The technician arrived within the first hour, he was polite and respectful of my home. He showed a vast knowledge of my HVAC system and was eager to answer questions and share his knowledge. I am very satisfied with my system and King Heating and Cooling.

Very professional and pleasant technician. Recommend King for all of your infrastructure needs.
An on time company with excellent customer service. A very personable and professional service person. Explained what was needed without a pressure sales pitch. I trust in their service with the cleaning service I received. I recommend and will definitely use their services in the future 👍.
Service was great, tech very friendly and knowledgeable. DID come on a Sunday! Would recommend company/him highly, they are my go to for plumbing needs now
My plumber was very polite and professional. He came out the same day that I called. Price was reasonable.
Called at 7am. Technician got there at 9am. Figured out the problem had the part in his car. Fix and ready to go in 1 hour. Absolutely the best. Thank you Jesse. Would highly recommend this company.
I received the best service from Nick Mejia on Sunday, 2/16/2025. Nick Mejia fixed the big problem “Gas Leaking” and saved my life.The “Gas Leaking” created by one plumber from King Heating, Colling & Plumbing on Friday, 2/14/2025. The plumber came to fix the Water Heater but created the “Gas Linking”. I had to call Wilmette Fire Department come to my house on Saturday, 2/15/2025 to check the “Gas Leaking” and Fire Department checked and saw the ‘big Gas Leaking in my house’. The Fire Department had to shut down the Water Heater on Saturday so I can stay alive. Nick Mejia called me on Saturday, 2/15/2025 and he said he could come to check my house around 5:00pm. I told him to come on Sunday, 2/16/2025 morning to check out the Water Heater. Nick came on Sunday, 2/16/2025 around 9:00am and he checked the Water Heater and he showed me he did see the “Gas Leaking”. I am very luck to have Nick Mejia came to fix the gad leaking and turned on the Water heater. Th Water Heater is working correctly now. I wanted to say “Big Thank you to Nick Mejia to save my life”. He is an excellent plumber and he knows how to check the problem and fix the problem. This is a big lesson learned for everyone. Because if I did not go out on Saturday morning then I would not find the “Gas Leaking” inside the house and probably caused my life to the death. I hoped your company to continue to educate your plumbers to do the correct work for the customers and always checking the Gas Leaking” issue before they go home. Thank you. Pang

Featured Review of King Heating, Cooling & Plumbing by Brian W. on Google

Jordan came and gave us an estimate on Monday, July 8, 2024. He explained the issues that were being caused by our current heating and cooling systems within our home. The system that came with our home had went out two weeks prior and the home warranty was jerking us around. However, King Heating, Cooling and Plumbing didn’t do that from the estimate to installation. They walked us through the permit requirements for our village and the installation of our new furnace and ac was installed on Wednesday, July 10, 2024. Thank you for helping us make the right investment and decision for our home. Thank you for the excellent customer service and professionalism. Jordan is awesome! We are pleased and finally back cool!
