Very efficient, very polite. Job was completed without any mess or inconvenience, and the inspector said it was very well done. The red tape surrounding the permit was horrendous, due to the city's overworked application site, and I would have liked more help with it, but all in all, very accommodating.

His diagnosis did not resolve the issue. And It cost me $800. Material was only 100and the labor which was 700 was less than an hour. I believe replacing the inducer should have been only 300. Got someone else for 1500 for a brand new unit. He gave 4500 quote for the same thing. 300%

Really prompt service. Came on Thanksgiving weekend to help us when our heat went out and it was 40 degrees outside. Managed to fix the ancient heater in our house in under an hour and also pointed out problems with the installation in general (new house, to us, anyway) and made recommendations to fix when we do some other work. Totally recommend.

I had called our usual heating company about the fact that our furnace shut off on Christmas day. On Saturday the 26th, they said they could send someone on Tuesday. When I complained they "generously" offered Monday. I called 411 at 8:30 am Saturday. Sayeed said he could come between 10am and 12pm that day. He came at 11. Found the problem, fixed it, and was gone by noon. He was friendly. Knew what he was doing. And clear in explaining. Fees were reasonable. We'll be using 411 for our heating needs.

Very impressed with knowledge of the technician who performed the work as well as the quality of the work that was completed. The technician also provided the highest level of customer service and safety for the duration of his being on-site.

Everything about dealing with 411 was great. I don’t have my floor furnace worked on very often so I don’t have anything to compare to but it seemed very pricey for the amount of time and parts that were involved.

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.
