Product Overview

Multi-Zone Comfort Designed for Colder Weather

The Carrier Infinity Multi-Zone High-Heat Ductless System is designed for homeowners who need efficient heating and cooling across several rooms without installing extensive central ductwork.

The Infinity 25, model 37MGHA, connects one outdoor heat-pump unit to multiple compatible indoor units. Each indoor unit serves an individual room or zone, allowing different areas to maintain their own temperature settings.

Its variable-speed compressor adjusts output to match changing demand rather than repeatedly operating at full capacity. This supports more consistent temperatures, quieter operation, and efficient year-round performance.

The system includes a basepan heater that helps manage ice and moisture around the outdoor unit during cold weather. Carrier states that the system can maintain 116% heating capacity at 5°F with an appropriate size and system combination. It offers up to 25 SEER2 cooling efficiency and up to 11.3 HSPF2 heating efficiency.

This System May Be Right for You If:

  • You need heating and cooling in several rooms.

  • Your home does not have traditional central ductwork.

  • You want stronger cold-weather performance than a standard ductless system.

  • Different occupants prefer different room temperatures.

  • You are upgrading an older home, addition, basement, attic, or converted garage.

  • You want variable-speed operation and multiple indoor-unit options.

Frequently Asked Questions

Get answers to common questions about the Carrier Infinity High-Heat Ductless System.

What makes this a high-heat ductless system?

The system is designed to maintain stronger heating capacity during colder outdoor conditions. Carrier states that the 37MGHA can maintain 116% heating capacity at 5°F when properly sized and matched.

The Infinity 25 can connect to as many as six compatible indoor units. The appropriate number depends on room sizes, heating and cooling loads, and the selected outdoor-unit capacity.

Yes. The system works as a ductless heat pump, providing cooling during warmer weather and reversing operation to deliver electric heating during colder conditions.

The basepan heater helps reduce ice accumulation and manage moisture around the outdoor unit during low-temperature heating operation.

No traditional central ductwork is required. Each indoor unit connects to the outdoor unit through refrigerant tubing, electrical wiring, and a condensate drain.
