Energy Saving i-See Sensor

Mitsubishi has further improved the efficiency of their heat pumps by incorporating their unique ‘i-See sensor’ technology.

It uses infrared technology to sense occupancy in a room and adjust the heat pump operation accordingly.

The ‘i-See’ technology is particularly effective for zonal temperature control, making them my go-to option for large homes with diverse heating and cooling needs.

Advanced Air Filtration

Mitsubishi heat pumps use advanced filtration systems that offer allergen and plasma filtration alongside standard contaminant filtration.[3]

Advanced air filtration helps protect the heat pump from damage and improves indoor air quality. I recommend them for homeowners with allergies or respiratory conditions.

Whisper Quiet Operation

Mitsubishi heat pumps are quieter than competitors because of their design and build quality.

Most units have sound insulation to dampen operation noise and an advanced fan design that helps the blades move smoothly.

Mitsubishi heat pumps typically run at 30-50 decibels (less than a quiet conversation), making them ideal for smaller homes or residents sensitive to noise.

Smart Controls and Connectivity

Mitsubishi heat pump models almost always include remote control options (usually over Wi-Fi).

It makes the heat pump operation and monitoring more straightforward and provides more flexibility than other brands.

TL;DR: There are two important characteristics that are hallmark of Mitsubishi heat pumps: reliability and efficiency. 

How Is The Energy Efficiency?

Mitsubishi creates some of the most energy-efficient heat pump systems, with greater energy efficiency than other brands in the same price range.

The average SEER rating is over 20, while other brands are under 15.[5]

The higher efficiency is a focus for the Mitsubishi brand and is down to the responsive technology and smooth operation.

Mitsubishi heating and cooling systems can lead to significant energy savings compared to traditional heating systems.

I recommend the brand to anyone looking to lower their running costs.
