Welcome to Carlisle HVAC
Manufacturer of Hardcast, Gripnail and DynAir brands.
Kountze Memorial Lutheran Church in Omaha, Nebraska, is a historic landmark requiring careful preservation of its stained glass, organ, and intricate interiors. During a major $1.4 million renovation, maintaining indoor air quality was critical to protect these features. Partnering with Midlands Duct Cleaning, the team used Carlisle’s RE-500 sealant to restore aging air handlers and ductwork. The results included dramatically improved air quality, reduced operating costs, and easier long-term maintenance—completed ahead of schedule.
Read on to see how RE-500 delivered lasting protection.
