My family has used J&K for well over 10 years for all of our AC and heating needs. My parents use them, I use them personally and we have recommended them to dozens of friends and neighbors. They are prompt, professional, courteous, honest and trustworthy. They never recommend more than you REALLY need, and are always helpful. Additionally, they are kind and give back to the community. This is a GREAT company and I cannot recommend them strongly enough. We use them for regular check-ups, to help with problems, and I have purchased both my AC and Heating units directly from them. They are GREAT!!!!
