The 4 to 5 Ton 17 SEER2 MrCool Universal Central Heat Pump Split System is one of the most high performing, versatile, and simple heating and cooling products available from the industry today. This is a central heat pump that can cool better than most air conditioners, heat better than virtually any other heat pump, compete with traditional furnaces in cold weather, and reduce energy consumption thanks to its sophisticated internal controls. It even comes with new technology that makes HVAC installation faster and simpler than a traditional heat pump. Basically, the MrCool Universal has it all.
But what is in that "all" exactly? Let's start with the installation of the 4 to 5 Ton 17 SEER2 MrCool Universal Central Heat Pump Split System. Normal heat pump split system installation will require an HVAC tech to carefully cut the refrigerant line set to fit, charge with nitrogen, braze the connections, vacuum the lines, and then, finally, charge with an appropriate refrigerant like R-410a. It is an effective process, but it can take many hours to do properly and requires specialized tools.
MrCool Universal Heat Pump Continues to Heat in Temperatures As Low As -22
The 4 to 5 Ton 17 SEER2 MrCool Universal Central Heat Pump Split System is also one of the most effective heat pumps when it comes to performance. The variable-speed DC inverter compressor inside the condenser can deliver high SEER performance and superior production capability. What that really means is that it can deliver maximum cooling and heating at very high and very low temperatures. It will produce 100% cooling at 110 degrees Fahrenheit, up to 72% heating at -5 degrees, and continue producing heat down to minus 22. Most conventional heat pumps begin losing efficiency below 32 degrees.
No-Vac Quick Connect Line Set Compatible!

No cutting, no brazing, no vacuuming, and no charging is required when using the MrCool Universal Pre-Charged Quick Connect Line Set with the 4 to 5 Ton 17 SEER2 MrCool Universal Central Heat Pump Split System. Traditional installation is available for this product, but for those who want something simpler and easier, we highly recommend the No-Vac option. Combining the MrCool Universal split with the No-Vac lines means that installation can be reduced by hours, and the installer will need only half the tools required for a typical installation. This style of install saves time, money, and headache.
