Prompt and courteous service. In fact, service reps at house for both furnace service and general plumbing inspection (all part of service agreement) on the same day. Reps were outstanding!

The One Hours pop-up at the first when I submitted my information to Home Advisor. We are looking for winter maintenance for our two heat-pump systems. When I called for the price, I make sure that the price was for two systems. The technician didn't show up on the first appointment and of course the bad communication was the one to blame. The technician showed up on 2nd appointment and I learned that the price we agreed on was just for one system. It was around 4:30 pm. The outside is getting dark. The technician spent about 15 minutes walked around outside and the basement then wrote a receipt to us. I don't think it's worth of the money to have someone walked around the system and do nothing. It would be nice if there's a clear instruction for what the technician should do for the regular maintenance.

Project: Repair Natural Gas or Propane Furnace / Forced Air Heating System
I received two completely different estimates from their service technicians. One told me I have to replace the furnace and the other replaced a capacitor that fixed the issue. Management is not responsive as well.

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.
