    I had done my research on the ductless AC that I desperately needed for our 3rd floor master bedroom. I recieved several estimates from several companies. This company's sales rep did an honest assessment at a great price. This AC unit is really life changing. I would highly recommend them.

    5.0 James S. Aberdeen, MD

    We have an older home (built in 1940), so competency and fairness in price was very important to us. All of our request was met. All of the employees of SM Mechanical LLC were honest, experienced, friendly, professional and competent. I will be using them again in the future and I highly recommend them.

    4.5 Susan L. Fallston, MD

    We had a couple of scheduling delays but everything was resolved. Jason worked so hard on resolving the delays and kept us in the communication loop. The technicians, Steve and Brandon, that installed the heat pump were incredible. They worked together like clockwork. It is a beautiful installation and is working beautifully.

    5.0 William B. Forest Hill, MD

    The two gentlemen who installed our new air conditioner and gas furnace worked together with incredible teamwork, skill, and attention to every detail. It was quite remarkable to see how skilled they were in the performance of their jobs. They were also both very professional and personable. I highly recommend S.M. Mechanical LLC. to anyone who needs a new air conditioner or furnace.

    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.

    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.
