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 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.’

K & J is the only contractor I will allow to work on my system. I have had bad experiences with others contractors. K & J is exceptional in terms of the quality of work, honesty, integrity, dependability, and positive attitude.

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.
