Split System Residential HVAC

A split system residential HVAC is an air conditioning and heating system divided into two components.

The outdoor unit contains the condenser, compressor, and fan, while the indoor unit houses the evaporator coil and air handler. This type of system is cost-effective and energy efficient, and it can easily be installed in most homes.

Indoor Unit

An indoor unit is a crucial component of a split residential HVAC system. It houses the evaporator coil, which absorbs heat from the air in your home and transfers it to the refrigerant inside. The evaporator coil handles cooling your home’s air, making it essential to an effective residential HVAC system.

When the outdoor unit sends refrigerant to the indoor unit, it passes through the evaporator coil and absorbs heat inside your home. This cools down the air, circulating through the ductwork and into your home.

Outdoor Unit

A split system outdoor unit compresses and pumps refrigerant through the system. It also houses the condenser coil, which helps to transfer heat from inside your home to the outdoor unit. The compressor is also housed in the outdoor unit. It handles compressing the refrigerant, which helps to create a cooling effect.

Some key points to consider about split systems include:

Zoning Capabilities

Split systems can be set up with several indoor units connected to one outdoor unit. With a split system, you can have different temperatures in different rooms or areas of your home. This feature can enhance comfort and energy efficiency.

Seasonal Energy Efficiency Ratio (SEER)

The SEER rating indicates the cooling efficiency of the system. Higher SEER ratings mean more significant energy savings. Look for a system with a SEER rating of at least 14 for better efficiency.

Noise Levels

Split systems are generally quieter than packaged systems. The noisiest component (the condenser) is located outside the home.

Pros of Split Systems

  • Energy-efficient, potentially reducing your energy bills
  • Flexibility, as components can be installed separately

Cons of Split Systems

  • Installation can be complex, requiring a skilled HVAC company
  • Not ideal for homes with limited indoor or outdoor space

Packaged Residential HVAC Systems

Packaged systems combine heating and cooling into one unit, making them perfect for homes with limited space. Some more points to consider about packaged systems include the following:

Easier Installation

All components are combined in one packaged unit. Installation is often simpler and faster than split systems. 

Maintenance Access

Maintenance and repairs can be more straightforward. It reduces labor costs because all the components are in one place.

Lower Indoor Air Quality

As the system is often located outdoors or in less insulated areas, it may draw in more dust and debris, potentially impacting indoor air quality.

Typically installed on the rooftop or near the foundation, these systems come in the following two varieties:

Gas/Electric Packaged Systems

A gas/electric system combines a gas furnace and air conditioner into one unit, making them perfect for homes with limited space. They use natural gas or electric heat to warm the air in your home while cooling it down via refrigerant passing through the evaporator coil. The condenser coils then transfer this heat outside, allowing cooled air to be circulated back into the home.

This type of system is cost-efficient and energy-efficient, providing heating and cooling within a single unit.

Heat Pump Packaged System

A packaged heat pump is an all-in-one HVAC system that combines a heat pump and air conditioner into one unit. This system is energy-efficient, as it can heat and cool your home using the same energy source.

Unlike a gas/electric system, a heat pump packaged system uses the outdoor air as its energy source. This makes it ideal for homes in cooler climates, as it can extract heat from the air and move it indoors.

Pros of Packaged Systems

  • Compact design, ideal for smaller homes or limited space
  • Simplified installation with fewer parts

Cons of Packaged Systems

  • Limited options compared to split systems
  • Potential for reduced energy efficiency
  • Noisier than other units

Duct-Free Residential HVAC Systems

Duct-free systems, or mini-splits or multi-splits, consist of an outdoor unit and one or more indoor units connected by refrigerant lines. They are ideal for homes that don’t have ductwork or are too small for a central HVAC system.

Duct-free systems are energy efficient and easy to install. They are also quieter than traditional central HVAC systems and operate on much lower wattage, making them perfect for homes that need to be cooled without running the risk of high energy bills.

Some extra information about duct-free systems includes:


Duct-free systems offer various installation options, such as wall-mounted, ceiling-mounted, or floor-standing indoor units, allowing homeowners to choose the best configuration for their space.

Inverter Technology

Many duct-free systems use inverter technology, which adjusts the compressor’s speed according to demand. This results in consistent temperatures, increased efficiency, and reduced energy consumption.


While duct-free systems are known for their visible components, manufacturers have made strides in designing sleek, modern indoor units that can blend seamlessly with your home’s décor.

Pros of Duct-Free Systems

  • Energy-efficient, as they don’t rely on ductwork
  • Ideal for room additions or isolated spaces

Cons of Duct-Free Systems

  • Higher initial costs compared to other residential HVAC options
  • Visible components, which not all homeowners appreciate
