What is A HVAC Split System?
A split HVAC system is an air conditioning system or heating system that has both indoor and outdoor units that are connected with copper tubing.
Traditionally, the outdoor portion of the unit contains the compressor and condenser, and the indoor portion of the unit contains an evaporator coil and indoor air handling unit that sends the air through the ductwork in your home. These types of home cooling systems are different from HVAC packaged units, where all parts are packaged together in one unit.
There are many different types of split systems, which can include heat pump systems or air conditioning systems (larger homes might require multiple split system air conditioners ) installed outside your home, paired with either a gas furnace or a fan coil located inside your home.
5 Different Types of Split System Cooling and Heating Systems
1. Split System Heat Pumps
Heat pumps run on electricity and draw heat from outside air—even cold air—and transfer it indoors. The outdoor unit houses a compressor and heat exchanger, and the indoor unit has an air handler and fan that circulate the air inside the home.
2. Split System Air Conditioners
Split-system air conditioners are units with the condenser and compressor placed outdoors, and an indoor unit containing the evaporator, furnace, air handler, and air filters.
3. Furnaces
Furnaces are indoor units that burn fuel, like gas or propane, to heat up the air, then distribute it through ductwork in your home.
4. Fan coils
Fan coils are indoor units that move air over the coil, heat or cool it depending on the weather and season, then distribute it through ductwork in your home.
5. Ductless vs. Ducted Systems
Split-system HVAC can be ducted or ductless. Ducted split systems use ductwork to circulate the warm air generated from your furnace, fan coil, or heat pump, and the cool air generated by your air conditioner, heat pump, or fan coil. Ductless mini split systems use small air handlers located in specific areas in your home to heat or cool that individual space.
What Is A Split Air Conditioner's Benefit?
Split HVAC systems have many benefits compared to HVAC packaged units. However, it is important to keep in mind that different types of ducted air conditioners and mini split air conditioners have benefits for different types of homes, apartments, and condos. While one HVAC system might be best suited for one type of home, it may not be best for another. Our dedicated team of Carrier experts can help you determine the best type of split HVAC system for your home and budget.
Efficiency
The efficiency ratings for HVAC split systems can range from the minimum efficiency allowed by the Department of Energy (DOE), to high-efficiency systems with ratings up to 24 SEER2. Split systems that are Energy Star® certified are considered much more energy efficient than those that rated the DOE minimum efficiency standards. Having a more energy-efficient unit can help you to save money on heating and cooling costs, which are traditionally the most expensive parts of your energy bill.
Customization
HVAC split systems have two separate components, which allows for more customization in the setup of the system.
Out of Pocket Savings
Installing a high-efficiency ducted air conditioner or mini split AC system can help save money by reducing energy costs, especially when it offers both heat and cool functions for year-round use.
Additionally, if you add zoning, you can control the temperature in individual rooms, further reducing energy use in spaces that don’t need constant conditioning. This targeted cooling and heating approach can also help reduce your energy bills.
What Is A Split AC Unit Downside?
More Expensive Installation
Since there are two separate units that comprise the system, split HVAC systems tend to be more expensive to install compared to HVAC packaged units. The AC installation costs can also increase if the two separate units have to be installed farther apart. The installation costs can vary widely for different types of HVAC split systems, and ductless systems can have more expensive units, but don’t require any air ducts to be installed in your home. Learn more about air conditioner price.
If regularly scheduled AC maintenance is not performed, the unit can be pretty noisy, which can hinder your experience in your yard or on your patio. This can also cause problems if you’re a light sleeper and the split system air conditioner is placed close to a bedroom.
The Outdoor Unit Requires Space
Since part of the system lives outdoors, there is space needed for the outdoor split air conditioner. This makes it difficult to install these systems if you have a small yard or outdoor space.

Frequently Asked Questions
Need Help? Find Quick Answers to Common HVAC Concerns
Q: Do I Need to Cover My Heat Pump in the Winter?
No, covering your heat pump during winter is not recommended. These units are designed to operate in all weather conditions, and covering them can restrict airflow and cause moisture buildup, potentially damaging the system.
Q: How Can I Find the Unit Size That Matches My House?
Determining the appropriate HVAC unit size depends on factors like your home’s square footage, insulation quality, number of windows, and more. A detailed load calculation by professionals can help identify the right unit size for optimal comfort and efficiency.
Q: Is It Safe to Plant Shrubs or Flowers Around an Outdoor Unit?
While landscaping can enhance aesthetics, it’s important to maintain at least a two-foot clearance around the outdoor unit to ensure proper airflow and ease of maintenance. Regular trimming is advised, especially in areas with rapid vegetation growth.
Q: Should a Thermostat Be Set to the “Auto” or “On” Position?
Setting the thermostat to “Auto” is generally recommended for energy efficiency, as the fan operates only when heating or cooling is needed. However, the “On” setting can provide continuous air circulation, which may be preferred for consistent airflow and filtration.
Q: What Do Rating Numbers Mean?
HVAC systems have efficiency ratings like SEER (Seasonal Energy Efficiency Ratio) for air conditioners and heat pumps, and AFUE (Annual Fuel Utilization Efficiency) for furnaces. Higher ratings indicate better energy efficiency, leading to cost savings and environmental benefits.
Q: What Does AFUE Stand For?
AFUE stands for Annual Fuel Utilization Efficiency, representing the percentage of fuel converted into usable heat by a furnace. A higher AFUE rating signifies a more efficient furnace.
Q: What Is the Difference Between a Split System and a Package Unit?
