“Excellent service! Trustworthy. We will always contact K & J for all of our needs.”
-Happy Loyal K & J Customer -DuPage County
“From Kip’s first visit where he introduced me to his company and presented me with a proposal to the installation of my Trane furnace, K & J Heating & Cooling was outstanding in every aspect of my furnace replacement. He is honest, straight-forward, and reliable. His standard of workmanship and installation procedure is what other furnace companies consider ‘extra.’ I have asked my townhouse association to put K & J Heating & Cooling on our ‘Reliable Tradesmen’ list so the other 200 units here can also have an excellent experience for their HVAC needs.”

“K & J is the only contractor I will allow to work on my system. I have had bad experiences with others including other Trane contractors. K & J is exceptional in terms of the quality of work, honesty, integrity, dependability, and positive attitude. K & J resolved problems caused by a previous contractor.”

“This is our 3rd year with the new furnace. We have it serviced and cleaned once a year, and so far it has been trouble free. When we call K & J, they are good about scheduling our cleaning, and the technician is always professional.”
