MrCool Universal 4 Ton Central Ducted Heat Pump Split System - 17.5 SEER2, 100% Heat At -13°F, R454B

MrCool Universal Series 48,000 BTU DC Inverter Heat Pump Condenser Overview

Variable-Speed Efficiency. All-Climate Performance. Future-Proof Refrigerant.

The MrCool Universal Series 48,000 BTU (4 Ton) DC Inverter Heat Pump Condenser is engineered for homeowners who want premium, variable-speed central HVAC performance paired with meaningful energy savings. With a 17.5 SEER2 rating and advanced DC inverter technology, this condenser delivers consistent, quiet, efficient heating and cooling year-round — even in extreme climates.

Variable-Speed DC Inverter Performance

Unlike traditional single-stage heat pumps that cycle on and off, the Universal condenser uses a DC inverter-driven rotary compressor that continuously modulates output to match your home's exact demand. The result: more consistent indoor temperatures, quieter operation, lower energy bills, and reduced wear on components — extending the useful life of your HVAC system.

Efficiency That Pays You Back

With a 17.5 SEER2 cooling rating, 12 EER2, and 9.5 HSPF2-4 heating efficiency (Region IV), the Universal heat pump delivers efficiency that materially lowers monthly utility costs — and may qualify for state energy rebates and federal heat pump tax credits under the Inflation Reduction Act. Pair with any Universal Series Multi-Position Air Handler (UAH series) for a complete, high-efficiency split system.

Future-Proof R-454B Refrigerant

Built for the EPA's 2025 refrigerant transition, this condenser uses next-generation R-454B refrigerant — a low-GWP (global warming potential) alternative to legacy R-410A. That means your investment is protected against future refrigerant availability issues and regulatory changes, and you're contributing to a more sustainable refrigerant ecosystem.

NO-VAC Quick Connect Compatible

Works with the optional MrCool NO-VAC Quick Connect line set (sold separately), which arrives pre-charged and sealed — eliminating vacuuming, flaring, and refrigerant handling. This significantly cuts installation time and complexity, making the Universal system an excellent choice for contractors focused on fast, reliable installs.

Quiet Outdoor Operation

Operating at just 65 dB, the Universal condenser runs quietly enough to install close to bedrooms, patios, and outdoor living spaces without disruption — a significant upgrade over older single-stage central AC compressors that can disturb sleep and outdoor entertaining.

Built to Last

Corrosion-resistant construction stands up to rain, snow, UV exposure, and coastal salt air. Premium components and rigorous quality control deliver years of reliable performance in any environment.

This adaptability gives your HVAC installer more placement options and makes the Universal air handler an excellent choice for both new construction and retrofit projects, including homes with unusual layouts or tight mechanical spaces.

Future-Proof R-454B Refrigerant

Built for the next generation of HVAC, this air handler is engineered for R-454B refrigerant — a low-GWP (global warming potential) option that meets the EPA's 2025 refrigerant transition requirements. Your investment is protected against future refrigerant availability issues and regulatory changes affecting older R-410A systems.

NO-VAC Quick Connect Compatible

Compatible with the optional MrCool NO-VAC Quick Connect line set (sold separately), which arrives pre-charged and sealed — eliminating the need for vacuuming, flaring, or professional refrigerant handling. This dramatically simplifies installation and reduces labor costs, making it an excellent choice for contractors focused on installation efficiency.

High-Efficiency M-Shaped Evaporator Coil

The advanced M-shaped evaporator coil maximizes surface area for superior heat exchange and airflow — improving system efficiency while keeping the unit lightweight. Constructed from 100% aluminum, the coil is corrosion-resistant and built to deliver years of reliable service with minimal maintenance.

Optional Electric Heat Kits

Supports Universal Series Electric Heat Kits (8 kW / 10 kW / 15 kW / 20 kW) for enhanced cold-climate performance or emergency backup heat. Compatible heat kit SKUs for this air handler: UHK08, UHK10, UHK15, UHK20.

Whisper-Quiet Operation

Operating from 33.5 dB at low fan speed — quieter than a standard dishwasher or household conversation — the Universal air handler delivers powerful airflow without disrupting your home. Four variable fan speeds let your installer dial in the right balance of airflow and noise for each zone of your home.
