As the temperature rises, things can get uncomfortable inside. You may escape the heat outside by diving into a pool or sitting in the shade, but if you want to stay dry indoors during the blazing weather, you’ll probably need an air conditioner as well. There are many different types of AC available, including split systems with parts inside and outside the house, such as central air conditioners and ductless mini-split air conditioners, as well as stand-alone systems, like portable air conditioners or evaporative air conditioners.

3- Split AC


This sort of air conditioning system uses two independent components, one within your room and the other outside, to efficiently chill an area, as the name suggests. The indoor unit comprises an evaporator coil, a blower fan, and an evaporator coil and is often installed on a wall.

Types of AC

The compressor and condenser coils, on the other hand, are housed in the outside unit. Your home’s interior unit works together to circulate cool air. For this procedure to function, warm air must first be removed from your space, cooled, and then pushed back into it. In a split system, the refrigerant absorbs heat from the interior and transfers it to the outside, where an outside unit discharges it.

5- Spot Coolers


Boats and ships need these types of AC to maintain a pleasant temperature in their cabins and cargo sections. Spot coolers are specifically made for use in the rugged marine environment, withstanding high sunshine and salt water while delivering potent cooling in locations that would not have traditional air conditioners.

Types of AC

These spot coolers can be used to chill small and big areas on ships, including open decks and storage spaces, cabins, galleys, and wheelhouses. They may be movable, portable devices that may be quickly moved as needed or permanently installed aboard a boat or ship. Additionally, they have caster wheels for simple movement.

6- Rooftop Air Conditioners


For large commercial and industrial sites, rooftop air conditioners are a great alternative. High efficiency, cost savings, ease of installation, and minimal interruption to the building’s exterior are only a few of its many benefits. Rooftop air conditioners are more powerful and offer better cooling capacity than wall-mounted models.

Types of AC

Because they are fixed on the ceiling and do not require ducting, their installation is also relatively straightforward. The rooftop air conditioning unit (RTU) is exposed to various weather conditions due to its location on the roof, including heat, rain, snow, wind, and storms. This can increase the likelihood of wear and tear and shorten the RTU’s lifespan.

Facilities that maintain a constant excellent interior temperature benefit greatly from rooftop air conditioning installations. Therefore, they are perfect for industrial settings like factories, warehouses, and data centers.


7- Mounted Air Conditioning Units on the Wall


These types of AC units include two components: an interior unit and an outdoor unit. They are also referred to as split-wall AC units. The indoor device is fixed to a wall inside. The outdoor unit, which is often outside next to the indoor unit, is in charge of releasing the heat that has been gathered within the house.

Because wall-mounted AC units are placed on the wall, they can flow more air and chill the room more quickly and effectively than the typical window and portable AC units.

Types of AC

You may tailor your environment needs with the help of the many wall-mounted air conditioners. They have practical features like remote controls, temperature settings, and timers. However, it is crucial to be aware that these units may result in the wall getting hot to the touch because they run continuously.

8- Packaged Terminal AC Unit


It’s possible that you haven’t yet heard the name of this kind of unit. A type of air conditioner, a packaged terminal air conditioner, is made to heat and cool different rooms or spaces. They can be utilized in residential and commercial structures and are frequently found in hotels, motels, and other similar facilities.

Types of AC

The PTAC is made to be practical and straightforward to operate. They come as a single wall-mounted device and don’t need any extra ductwork. The evaporator, condenser, compressor, and fan motor comprise the PTAC, which functions as a cooling and heating system. The unit’s front is where the controls are situated, and they are simple to operate.


9- A Geothermal Air Conditioner


Geothermal cooling types of AC are a fantastic substitute for conventional cooling systems. It provides a green alternative for many homes because it heats and cools your home using the earth’s natural heat. Geothermal air conditioning brings natural warmth from the ground into your home through a network of pipes buried beneath.

This may result in significant monthly energy cost reductions. Compared to other types of air conditioning systems, they can save up to 50% on energy.


10- Evaporator Cooler


Swamp coolers are another name for evaporative coolers. Evaporative coolers, as opposed to conventional air conditioners, employ evaporation to chill the air. To function, warm outside air is drawn in and forced through water-soaked pads. Where the water evaporates, and cool air is released into the house. Compared to conventional air conditioning, these coolers can use up to 75% less energy to keep your home comfortable. They are often inexpensive to acquire and set up, and most don’t require extensive modification. Additionally, their maintenance costs are relatively low.
