Features & Compatibility
One of the greatest benefits of MrCool’s Easy Pro DIY ductless mini splits is the features that eliminate common problems and annoyances. Safety measures alert you when issues are present. Ease-of-use functions autonomously handle tasks to optimize your comfort with every cycle. Here are some of our favorite standard features that make a big difference:
- Leakage Detection: The display on the air handler will show an error code in the event that the refrigerant sensor detects a leak in the line.
- Gold Fin Condenser: Gold Fin protections provide corrosion resistance, allowing the outdoor unit to withstand harsh weather and environmental conditions.
- Auto-Restart: When power is lost unexpectedly, all previously chosen settings will be remembered and enacted when power is restored, and the unit automatically powers on.
- Louver Angle Memory: The air handler louver position and angle will automatically restore their prior position when powered on.

Control in the Palm of Your Hand
The MrCool Easy Pro DIY ductless split system comes with a remote control that lets you adjust your settings from anywhere in the room, but that’s not where your control options end:
- The Follow Me* feature automatically adjusts the air handler as needed to optimize temperatures in the area around the remote control.
- Timer functionality allows you to preset a specific run-time for the system before having it automatically power down.
- The smartphone app can access your Easy Pro DIY system from anywhere in the world with a cell signal, allowing you to adapt and monitor its status while you’re out and about.
- The Smart HVAC Controller directly integrates smart helpers like Google Assistant and Amazon’s Alexa with the MrCool Easy Pro DIY units, giving you the ability to adapt your settings using voice commands with your preferred virtual assistant.

Pre-Charged Line Set
MrCool has been putting the power of DIY installation into the hands of homeowners for years. Thanks to the innovation of MrCool’s pre-charged DIY Quick Connect line sets, there’s no need for specialized tools like vacuum pumps or manifold gauges during the setup process. Without the need to directly handle refrigerant, you won’t need to call in a professional. The pre-charged line sets are factory-sealed, removing the task of manual charging from the setup. The use of Quick Connect technology ensures a secure, leak-proof seal without any tools.
MrCool Easy Pro DIY ductless mini split heat pumps come with an 11.5” line set standard, but there are additional lengths of line set that range from 16’ to 50’ that you can purchase. If none of the standard sizes suit your needs, you can combine two standard line sets using a Quick Connect Coupler to create a custom length of line set to best suit your needs! There are two sizes of couplers to choose from, depending on the size of the Easy Pro DIY system:
Notable Specs
We’ll go over some of the more impressive factors that make the Easy Pro DIY mini splits stand out, but first, let me mention something I find crucial for home HVAC solutions: sound levels. MrCool emphasizes the Easy Pro DIY’s quiet operation, but what does “quiet” mean?
- Outdoor units range in decibel level from 54 to 61 dB(A)
- Indoor units range in decibel level from 17.5 to 51.5 dB(A)
Outdoor units consistently run at a higher sound level, but that makes sense when you think about the amount of insulation and other factors that eliminate sound between an outdoor condenser and the comfort of your couch. Think about it this way: the average vacuum cleaner sits at around 70 decibels. A noise that’s 60 decibels is roughly half as loud, even before getting filtered through walls and drowned out by other sounds.
Indoor units have less to eliminate their sound, so having hardware that operates quietly is paramount for well-rounded comfort. Sound levels decrease on lower settings and increase as the system works harder. Even with the largest model on its highest setting hitting sound levels just about 50 decibels, roughly one-fourth as loud as a vacuum cleaner, you’ll be shocked to find how little you hear your air handler when it’s running.

Inverter Technology
Many MrCool products advertise using inverter technology, but what does that really mean? Inverter-driven systems use variable-speed motors to supply only as much power as a system needs to maintain temperatures closer to your set-point. But what does this mean for you in application? It means temperatures stay closer to your preference throughout the day without running up a high energy bill. In fact, inverter systems can reduce energy consumption by 30% to 50% compared to traditional equivalents.
R-454B Refrigerant
MrCool’s Easy Pro DIY ductless mini splits use R-454B refrigerant, an eco-friendly and energy-efficient choice. Unlike older refrigerants like R-22 and R-410A, R-454B offers a drastically lower GWP (Global Warming Potential) and zero ODP (Ozone Depletion Potential). R-454B refrigerant is a more flammable material than R-410A. As such, it requires proper handling and storage for safe use.

Easy Pro Warranty
Performance is only one part of the equation when looking for a worthwhile climate control solution. Choosing a system solely for its efficiency ratings or size is tempting, but finding a fit for your home with a warranty that gives you peace of mind is worth the effort. As mentioned above, the MrCool Easy Pro DIY units come backed by a standard limited warranty that offers 3-year coverage on parts and 5-year coverage on the compressor.
If that wasn’t already impressive enough, the Easy Pro DIY systems are even eligible for the MrCool Care Program! Between the included warranty and the option to extend compressor coverage, the MrCool Easy Pro DIYs instill confidence that their performance will last for years to come. You can learn more about the specifics of what’s covered by the warranty in the MrCool Easy Pro Series Limited Warranty document.
