HVAC, which stands for heating, ventilation, and air conditioning, is the system that most homeowners use to keep their homes comfortable throughout the year.
There are many types of air conditioning systems: ducted, wall-mounted, and cassette. However, in this article, we will look at two different types of systems, each with its own set of benefits. The main differences between them are in configuration and performance. However, ultimately, they do the same thing – cool and heat your home.
The packaged unit is an all-in-one system that is great for spaces without a crawl space, while the split system has separate components for those with more space. Depending on the type of home you have, either one will be the best choice for you.
What is a modular HVAC unit?
A packaged HVAC unit contains all the parts of the system in a single metal cabinet. The evaporator coil, condenser, and compressor are housed together to save space inside. Often, the cabinet is placed either on the ceiling of the home or building or on a cement slab outside the home. A specially made duct connects the outdoor cabinet to all rooms in the home. Although the cabinet is outside, the actual functions of the complete air conditioning system are controlled indoors.

Some packaged air conditioning systems also include a natural gas furnace or electric heating coils. A packaged HVAC unit includes everything related to the air conditioning system in a single unit located outside the home. In homes with limited interior space to accommodate these systems or where there is a lack of underground space, a modular unit will be used.
What is a split system HVAC?
A split-system HVAC is designed for homes that have room for large indoor cabinets. A split-system model contains the condenser and compressor in an outdoor cabinet. Another indoor cabinet will contain the evaporator coil, and an air handler will send cool air through a duct system. A duct kit—copper tubing that connects the indoor and outdoor components—delivers cool air into the home.
Advantages of each type of ventilation
Both packaged and split HVAC systems have their advantages. Depending on the type of home you have, you may benefit from one of two sets of advantages.
Complete HVAC installation:
- Efficiency – Complete units are assembled in factories, which usually means they are more efficient than split systems.
- Easy installation. Since packaged units are only one unit, they are easier to install. This also results in lower installation costs and a smaller footprint.
- Less invasive – Since the package system is a single integrated unit, there is no need for additional refrigerant lines.
- SEER is an acronym for Seasonal Energy Efficiency Ratio, which in this block ranges from 13 to 18 and is considered good.
- Quiet – Since the entire system is located outside, you won’t hear any noise in your home.
Split system:
- Increased Efficiency: The SEER rating for split systems is typically 25 or higher, which is much better than packaged systems.
- Customizability – Because a split system consists of two components, placement is more flexible than a large modular HVAC unit.
- Low Maintenance: Ductless mini-split systems have much lower maintenance costs than any other air conditioning system.
- Added Value: Split HVAC systems are so energy efficient that they can potentially increase the resale value of your home.
Considerations for each type of HVAC.
The two different systems have their own set of considerations.
Complete HVAC installation:
- Roofs: If the condenser half of your system is located on the roof, improper installation can lead to leaks and other problems.
- Weather and Bird Damage: Since one part of the system is located outdoors, the entire system is susceptible to weather and bird damage. Many people have found that animals find a way to take refuge inside the packaged units.
- Service life – Packaged systems are susceptible to rust and therefore have a shorter service life.

Split system:
- A poorly installed HVAC split system can significantly reduce its efficiency.
- Labor intensive – higher installation costs.
- Leaks. A split HVAC system has more moving parts, so there is more potential for inefficiency. Cracks, gaps, and poor ductwork are just a few of the many problems that can occur with split systems.
For smaller homes, a packaged unit is best. This is because all the components of a packaged system are located outside. With less space to store HVAC components, you will be better off with a packaged system.
For larger homes or homes with a basement or crawl space, a multi-split system is best. This is because you have extra space to place the components in your home.
