What is Mitsubishi?
Mitsubishi is recognized globally as a leader in advanced, ductless heating and cooling technology.
Unlike many standard systems, Mitsubishi is often associated with high-SEER (Seasonal Energy Efficiency Ratio) ratings, which translates directly to lower utility bills and superior energy savings. Their systems are particularly popular for their ability to provide year-round comfort, as many models feature Hyper-Heat technology that allows the unit to continue efficiently heating a space even in extremely cold climates where other heat pumps fail. This makes Mitsubishi an ideal choice for homeowners who require reliable, quiet, and customizable HVAC solutions.
Mitsubishi's core strength lies in its expansive range of indoor units, including wall-mounted, floor-standing, ducted, and ceiling cassette options, which allows for true customization and zoning. Whether you are cooling a single room, adding comfort to a garage, or designing a multi-zone system for an entire home, Mitsubishi provides a flexible solution that integrates seamlessly. By choosing Mitsubishi from South Mini Splits, customers are investing in industry-leading reliability, cutting-edge inverter technology for precise temperature control, and a system designed for decades of quiet, efficient operation.

When to "Size Up"
If your ceilings are 10 feet or higher, you are cooling a larger volume of air. We recommend increasing your BTU choice by 20%.
For older homes or buildings with single-pane windows, opt for the next size up to ensure the unit can maintain the set temperature.
Appliances generate significant heat. If the unit is for a kitchen, add 4,000 BTUs to your square footage calculation.
Rooms with large south-facing windows or "sunrooms" act like greenhouses. Increase your BTU capacity by 10-15%
If the area regularly hosts more than two people (like a conference room or classroom), add 600 BTUs per additional person..
FAQs/Frequently Asked Questions
Q: Is a licensed HVAC contractor required to install a Mitsubishi system for the warranty to be valid?
A: Yes. For all non-DIY systems, the manufacturer's limited warranty is typically valid only when the system is installed by a state-certified or licensed HVAC contractor in accordance with all local codes and installation instructions.
Q: What is Mitsubishi's Hyper-Heat technology and how does it benefit my home?
A: Hyper-Heat is Mitsubishi's specialized heat pump technology that allows the unit to continue heating efficiently even when outdoor temperatures drop significantly below freezing (often down to -13°F or lower), providing reliable heat without needing supplemental electric resistance.
Q: How do Mitsubishi mini-splits compare in noise level to traditional AC systems?
A: Mitsubishi mini-split systems are renowned for being exceptionally quiet. Indoor units often operate at noise levels as low as 19-25 decibels, which is quieter than a whisper, providing silent comfort compared to loud, traditional central air conditioners.
Q: Can Mitsubishi multi-zone systems heat and cool different rooms to different temperatures simultaneously?
A: Yes, multi-zone systems are designed to allow each indoor unit (head) to be controlled independently. This means one zone can be set to cooling while another is set to heating, providing maximum comfort and efficiency across the home.
Q: Are Mitsubishi mini-split systems eligible for state or federal energy efficiency rebates?
A: Many high-SEER and Energy Star-rated Mitsubishi models are eligible for various federal tax credits, state-level rebates, and local utility incentives. We recommend checking the system's specific AHRI rating with your local utility provider for current eligibility.
