“Mendel was able to get someone out quick 2 days before Christmas to take a look at my water heater. Jesse was up front about cost expectations and what work he’d be doing. He was quick and very helpful!“

“Just want to give a shout out to the staff of this company. I called 5 companies when I needed help with my AC in one of the crazy hot days in Illinois and I know it was a holiday and I was certain nobody will show up but even if it was a holiday one particular person responded, I found out later, he was the owner. I was grateful with the response even if (again) I already know things will not happen that very day, the response made the difference. The following day, a kind young lady called me and asked if I still needed help and see if we can schedule a visit to check my system. The system they use for customer to track the service team is excellent. The best part was Jeff, he is kind and patient with my questions, he took time with needs to be done and OFFERED OPTIONS, I know it is a business however I believe we can still maintain being human rather than just doing a job to get paid and that is how I feel with this company. That being said “ Grateful and thankful for the service “. Wish you continue to serve the community with grace and patience.“

“Bruce and Roy are always on top of everything and make sure everything is working well and that things won’t go out when it is cold or hot!!!“

“Will definitely use these guys again Great work and peopleServices: Heating system installation“

“Jamie was terrific. Very personable, explained what went wrong and why, fixed it quickly and cleaned up before he left. I told him to leave me several cards and we now have them plastered around plumbing in the house so we know to call these guys next time.

I had two other bids to replace my ejector pump. One was $1600, one was $1200, and Wagner came in at $1020. They were also able to get someone here less than 24 hours after I called. HIGHLY RECOMMEND!“

“Todd from Cool Operator Heating & Cooling Inc. came out to diagnose our furnace issue from AHS . He took the time to properly identify the problem and fixed it by replacing a part. I really appreciated that Todd focused on repairing the furnace instead of immediately suggesting a replacement just because of its age. Very satisfied with the service!“

“As always Mark came through for me!! Not only was it the hottest time of the season, but I also had overnight guests…and it was a Sunday! Mark called me back within half an hour and was at my home early the next morning. He worked his magic and I now have a brand new air conditioner. I have been a long time customer of Mark’s. Now even my neighbors call Shark Heating and Air, because Mark is so thorough, competent, professional and timely. Thank you, Mark!!!“

“Klinkey did an outstanding job. Not only did he fix our water boiler, but he did so in a professional and timely manner. He was on time and explained what the problem was, and the best way to go about fixing it. He cleaned up after himself and didn't leave a trace other than a fully functioning water boiler. Would recommend Klinkey Heating & Sheet Metal for any job you need!“
