The indoor unit has an evaporator approximately 30’’ wide, 12’’ long, and 10’’ deep rectangular box mounted on a wall inside the room you want to cool.
An outdoor unit houses the compressor and is placed in any outdoor open space. It’s shaped like a square, and its average size is 31″ x 21″ x 12″, but the sizes vary between different models.
A wall-mounted mini split air conditioner is a type of air conditioner that is designed to be mounted on the wall.
The main advantage of these devices is that they don’t take up any floor space. They can be installed in any room and can be hidden behind a cabinet or a door.
A ceiling-mounted mini split air conditioner is a type of air conditioning system that sits on a ceiling and provides cooling and heating to the room.
A ceiling-mounted mini split air conditioner is an alternative to the traditional window or wall mounted systems. They are installed in homes and offices where there is insufficient space for other types of systems.
A floor-mounted mini split air conditioner is a cooling system that sits on the floor. It is a type of air conditioner that can be installed in many different places.
Floor-mounted mini split air conditioners are more expensive than window units, but they are also much more efficient and quieter.
The multi-split AC is a very common type of air conditioner that is used in residential and commercial buildings. The device has multiple indoor units which are connected to one outdoor unit.
The multi-split ACs are efficient because they can be installed in various places, such as on the wall or ceiling, which means that they can be placed near the areas where people spend more time.
The sizes, such as 1 ton, 1.5 ton, 2 ton, and so on, are defined by the AC’s capacity.
A 1-ton unit has 12,000 BTUs (more on this later). A ton describes the amount of heat that the AC can remove hourly.
We can help you to choose the right size of system for your space.
A mini split air conditioning system has an outdoor and indoor unit connected through pipes.
The indoor unit sucks the warm air in and passes it over a coil containing refrigerant fluid to cool it down. It sends the heated refrigerant (now vaporized) to the outside unit to be released in the fresh air and returns the cool air into the room.
This AC has fans in the indoor unit that function at different speeds, and you can also adjust the airflow direction.
You’ll need a handheld remote or mobile app to change the settings and temperature of your mini split AC. You don’t need any ducts, like the ones in a central air conditioner, to assemble a mini split air conditioner.
Here’s a simplified version of how mini split:
Now you know what a mini split air conditioner is and its advantages. Let’s discuss how long mini split air conditioners last.
The average lifespan of a mini split AC unit is 10-20 years, although some can last longer and work optimally.
The longevity of an AC unit depends on its frequency of use, maintenance, accidents such as excessive voltage fluctuations, quality of product, and environmental conditions.
You’ll need to drill just a few holes in the wall to mount the indoor unit and create an opening of 3 to 4 inches to pass the pipes connecting both units.
You have to insulate just one room instead of the entire house to decrease the power consumption of a mini split AC.
That makes its initial installation cost and time less than that of a central air conditioning system (if you have to build the ducts as well) but around the same as that of a window AC.
Mini split air conditioners solve a significant drawback of central air conditioning systems: the leakage of cool air while it passes through the ducts.
Some reports claim that this loss due to inefficient ducts results in almost 30% more energy consumption. Since mini split ACs are ductless, you don’t have to worry about losing cool air.
You can change the temperature of each mini split air conditioner independently of other units if you have them.
Now that you know what a mini split air conditioner is, you must understand that it’s a super cost-effective option for a small property such as a trailer or portable home, extensions such as a mud room or a home office, garage, studio apartment, or one room of the house.
Mini split ACs are more energy efficient than central air conditioning because they generally have a higher SEER score and zero ducts which means there’s no loss of cool air due to duct leakage.
If you’re not worried about the power bill because you have a large solar-powered space and the room’s aesthetics are important, then you might want to go for a central air conditioning unit.
Insulation costs can add up, and it’s necessary to do so when you live in a cold environment.
For example, the average insulation for a central air conditioning duct system is around $1- $6 per square foot.
Central air conditioning systems require insulation of all the ducts. You should go with a mini split air conditioner if you don’t want to spend much on insulation and its maintenance.
You don’t need to go into the details of what the BTU is. Remember that you’ll need approximately 20-25 BTUs for each square foot of space.
You can calculate the square feet of your room by measuring the length and width from one edge of the room to the other and multiplying the numbers together.
Then multiply this number by 20 or 25 to get the required BTU number.
For example, you’ll need a mini split air conditioner with approximately 6250 BTUs for a 250 square feet room. If you can’t find a mini split AC unit with the exact BTUs, go for the closest one.
Calculating the size of a round room can get complicated.
You should get AC installation professionals to do these estimations and tell you the size of the mini split AC you need.
Mitsubishi & Daikin are two of the leading mini split air conditioner producers. LG, Carrier, Panasonic, and PEL also have some great options.
A criterion for a great mini split air conditioner is a high SEER score (thus high energy efficiency) and cooling capacity (tonnage and BTUs).

A clogged condenser drain often causes water to backtrack and leak through the indoor unit.
You can fix that by checking the drain pipe for any accumulated dirt or mold and cleaning it.
Water dripping from your AC Inside the room can also indicate on a refrigerant leakage which freezes the inside unit coil.
Dust accumulates in the filters as the AC cleans the warm air that it sucks from the room. You should clean the filters every couple of months.
If you have pets, especially cats, clean filters monthly because pets’ fur particles can clog the filters. That activity can reduce your power consumption by 15%.
You can clean the filters by removing them from the unit, dusting them off, or vacuuming them and then rinsing them with clean water.
Dusty air, windy weather, and nearby foliage can collect on it, reducing the airflow through it and thus its efficiency.
It would be best if you took a small broom and gently scrubbed the coils to clean out all the debris whenever they’re dirty.
You should also avoid keeping lamps, TV, or other electronic devices that generate heat close to the mini split air conditioner’s thermostat inside the indoor unit.
The heat from these devices and even direct sunlight tricks the thermostat and causes your AC to run longer than it needs to.
A mini split air conditioner might be better for you than a central air conditioning unit, but that depends almost entirely on your specification, usage, room size, and other requirements.
The installation cost for any HVAC system depends on the location, accessibility to the location, and type of air conditioning unit. You should get a quote from us based on your specifications.
Yes, you can cool your entire house comprising multiple rooms by installing multi-split type air conditioners. Depending on capacity, one outdoor AC unit can support four to five indoor units.
You can DIY the installation of a mini split air conditioner. Still, it’s best to call HVAC installation professionals because they can ensure the fitting is correct the first time around.
On average, a 1-ton mini split air conditioner uses 1,200W (1.2 kWh/h). You can calculate the electricity consumption of ACs by multiplying the kW by the number of hours you run the AC.
