5.0 Shawn G. Rocky Hill, CT

I found water in my basement and was stressed all day unsure about where it was coming from or who to contact. I went on HomeAdvisor around 9pm and started searching and within 5 minutes someone had contacted me and set up an appointment to be at my condo the next morning. He came and was in and out quickly and fixed the issue.

5.0 Robert J. East Hartford, CT

Had water in basement which I was pretty sure from the condensation pump. I tried making appt with company that installed the a/c but they said a 2 week wait. Went on Angie s list and found AMS who said they were also booked but would try and squeeze me in at end of day if service calls were short. Called back at 4 PM and said a technician would be over. Martin was the tech and extremely courteous and found the problem. It was the condensation pump and needed to be cleaned of blockage. He was in an done within 35 minutes. Fantastic customer service. Pretty sure I spoke with owner originally so both the owner and technician are 5 star in my book.

work was professional and clean

5.0 Veronica M. New Britain, CT

Great experience from beginning to end. Stan reached out to me very promptly after I submitted my request via Home Advisor and got me scheduled asap. The morning of the appointment I received a phone call that Martin would be at my home at 9:00 am and he was. Martin was very helpful and thorough in trying to fix my heating and attic fan problem. Answered all questions I had and gave me different recommendations to address the issues I was having along with different price points. Should I have any future issues I will definitely be reaching out to this company. Personable, informative, punctual, and reasonably priced.

Was not planning on full HVAC system replacement so, surprised by the price. On review, I feel the price was fair. AMS was quick, courteous, and left the job site cleaner than before they started. I would highly recommend this company.

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.
