The IcyBreeze v2 Portable Air Conditioner is a great air conditioner solution for your car that has a broken air conditioner. This quality-grade 12v AC doesn’t require any installation. Just plug the battery in and you have an instant air conditioner.

How IcyBreeze v2 Portable Air Conditioner works? Ice and little water is filled in the Icybreeze cooler and the power is turned on. Air is then pulled from outside, to run across the cooling coils placed internally. The cooled air is blown out by the flexible hose. The hose directs the air to the required location. It is blown by a three speed fan keeping the area cool. This makes the product suitable for use by boaters, campers and even during sporting activities.

The 12v car AC also includes power source options namely a standard charger and a 12v 6AH Li-Ion battery pack. This unit has an optional 12v car adapter (sold separately) to maintain its cooling capability even for hours of traveling.

install portable ac in car


For ACs, we’re focused on its cooling capacity, what kind of ambient temperature it’s built for, filtration, the coolant used and a few of the smarter features that have now become common.



They are pretty large because they have to incorporate every component inside a single chassis. This also means that there are fewer things that a consumer has to worry about, and thus, the entire unit ends up being cheaper than the rest.

Window Air Conditioner

Such ACs are also termed monoblocks for this very reason. To mount a Window AC onto a wall, you ideally require about 9-12 inch thick walls. If your walls are thinner than that, an additional support structure will be necessary, or you’re better off looking for a thicker wall. 


+ Cheap 

+ Easy to install 

+ Monoblock design 


– Noisy 

– Needs a thick and sturdy wall for mounting 


Seen as an improvement over Window ACs, split ACs are made by separating the compressor and heat dispensing coils into an external unit which sits outside your home. Maintenance for split ACs is more difficult since the maintenance personnel have to access the external unit.

There are also certain limitations regarding how far apart the internal and external unit can be installed. The farther you place the two, the less efficient the combination becomes so you should ideally keep it low. That being said, these ACs can be installed up to 40 meters away from each other provided the interconnecting tubing is well-covered. Cassette ACs are a variant of split ACs in which the internal unit is mounted on the ceiling of the room. 


+ Expensive 

+ Makes less noise

+ Can be installed on any wall – Difficult to install


– Higher risk of coolant leaks 


When you’re trying to cool a room, you need to look at the size of the room, the number of heat sources, the ambient temperature of the geographical region, number of windows in the room and surfaces exposed to the sun. These factors play into the simple rules of thermodynamics, but we’re not going to teach you physics in this guide but rather drill it down into simple logic. 

What we’re presenting is a rather simple calculator. Simply pick the right option in each row of parameters. You should only pick one option in each row. There are ten rows in all. Take the score for each row and total it up to get the final grand total. Then refer to the chart to get the recommended tonnage.

In case, your score is higher than what this chart recommends, and you need to split the room into two logical parts and then use the above chart for each segment and then install two ACs in the room.

With heavy appliances, you’ll always see an energy efficiency rating applied. The Bureau of Energy Efficiency requires that every AC have a label indicating its efficiency on a 5-star scale. The more stars you have on this scale, the more efficient the AC will be.

ISEER Rating for Air Conditioners

The Energy Efficiency Ratio is simply calculated by taking the cooling capacity of the AC and dividing it by the power consumed by that AC. The chart below gives the Star rating applicable for the EER range.

These ratings go a long way in saving power consumption. A 5-Star AC can be up to 35% more efficient than a 1 Star AC. However, 5-Star ACs are also way more expensive, and it will take a couple of years before the higher cost evens out based on money saved for utility expenses.


Inverters are what convert DC (Direct Current) power to AC (Alternating Current) power. Within air conditioners, you first take the AC power from the wall socket and convert it to DC and then turn it back into AC for the compressor motor. Traditional air conditioners used to do this in a fixed manner so compressors would either be in an ON state or an OFF state. Inverter air conditioners are more dynamic with the switching frequency. This allows the compressor to work in a variable manner so effectively; you are varying the tonnage/capacity of the air conditioner as per your needs. This precise control helps you manage temperature better than traditional air conditioners.

However, getting to the right temperature takes a little extra time in inverter air conditioners as compared to traditional air conditioners. Because there is complicated circuitry involved, these inverter air conditioners are also more expensive to repair, especially when the main circuit board, i.e. the PCB goes wonky, you have to replace the board entirely. With traditional air conditioners, you could simply replace the individual components on the circuit board as they weren’t complex. Of course, if you were to get the parts list, you can always replace the components on an inverter air conditioner as well, but you’ll be stuck if the main microcontroller is messed up. You need to programme those before replacing them.

Since the capacity of inverter air conditioners is variable and more precise, you end up using just the right amount of power needed. This makes inverter air conditioners more efficient than traditional ACs. Certain manufacturers also use twin cylinder compressors which allow for greater control over the compressors. That, coupled with inverter technology, helps save power even more. However, complicated machinery tends to break down more often than simpler machinery. Here are the pros and cons summarised.


+ Uses less power

+ More consistent temperatures – Less reliable


– Expensive



Filters are capable of trapping particles and performing the function of an air purifier as well. These ACs come with a separate replaceable filter module, and the practice is more common in industrial HVAC systems that are meant to be installed for hospitals and clean rooms. Most home ACs don’t have such advanced filters. The ACs that mention PPM statistics for known pollutants rather than generic terms like “bacteria filters” are what you should focus on.


Certain ACs can heat the room during chilly winters. This is helpful since you can reduce the number of appliances require.


Timers allow you to program the AC to operate for a certain period before shutting down automatically. This is great if you want the room to be cooler when going to sleep and then want the AC to shut off automatically after a couple of hours.
