Review by in Saint Charles, MO
Project: Repair Natural Gas or Propane Furnace / Forced Air Heating System
Dennis was able to respond to a "no-heat" call at our home within 1-hour after I called Triplett Mechanical to fix our gas furnace issue. He was able to determine the problem and I was actually able to replace the bad pressure switch myself. I would recommend Triplett Mechanical Service to anyone looking for a knowledgeable and honest HVAC service contractor. Dick P.

I was contacted by the company and was actually told what the issue was and how to fix on my own. I will be calling this honest and very helpful company in the near future for yearly cleanings. Love honesty and integrity within a company.

Very responsive. Called immediately after a request for a contractor on Home Advisor. No one else ever called. Worked with my schedule to troubleshoot and repair. Clearly explained options. Completed on time and at the quoted cost. Will definitely call them again first!

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.
