9 Best Mini Split Heat Pumps For Cold Weather Of 2024!

If you are looking for a mini-split heat pump that offers it all, more efficient operation, smart adjustable temperature controls, and simple installation, I would have to recommend the Pioneer WYS012G-19 above all.

How I Picked
Temperature Resistance

From experience, I knew that a lot of heat pump designs were simply ineffective in colder temperatures. Therefore, I focused most of my search on finding a model better suited for colder temperatures.

Energy Savings

With the technology available today, it only makes sense to choose a heat pump that will eventually pay for itself in energy savings.

Installation Configurations

I not only wanted a mini-split that I could install myself, but I also wanted one that I could mount off the ground, out of the snow to prevent freezing.

Refrigerant Operation

With R-22 being phased out, it only made sense to me to opt for the newer refrigerant. Opting for a model that operated by using R-410A Freon only made sense.

Top Pick
Pioneer Air Conditioner WYS012G-20 Wall Mount Ductless Inverter+ Mini Split Heat Pump, 12000 BTU-208/230V

12,000 BTUs at 208/230 volts offer raw operational efficiency in a complete package. Durable heating and cooling system that saves as good as it looks!

Check Price on Amazon

There are several reasons that the Pioneer Air Conditioner WYS012G-19 was my top pick.

However, the biggest thing was the installation aspect. Pioneer did an excellent job of eliminating the guesswork.

I didn’t need to guess about the copper and wiring configurations. Everything came properly sized in the package.

Choosing the wrong copper tubing or wiring would not only make installation impossible but could also cause operational inefficiencies.

Pioneer eliminates all the guesswork and includes everything needed for the entire installation.

Along with this, the WYS012G-19 is a heat pump, that offers both efficient heating and cooling.

Speaking of efficient operation, the manufacturer includes a certificate of efficiency along with the purchase just to back their energy-savings claims.

The entire package is not only convenient but it is attractively designed with the indoor unit including a beautiful flat panel and LED display.

The automatic swing air louvers will effectively discharge air throughout the room, while the permanent washable air filters make maintenance easier than ever.

The indoor multi-speed fan motor not only offers operational efficiency, but it is whisper quiet.

The outdoor unit also includes a variable multi-speed DC compressor to further add to the overall efficiency.

The outdoor unit is comprised of extremely durable galvanized metal with electrostatic paint.

Simply put, it’ll easily handle the harshest weather conditions and look good while doing so.

Budget Pick

More than enough for a big bedroom or sunroom.

Along with the air handler and condenser, the package includes 16 feet of pre-flared copper lines, remote control, R-410A, and 16 feet of control voltage wiring.

That’s everything but the line voltage needed for the condensing unit, and the pre-flared copper lines eliminate the need to solder, offering a 100% guaranteed leak-free connection.

The R-410A Freon ensures that you have the newest refrigerant, reducing the potential cost of leaks in the future.

The unit can be installed anywhere in the home that the copper lines will reach. Of course, you can add to them, but that’ll require more copper.

The sleek, beautiful indoor unit mounts on an interior wall and includes its very own mounting brackets and mounting anchors.

Although Senville is an unheard-of HVAC manufacturer, you get 5 years warranty with the initial purchase.

Anything goes wrong in the first 5 years all you need to do is contact the manufacturer and they’ll handle the issue.

The 4-in-1 design offers an air conditioner, heat pump heat, dehumidification, and fan circulation.

The fan also comes fully equipped with a powerful turbo mode for more circulation of indoor air.

Senville only uses the latest technology and engineering to deliver an efficient and powerful heating and cooling system.

Washable filters not only save money but make maintenance twice as easy.

What Has to Be Considered When Pick a Mini-Split Heat Pump for Cold Weather?

Choosing an entire heat pump system designed to specifically handle cold weather is entirely different than shopping for a thermostat or humidifier.

However, that doesn’t mean much of the process doesn’t go hand-in-hand.

It honestly comes down to eliminating options and features until you are left with what you need.

Since you know you need a heat pump that already puts you a step ahead.

Knowing that it needs to operate efficiently in colder temps puts you even further ahead.

From there, it is basically considering the size of the unit your need, the installation parameters, and the features that most matter to you and your family.

Measure the length and width of the room where you are installing the unit. Multiply them together to calculate square footage.

12,000 BTU or a 1-ton unit can handle 600 square feet. 18,000 BTU or a 1.5-ton unit can handle

900 square feet. 24,000 BTU or a 2-ton unit can handle 1,200 square feet.

Using this simple guideline along with some of the above-mentioned features should put you on the path to narrowing your options.

Considering a reliable brand along with durable outdoor models that can be mounted above the snow level will only further narrow your options.

Before you know it, you will have narrowed the playing field so that you only have a few options to choose from.
