Nowadays, the main concern for innovative products is efficiency. While both time and money are treasures, the demand for efficiency in the everyday work life is paramount. With the advent of the heating, ventilation and air-conditioning (HVAC) system, the evolution of both warming and cooling to buildings has become the standard mode of operation within the circulation of airflow to regulate temperatures within such structures, especially new construction.
While operating, the HVAC does more than just heat the unit, although this simplified name is a heat pump. Of course, heating is necessary during colder months, and they also provide humidity control for comfortability. During the warmer season, a heat pump transitions heat from the natural air outdoors into a cooling sensation indoors, and the reverse is also true during colder months.
Heat pumps but transport heat, so the toggling back and forth is much more efficient than without other heating and cooling systems like the box air-conditioner and other heating systems. Industry-standard improvements in efficiency make the HVAC have a new name. And it is called the split system heat pump that offers maximum efficiency during use in today’s world.

To better understand how the split heat pump system works is to have a foundation on the operations of the conventional HVAC system. The standard HVAC system cools the building comparable to a refrigerator that keeps food cold. Fans blow a refrigerant-filled coiling system that travels cooler air utilizing a compressor. The warmer air is captured by the refrigerant and transported away from the cooling system by way of air ducts.
Similarly, the heating system for the HVAC clothes combustion gases manufactured by burners by way of a heat exchanging system spread throughout the building through air ducts. Therefore, an HVAC system provides both heating and cooling all within one unit. Having a firm understanding that science and technicians have produced, this is the basic concept of the whole process, although in an exceptional simplistic form.
What is a split system heat pump?
The split system heat pump has components that work well indoors and outdoors, but they work together. The exterior of the structure is where the condenser should be, which maximizes the refrigerant’s flow along with an elevated amount of pressure that pushes the refrigerant gas throughout the compression. Inside of the structure is where you will find the air handler that cycles and regulates the airflow. There is a protected conduit that connects both components.
The split system heat pump operates ductless. Therefore, this is one of the significant advantages of the invention. Some models provide multiple indoor air handlers connected to one single outdoor condenser. Each air handler controls individual thermostats, which can regulate temperatures in different rooms that conserves energy and saves money.
With the absence of a duct system, a heat pump fills the void of the 30% of energy loss through the duct system. However, a direct distribution of air travel from the air handler into a specific room, if so desired. Based on this, air handlers function well within a structure such as from the ceiling, floor or mounted on a wall, which allows for creative designs and flexibility.
As a result, the split system heat pump enjoys the term efficiency associated with it due to the absence of the duct system and enhancements to traditional HVAC systems.
How does a split system heat pump work?
Through copper piping, the split system connects indoor and outdoor units. The outdoor unit has a coil that transfers heat, while the indoor unit contains a coil and a fan. The indoor unit circulates air through its ventilation system with the assistance of Freon gas. The Freon gas is a coolant that absorbs heat from the air.
When needing to warm a structure, absorbing heat by the Freon gas is accomplished by moving air over the coil by way of the outside unit. Once the gas heats to the proper temperature, gas moves to the coils of the indoor unit. As gas functions in the copper piping, heat permeates through the metal of the coil. From the fan, air moves over these coils, which then processes the heat throughout the heated ventilation duct within the structure. This process makes the split system heat pump and air cooling system with the technology to reverse at any time to provide warmth when needed.
During warmer months, heat within crosses over the coils of the inside unit. This transfer allows the Freon gas to capture the heat from the interior air of the coils. While both moisture and heat dissipate, the gas then transmits the heat through the copper piping to the outdoor compressors unit. During the transmission process of the air and passing over the coil, heat releases into the atmosphere.
What do I look for when purchasing a split system heat pump?
- Environment Heat pumps can operate at maximum efficiency throughout many climates across the world. However, in climates with temperature fluctuations throughout the day not as broad, the longevity of the pump is extended. In colder climates, beware of the need for an ancillary heating system as outlined when the temperature falls below 25°.
- Energy Efficiency To maximize the cooling option of the pump, the use of the air-source and ductless-split systems is under constant scrutiny with the utilization of the seasonal energy efficiency ratio (SEER). For new units, federal mandates require a minimum of 13 SEER in the Northeast and the more mountainous states like the Midwest and the Pacific Northwest.
Outside of these regions, a 14 SEER is the minimum requirement mandated in the industry. For both the air-source and ductless-split systems, heating efficiency is monitored by HSPF (Heating Seasonal Performance Factor), in which the minimum rating is 7.7 regardless of unit. Warmer environments need a higher SEER to operate optimally, while colder climates would function better with a higher HSPF. Regardless, pursuing a split system heat pump with a minimum of 15 SEER and 8.5 HSPF is recommended by the American Council for an Energy-Efficient Economy. Seeking a heat pump that has 18 to 27.5 SEER and 8.5 to 12.5 HSPF is most efficient.
When using a geothermal heat pump, monitor the rating by the Energy Efficiency Ratio (EER) to establish a higher efficiency rating and for heating by COP. Ensure that you stay within a range of federal guidelines minimums, which are 17.1 to 21.1 for the EER and 3.1 to 4.1 for the COP.
Remember that an increase in the rating will result in a higher purchase price. It is typical for efficient heat pumps to cost thousands of dollars. Still, a generous savings may possibly appear on your energy bill by merely replacing older units with much more efficient units, especially by monitoring the Energy Star rating.
- Size The size of the pump matters as it relates to your utility bill. A too little or too big heat pump may do more harm than good. For example, a heat pump that is too large for the structure will cost unnecessarily more to purchase, and the on-off repetitive cycling shortens its lifespan.
Hiring a heat pump technician fluent with an Air Conditioning Contractors of America (ACCA) Manual will help you in calculating the correctly sized unit for the structure in question. The factors that determine the right size are as follows:
- The structure’s foundation
- The thickness of walls
- The type of insulation
- The length and breadth of windows
- The airflow
- The other mitigating factors
- Incentives Federal tax credits of 30% are available for most geothermal heat pumps that were purchased by December 31, 2016, and were Energy Star-certified. The Department of Energy and the Internal Revenue Service has further details and how to take advantage of these federal incentives.
Additionally, checking your local guidelines would prove to be beneficial as states may offer state-specific inducements on geothermal systems. Also, utility rebates and federal credits may be available for other heat pump systems too. One source for identifying state-by-state enticements would be the guidelines set forth by the NC Clean Energy Technology Center.
- Noise Nothing is more irritating than a no noisy fan. Purchasing an air source heat pump with less than 7.6 bels is best. Position your unit away from windows near locations where noise can be absorbed. Protect the pump by reducing exposure from high winds, that decrease defrosting challenges. For example, obstructing the unit by aesthetically pleasing shrubs is ideal.
- Defrost Control Energy efficiency diminishes if there is a consistent frost accumulation on the heating pump. Choosing from a defrost control option will minimize any indoor discomfort. Reducing defrost cycles extends the longevity of your unit and provides cost savings.
- Reverse Cycle Chiller A reverse cycle chiller works well with many cooling districts patient systems, which leads to a much more comfortable temperature within the structure. Such technology decreases energy bills during the winter and provides exceptional benefits in units that are all-electric.
To maximize the use of your heat pump purchase, carefully analyze the heating and cooling efficiency potential of the structure before the purchase. After optimization, the opportunity to reduce your expenditures on a heat pump increase.
