Heating & Air Conditioning / HVAC near Oak Forest

“Jordan the plumber did an excellent job. He was professional, respectful, kind and friendly .He explained all the details as he worked on repairing the toilet. I was amazed and impressed by how clean the work area was after he was finished. He was also consistent with putting on shoe covers each time he came into our house. I give him 10 stars for his service.“

“Excellent service! Friendly efficient knowledge staff. Tim Estimator Alexis Secretary Ryan West and Colin Installation Technicians I have to say everyone I was in contact with was very easy to deal with. I felt bad for the install technicians as it was only 8 degrees outside. They did an all day outside commercial unit install at the house with no complaints. Also did a great job! I highly recommend using them.“

“I worked with Jerry and Precision on installing a new HVAC system, specifically a Mitsubishi mini‑split, and I want to share how impressed I’ve been with the entire experience. Jerry is genuinely one of the best, most professional, thoughtful, and thorough contractors I’ve worked with as a homeowner in Chicago. Before finding him, I had tried three or four other contractors, and he was the only one willing and able to provide a fully itemized quote — something I needed because I was dealing with an insurance claim. Not only did he prepare that detailed estimate, he also took it upon himself to communicate directly with the insurance company. Thanks to his persistence and expertise, he got them to cover the full cost of the job. The project totaled $30,000, and the insurance initially wanted to give me only $20,000, but Jerry managed to get them to approve the entire amount. He also coordinated with my condo management to ensure all the necessary paperwork was handled, especially since a crane was required for the installation. That alone saved me a huge amount of stress. Another thing I really appreciated is that Jerry and his team genuinely seemed to have my best interest in mind. They took the time to walk me through what had gone wrong with the original installation done by a previous company before I owned the place. They explained the safety issues in the piping system and showed me the steps they were taking to correct them — including using stronger, higher‑quality materials to support the outdoor unit and ensure everything was installed properly and safely this time. I also found it incredibly easy to communicate with Jerry — unlike other companies that made me jump through hoops just to get basic answers. He was straightforward, responsive, and always followed through on everything he promised. On installation day, he arrived with a fantastic crew — Chris, Steve, Mario, Ralph and Aurelio. They were all extremely professional, clean, respectful of my home, and very clear in explaining what they were doing throughout the process. They worked with real commitment and care. While I still don’t know yet how the HVAC system will perform long‑term, I’m genuinely pleased and appreciative of the whole experience.“

He checked everything and showed us how to regulate our humidity (which had been too low for us). He also made suggestions for a new thermostat that includes a humidity monitoring option which we are considering. Great service!“

“We have used this service in the past. We always know when they are coming and they show up early, briefed ahead of time, and are ready to work coming through the door. Everyone of the workers we have had the pleasure to meet have been extremely courteous, respectful of us and of our property. Their work ethic is beyond reproach. They are happy to show you what they are going to do or what they have done. If you have any questions while they are working, they will stop, answer your questions with a smile and make sure you understand before they go back to work. The cleanup they do is exemplary. The house is noticeably more quiet and warmer. These folks are a pleasure to work with.“

“We started to have a problem with our furnace on a Sunday night, called first thing on Monday morning & left a message and Jeff quickly got back to me. He and his team member were able to come out and get the parts replaced and got the furnace up and working same day. Great service, reasonable pricing, and great attitude. Also a veteran-owned business!! Thanks!“

“Our furnace went out in one of the coldest days of the year. We called our usual HVAC company we’ve used and no response. My husband called and texted I also called and texted. And till this day we have not received a callback. I called Kings Heating and Cooling they responded quickly and a technician was sent out within 20 minutes. Cole was polite and honest with us. He set us up with a sales rep. Who also came out the same night. Jordan was very personable, funny and he loved our dog Ozzie. We were given space heaters and our furnace was installed within 2 days. Technicians were also professional and respectful. We are very happy with our furnace and humidifier. Needless to say our old HVAC company is no longer on our contact list. A huge thank you to TJ you are awesome.“

“Friendly, professional, informative and efficient, Joe/ Joel was spot on with his expertise. We will consider the other companies’ services when needed.“

“I hired Assured for some AC work after my system wouldn't turn on this summer. I have a fairly complicated 2 zone SpacePak system and after getting multiple bids and talking extensively with each contractor, selected them for their low price (considering I needed a complete replacement due to refrigerant regulations), as well as their thorough explanations of the work and responsiveness. Assured was professional, on time, clean, and explained the work as well as care and maintenance so I understood what they were doing and confident how to maintain the system for the future. I highly recommend them.“

“We had such a great experience with Marek! He was so kind, professional, and made the whole process stress-free. He explained everything clearly, fixed our AC quickly, and made sure everything was working perfectly before he left. On top of that, he was genuinely sweet and respectful, which made the experience even better. It’s not easy to find people who are both skilled and caring, but he was exactly that. Highly recommend!“

“Jacob Anderson the general manager really went above and beyond to explain everything to me about the new HVAC system being installed by my mothers house. Very trustworthy and reputable company. Upholding warranties and very competitive pricing.“
