Different Types Of Air Conditioners
Air conditioners have a fascinating history. They were not always the sleek, efficient machines you see today. The concept of air conditioning dates back to ancient times. The ancient Egyptians, for instance, hung wet reeds in their windows to cool the incoming breeze.
In the 20th century, Willis Carrier invented the first modern air conditioner in 1902. This game-changer paved the way for the diverse range of air conditioning systems today.
Today, air conditioners are more than just a luxury. They are necessary, providing comfort and improving the quality of life for millions worldwide. They play a crucial role in homes, offices, hospitals, and many other settings, making hot summers bearable and improving indoor air quality.
Various air conditioners are available today, each designed to suit different needs and preferences.
1. Central Air Conditioner
A central air conditioner is your top choice for cooling when dealing with a house with six or more rooms or spans over 2000 square feet.
Working with the blower and evaporator coil inside your furnace, a central air conditioner circulates air through ducts installed throughout your home. This system is often referred to as a central ducted system. You’ll find these systems in two main forms: split or package systems.
Package Systems
A gas package system is an all-in-one solution using natural gas or propane as the primary heat source, combined with an in-built electric air conditioner. Positioned outside your home, these systems connect to ductwork that delivers air conditioning to multiple rooms in your home. Typically, they are one-zone systems with ductwork situated inside the crawl space.
Split Systems
On the other hand, a split system features an indoor electric or gas furnace coupled with an outdoor condensing unit housing the compressor.
The outdoor condenser unit is the air conditioner, while the indoor furnace houses the evaporator coil and blower required for the air conditioner’s operation.
The refrigerant travels between the two systems via copper tubing. The refrigerant enters the air conditioner super-heated, is rapidly cooled to eliminate heat, and then returns to the blower. Here, it cools the air before distributing it throughout your home.
For a cutting-edge home experience, you can pair smart thermostats with central air conditioners.
Pros
- Central air conditioners are highly efficient at cooling large spaces and multiple rooms simultaneously.
- As the main unit is located outside, the noise level inside your home is significantly reduced.

2. Air Source Heat Pump
An all-electric system resembling a central air conditioner system, an air source heat pump stands out with its ability to provide energy-efficient air conditioning and heating, thanks to a reversing valve.
This reversing valve switches the refrigerant flow from heating to cooling mode, making these systems versatile. Air source heat pumps can be either split or package systems.
Package Systems
A package system is a self-contained unit that houses the evaporator coil, blower, compressor, and fan all within a single system. Positioned outside your home, it connects to ductwork that delivers air conditioning to multiple rooms in your home. Typically, they are one-zone systems with ductwork situated inside the crawl space.
Split Systems
A split system features an indoor air handler that contains an evaporator coil and blower, coupled with an outdoor condensing unit housing the compressor.
The refrigerant travels between the two systems via copper tubing. The refrigerant enters the outdoor condenser super-heated, is rapidly cooled to eliminate heat, and then returns to the air handler. Here, the blower distributes cooled air throughout your home. In heating mode, this process reverses refrigerant flow to heat the home.
Split systems can be multi-zone by adding damper doors into the ducts controlled by thermostats. You’ll need a thermostat to control each zone.
Programmable thermostats can control heating and cooling modes through auto settings to provide a smart home experience utilizing cutting-edge, best heat pump technology.

Geothermal cooling, a relatively recent and energy-efficient technology, is rapidly gaining traction worldwide.
The earth’s temperature stays relatively steady at 55 degrees Fahrenheit year-round thanks to its insulating qualities. This consistent ground temperature, regardless of the weather, is a key factor in the effectiveness of geothermal technology, enabling more efficient heating and cooling of your home compared to other technologies.
A piping system, often called a “loop” or “ground loop,” circulates water between your home, a heat pump, and the ground. Depending on the site’s topography, these polyethylene pipes can be laid vertically or horizontally.
In the winter, water flows through this earth loop, absorbing and storing heat from the ground. The heat is then compressed, raising the temperature, and delivered back into your home.
During the summer, this cycle reverses. The heat pump extracts excess heat and transfers it to the ground. The cooled air is then circulated throughout your home via ductwork.
This technology doesn’t rely on fossil fuels to generate cooling or heating. However, electricity is still required to operate the compressor, fan, and pump. You can power a geothermal system with solar energy for a completely green setup.
In Europe, geothermal heating and cooling is used in over 70 percent of new houses. More than 70% of new homes in Switzerland and Sweden now utilize geothermal technology.
