3.5 Ton Heat Pump Split System

3.5 ton heat pump split systems are designed for larger residential spaces and light commercial applications that need dependable year-round heating and cooling. These ducted systems pair an outdoor heat pump with an indoor air handler or furnace coil to provide balanced airflow, reliable temperature control, and improved energy efficiency across larger floorplans.

They’re commonly used for HVAC replacements, home upgrades, and new construction projects where higher capacity and consistent comfort are important.

What you’ll find here

  • 3.5 ton ducted heat pump split systems
  • High-efficiency inverter heat pumps
  • Residential and light commercial heating and cooling systems
  • Matched outdoor condenser and indoor coil combinations
