Will it work in a cold climate?

Older heat pumps struggled below freezing, and that reputation stuck. Modern cold-climate heat pumps carrying the ENERGY STAR Cold Climate label hold useful capacity down to about 5 degrees Fahrenheit (roughly minus 15 Celsius) and keep working below that, just less efficiently. In much of the country a properly sized cold-climate unit heats an entire house through winter on its own.

How to read efficiency ratings?

Post-2023 equipment is rated with updated metrics. SEER2 measures cooling efficiency over a season, HSPF2 measures heating efficiency, and higher numbers mean lower running costs. These replaced the older SEER and HSPF ratings, so do not compare a 2026 SEER2 number directly against an older SEER figure.

How to choose without getting oversold?

Start with your house, not the catalog. If you have sound ductwork, a ducted air-source system is usually the simplest swap. No ducts, or an addition to heat, points toward a mini-split. Planning to stay 15-plus years with room in the yard makes geothermal worth pricing out. New systems now use lower-GWP refrigerants like R-454B or R-32 as legacy R-410A is phased down, so ask what the equipment uses.
