5.0 Kayla S. Westland, MI

They also do city certifications in case you have to have your furnace inspected by a licensed person for sale of a home. Great service!

5.0 Felicia S. Belleville, MI

I received a call back right away. The technician arrived on time. A very nice and knowledgeable technician. He solved and explained the problem to me. I'm very pleased with the work that was done.

5.0 James M. Taylor, MI

The technician was very professional, courteous, and seemed to know exactly what he was doing.

5.0 Donald T. Ann Arbor, MI

They were very quick to contact me back and where able to fix our problem the same day on a Sunday.

4.5 Jeri C. Ann Arbor, MI

Very good communication, customer service and accessibility. Took pride in their work and respectful of homeowners space

0.50 Nayef S. Troy, MI

The young tech had no idea where to check, an adder in headlights. He called the office they suggested the control board. I elected to buy the board and installed it. That did not change anything. Hired another provider who diagnosed correctly, no guessing, and no in-necessary parts. Would not recommend Harriman for sure.

5.0 Alexia J. Dearborn, MI

Arrived on time. Explained everything to me. Quick service. Personable technician. Would definitely call for service again. 2 thumbs up. ð ð

5.0 Darius D. Livonia, MI

He was very informative about what I needed

5.0 Nancy J. Livonia, MI

I would definitely recommend this company. I was vert pleased with the customer service, work quality and the value for the cost of the maintenance check. I had the feeling that when the technician left that day, my furnace had been thoroughly checked and it should be running smoothly for the winter season with no worries. The technician, Damon, was very professional and answered all of my concerns and questions. The company also had called a day ahead of time to remind me of my appt and then called the day of that appt to let me know that my technician would arrive in approximately 20 minutes. Before Damon left he also let me know what he thought my furnace might benefit purchasing in the future - which would be a new humidifier . This was not meant to be a purchase I should make right then. Five star!

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.
