Heating & Air Conditioning / HVAC near Lemont Furnace

“We called Gibbs on a Sunday afternoon, he returned the call a few hours later and was literally a half hour later. He could have charged for an emergency appointment but did not. (We would have paid that, it was 90 degrees in our house.). He fixed the issue quickly and even took the time to show me how to take the sides off of the unit and told me what to buy and exactly how to clean it, but did tell me if I wasn’t comfortable doing it myself to just give him a call and he would come back out and do that as well. Very professional and respectful. He could not have been nicer. If you need anything done with an air conditioner he is definitely your man.“

“They came out to service my furnace the same day I called. The employee's name was Adam and he was fantastic. He has a genuine personality and I appreciated how he explained everything he did.“

“If someone asked me for a swim spa recommendation I would simply say one name: Chad Elza. In April 2023 he coordinated and executed the delivery and install on our swim spa and everything went according to plan even though he couldn't physically be there due to unforeseen circumstances. I believe that speaks volumes to the level of professionalism and dedication he has toward his job. He has definitely fostered strong working relationships with all the vendors he uses to the point that even in his absence all moving parts worked effortlessly together. From day one he has been so attentive and promptly answered all my questions and concerns and leading up to the morning of delivery he walked me through the whole process and made me feel so comfortable with the install. It's a true testament to his work ethics and attention to detail. Fast forward to now, there have been a few functionality issues with our unit, no fault to Koval, and yet again Chad has worked with me promptly to get us back up and running each time. It's easy to give high praise when everything goes flawlessly, however I think it's more worthy for the praise when things go south and you get to experience what true quality customer service looks like when you need it the most. Thank you to Chad and the Koval team for all you do day in and day out!“
