Since my old house used to be very cold in winter, we decided to install a floor heating system. Mr. Seo provided us with a detailed explanation of the systemâ s benefits, and he was very supportive during the installation process. Highly recommended to work with him!

My project is to add two rooms for my teens as their rooms are very small. Central furnace was not good for the health so I was searching for other options, and found out radiant floor heating system. I compared a few vendors but was not very happy about others option and cost. Then I came across Namu Hydronic Systems offered by Namuhousing company. I tested their panel which is based on Koreaâ s traditional technology and modern version. Their work was pristine and very efficient. It took a day or two to finish the job. Once I plugged the small boiler to wall outlet, it worked like a charm. Boiler is compact enough to wall mount inside of closet! No more furnace noise, no more dust in the air which is best part for my kids health!! Each room has temperature controller on the wall 3x5 inch and boiler need only a gallon of water. Each room size that We added wa about 160 sqft and we had a pleasant winter thanks to these new heatin systems from the Namu housing. I am very satisfied customer. Highly recommend this heating system and company.

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.
