Benefits & Features
The Future of Central Heat & Air
MRCOOL Universal® Series Heat Pump A/C Condensers & Systems
Much Quieter
Ideal for Sound Restrictions
For every 10 Decibels (dBa) a sound is twice as loud - making the Universal® at 55 dB(a) less than half as loud as a conventional condenser at 73 dB(a).
Slim Design
Ideal for Zero Lot Lines
Side discharge design takes less than half the area of conventional condensers. Perfect for city lots and between building applications where access is limited.Versatile Installation
Truly Universal Installation Options
The Universal® has Flare, Flare-to-Weld or No-Vac® Quick Connect® line set options and Multi-Position Air Handler Installation (Upflow, Horizontal).All-Climate Performance
NOT Your Typical Heat Pump

Thermostat Compatibility
Truly Universal Thermostat Options
Compatible with any third party thermostat including NEST®OR optimize your system with our feature-rich smart-app Universal® Thermostat
Reliable Comfort
This DC Inverter Does It Better
The Universal® DC Inverter moderates operating load, heating & cooling with less fluctuation for more comfortable climate control, extending component life for fewer breakdowns.
Side Discharge
No Clogging / Less Space
The Universal® takes half the area and, unlike conventional condensers, doesn't fill up with leaves, snow and debris.
Versatile Application
Install Almost Anywhere
Replaces larger / louder condensers where sound / space limitations apply, and exceeds conventional heat pump performance ranges for All-Climate applications with optimal coverage from 1000 sqft to 2500 sqft.Energy Efficient
Up to 20 Seer
The Universal® DC Inverter moderates operating load, increasing efficiency for lower operating costs.
Gold Fin® Condenser
Corrosion Resistant

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
Strict Sound Restrictions
- Decibels (dBa) are logarithmic - for every 10 dBa a sound is twice as loud - making a conventional condenser at 73 dB(a) more than twice as loud as the Universal at 55 dB(a).
- It's the difference between having a conversation and running a vacuum cleaner
- The Universal emits a soft soothing sound that fades into the background
Replacing Louder / Larger Systems
- Tired of depending 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
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
