    Heating Power: 12,000 BTU
    Cooling Power: 12,000 BTU
    SEER Rating: 20
    Lowest Air Temperature Allowed: -13º F

    The Daikin Aurora is a fantastic miniature ductless split heat pump system. It provides a well-rounded suite of features that cover all areas.

That means you don’t have to worry about this unit in most climates. The only drawback is that it requires frequent defrosting in certain conditions. The condenser freezes up but will quickly thaw.

    When it comes to power, efficiency, and cold weather durability, the Daikin Aurora 12k BTU unit is simply one of the best that money can buy.

    Pros
    • Good cooling power
    • Operates in extreme cold

    4. MAXWELL Daikin Aurora Mini-Split Heat Pump System — Best Small Size

    MAXWELL Daikin Aurora Mini-Split Heat Pump System

    Power Supply: 230V (DC)
    Heating Power: 9,000 BTU
    Cooling Power: 9,000 BTU
    SEER Rating: 20
    Lowest Air Temperature Allowed: -13º F

    The Daikin Aurora 12k BTU Mini Heat Pump system is the perfect small-sized heat pump. This unit is great for cabins or other small spaces that are consistently cold. It can function at temperatures as low as -13º F, meaning it will withstand all but the most extreme weather. The unit is not very large, it is easy to install, and it is not heavy. It even comes with a comprehensive 12-year warranty from the manufacturer, so you know it will last a good long while.

    The biggest downside is the small stature of this unit means it can only heat 350 square feet comfortably. It will not handle large spaces very well, and straining the system leads to frequent defrosting intervals. But if you are looking for a small heat pump, you can install it yourself. This is a great option.

    Pros
    • Compact
    • Lightweight
    • Efficient
    Cons
    • Small coverage
    • Frequent defrosting

    Heating Power: 9,800 BTU
    Cooling Power: 9,000
    SEER Rating: 22.5
    Lowest Air Temperature Allowed: 17º F

    If you are worried about energy efficiency ratings, this is a heat pump you should look into. This is the most efficient heat pump on this list. The SEER rating of 22.50 is the best by far.

But if you are someone who likes gadgets and likes to have everything integrated, then the DELLA model will be right for you.

    Pros
    • Lots of innovation
    • Smartphone compatible
    • Affordable

    Buyer’s Guide: How to Select the Best Heat Pumps For Cold Weather

    Different Types of Heat Pumps

    There are three different types of heat pumps available on the market. The three types of heat pumps are air-source, split-ductless, and geothermal. Knowing the difference between these three types is crucial for making a decision about what kind of heat pump is right for you.

    The most common type of heat pump is an air-source heat pump. These pumps are often installed by HVAC professionals and include an outdoor unit and an indoor air handler.

    The second most common type of heat pump is the split-ductless variety. These are the types of heat pumps you can buy and install on your own because they do not require ducts to be in place to function. These pumps often only heat one room or a small space.

    Lastly, there are geothermal heat pumps. These pumps use buried pipes to maintain constant ambient heat. Geothermal heat pumps are the least common because they require a lot of room and a lot of money. A typical geothermal system can cost up to $30,000 to install.

    Always Check The Temperature Ratings

    Heat pumps all have an official temperature rating. These numbers dictate what temperatures the system can run at while outside. Even if the temperature numbers are not readily available, they should be buried in the technical specifications. Always double-check the allowable temperature range before buying.

    We tried to put as many cold weather pumps on this list as possible, but if you are looking at heat pumps on your own, check the temperature range. You will be surprised to find that some of the units on the market have ranges that hardly dip below freezing. If you buy a system with a 15º F low and have to live through a sub-zero cold snap for a week, you will be very, very cold.

    What Is SEER?

    SEER stands for Seasonal Energy Efficiency Ratio. It is a metric used by the federal government to regulate the efficiency of air sources and split-ductless air systems. The higher the SEER rating, the more efficient the heat pump. A more efficient heat pump means less energy expended on heating and cooling the room. The minimum federal guidelines for heat pump SEER ratings is 14.

    Another energy efficiency rating you might come across while shopping for heat pumps is the Heating Seasonal Performance Factor (HSPF). This rating is less commonly used, but it also applies to these heat pumps. A good HSPF rating is actually more important for cold weather heat pumps than SEER, but the HSPF rating is harder to find than SEER.

    Consider The Noise

    Heat pumps can be noisy. Some product pages offer an average noise level in decibels, but many of them don’t. Some heat pumps are known to be extremely noisy. Since many of these products require an indoor wall-mounted air handler, the noise factor can be very important. You do not want to install a brand-new heat pump system next to your bed only to find out that the noise is going to keep you up all night. These are not quiet machines. Some of these units come with low noise modes for bedrooms, but not all of them do. Do not forget to think about the placement of your new system and the noise it can produce.

    Know Your Space

    Most of the heat pumps that you can buy and install yourself are split-ductless heat pumps. These pumps are often made to heat one single room and offer varying amounts of coverage. Before taking the plunge on a heat pump, it is best to know the space you are going to be installing it in. Is the room drafty? How big is the space? How hot/cold does it get normally? These are important questions to ask before jumping onto a fancy new product.

    One of the most common complaints that arise online is from people who installed undersized heat pumps and then complained that they do not heat and cool appropriately. It is no good to find a heat pump with great reviews only to realize it is made to heat 350 SF when you need to heat 700 SF. Even if the BTU numbers look good, if the air handler is not equipped to pump air into a larger space, it won’t heat efficiently.

    Know your space before you buy. It could save you a lot of time, money, and effort.

    The MAXWELL 12,000 BTU still offers the best overall value regarding price, efficiency, and reliability. However, Cooper & Hunter Hyper Heat Dual Zone is still a solid contender as the second pick and provides a significant amount of savings compared to the alternative.

    With this guide, choosing your next cold weather heat pump should be a breeze.

After all, heat in cold climates is important, and getting the right product to get you through the winter is essential.
