MrCool Universal Series 24,000 BTU DC Inverter Heat Pump Condenser Overview
Variable-Speed Efficiency. All-Climate Performance. Future-Proof Refrigerant.
The MrCool Universal Series 24,000 BTU (2 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 18.6 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 18.6 SEER2 cooling rating, 12 EER2, and 10 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 59 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.

MrCool Universal Series 24,000 BTU Multi-Position Air Handler Overview
Whole-Home Comfort. Flexible Installation. Future-Proof R-454B Refrigerant.
Upgrade your central HVAC with the MrCool Universal Series 24,000 BTU (2 Ton) Multi-Position Air Handler — a versatile, high-efficiency indoor unit engineered to pair with any R-454B-compatible condenser for whole-home heating and cooling. Whether you're replacing an aging system or installing new HVAC equipment, the Universal air handler delivers the flexibility, performance, and long-term durability homeowners expect from a modern central HVAC system.
Multi-Position Installation Flexibility
Supports upflow, downflow, and horizontal installations — fitting easily into attics, closets, crawlspaces, basements, or mechanical rooms. 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 (5 kW / 8 kW / 10 kW / 15 kW) for enhanced cold-climate performance or emergency backup heat. Compatible heat kit SKUs for this air handler: UHK05, UHK08, UHK10, UHK15.
Whisper-Quiet Operation
Operating from 33 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.

Who installs the AC unit after I purchase it?
ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.
Here’s how it works:
- Hire a licensed HVAC technician in your area
- Use platforms like Angi, Thumbtack, or a local HVAC directory to find reliable professionals
- Confirm your installer is experienced with the system type you’re purchasing
Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
