As a family-owned and locally operated business, we have served the community for over 40 years. Our mission is simple yet powerful – to provide exceptional products and services that exceed our customers’ expectations.

If you’re looking for an eco-friendly way to keep your home comfortable year-round, ductless heat pumps are a great choice. Read on as we reveal the benefits of these incredible devices and how they work.

Understanding the Principles of Heat Transfer

So, how do heat pumps work exactly? Well, it all begins with the basic principle of transferring heat from one place to another. Put simply: ductless heat pumps use refrigerant to absorb and release heat from the air. 

Here’s how it works: When in heating mode, the refrigerant extracts heat from the air outside and transfers it into your home. This process is possible because even cold air contains some heat energy. The refrigerant absorbs this low-grade heat and then compresses it, raising its temperature. The hot refrigerant then travels through a coil in your indoor unit, releasing heat into your home’s air.

When in cooling mode, the process is reversed. The pump extracts heat from the air inside your home and releases it outdoors. By reversing the flow of the refrigerant, it allows for efficient cooling during hotter months.

The Indoor and Outdoor Components of a Ductless Heat Pump

A heat pump’s indoor and outdoor components work together to efficiently transfer thermal energy, providing an effective heating and cooling solution without requiring ductwork. Here are the primary parts of a ductless heat pump:

Indoor Unit

  • Evaporator Coil: The evaporator coil is the heart of the indoor unit – it contains refrigerant. As the refrigerant circulates through the coil, it changes from a low-pressure liquid to a low-pressure gas, absorbing heat in the process.
  • Blower Fan: When the heat pump is in operation, the blower fan draws indoor air over the evaporator coil, where the heat exchange occurs. Then, the fan pushes the heated or cooled air back into the room.
  • Air Filters: Air filters are essential to the indoor unit as they help maintain good indoor air quality. These filters trap dust, allergens and pollutants, ensuring the circulated air is clean and contaminant-free. 
  • Control Panel or Remote: The indoor unit may have a built-in control panel or remote control. These controls allow you to adjust the temperature, fan speed and mode of operation (heating or cooling) according to your preferences and comfort needs.

Outdoor Unit

  • Compressor: The compressor is the workhorse of the heat pump, compressing the low-pressure refrigerant gas to raise its temperature and pressure. This process allows the refrigerant to release the absorbed heat effectively during condensation.
  • Condenser Coil: The condenser coil releases heat collected during the heat exchange. As the high-pressure, high-temperature refrigerant gas flows through the condenser coil, it condenses into a high-pressure liquid, releasing the absorbed heat to the outdoor air.
  • Expansion Valve: The expansion valve is a metering device that controls refrigerant flow from the condenser to the evaporator. By reducing the pressure of the refrigerant, the expansion valve prepares the refrigerant for the evaporation process, allowing it to absorb heat again in the indoor unit.

Heat Pump Efficiency and Energy Savings

Heat pumps are an excellent choice if you want to be mindful of your energy consumption while maintaining a comfortable indoor environment. They are known for high-efficiency levels, which means they can provide significant energy savings compared to other heating and cooling systems. 

The primary factor contributing to a heat pump’s efficiency is its coefficient of performance (COP), which measures how much heating or cooling capacity it provides per unit of electricity consumed. Heat pumps generally have COPs ranging from 2.5 to 4 or higher, meaning they can produce up to four units of heating or cooling for every unit of electricity used.

4 Reasons to Choose a Ductless vs Ducted Heat Pump

When considering heating and cooling solutions for your home, you may find yourself at a crossroads between ductless and ducted heat pumps. Here are some reasons why ductless is the way to go:

  • Flexibility and Zoning

Ductless systems provide unmatched flexibility by allowing you to create personalized comfort zones in individual rooms or areas. Each indoor unit operates independently, so you can adjust the temperature according to the occupants’ preferences and the specific room’s heating or cooling requirements. 

  • Energy Efficiency and Cost Savings

These systems excel in energy efficiency in part due to the absence of ductwork, which eliminates the energy losses associated with ducting leaks and poor insulation. The ability to target specific areas of the home also reduces overall energy consumption, leading to lower utility bills and substantial long-term cost savings.

  • Installation and Renovation

Ductless heat pumps are easy to install, requiring only a small wall hole connecting the indoor and outdoor units. This makes them an excellent choice for retrofitting older homes or adding heating and cooling to new additions without the need for extensive renovations.

  • Aesthetics and Space

Ductless indoor units are sleek, compact and unobtrusive, making them an attractive option for homeowners. They can be mounted on the floor, walls, or ceilings, minimizing the impact on interior design and maximizing floor space.
