How is the Universal® Series - Universal?


  • Condenser can replace any R410A condenser of equivalent capacity using the existing Flare connection or included Flare-to-Weld kit
  • OR Replace the whole system and connect to the Universal® Air Handler using our No-Vac® Quick Connect® Line Set
  • Air Handler has Multi-Position Installation (Upflow, Horizontal)
MRCOOL Universal is Quiet and Compact
  • Compatible with any third party thermostat including NEST
  • Compatible with any third party R410A Air Handlers
  • OR optimize your system with the Universal® Air Handler and our feature-rich smart-app Universal® Thermostat
Third Party Compatibility
  • Comes in four capacities in two form-factors for optimal coverage from 1000 sqft to 2500 sqft
  • Can replace larger / louder condensers where sound / space limitations apply
  • All-Climate application - Exceeds Conventional Heat Pump Performance Ranges
  • Install anywhere where you have ductwork...
  • Slim design allows the customer more lot clearance and the reseller more inventory space in warehouse
Two Models to Cover 24K-60K
MRCOOL Universal is Quiet and Compact

Quiet & Compact - Ideal for:


Zero Lot Line Homes
  • Side discharge design takes less than half the area of conventional condensers
  • Perfect for city lots and between building applications where access is limited
  • Decibels (dBa) are logarithmic - for every 10 dBa a sound is twice as loud - making a conventional condenser at 73 dB(a) twice as loud as the Universal at 62 dB(a)
  • It's the diference between having a conversation and running a vacuum cleaner
  • The Universal emits a soft soothing sound that fades into the background
  • Tired of dependending on fuel oil or propane prices and delivery? This is a solution.
  • Condenser can replace any R410A condenser of equivalent capacity using the existing Flare connection or included Flare-to-Weld kit
  • OR Replace the whole system and connect to the Universal® Air Handler using our No-Vac® Quick Connect® Line Set

Efficient Temperature Regulation


Universal Efficient Temp Control

A DC Inverter system moderates compressor motor speed while regulating temperature.

This eliminates extreme fluctuations in the operating load, extending component life and delivering increased efficiency compared to previous generation technology.

This means lower operating costs, more comfortable climate control and fewer breakdowns.


NO-VAC® Quick-Connect® Pre-Charged Line Set


Kink Resistant for Easier Bending During Installation

100% Accurately Precharged R410A Refrigerant standard sizes: 15 ft, 25ft, 35ft, 50ft

Optional No-Vac® Couplers can be used to combine two standard line sets to extend the length if needed

Simple to Use, Leak Proof, and Screw-on Quick Connect Valves do not require vacuuming

Quicker Installation than Conventional Line Sets

Strong 3/4" Gator-Flextra™ UV Protective Insulation provides extra protection against sun damage, weather erosion, or destruction from animals or insects
