The Best Mini Split Heat Pumps for 2023 Posted on June 7, 2023 Mini splits are an excellent choice for cooling. They are flexible, being able to cool one or multiple rooms connected to a single outdoor unit, and they do not require ducts, which makes them more cost-effective and energy efficient than traditional forced air duct systems. But mini splits can do more than just cool: they can act as supplemental heat sources too! When the weather cools and summer gives way to fall, a mini split heat pump can provide heating. There are even cold-climate models specifically designed to excel in low temperature conditions. In this guide, we explore mini split heat pumps and provide recommendations for mini splits that offer both cooling and heating. What is a Mini Split Heat Pump? A mini split works by circulating refrigerant to cool the air that is pumped into the home, providing indoor cooling. A mini split heat pump is a model that also provides heating in addition to cooling. It does this by reversing the flow of refrigerant: instead of transferring heat from the inside to the outside, it transfers heat from the outdoor air to the inside of the home. For more information, check out our Mini Split Heating 101 article. Pros of Mini Split Heat Pumps Two-in-one function Instead of using a separate heating source like space heaters, mini split heat pumps provide both heating and cooling functions in one package. That’s one less appliance to buy and take up space. Convenient installation Mini splits need only a small hole to connect the indoor units with the outdoor unit. This makes them cheaper and easier to install. Efficiency Ductwork can account for up to 25% of energy loss in traditional forced air systems. By eliminating the need for ducts, mini splits are much more efficient when it comes to cooling and heating. In fact, EnergyStar-rated mini split heat pumps use up to 60% less energy than conventional electric radiators. Not only is it good for your wallet, it’s good for the environment too! Individual zone control Because mini splits have separate indoor units, the temperature of each space can be customized compared to central air systems. For example, you can opt not to raise the temperature in rarely used or unoccupied rooms, allowing you to save even more. Safer Unlike ventless gas heating sources, mini splits do not generate combustion byproducts like carbon monoxide or NOx. This makes them much safer, especially for households with young children, elderly family members, or those with respiratory problems. They also provide a safe alternative for areas where ventless heating is not allowed. How to Choose the Best Mini Split Heat Pump Heating capacity The heating capacity of a mini split heat pump is measured in BTUs, or British Thermal Units. The higher the BTU, the more heat it can generate. Sizing Proper sizing for heating is complicated and needs to take many factors into account. While some online tools can be used to give you a general idea, the only way to really know what size unit is needed is to have a trained professional do a sizing calculation for you. This is generally done on site so that the professional can analyze all relevant factors like the level of insulation, air tightness, and many other areas. Efficiency rating When it comes to heating, the efficiency of a mini split heat pump is measured in COP, or Coefficient of Performance. COP is the ratio of how much heat a heat pump can generate given a certain energy input. In other words, it measures how much heat it can produce for every watt of energy. So if the heat pump has a COP of 2, it gives out 2 watts of heat for every watt of electricity used. The higher the COP, the more efficient the mini split heat pump is. A good mini split heat pump typically has a COP ratio of 3 or more. EnergyStar rating Energy Star is a program by the EPA and Department of Energy that provides information on the energy consumption of consumer products. Appliances with the EnergyStar label are certified to be more efficient than their non-certified counterparts. According to the DOE, an EnergyStar-certified mini split heat pump can be up to 60% more energy efficient than an electric radiator. They also save up to 4,500 lbs of greenhouse gas emissions during their operational lifespan. Cold climate considerations Some mini splits are not rated to be primary heating sources. For those living in colder regions, there are specific mini split heat pumps designed to provide higher heating capacity and efficiency at low outdoor temperatures. Look for models rated for cold climate performance. EnergyStar certification requires third-party verified performance for low temperatures down to 5°F.

The design uses Friedrich’s FastPro Technology, which makes installation and maintenance a much easier, less time consuming task. FastPro gives your HVAC technician easy access to the entire indoor unit, including piping, wire terminal, the fan and fan components. The front panel of your wall unit can be propped open with sliding bolts to keep the cover up and out of the way. If more room is needed to work, there is a slide bar than can be pushed out for a wider space. This makes installation of the refrigerant lines and wiring a much more manageable, less time consuming task for your HVAC technician. Finally it uses inverter technology that runs the compressor at a lower speed instead of shutting off completely. This helps the system to maintain the set temperature much more efficiently, while generating less noise than the on/off clicks of a non-inverter mini split.
