Heat Pump 3 - 12.5 Ton

These self-contained, all-in-one outdoor units deliver both AC and heat through ducted supply and return. They’re a smart choice for packaged rooftop or ground heat pump replacement, new installs for small to mid-size commercial spaces, and dependable heating and cooling for large homes or multi-family buildings. Downflow/horizontal configurations simplify tie-in when a curb or platform is available.

Choose capacities from 3, 4, 5, 6, 7.5, 8.5, and 10 tons, with category coverage up to 12.5 tons (about 36,000-150,000 BTU/hr). All models use R-410A; SEER2 and HSPF2 efficiencies vary by unit. Expect budget-friendly pricing from roughly $4,340 to $14,190 depending on size and features.

To streamline selection and fit, units are grouped into 3 - 6 Ton (Small Chassis) and 7.5 - 12.5 Ton (Medium Chassis) subcategories. Small chassis models offer compact footprints for tighter curbs and pads, while medium chassis models deliver higher airflow and larger coil surfaces. Professional installation is required. Confirm electrical service, breaker/disconnect, roof curb dimensions, drainage, clearances, and crane or pad access before delivery.

Frequently Asked Questions

  • What size (tonnage) packaged heat pump do I need for my building?

    A licensed contractor should perform a Manual J/S/N load calculation. This ensures proper tonnage, airflow, and electrical sizing for your climate and building.

  • Are these downflow/horizontal units compatible with my existing ductwork?

    Yes, when your system is designed for downflow or horizontal and the curb or platform matches. Transitions or adapters may be needed to meet airflow and static pressure.

  • Do these packaged heat pumps use R-410A and can they replace older R-22 units?

    Yes, they use R-410A. They can replace R-22 packaged units, but verify curb size, electrical, and controls. The refrigerant circuit is self-contained in the unit.

  • What are the differences between small chassis (3-6 ton) and medium chassis (7.5-12.5 ton) units?

    Mainly footprint, airflow capacity, and curb size. Medium chassis models handle higher CFMs and larger coils for bigger zones and higher loads.

  • Is professional installation required for these large packaged heat pumps?

    Yes. Proper rigging, electrical, controls, and code compliance require a licensed HVAC professional. It also protects warranty coverage.

  • What electrical and curb/roof requirements should be prepared before installation?

    Confirm voltage/amperage, breaker and disconnect, level/compatible roof curb or pad, structural support, clearances, condensate routing, and crane access if rooftop.

  • How do I choose between Daikin and Rheem offerings in this category?

    Compare efficiency, footprint, controls, and warranty features. Both brands are proven; selection often comes down to site fit and preferred features.

  • What maintenance is required for packaged rooftop heat pumps?

    Seasonal coil cleaning, filter checks, drain inspection, belt/fan checks, and testing of heating, cooling, and defrost cycles keep performance optimal.

  • Can these units be installed on the ground instead of the roof?

    Yes. Install on a level pad with horizontal duct connections, proper clearances, and weatherproof seals. Follow local codes and manufacturer guidelines.

  • Do these systems provide heat in low outdoor temperatures?

    They heat efficiently in moderate cold. In colder climates, many models accept electric heat kits for auxiliary heat during extreme conditions.
