Complete Home Comfort Bundle
This bundle pairs the Merit® Series ML16KP2-048-230 two-stage heat pump with the CBK45UHVT-048-71 variable-speed air handler and the ECB45-15CB 15 kW electric heat kit. Together they form an AHRI-matched, all-electric system for year-round heating and cooling in your Dallas-area home.
AHRI#: 218630628
SEER2: 16
EER2: 12
SEER2 16, EER2 12 and HSPF2 8 Ratings
As a matched system, this 4 Ton heat pump and air handler are rated at SEER2 16, EER2 12 and HSPF2 8, with 47,000 Btuh of cooling and 43,000 Btuh of heating at AHRI test conditions. This matched system is ENERGY STAR® certified. It uses R-454B refrigerant, which meets the 2025 EPA rules for lower global warming potential refrigerants.
Two-Stage Heating and Cooling: ML16KP2-048-230 Heat Pump
The ML16KP2 two-stage scroll compressor runs at about 67% of its full capacity in mild weather and steps up to full capacity on the hottest and coldest days. Longer, lower-capacity cycles keep indoor temperatures steadier and remove more humidity in summer. The Quantum™ Coil uses a corrosion-resistant aluminum alloy, and the precision-balanced direct-drive outdoor fan keeps sound levels as low as 77 dBA.
Consistent Airflow: CBK45UHVT-048-71 Air Handler
The CBK45UHVT variable-speed blower keeps airflow consistent to prevent temperature swings. Its all-aluminum Quantum™ Coil resists corrosion, the fully insulated cabinet reduces sound and helps prevent cabinet sweating in humid weather, and the antimicrobial drain pan resists mold and mildew. A built-in Refrigerant Detection System (RDS) stops the compressor and runs the blower if it senses a refrigerant leak.
Backup Heat: ECB45-15CB Electric Heat Kit
The ECB45-15CB adds 15 kW of electric heat for the coldest days. Helix-wound nichrome elements sit directly in the airstream for fast heat transfer, each element has its own limit control, and the factory-wired circuit breakers protect against overloads and can serve as the disconnect at the unit in many areas.
Who This System Is For
Homeowners who want a step up from a single-stage heat pump: quieter low-capacity operation, more even temperatures and better summer humidity control, in one complete all-electric bundle.
