Pros and cons of buying a MR Cool heat pump
The good
The bad
How much do they cost?
When it comes to the cost of HVAC installations, the price can vary quite a bit based on several factors, including the model, size, and where you are located in the US.
Customers often find the pricing a bit of a maze, so let's simplify it.
Pricing by Model & Size
Let's break down the pricing by different BTU (British Thermal Unit) capacities, which determine the size of the area the unit can effectively heat or cool.
Here's a simplified table to give you an idea:
MR Cool Model Size | Approximate Price Range |
|---|---|
12k BTU | $1,500 - $3,000 |
24k BTU | $2,500 - $4,500 |
36k BTU | $3,500 - $6,000 |
Remember that these prices are estimates and can vary based on the model's specific features and the installation's complexity.
Cost variation across US States

The cost can also vary based on your location in the United States.
For instance, installation costs in New York or California are generally higher than in states like Texas or Florida.
This is due to differences in labor costs, living expenses, and even the complexity of installations due to building structures.
In my career, I've seen variations as much as 20-30% in installation costs between different states (which is why many opt for the DIY MRCOOL).
Remember, these are ballpark figures to give you a sense of what to expect.
It's always a good idea to get a detailed quote from a local HVAC professional for the most accurate pricing.

What makes MR Cool heat pumps stand out?
In the world of heating and cooling, MR COOL has managed to carve out a unique place for itself.
These systems have revolutionized the DIY heat pump market, offering a level of efficiency and ease of use that's hard to beat.
Let's dive into what makes them stand out:
High-efficient energy saving DC fan motor
I remember the first time I installed a MRCOOL system. The high-efficient energy-saving DC fan motor was a game-changer.
It's not just the efficiency of the motor but also the compressor technology that makes these units so energy-efficient.
They're designed to provide maximum cooling and heating while keeping energy bills low.
This efficiency is such a helpful feature, especially in extreme weather conditions. That’s why it’s one of my favorite features of this HVAC system.
Multi-position installation options
What's really impressive about these units is their multi-position installation options.
Whether you're putting the indoor unit or the outdoor unit, the flexibility is remarkable.
The air handler can fit in various positions, which means you can simply choose the most convenient spot, like the floor.
Yes, you can buy units that fit on the ceiling, wall and even the floor.
This flexibility in installation makes MRCOOL units a favorite among DIY enthusiasts and professionals alike. However, I always recommend hiring a professional.
Special fire proof electrical box design
Safety is paramount in HVAC systems, and MR COOL takes it seriously. Their fire-proof electrical box design is a testament to this.
It's not just about preventing accidents; it's about providing peace of mind.
The safety and support this feature offers can't be overstated, especially when you're installing the system in a family home.
R410A factory pre-charged
The R410A factory pre-charged feature is a real-time-saver. Typically, charging the refrigerant lines can be a hassle, but with MR COOL's pre-charged lines, it's a breeze.
This feature simplifies the installation process, but I still recommend hiring an HVAC professional installer.
If the lines need to be longer than anticipated, then adding more lines or running a completely new line set will need to be calculated for proper charge. Pressures, proper leveled installation, and operation will still need to be checked.
How energy efficient are they?
Not all MR COOL heat pumps are Energy Star certified, which is a seal of how energy efficient the products are.
However, they are often designed with energy efficiency in mind. This is particularly important when it comes to both cooling and heating your home.
The key to understanding their efficiency is the SEER (Seasonal Energy Efficiency Ratio) rating: the higher the SEER, the more energy efficient the unit is.
This means you'll enjoy more efficient cooling during the summer and effective heating in the winter, all while maintaining an optimal indoor temperature.
In my time advising on HVAC systems, I've seen how a higher SEER rating can translate to significant energy savings over time, making it a critical factor for many homeowners.
So, while only some MR COOL heat pumps might be Energy Star certified, like the DIY 4th Generation, their high SEER ratings often indicate a strong focus on energy efficiency, beneficial for both your comfort and your energy bills year-round.
How do the compressors perform?
The compressors in MR COOL systems, particularly in their ductless mini splits, are known for high performance and efficiency.
These compressors operate more quietly and efficiently than many traditional units, adeptly running to maintain the desired temperature.
They can gauge room conditions and can flip between cooling and heating modes with ease, ensuring comfort in every season.
In my experience, MR COOL compressors stand out for their ability to provide consistent temperature control without excessive energy consumption.
This makes them an excellent choice for those looking to balance performance with energy efficiency, whether for residential or commercial applications.
Warranty analysis – How does it stack up?
With Mr. Cool, like many heat pumps and AC manufacturers (like Carrier and Trane), the warranty coverage can vary significantly depending on the product.
It's not a one-size-fits-all scenario. For instance, their ductless mini split systems have a different warranty length than their more affordable units.
For instance, models like the 4th Generation DIY Units often have a limited lifetime warranty, while the Universal series has a 10-year limited warranty.
Remember, regardless of the product, registration is usually necessary to take full advantage of the warranty.
Of course, the conditions and restrictions of the warranty can vary with different models. Always check the specifics for the model you're interested in.
Comparing these details with the competition is also wise, as it gives you a sense of the value you're getting for your investment.

Next, you also need to choose a reliable technician. Selecting a competent HVAC technician or installer is the secret to ensuring a hassle-free installation.
I suggest starting with recommendations from friends or neighbors who've recently gone through the process.
Don't overlook the power of online reviews, either. Lastly, it's vital to check that the professionals are licensed and insured.
DIY install option
One unique aspect of Mr. Cool is the DIY option they offer. This is particularly appealing for handy homeowners looking to save and lower installation costs.
Cool's systems are designed with the DIY enthusiast in mind, offering a more straightforward installation process than traditional HVAC systems.
However, it's important to assess your skills realistically and be prepared with the right tools.

Anonymous
Installed unit as per instructions yet unit only blows room temp air, no heat no air conditioning. I have emailed, called, and left messages without response. Don't know what else to do.
- Filed a complaint with Better Business Bureau
Diving into the reviews, I noticed a pattern. Many of the bad reviews come from those who went the DIY installation route.
MR Cool is big on DIY, but if you're not technical, this can be a stumbling block. It seems many issues are installation-related, not with the units themselves.
So, if you're leaning towards a DIY setup with MR Cool, make sure you've got the skills for it.
