M Series Vs P Series Mitsubishi Heat Pump (In-Depth Comparison)

The Mitsubishi heat pump M and P series are the most often used models worldwide. However, the vast majority of installations use one more than the other Mitsubishi models that are available.

Therefore, it’s logical to anticipate a few unique features and a well-known brand’s high-efficiency heating system that set this model apart from others on the market.

Opting for the Mitsubishi heat pump M series or P series can be overwhelming. However, if you want to update your present heat pump or install a new one in your new house, you should look at Mitsubishi’s P series rather than the M series.

What Is Mitsubishi M Series?

Mitsubishi Heat Pump M Series Vs. P Series

The Mitsubishi M Series offers an adaptable and inexpensive heating and air conditioning method for areas ranging in size from retail units and small offices to houses and other residential settings.

These rooms can be cooled or heated according to the user’s needs. The M Series is available in many configurations, including versions that may be on the wall or the floor.

In addition to its excellent efficiency ratings, Mitsubishi’s M-Series split-ductless heat pump was known for its sleek design and affordability. 

The M-Series offers stable economic performance in energy use, with sound levels as low as 20 dB. Additionally, it effectively heats zones.

The inverter-driven compressor and the zone control contribute to maintaining comfortable temperatures while reducing overall energy use. 

The machine has washable anti-allergen filters created from natural materials. These filters enhance the air quality and ease you can access them to ensure that the machine requires very little maintenance.

What Is Mitsubishi P Series?

The Mitsubishi Series comprises Mini-split air conditioners and heat pumps that provide the advantage of being non-traditional in addition to the benefits of efficiency and dependability for use in commercial and industrial settings, respectively.

They are ductless systems designed to function flawlessly in the chilly environment of Canada.

Every unit has a low-ambient cooling mode built in as a standard feature, enabling the devices to reach temperatures as low as -18 degrees Fahrenheit.

Systems that need cooling even when the outside average temperature is as low as -40 degrees Celsius may use a specialized extreme low-ambient cooling solution that is also available (ultra-low ambient kit required).

The P-Series from Mitsubishi is a strong line of systems that can handle the most demanding environments, including office buildings, server rooms, storage rooms, eateries, elevator rooms, and retail establishments.

With the most up-to-date technology on the market, Mitsubishi’s ductless cooling units, the P Series, will offer you decades of reliable cooling while paying for themselves in only a few short years via the savings on energy alone.

Mitsubishi M Series And P Series: Which Is Better?

This particular product and model will have a few distinctive characteristics that set it apart from other brands currently on the market, given that it is a highly energy-effective heating system that originates from a recognized business.

The flexibility with that you can configure the devices in the Mitsubishi P series to meet your requirements is one of the series’ most appealing qualities.

For example, you can select one of many indoor units, such as the tower unit, a four-way ceiling cassette, or a ceiling suspended unit.

Each possesses a few characteristics that make it particularly well suited for specific zones, whether you need to heat or cool them.

In addition, these indoor units have a few characteristics, including low noise levels during operation, straightforward maintenance procedures, and high-performance levels.

Structural systems are a defining feature of the Mitsubishi M and P series designs.

The construction of the P series Mitsubishi is with industrial-grade materials, which are meant to last longer and are more resistant to severe weather’s effects.

Because of this, the P series is a model that is quite popular in the warmer sections of the United States, such as Miami. In addition, it is owned both by homes and business owners.

When faced with these conditions, it is in the consumer’s best interest to invest more money upfront for a reputable brand name of air conditioning equipment that will perform adequately. 

A good reputation precedes heating systems manufactured by Mitsubishi. The best part is that most air conditioning repair specialists do routine maintenance and have replacement parts on hand in case you need them.

Mitsubishi M Series Vs. P Series: Price Comparison

Both models are within the same price range; however, the Mitsubishi P series is much more costly.

The typical cost of the Mitsubishi P series without installations is around $5,000, while the average cost of the Mitsubishi M series is approximately $3,000. Neither of these prices includes the cost of delivery and installation.

Various brands are available, including the Mitsubishi P series and the Mitsubishi M series, which are affordable depending on your budget and preferences.

Even though there is a wide variety of other manufacturers and models available, homeowners in Miami seem to like this specific brand and model the most.

However, you should consider the size of the heat pump. You’ll need a lot of weight to get the most out of the machine.

If you purchase a device that is too small, it will continue to work to maintain a specific temperature.

A larger engine will consume more power and operate for a shorter period, leading to earlier wear and tear on the internal components. However, SEER and HSPF scores are also important.

You may need more than just high ratings. The delicate balancing act between size, effectiveness, and cost is critical. No matter how efficient a unit is, it doesn’t always work best for your house.

Additionally, noise pollution is another issue. Many luxury manufacturers offer noise reduction solutions (covers, blankets, insulation, etc.), but they come at a price.

A machine that isn’t too noisy (anything less than 65 dB, for example) yet doesn’t break the bank is what you need.

Moreover, it is necessary to consider the actual cost and the warranty period. Technology, features, and advancements raise the price per unit.

Some are essential, while others are optional. Therefore, finding a suitable model at the right price is critical.

Differences Between The Mitsubishi M Series And P Series

The primary distinction between the Mitsubishi M series and the Mitsubishi P series is that the construction of the P series has a greater emphasis on commercial application and longer duration.

This more extensive system comes at a more excellent financial investment than the more compact M series.

Depending on the project’s requirements, these two models may be used for public or private reasons.

For example, it may not be necessary for all companies to have a heating system as strong as the Mitsubishi P series, in which case the M series would be more than enough to maintain a comfortable temperature in the workplace.

Because of this, some homeowners may want the more durable and robust model to provide a constant supply of fresh, cold air within their houses. 

Although the cost difference between the Mitsubishi M series and the P series is on the lower end of the spectrum for the cheaper model, the Mitsubishi P series is a much more versatile alternative that you can use for residential and commercial installations.

Wall-mounted interior units, units that suspend from the ceiling, and ducted interior units are all options for installing any model’s interior.

Because it comes in such a wide range of BTU loads, the Mitsubishi P series is a fantastic option for both compact and expansive living quarters.

The concept that you can complete the installation quickly and easily in a condensed period is one of the primary reasons why such a large number of people choose this particular brand.

In most cases, certified experts can complete the installation in a single day without requiring you to make significant adjustments to how you usually go about your day.

The installation process may take a little bit longer for more extensive installations that include a more significant number of outdoor and interior units.

Still, it does not take nearly as much time as it does for a few other brands now on the market.
