Ductless Decisions – Fujitsu vs Mitsubishi Mini Split Heat Pump Review
We compare and contrast the top models for Fujitsu (ASU9RLS3) and Mitsubishi (MSZ-FH09NA) utilizing four key product categories:
Warranty
Operating Temperatures
SEER Rating
Heating/Cooling BTUs
Warranty
The Fujitsu ASU9RLS3 has a standard 10 year warranty, but because Endless Energy is a highly trained Elite Fujitsu Contractor, our installations include an industry leading 12 year warranty!
The Mitsubishi MSZ-FH09NA boasts a 7 year warranty – five years less than an Endless Energy Installed Fujitsu unit.
Winner: Fujitsu
Operating Temperatures
The Fujitsu ASU9RLS3 operates efficiently down to as low as -15˚F because of the anti-freeze heater in the outdoor part of the unit (Fujitsu-general.com) and will still generate heat at temperatures below -15.
The Mitsubishi MSZ-FH family operates down to -13˚F, but loses efficiency as temperatures decrease below freezing. Operating vs. Operating Efficiently matters, especially in colder Northeast climates where every degree counts (Mitsubishipro.com).
Winner: Fujitsu
Seasonal Energy Efficiency Ratio (SEER)
The Fujitsu ASU9RLS3 is the industry’s top energy-saving performance and high heating capacity in the US with the highest SEER rating possible to-date: 33 (Fujitsu-general.com)
The Mitsubishi MSZ-FH09NA/MUZ-FH09NA comes in short at 30.5 SEER – Impressive, but not the top SEER Rating (Mitsubishipro.com)
Winner: Fujitsu
Heating/Cooling Btus (British Thermal Unit)
The Fujitsu ASU9RLS3 has 12,000 Btu/h heating, 9,000 Btu/h cooling (Fujitsu)
The Mitsubishi MSZ-FH09NA has 10,900 Btu/h heating and 2,800 to 9,000 Btu/h cooling (Mitsubishi)
Winner: Fujitsu
Summary
The Fujitsu RLS3 Series Heat Pumps are the industry’s top energy-saving family of heat pumps. Although still more energy efficient than traditional methods of heating and cooling, the Mitsubishi FH Series Heat Pumps fall short of the mark in key performance categories above as compared to Fujitsu.
Endless Energy carries and installs both Fujitsu and Mitsubishi systems, however we typically recommend Fujitsu to our customers as they have the superior value and efficiency. If you’re interested in learning more about top tier heating and cooling, contact us today to set up a free consultation!
