Our Experience with the MRCOOL Ductless Mini Split AC Heat Pump
I've personally installed the MRCOOL DIY 12k BTU system, and it's a game-changer for budget-friendly, high-efficiency cooling. The 5th-generation design feels modern and reliable, with the smart features like the Follow Me function and smartphone app making temperature control effortless. I liked how the unit automatically restarts after power outages, which was a lifesaver during a summer blackout.The pre-charged line set and DIYPro armored cable simplified the process, though I still needed some basic tools and a bit of patience. the energy Star certification and 23.5 SEER2 rating also impressed me-it runs quieter and uses less electricity than my old system.
The Gold Fin condenser is a standout, especially in humid or coastal areas, as it resists corrosion and lasts longer. I used it in a sunroom and a garage, and the 550 sq ft coverage worked well. The digital assistant compatibility with Amazon Alexa and Google Assistant added convenience, letting me adjust settings with voice commands. Though, I noticed the installation instructions could be more detailed for first-timers, and the 12k BTU model isn't the most powerful for larger spaces. Still, the 1-year labour warranty by IWAE gives peace of mind, and the system's performance during extreme temperatures (from -4°F to 122°F) was solid.
The MRCOOL DIY offers a balance of performance and affordability, but it's not without its drawbacks. While the R-454B refrigerant is eco-friendly and efficient, the lack of a replacement warranty for parts might be a concern. The compact indoor unit is easy to mount, but the outdoor unit's weight (83 lbs) makes moving it a bit of a chore. it's a great option for DIY enthusiasts who want smart, energy-efficient cooling without professional help. If you're unsure about installation, hiring a licensed electrician is recommended.
