Features of the MSZ-GS Large Capacity Wall-Mounted Unit
The MSZ-GS Large Capacity Wall-Mounted Indoor Unit comes with great features, specially designed to improve the efficiency of the unit while also improving the comfort of your home.
Dual Barrier Coating
The main interior parts of this wall-mounted indoor unit — the air duct/vane, coil, and fan — have a dual barrier coating. The coating protects these components from dirt and grime, helping the system to run more efficiently.
When you engage Powerful Mode, the MSZ-GS Large Capacity Wall-Mounted Indoor Unit very rapidly heats or cools your area. This feature automatically shuts off after a certain amount of time to safeguard efficiency.
The Econo Cool feature uses special airflow technology to reduce the temperature setting by a few degrees without changing how the room feels. This keeps you comfortable while saving energy.
Similar to an oscillating fan, the swing fan moves the air around the room. Whether you’re heating or cooling, it ensures comfort in every single corner of your room.
Additional Specifications of the MSZ-GS
The MSZ-GS Large Capacity Wall-Mounted Indoor Unit has the following specifications.
Capacity of 30,000 to 36,000 BTU/H
This capacity allows this unit to cool spaces ranging from 1500 to 2500 square feet and larger. Note the exact cooling area may vary depending on ceiling height, wall insulation, and other factors. We’ll help you pick the perfect capacity for your home.
Sound as low as 32 dB(A)
While operating, this large-capacity wall-mounted unit runs at a sound level as low as 32 dB(A). This is quieter than most refrigerators and about the noise level of a whispered conversation.
SEER up to 18.10
With a Seasonal Energy Efficiency Ratio (SEER) of up to 18.1, this unit promises to run about 28% more efficiently than similar systems with the same capacity. SEER refers to an air conditioner’s cooling output divided by the energy it uses in watt-hours through a cooling season.
HSPF up to 10.0
Heating Seasonal Performance Factor (HSPF) is a heating efficiency rating applied to heat pumps, and efficient models fall between an eight and 10 on this scale.
COP up to 2.86
The coefficient of performance (COP) measures the cooling or heating power of a heat pump or air conditioner compared to the amount of energy it uses.
ENERGY STAR®: No
Although this large-capacity unit meets Energy Star standards in several categories. It doesn’t have the overall ratings to earn Energy Star certification.
