HVAC

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. The Mitsubishi FH Series Heat Pumps fall short of the mark in key performance categories above as compared to Fujitsu.

Overall Winner: Fujitsu
