Mark Koenigseder of J&K Heating & Air in Fort Smith, AR grew up in the heating and air business, as a second generation Fort Smith HVAC specialist. Some things have changed since the Koenigseder family started working in this field. Mark founded J&K Heating & Air to add an energy efficient, eco-friendly approach to the trade. Weatherization and insulation can cut your energy use and utility bills significantly, and weatherization programs can make weatherization an economical choice. J&K Heating & Air will work with you to make the most economical and energy efficient choices. Some things never change, though. Mark believes, just like his father before him, that heating and cooling are important. He doesn’t take shortcuts. For example, every job begins with Manual J heat load calculations. Only 2% of heat and air companies actually take the time to do this, but it’s essential when you want the right comfort level without wasted energy or extra cost. Mark will tell you exactly what you need to make your house a HOME based on what your concerns are, in a way that makes sense to a non-specialist, so you can feel confident about the decisions you make for your home and your future. You can feel comfortable, too, with having our workers in your home. We’re a local company with deep roots in the River Valley. We also maintain a drug-free workplace. The work that J&K Heating & Air does in your home is guaranteed, and J&K Heating & Air provides 24-hour emergency service.
