Why Heat Pumps Are Better for the Environment

Unlike furnaces that burn fuel to generate heat, heat pumps transfer heat using electricity. This means far lower greenhouse gas emissions, especially as the grid becomes cleaner over time. When paired with solar or renewable energy, their environmental impact drops to near zero.

Reduced Carbon Emissions

Switching to a heat pump can cut heating-related CO2 emissions by over 38% compared to gas furnaces.

High Energy Efficiency

Mini splits use high SEER2 ratings to deliver more comfort per kilowatt than almost any other system type.

Lower-GWP Refrigerants

ComfortStar uses R32 and R454B refrigerants, with dramatically lower global warming potential than R-410A.

No Combustion

No burning fuel means no combustion byproducts, no carbon monoxide risk, and cleaner indoor air.

2026 update: R-410A is now phased out for new residential equipment under the federal AIM Act. All new ComfortStar mini splits use R32 or R454B. See our R32 vs R410A guide for the full story.
