Bill answered our call for service of â no Heatâ at our condo on Sunday. Came over within the hour , accessed the problem , came up with an immediate temporary fix so we could have heat until he came back the next day with permanent fix. Also pointed out several unsafe issues which he corrected on his inspection. Friendly, professional , prompt service at a reasonable price. Highly recommend, scheduling work with our other home needs. Thank you Bill, respectfully Paul M.

Our second floor AC unit stopped working during the summer. Billy explained the issue to us very thoroughly and was able to replace the unit in a timely manner. New AC unit is working great and we couldn't be happier!

5.0 Ashley P. Coram, NY

We could not be happier with our boiler install. Our boiler broke in the middle of winter and Billy was able to quickly install our new one. He had also previously installed our air conditioning system, which we are very happy with. Great quality work at a reasonable price. Would highly recommend your friends and family.

5.0 Anthony J. Port Jefferson, NY

It was the middle of the summer when my AC decided to break. I called a couple of places and no one was able to come to my place for at least a week. Billy was so professional on the phone and showed up a day after I called him. He was very efficient and diagnosed the issue quickly. My AC was back up and running in no time and my family was extremely grateful. I would recommend him to anyone. He was professional, kind, efficient and if I ever have a problem again I know who to call. You can not go wrong if you choose B.T. !! Thank you thank you

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.
