New Trane Heat Pumps Deliver Full Capacity at 5°F

Trane Technologies has released its first residential cold-climate heat pumps: the Trane 20 TruComfort with WeatherGuard and the American Standard AccuComfort Platinum 20 with All Weather. A heat pump moves heat to warm or cool your home instead of burning fuel, but older models lose heating power as it gets colder outside. These new units are built to hold 100% of their heating capacity down to 5°F and keep running in temperatures as low as -20°F, which means less reliance on backup electric heat strips during cold snaps. They're also designed to work alongside a furnace in homes that want a dual-fuel setup.

The systems come in 3, 4, and 5 ton sizes and use a variable-speed compressor that adjusts output in tiny increments for steadier temperatures and quieter operation. They can also cool in outdoor temperatures up to 115°F. Trane says the units beat the performance targets set by the U.S. Department of Energy's Residential Cold Climate Heat Pump Technology Challenge, and were tested for nearly 18,000 hours in real homes across Minnesota, Montana, New York, Pennsylvania, Wisconsin, and Texas, including conditions down to -21°F.

The new heat pumps are available this fall and pair with Trane Link smart thermostats and indoor air quality equipment for zoned, connected control. They come with a limited warranty covering the compressor for up to 12 years and the outdoor coil and other parts for up to 10 years if you register the equipment. For anyone in a cold climate weighing a switch to an all-electric heating system, this adds another option built specifically for harsh winters.
