What are Split Heat Pump Systems?

Have you ever noticed how expensive it can be to heat and cool your home? If so, you may have considered investing in a split heat pump system. A split heat pump system is an efficient, cost-effective way to heat and cool your home. It uses a combination of air-source and ground-source technology to provide the most efficient temperature control while saving on energy costs. In this blog post, we’ll cover what split heat pumps are, the components involved in this system, their advantages and disadvantages, and more. By the end of this article, you’ll have a better understanding of whether or not a split heat pump system is right for your home.

What are Split Heat Pump Systems?

There are two types of heat pump systems: split systems and packaged systems. A split system has an outdoor condenser unit and an indoor air handler, while a packaged system contains both the condenser and the air handler in one unit that sits outside.

While either type of heat pump can be used for heating or cooling, most split systems are used for cooling and most packaged systems are used for heating. In a split system, the air handler is usually located in the basement or garage, while the outdoor condenser unit is located on a concrete pad next to the house.

A split heat pump system uses two units to transfer heat: an outdoor unit that compressor and circulates refrigerant and an indoor unit that evaporates and circulates refrigerant. Most splits have one outdoor unit and multiple indoor units connected by copper tubing. The advantage of this type of system is that each indoor unit can be individually controlled, so you can have different temperatures in different rooms or areas of your home.

How do Split Heat Pump Systems Work?

Split heat pump systems are becoming increasingly popular in North America as an energy-efficient heating and cooling solution. But how do they work?

A split heat pump system consists of two main components: an outdoor unit and an indoor unit. The outdoor unit contains the compressor, condenser, and expansion valve, while the indoor unit houses the evaporator coil.

The split heat pump system works by circulating refrigerant through the two units. The refrigerant absorbs heat from the outdoors and transfers it indoors, or vice versa depending on whether you are heating or cooling your home.

The beauty of split heat pump systems is that they are very efficient, both in terms of energy use and cost. They are also relatively easy to install and maintain, making them a great choice for many homeowners.

Pros and Cons of Split Heat Pump Systems

Split heat pump systems offer a number of advantages and disadvantages when compared to other types of heating and cooling systems. Some of the pros of split heat pump systems include their efficiency, flexibility, and low maintenance costs. Some of the cons of split heat pump systems include their initial cost, noise levels, and potential for ice buildup.

Are Split Heat Pump Systems Right for You?

If you’re considering a split heat pump system for your home, there are a few things to keep in mind. Split heat pump systems are most effective in homes that have already been ducted for forced-air heating and cooling. They can also be used in homes with hydronic (hot water) heating systems, but may require additional installation work.

In addition, split heat pump systems work best in moderate climates. If you live in an area with very cold winters or very hot summers, a different type of heat pump system may be a better option for you.

Finally, it’s important to make sure that the company you purchase your split heat pump system from is reputable and has experience installing these types of systems. With so many options on the market, it’s important to do your research to ensure you’re getting a quality product.

How to Choose a Split Heat Pump System

When choosing a split heat pump system, it is important to consider the size of the space that needs to be cooled or heated. Split heat pump systems come in a variety of sizes, so it is important to choose one that will be able to accommodate the square footage of the space. It is also important to consider the climate in which the split heat pump system will be used. If the system will be used in a temperate climate, a less expensive model may suffice. However, if the system will be used in a more extreme climate, it is important to choose a model that is designed for that climate. Additionally, it is important to consider the energy efficiency of the split heat pump system. Some models are more energy efficient than others, so it is important to compare models before making a purchase.


Split heat pump systems are an energy-efficient way to heat and cool your home. They have the ability to provide efficient cooling during the summer months while still providing reliable heating during cold winter temperatures. Plus, they are often much more cost-effective than traditional air conditioning systems, which can make them a great option for homeowners looking to save money on their monthly utility bills. With split heat pump systems, you can enjoy all the benefits of climate control without having to worry about skyrocketing energy costs.
