Ductless Mini-Split Heat Pump Buying Guide

Ductless systems allow you to heat and cool your home without adding costly and inefficient ducts (ducts are used with forced air furnace systems). Ductless heat pumps are the best alternative for replacing baseboard and wall-mounted electric systems. They’re also a great option for replacing propane, wood, or even gas systems. Ductless systems also provide cooling in the summer, making them ideal replacements for window box A/C units, and more affordable than central air.

How Ductless Heat Pumps Work

Ductless heat pumps units (the outdoor compressor and indoor head) are connected by small pipes that carry refrigerant. The refrigerant conditions the air by removing heat.

In the summer, the system removes heat from inside your home and sends it outside. In the winter, the system removes heat from the air outside and brings it into your home. This keeps your home a consistent temperature year-round at a much lower monthly cost.

Why Are Ductless Heat Pumps So Efficient?

Ductless heat pumps are a simple, sensible solution. Ductless systems keep the temperature consistent in your home by using something called inverter technology. This allows them to avoid inconsistent temperature variations that occur with conventional heating systems. They use varying-speed compressors to deliver only the optimum amount of refrigerant. Unlike other heating systems that blast air in just one spot, ductless systems distribute air evenly throughout the room.

Today, 90% of homes in Japan, most homes throughout Europe, and many homes in other countries around the globe use this technology. But even with the increased savings, the biggest benefit our customers mention is improved comfort.

Ductless systems also provide cooling during the summer, making them an incredibly versatile choice for Pacific Northwest homes.

Are ductless mini-splits good for heating and cooling?

Ductless mini-splits are good for both heating and cooling your home. A ductless system will keep you and your family warm in the winter and cool all summer long. 

Do ductless heat pumps work in cold weather?

Yes, ductless heat pumps work very well in cold weather. Your mini-split can usually heat to a low outdoor temp of -5 degrees, or in some cases lower. Its efficiency keeps your home comfortable on its own most of the time. However, on those extremely cold days, if you feel your ductless system needs a boost, you can run your backup heating system in addition to or instead of it. Although running only your ductless system will be the most efficient, adding a backup heating system on the coldest of days is okay, too. It ultimately depends on your comfort preference.

Do I need ducts for a ductless heat pump system?

A ductless heat pump system operates without the use of ductwork. It's great for older historic homes without ductwork, or for newer additions to a home, such as for a sunroom, mancave, garage, or other add-on.
