Common Questions

Technical answers from our engineering team on system selection, efficiency, and service coverage.

Our inverter-driven heat pump line achieves SEER ratings from 15 to 20, with IPLV values as low as 0.55 kW/TR at part-load conditions. Fixed-speed models range from SEER 14 to 17. All units carry AHRI certification and meet ASHRAE 90.1 minimum efficiency requirements.

Yes. Our heat pump and condenser lines are available with R-410A, R-32 (GWP 675), R-454B (GWP 466), and R-290 (propane, GWP 3) depending on capacity and local regulations. We provide a refrigerant transition roadmap for each project to help you plan ahead of HFC phase-down deadlines under the Kigali Amendment and EU F-Gas Regulation.

Standard warranty is 5 years on compressors and 2 years on all other components. Extended warranty plans cover up to 10 years on compressors and 5 years on heat exchangers, evaporator coils, and controls. Warranty terms include parts, labor, and refrigerant recharge where applicable.

Standard heat pump and condenser units ship within 6-8 weeks from order confirmation. Custom-configured systems require 10-14 weeks. We maintain regional inventory at our 5 production bases to reduce lead times for high-volume models. Expedited delivery is available for emergency replacement scenarios.

Our communicating thermostat and sensor lines support BACnet, Modbus, and LonWorks protocols for integration with all major BMS platforms including Johnson Controls, Honeywell, and Siemens. Our controls team provides commissioning support to ensure seamless data exchange and setpoint management.

Inverter models deliver 30-50% energy savings in buildings with variable occupancy and fluctuating thermal loads, such as offices and hotels. Fixed-speed units cost 20-30% less upfront and are better suited for constant-load applications like industrial process cooling or cold storage, where the compressor runs near full capacity most operating hours. Our engineers evaluate your load profile to recommend the option with the lowest total cost of ownership over a 15-year lifecycle.
