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?
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.
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
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.
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.

A heat pumping system functions slightly differently from the HVAC system. The HVAC system uses fans and burners to produce the desired air. Still, a heat pump system comes with fans and heaters that utilize its air through the air cycling principle.
Akin to the example of the refrigerator, heat pumps push colder air out of the building when warmth is needed and draws in warmer air. When cold air is needed, warm air dissipates from the structure and colder air enters. The cooler air is then transported throughout the air ducts, as mentioned before, all through a beautifully packaged unit. The unit itself sits outside of the building as air travels through the duct system, which distinguishes the package from the split system heat pump.
Types of Heat Pumps
At the most basic level, there are three types of heat pumps which are:
- Air-Source Heat Pump
- Split-Ductless Heat Pump
- Geothermal Heat Pump
Regardless of the kind of heat pumping unit, a technician proficient in installation will determine the correct size and product for your building.
- Air-Source Heat Pumps
The most common pumping system is the Air-Source Heat Pump. This pumping system contains two parts that are the indoor and outdoor units. With the use of a refrigerant, air circulates between both groups through tubing technology that absorbs and excretes heat by toggling backward and forward.
These pumps provide a reduction of heating costs on average of 50% compared to other heating furnaces and baseboard heaters. Additionally, the fan capabilities perform better than some central air-conditioning systems, which leads to a more comfortable environment during warmer times of the year.
Once upon a time, the Air-Source Heat Pump system was ideal for warmer temperatures. However, colder climates like the Northeast and Midwest, are now considered viable options for a unit such as this. Hence, when temperatures drop below 25°, an auxiliary heating system will be needed.
- Split-Ductless Heat Pumps
The Split-Ductless Heat Pump has two components, which are the outdoor compressor with up to four indoor air handlers. Their installation is generally mounted high on either a wall or ceiling and function by remote control technology. They are quiet operating units that also go by the name of a mini-split. They also circulate refrigerant throughout the component that connects the indoor and outdoor units.
These systems don’t require ducts to be used and are generally utilized in single-room buildings or for those structures that have no tubes. These mini splits bypass energy losses affiliated with duct work, in which 30% of the building’s energy consumption for space conditioning requires monitoring. With the assistance of federal incentives, the expensive installation costs decrease.
- Geothermal Heat Pumps
The Geothermal Heat Pump, some are known as a groundwater source, transport heat through various types that are embedded within open-air loops. A solution contained within the pipes warms the water to around 50 to 63 degrees (Fahrenheit). Sometimes, other water sources are used transport the water throughout a building.
These heating pumps manage humidity and often reduce energy consumption from 25% to 50% compared to other systems. One of the advantages is that they are quiet and can last a very long time. For example, indoor units may remain in service for around 25 years and the corresponding loops around 50 years. Minimized maintenance and technological enhancements allow the system to operate well in extreme temperatures.
Consequently, these units are not ideal for smaller constructions. Additionally, the installation can be expensive, like upwards of $25,000 for a 2500 ft.² structure. Due to various financial incentives offered by federal and local governments, the installation of this type of unit may be ideal.
A mini-split pump system is a way that someone can heat their home without any air ducts. Heating systems that use ductwork are the most common in homes and offices. However, more and more people are starting to switch from these traditional heating systems to a new mini-split system. They are made up of two important components. The compressor/condenser is located outside of the home. While the air handling unit is placed indoors to circulate the air. There a couple of other components as well. These are linked by a conduit that consists of suction tubing, a condensate drain, refrigerant, and a power cable.
One of the main reasons that people choose to have one of these systems installed in their homes is because they offer overall increased efficiency. Since they offer a lot of variety when it comes to length and sizes, you should be able to install it virtually anywhere. The versatility of these systems is another reason that people feel like they should make the investment. They can be suspended from a ceiling, fixed on a wall, or even have it mounted into a drop ceiling. There is even a floor model that might come in handy for certain situations.
Another reason that people like these systems is because they are much more energy-efficient and do a much better job heating or cooling whatever room you are in. Traditional ducts are known to lose their energy just because of the way that they are designed. Some ducts can lose up to 30% generated heat by traveling through the ductwork. Since a mini-split pump does not require ductwork, it will not be losing any heat which will save you energy. This efficiency also makes them much more effective when it comes to heating up your home. They will heat up or cool down the room in just a matter of minutes.
However, just like anything else, there are some downsides when it comes to this system. The biggest complaint that people have about this system would be the fact that it is a pretty expensive investment up front. They will be able to save you more money in the long run but if you don’t have a sustainable chunk of money, it might not be the best decision for your budget. Another thing that people don’t like about these systems would be the fact that you can not install them yourself. It is not like a window air conditioner unit, you will have to get some assistance from an HVAC professional. Something that some people may complain about, but it might not be a big deal to others, would be the looks of it. It may look clunky or ugly in certain rooms but in others, it may look okay and you can style it better.
Even though these systems can be pricey, they are well worth it. If they are well maintained and taken care of, then they can last up to 20 years. While most of the other heating and cooling systems last between 10 to 15 years. To make sure that your mini split system will last for many years to come, you should get it serviced at least once a year. During this service, they will check the filter and replace it if necessary, as well as cleaning the pipe, coil, and condenser. They will also let you know if anything else needs to be done.
These systems can vary in price. Some are just a few hundred dollars, while others can cost thousands of dollars. There are a lot of mini split heat pump reviews online. However, here are just a few to help you choose the best mini split heat pump system for your home. When you are buying one, you should consider the price, along with where you will be placing it. To pick the best mini split heat pump system, you should also consider your needs. You should think about the size of the room that you will be putting. If you are looking into purchasing one here are a few mini split heat pump reviews that will help you make your choice.
Purchasing a mini-split system can be difficult. There are a lot of choices on the market and they are not cheap by any means. You will want to pick one that was designed to hold up through plenty of use and any weather conditions. Some offer WiFi capabilities, while others just use a simple remote. All you have to do is look at the features and decide which one is going to best fit in with your life. There is no sense in spending a lot of money on something if you won’t be able to use every single feature that it offers. Having the WiFi feature is not only cool but it can save you even more money in the long term. If you like to turn your thermostat down before you go to work or the store as a way to save money, then you will definitely enjoy this feature. Sometimes you are late or get rushed out of the door without having a chance to turn it down. However, if you have a unit in your home that has the WiFi feature, you can turn the temperature down with just a few simple touches on your smartphone. There are plenty of other things that you should consider as well, like how much space you have to install it, how much room are you trying to heat up and cool down, and of course, your budget. While these systems are meant to be installed virtually anywhere, some may be easier than others. This is something that you should strongly think about before making a final decision.
Now you can distinguish between the traditional HVAC and the benefits of the split system heat pump. Upgrading to the split system unit maximizes not only energy efficiency but also prevents the unnecessary outflow of cash. Of course, noise reduction and managing indoor temperatures will not only net peace of mind but also a more comfortable environment within a home or business. Operating with remote technology provides a seamless experience while remaining in total control of its operations. While the newer units have increased longevity over the traditional HVAC, the split system heat pump is the future. You are now armed with the information to make the decision in your determination for a best mini split heat pump systems.
