Cold Climate Heat Pump Buying Guide

Now that we’ve seen some of the best dual-function air conditioner + heat pump mini-splits, it’s time to discuss how to choose one for your home. Here’s everything you need to know;

What is a Ductless Mini-Split Heat Pump?

There are three broad categories of heat pumps; air source, geothermal, and ductless mini-splits. 

  • Air Source Heat Pumps

The most commonly installed heat pumps, air-source heat pumps, have two parts – an indoor unit (known as an air handler) and an outdoor unit (known as a heat pump). Line sets connect the two parts, and, inside the line sets is refrigerant that circulates between the indoor and outdoor units, absorbing and releasing heat as it moves back and forth. 

  • Geothermal Heat Pumps 

Geothermal heat pumps are slightly different. Also known as ground and water source pumps, they move heat through a series of pipes buried in loops outdoor. The tubes can be buried vertically or horizontally. Inside the tubes is a water solution that is warmed by the constant 50-60 degrees F temperatures in the ground. The water solution circulates into and out of your house. As it passes through the house, the heat dissipates into your rooms.

  • Ductless Mini-Split Heat Pumps

Finally, owing to efficiency issues with both air source and geothermal heat pumps, a new line of heat pumps was designed – known as ductless mini-splits ac. Like air-source heat pumps, mini splits have an outdoor component and at least one indoor unit (some have two or more indoor units). The outdoor unit is known as the compressor/condenser, while the indoor component is the air handler. 

How Ductless Mini-Split Heat Pumps Work

a flowery home with the best mini split heat pump for cold weather

Ductless mini-split heat pumps don’t require ductwork. The quiet indoor unit is installed high on a wall or on the ceiling and operated through a remote control device. The condenser, meanwhile, stays outdoors. The components are then connected using tubes. In most cases, these tubes are run through the wall. A hole, often 3 inches wide, is drilled through the wall, and all line sets and electrical wiring connecting the two components passed through that hole. 

An eco-friendly refrigerant (often R410A) circulates through the tubing and plays a starring role in delivering heat to your indoors. 

What happens is that when the wall mounted air conditioner and heat pump is turned ON, it draws warm air from outside the house, and as the air passes through the refrigerant, the heat in that air is extracted and dumped into your rooms through the air handler. The cool air (from which the heat was extracted), meanwhile, is dumped outside the house. 

Are Ductless Mini-Split Air Handlers Good for Home Heating?

Absolutely! Ductless mini-split heat pumps are some of the most efficient heat pumps you can buy. The cooling efficiency of heat pumps (or ACs with in-built heat pumps) is measured by SEER (Seasonal Energy Efficiency Ratio), with the federal minimum standards set at 13 or 14-SEER for new units depending on location. 

The heating efficiency of these appliances, meanwhile, is measured by HSPF (Heating Seasonal Performance Factor), with the federal minimum set at 7.7. As you can see from the above reviews, most mini splits exceed these standards.

What we want to stress, though, is that you pay greater attention to the HSPF value if you’re primarily concerned with heating. According to the American Council for Energy-Efficient Economy, the target should be 8.5 HSPF or more. If you’re buying a dual-function AC +heat pump mini split, however, try to balance the SEER and HSPF values. A 15+ SEER and 8.5+ HSPF rated unit would be excellent. 

Another thing we have to mention is that new heat pumps work well in most parts of the country, but are at their best in areas that don’t experience extreme temperature fluctuations and situations where only moderate heating is required. In extreme temperatures, such as below 10F, you’ll need an auxiliary heat source. 

Considerations When Selecting a Ductless Mini-Split Heat Pump

Aside from efficiency, two other vital factors when choosing a mini-split heat pump are the size of the unit and convenience features. 

  • Size

How much space are you looking to heat? This should be the first question you ask. If you buy a heat pump that’s either too small or too big for your home/space, you will either not heat the area sufficiently or have an overly large unit that has to go ON and OFF repeatedly during operation to avoid overheating the space. This repeated ON/OFF activity shortens the life of heaters. 

HVAC professionals refer to the Air Conditioning Contractors of America (ACCA) Manual J to determine the right size heater or AC for a given space after taking into consideration; the home’s foundation, wall thickness, insulation values, air filtration, openings, and other factors.

  • Convenience Features

Convenience features are any extras included in the appliance to make your work easier and give you more comfort. Three such features that you’d want to focus on are; noise output, demand-defrost control, and reverse cycle chillers. 

For noise, we recommend heat pumps rated at 76 decibels or lower. When it comes to frost control, frost accumulation is a massive problem in the outdoor compressor unit. Frosting can impede energy efficiency and compromise indoor comfort. 

Models with demand-defrost control allow you to defrost the condenser anytime to minimize inefficiency issues. Finally, reverse cycling chillers make it possible to pair the heat pump with a wide range of heating and cooling distribution systems for even greater comfort in the home.

How to Get more from your Mini-Split Heat Pump

Most mini-split heat pumps are incredibly efficient. But, you can always boost efficiency by helping the heater in several ways, including;

  • Prepare for supplemental heating

Although a medium-sized mini-split can comfortably warm an average-sized room, this is only practical in moderately cold seasons. Whenever the temperatures dip too low, the heat pump alone may not generate enough heat to keep you warm round the clock. In these situations, you may need a supplementary heat source such as an electric resistance heater.

  • Mount the indoor close to the ground

Most homeowners don’t take this seriously, but the way you install the indoor air handler has a big say on the ease and efficiency of heat distribution in your room. The unit should be installed at least 15 inches off the floor, with sufficient clearance in front of it. This way, the air handler gets to pull cool out of the room more easily. 

Also, at close to floor level, warm air isn’t blown directly on occupants. Instead, the air is blown across the floor and mixes with cold air, generating the perfect indoor air conditions. It’s also easier to access the filters for cleaning when the indoor air handler is closer to the floor.

  • Right size the pipes too

Most mini-split air pumps come with line sets to connect the indoor and outdoor units. The most important thing here is that the two components (condenser and air handler) should be far apart enough to ensure that no noise transfers from the outdoor unit to the indoor unit. At the very least, the components should be 15 feet apart.

Other measures

Other than preparing for supplemental heating, mounting the indoor unit close to the ground, and right-sizing the pipes, we also advise that you;

  • Add insulation to your attic and walls
  • Add weather stripping around doors and caulk around windows
  • Install and set programmable thermostats to automatically adjust heat output as appropriate

Wrap Up

As you can see, ductless mini-split heat pumps would be a great source of supplemental heating in the home. Indeed, you can even use a mini-split heat pump as the primary heat source during the not-so-cold months. As with other mini-splits, though, make sure to find the right size unit for your home.
