MRCOOL Universal 2 to 3 Ton 20 SEER Central Heat Pump Air Conditioner System
The MRCOOL Universal Series Central Heat Pump and Air Conditioner System is a new and innovative heating and cooling unit that is more efficient, quieter, and easier to install compared to traditional central air conditioner systems.
Unlike conventional heat pump split systems, the MRCOOL Universal uses a DC inverter compressor to regulate performance based on the fluctuating demand. It can scale up capacity when necessary and scale down in favorable weather. This saves you money on energy costs and on maintenance.
The Universal Series Condenser can work with existing air handlers from other brands, but performs best with air handlers from MRCOOL.
The MRCOOL Universal Central 2-3 Ton Heat Pump Air Conditioner System comes with an easy to install, full size air handler and slim condenser, suitable for 2-3 ton (24K-36K BTU) applications. This translates to 1,100 - 1,550 square feet. This system is incredibly flexible, combining the ultimate in ducted comfort and easy installation. The 3 ton condenser can be field converted to a 2 ton with a different dip switch setting. The quick connect fittings on the condenser and air handler allow for an easy installation processes with MRCOOL's pre-charged lines, available as a separate accessory up to 50 feet in length. Using the same inverter technology used by the MRCOOL mini splits, the system can run at different speeds to optimize comfort and efficiency.
We also sell the MRCOOL Universal 4-5 Ton Central Air Conditioner which can cover 2,200-2,750 square feet.
THE MRCOOL Universal Series Heat Pump can continue heating in temperatures as low As -22. The Universal can deliver 100% cooling capacity at temperatures up to 110 degrees Fahrenheit, 80% heat output down to -4 degrees. The air handler comes with an electrical box assembly, a fan motor, a secondary drain pan, a primary drain pan, and an optional auxiliary heat kit.
No-Vac Quick Connect Line Set
The MRCOOL No-Vac Quick Connect Line Set is one of the biggest advantages of the MRCOOL Universal Series Central Heat and Air Split System. This line set is kink resistant, pre-charged with R410a refrigerant, and uses Quick Connect fittings.
The quick connect functionality means that the installation of the Universal System saves you hours, and doesn't require any special tools and equipment.
