Mitsubishi heat pump review – My honest opinion
Pros and cons of buying a Mitsubishi heat pump
I have used Mitsubishi heat pumps for over a decade and recommended them to homeowners and colleagues.
There is a lot to like but a few drawbacks, so here's a summary of their strengths and weaknesses:
The good
The bad
How much do they cost?
Mitsubishi heat pump models can cost anywhere from $700-$5000+, depending on the size, coverage, and features.
That’s just for the units themselves, not the installation costs.
The installation costs will vary massively depending on the location, labor rates, and specific installation costs.
Residential or light commercial installation will typically cost $1000-$5000, but for industrial fitting, the costs can be over $10,000.
Pricing by model & size
Category | Average Price For Unit | Expected Features | Models / Series |
|---|---|---|---|
High-End | $3000-$8000 | ||
Mid-Range | $2000-$5000 | ||
Low-End | $750-$2000 |
Cost variation across United States
Mitsubishi heat pump systems are sold through authorized dealers and distributors, and the costs vary based on:
Typically, States on the North East and West Coast (like New York, Massachusetts, and California) have higher living costs, so you’ll pay more for the unit and labor.
Heat pumps are more useful in States with variable climates, so there may be more demand in North Carolina, New Jersey, Virginia, Tennessee, Missouri, Ohio, Delaware, Pennsylvania, and Maryland - increasing the unit price.
I recommend looking in your region to get an accurate idea of unit price and installation costs before you buy your heat pump.

What makes Mitsubishi heat pumps unique?
More environmentally friendly R32 refrigerant
Mitsubishi heat pumps typically use R32 refrigerant with a lower global warming potential (GWP) than other refrigerant types.
R32 is also more efficient, allowing Mitsubishi heat pumps to have a higher heating seasonal performance factor than other brands while being more environmentally friendly.
Energy-efficient EcoCore inverter technology
Traditional HVAC systems use fixed-speed compressors, but Mitsubishi heat pumps use EcoCore inverter technology that operates at variable speeds and power outputs.
The technology allows Mitsubishi heat pumps to be more responsive, reduce temperature fluctuations, and improve overall efficiency by only running as and when needed.
Dual barrier coating
Mitsubishi uses dual barrier coating to enhance the durability and efficiency of the heat exchanger within their heat pumps.
It keeps out more dirt, oil, and other contaminants than other heat pump brands, improving the heat transfer speed and increasing the heat pump lifespan.
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.
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.
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.
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.
How do the compressors perform?
Mitsubishi compressors perform exceptionally, and it’s probably the stand-out feature of their heat pump system.
The inverter-driven compressors operate at variable speeds and use hyper-heating technology to generate heat in extreme cold.
They’re durable, reliable, and effective - everything you want from your heat pump system and far exceed the competition.
Warranty analysis – How does it stack up?
Mitsubishi heat pumps have solid warranty coverage.
Most Mitsubishi heat pumps have 5-12 years of coverage (depending on the make and model), which is far higher than the standard warranty for heat pumps (2-5 years).
For your warranty to be valid, you must register it with Mitsubishi customer service within three months of the heat pump system installation.
The Mitsubishi warranty covers any construction or material defects and any electrical faults.
However, the guarantee may vary depending on who has supplied and fitted it.
I recommend using one of their pre-approved contractors to ensure your warranty is valid.
