Experience unmatched heating and cooling with the MRCOOL® Universal® Series Condenser. This state-of-the-art system is elegantly designed with a slim profile, ensuring it fits seamlessly into any space.

The DC inverter compressor at its core delivers dynamic heating and cooling performance. It's crafted to provide 100% heating capacity down to -5°F (-20°C) on 2-ton models and 14°F (-10°C) on 4-ton models. Conversely, on warmer days, you can expect 100% cooling capacity up to 115°F (46°C) on 2-ton models and 109.4°F (43°C) on 4-ton models.

One of the standout features of the Universal® Series Condenser is its connection versatility. It offers three types:

  1. The patented pre-charged No-Vac® Quick Connect® Line Set*, available in lengths of 15 ft, 25 ft, 35 ft, and 50 ft, with couplings also available for added convenience.
  2. The traditional Sweat Braze Connection.
  3. The reliable Flare Connection.

For those requiring extended lengths, MRCOOL® No-Vac® Couplers are available. These optional components can be combined with two standard Quick Connect® Line Sets. These optional line sets come in standard sizes of 15 ft, 25 ft, 35 ft, and 50 ft and are also precharged, ensuring a seamless installation process. Moreover, the Quick Connect Valves are simple to use, leak-proof, and do not necessitate any vacuuming, assuring a quicker installation than conventional line sets.

Adding to its adaptability, the MRCOOL® Universal® Series Condenser supports Multi-Position Installation, allowing both Upflow and Horizontal configurations.

The system is available in sizes of 2-3 Ton or 4-5 Ton. And for those desiring flexibility, the condenser can be field converted from 2-Ton to 3-Ton or 4-Ton to 5-Ton using a simple Dip Switch setting. Detailed information is available in the product manual.

When it comes to compatibility, the MRCOOL® Universal® Series Condenser is unparalleled. It's designed to integrate with any third-party air handler and thermostat, including the MRCOOL Universal WiFi Thermostat and the favored WiFi/Nest.

For the eco-conscious homeowners, the system has been designed without the need for a gas furnace and employs the environmentally-friendly R-410A Refrigerant. Furthermore, the condenser comes 100% accurately precharged to ensure optimal performance.

Durability is never in question with the Universal® Series Condenser. Mirroring the robust nature of the entire Universal lineup, this condenser boasts Gold Fin® Technology for superior protection of coils against corrosion. The installation process is further streamlined with its kink-resistant design. To top it off, the 3/4 inch Gator-Flextra™ UV Protective Insulation fortifies the system against sun damage, weathering, and potential threats from animals and insects.

Homeowners can enjoy peace and quiet, as the condenser operates silently within a range of 55-58 dB(a). And for ultimate confidence in your investment, the MRCOOL® Universal® Series Condenser is backed by a 10-Year Limited Warranty.
