When our central AC stopped working. I called on a Friday morning and was delighted that Darryl came to the house early that same afternoon. Unfortunately, because of our high efficiency system, a new fan motor had to be ordered from the manufacturer and would not arrive until the following Wednesday!!! I was a bit disappointed that although the new fan motor arrived on Wednesday, it was still another day until someone from Superior was available to install it. Also, the installer was a different person that I'd never met before.

Review by in Pelham, AL
We had to have our upstairs heat pump replaced (the downstairs was replaced last year) and because we needed to finance it, we could not use the person who did the first one. We received a few estimates from professionals and Sullivan gave us the most reasonable quote. Tech Daniel showed up right on time and began working while Daryl arrived a bit later with all the equipment. They were finished before we knew it. Even replaced the filter and thermostat. Very professional and didn't leave a mess. I would highly recommend Sullivan. get some quotes from others and you will see why.
Response by Sullivan Service Co.: Thanks for giving us the opportunity. We appreciate your business, if there is anything that we can help you with, please let us know

Technician was 30 minutes early for appointment. Used a different technician to pickup parts to save overall installation time.

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)
