When a local church in Great Falls needed better comfort control for its congregation, they reached out to us at Halcro Heating and Cooling. Their main concern was cooling, since summer gatherings in the auditorium could get uncomfortably warm. We recommended and installed two Senville ductless mini splits to give them both reliable cooling and the added benefit of supplemental heat during cold spells.

These units use the new R-454B refrigerant, which is designed to be more environmentally friendly than older refrigerants. That means better efficiency and a lower environmental impact, an important consideration for long-term community spaces like this.
On the outside, we kept the installation neat and professional. Line set covers and conduit give the exterior a clean, finished look that blends in with the building. Inside, the church now has modern comfort control without the need for bulky ductwork or major renovations.


Ductless heat pumps like these are a great option for older buildings in Montana where adding traditional ductwork is either impractical or too expensive. They offer year-round flexibility, precise temperature control, and efficient operation, even when the seasons change quickly as they do here in Great Falls.

If you’re considering cooling or heating upgrades for your home, office, or community building, mini splits might be the right fit. Reach out to us to learn more about the options available.
