5.0 Deborah B. Evergreen Park, IL

We had an HVAC system that was very old and were told not to "put any more money into the furnace" and the a/c unit died about 4-5 years ago, so we finally decided to get quotes to replace the whole system, inside and out. We received several quotes, but I really got a great vibe from Mr. Nelson at Certified Heating LLC. From the very beginning, he was very forthright and down-to-earth, which I appreciated. He told me to call anytime if I had any questions. His quote was the best and since I really connected with him, we decided to go with him. His men were out ASAP, were courteous, professional and made sure everything operated exactly as it should. Mr. Nelson came by to make sure I was happy with the work done, and I know that we made the right choice. Choose Certified Heating LLC for all of your HVAC needs....you will not be disappointed!!

Keith Nelson was professional and took the time to explain what I needed and why. The was no pressure or fast talk. His men arrived on time and appeared to be very knowledgeable. They were efficient and left their work area neat. I would use this company again.

5.0 Rona H. Matteson, IL

My furnace was leaking excessively. I spoke to Keith Nelson and he came out and assessed the problem on a Saturday close to closing. A contractor came the next morning and fixed the problem charging a nominal fee. I highly recommend this company!

5.0 Deborah L. Chicago, IL

Keith Nelson and his team did a great job diagnosing that I needed a new Heater and working with American Home Shield to get the heater covered. They also offered me and installed a number of additional items to my heater, humidifier, air filter, to meet my needs. They are courteous and responsive. And, their prices were almost half the cost of Four Seasons! They are my new heating and air conditioning company!

5.0 Marjorie M. Chicago, IL

The installers were very courteous and professional. The owner and project manager kept in touch with me throughout the installation. I am very pleased with the work performed in my home. I look forward to the annual maintenance that they will be providing. I will certainly recommend this company to others looking for this type of service.

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.
