Two summers ago, we had the crew from Atchison install an air conditioner in our house. We went with them, since it was a pretty good price in comparison with other contractors in the area. We bought a Payne air conditioner, since that was the one on sale. It's a division of Carrier, which is nice. Payne air conditioners had mixed reviews, but it's been running like a champ for the summers that we've had so far. The installation is out of the way, and looks good and solid. I'm glad that we went with Atchison.
