Be careful with this Service provider. They will do sweet talk over the phone to get you call onsite. They will do the service and will bill you a fortune. For a capacitor that is $25 worth at Home Depot they charged $235. For refrigerent filling they charged me $400 for 3lbs. I had trust on Home Advisor to connect me to a genuine service provider who is reasonable with service charges but after this experience with Sullivan Gas Engineers I will never trust either of them. They totally ripped me off.
Response by Gas Engineers: Hello Mr. Sree, Im terribly sorry that you feel that we were not reasonably priced and that we ripped you off. But, I would like to point out that we provided you with 4 pounds of R-22 refridgerant not 3 and we only charged you $300, the $25.00 Home Depot capacitor you speak of is not the same quality as the one we provided, also remember that just because you can buy something for $25.00 that doesnt mean that's what it will cost you to have someone drive to your location, in a fully equipped, insured, service van with a factory trained technician to diagnose and repair your problem. If the problem was fixed and the machine is operating as it should then you didnt get ripped off you had a proper service call, the price you posted on the capacitor wasn't correct either by the way. You were also informed that it would be a $99.00 diagnostic fee to come and diagnse the problem then give you a detailed quotation of the cost to fix the problem and only after you gave the ok would we do so. If you thought the quote was as bad as you have said it was here then you should've just said no. We work extremley hard to satisfy every customer we have and our reviews other than this one reflect that. Both of your A/C's are 22 years old, both have leaks, and are past due for cleanings. They will probably leak down the refridgerant we just put in and stop working again soon. We informed you of this and that it will happen just so everyone knows, we informed you before we made the repair. I hope you have a great day and if there's anythig else we can do for you or anything we can do to amend this situation in your eyes please let us know.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
