MRCOOL Mini Split Systems: HSPF Ratings and Noise Levels Explained for Every Model

In this detailed guide, we break down the HSPF (Heating Seasonal Performance Factor) ratings and noise levels for each MRCOOL mini split system, including the EZPRO, 4th Generation DIY, and Advantage Series. Understanding these metrics is crucial when selecting the right system for your home.

  • HSPF ratings indicate the system’s heating efficiency, with higher numbers reflecting better performance and lower energy consumption.
  • Noise levels are important for comfort, particularly for indoor units, and are measured in decibels (dB).

This guide allows you to compare various MRCOOL systems to find the right balance between energy efficiency and quiet operation, helping you make an informed decision based on your home’s specific heating and cooling needs. Each series is broken down by model size, so you can quickly reference the unit that fits your installation requirements.
