ACiQ 3 Ton 13.4 SEER2 Packaged Heat Pump Unit with 10kW Back-up Heat Kit

Best for mid-size homes needing efficient year-round comfort with optional heat backup. This unit integrates cooling and heating in a single outdoor package and uses R32 refrigerant for lower environmental impact. The 10kW back-up heat kit adds resilience in cooler climates, making it a strong choice for regions with occasional cold snaps. Caution: ensure your outdoor space can accommodate a horizontal installation and the included install kit is suitable for your site.
ACiQ 3.5 Ton 13.4 SEER2 Packaged Heat Pump Unit with 10kW Back-up Heat Kit

Better for larger spaces that require robust cooling and reliable heat. With a higher BTU rating, this unit supports bigger rooms or small commercial settings while maintaining efficiency via 13.4 SEER2 and R32 refrigerant. Best for homeowners who want enhanced capacity without adding complexity to the system. Limitation: larger footprint requires more outdoor space and a suitable installation area.
ACiQ 2.5 Ton 13.4 SEER2 Packaged Heat Pump Unit with 5kW Back-up

Ideal for smaller homes or rooms requiring efficient heating and cooling in a compact package. The 5kW back-up heat kit provides an auxiliary heat source for milder cold periods. Choose this if you want a cost-effective, space-saving solution without sacrificing year-round comfort. Caution: heating performance may be limited in very cold climates unless backup heat is engaged consistently.
3 Ton Packaged Heat Pump Unit – 13.4 SEER2 (Oxbox by Trane)

Best for new builds or replacements needing a reliable all-in-one package with standard efficiency. The unit uses R-454B refrigerant and single-stage operation for steady comfort with quiet operation. A good pick for homeowners prioritizing dependable performance over ultra-high efficiency. Limitation: single-stage design may not modulate as smoothly as multi-stage systems in variable climates.
ACiQ 3 Ton 13.4 SEER2 Packaged Heat Pump Unit with Thermostat

All-in-one configuration suited for buyers who want integrated controls. The included thermostat enables easier setup and monitoring. Best for homes where a straightforward, self-contained system is preferred. Caution: verify thermostat compatibility with your existing wiring and control preferences.
Buying Guide
- Capacity vs. space: Choose tonnage that matches your home size and outdoor space. Higher BTU engines require more installation footprint and electrical capacity.
- Efficiency: Look for SEER2 ratings and R32 refrigerant; they influence running costs and environmental impact.
- Back-up heat: Back-up elements (e.g., 5kW–10kW) help in shoulder seasons or colder climates. Consider whether you need auxiliary heat on standby.
- Installation considerations: Horizontal vs. vertical configurations affect clearance, noise, and drip line routing. Ensure outdoor space is adequate for the unit and any install kit.
- Controls: An included thermostat can simplify setup. Check compatibility with existing smart-home systems if desired.
- Maintenance: Access for service, airflow path, and coil protection impact long-term reliability. Some units include dual coil designs for durability.
FAQ
- What is a single-package heat pump?
A single-package heat pump combines heating and cooling components in one outdoor unit, with the indoor distribution handled separately—usually via ducts.
- Is R32 refrigerant better for efficiency?
R32 refrigerant generally provides better energy efficiency and lower global warming potential than some older refrigerants, but check local codes and service requirements.
- Do I need back-up heat?
Back-up heat is useful in colder climates or during heavy cold snaps when backup heat is needed to maintain comfort and freeze protection.
- How do I choose the right tonnage?
Match tonnage to your home’s cooling load, space, and insulation quality. An HVAC professional can perform a load calculation to confirm the best size.
- Can I install a packaged unit myself?
Installation typically requires a licensed HVAC technician due to electrical, refrigerant handling, and permit requirements.
