced. The installation was efficient and the crew was courteous and careful, protecting my floors with drop cloths. They cleaned the area were they worked and removed all residue.

5.0 Loretta A. Clarksville, MD

I would hire Clarksville Heating & A/C again.

5.0 Robin T. Brookeville, MD

I had a complete new HVAC system installed in the attic of my house threw access in small bathroom - no problem for these experts. From the salesperson to office staff to the installers, I found them to be professional, courteous, patient, friendly and just generally good people. I have had no issues where I had to call the company back - appreciated this so much I sent salesperson a note of appreciation. Clarksville Heating and Air, LLC will be my go to for all HVAC matters. Phenomenal company to work with - so glad I found them.

4.0 Michael N. Crownsville, MD

Very pleased with the work, affordable and communication was good. I gave a 4 star because they were a little late.

5.0 Arthur G. Columbia, MD

Clarksville Heating and Air have performed routine maintenance for our A/C for several years and now our heating system. Marco discovered a problem with A/C during inspection. He reported the issue, ordered the part and had it repaired in less than 48 hours. Marco and Clarksville went the extra mile to make sure the system was repaired and functioning. The have always responded quickly to any inquiry and I would highly recommend them for anyone's A/C and heating system needs. They are highly-qualified, thororough, professional, efficient and customer oriented.

5.0 Dori S. Catonsville, MD

Everything went smoothly, quickly, and at a reasonable cost. We couldn't be happier!

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

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.

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.
