What a Flat Rock customer said
Our A.C. went out on us recently and we contracted with J&K to do the work and get it up and running again. Technician Isiah responded and did a wonderful job of fixing the problem, explaining things, was very thorough, professional, and personable. Isiah set us up with a plan through the company for maintenance at a very reasonable annual cost which saved us a considerable amount with this service call. Hats off to J&K and to Isiah for a job well done. Yes, I would recommend this company.
