A Little Background

Ductless air conditioners are the best way to enjoy cool air indoors without having to set up air ducts around your house. Most often, air ducts are only best with specially planned homes and the installation of a centralized AC unit should be in the home’s original plan for best results. This is why you can just turn to a ductless AC to avoid the hassle of installing air ducts, especially if you have a very limited space or area.
The biggest advantage of a mini split system or ductless air conditioner system is the fact that you do not have to go upstairs or downstairs to do some duct work around the house. If your home is not really designed for a central air conditioner unit, you can just use a ductless system as an alternative. Ductless systems are zone cooling methods much like portable AC units.
A ductless air conditioner system is usually pretty expensive over traditional methods of air cooling. This is because ductless, much like LEDs and solar panels, is pretty much a newer technology, along with the inverter type technology that is associated with most newer units today. However, despite the large cost on the upfront, you’ll likely to save money later on due to its low cost of operation, making it economical in the long run.
Air filtering is one of the important aspects of having a ductless AC unit. This is because air is typically filtered better if you have a ductless system due to the quality of most of their air filters. Most of them can even have HEPA filters, which can be great at keeping the dust, pet dander, bacteria and pollen away from your home for a cleaner and healthier air indoors.
Ductless air conditioners can be coupled with a heat pump as well, like most larger AC units, because you can be able to reverse them for the winter, instead of going for the regular HVACs or centralized AC units that may run into some problems along the way more often and can be hefty with maintenance.
You can also set single zone or multi zone condenser units to enhance the cooling or heating ability of your system. Wall units can easily control the temperatures from different rooms into one single centralized thermostat. Ceiling cassettes, on the other hand, are great for apartments, condo units and dorms with small spaces.
If you want to install a ductless AC unit system at home, be prepared to have some budget for it, because it can cost more than you think it should. AC units that are ductless can cost from $3,000 to $5,000 depending on whether you include indoor heating as well. While they are great alternative to regular HVACs, they can be expensive so make sure you have a lot of money for it.
If you also live in an older home that was not designed for duct work then you can also use the ductless air conditioner system to your advantage. In a similar way, if you originally had a smaller home but extended it and ignored the original house plan, it might not be good for a central AC so your best option is a ductless AC unit.
If you are not very pleased with a centralized air conditioning unit’s general cooling ability and you want certain parts of the house not too cold, you can opt for a ductless system. With the power of a ductless unit, you can control which parts of the house are cool and which can remain warm. This can have a good impact to your bill to reduce on spending too much electricity at home.
Aside from the ruined aesthetics, some ductless systems are also not very even when it comes down to both heating and cooling, as nothing can beat the even temperatures of a centralized duct work AC system. However, if this is not an issue for you and you just need something to control each and every room’s temperature to save up on expenses then a ductless system may be for you.
The main difference between the system and setup of an air conditioner that is ductless and one that is centralized is the fact that there is no ductwork on the ductless one and the air handler or evaporator doesn’t need to be placed inside the house or in a visible area of the house. This is why most people still stick to centralized ACs for aesthetic purposes.

How We Picked

For the best ductless air conditioner for your needs, you might need to consider the following factors first:
EER or SEER: from 14 to 20 SEER, you can get a ductless air conditioner that is best for your needs. The higher the SEER, the more energy efficient it will be for your home, office or living area.
BTU rating: from 12,000 to 20,000 BTUs, you can have a ductless air conditioner that best suits the cooling or heating area. Larger homes will need higher BTUs so they can be cooled easier in the least amount of time possible.

Other Frequently Asked Questions

Q: What is a ductless air conditioner?
A: A ductless air conditioner is simply a no duct work air conditioner system. Compared to the centralized air conditioner, the ductless AC unit can be set in different areas of the home without the need of duct work. This is essentially the best for homes with very limited space or lack of good design. Most homes can’t afford to go for duct work in achieving a full house air conditioner system.
This is why you can go ductless with a ductless air conditioner system, which essentially does the same thing as a window type but on a larger scale. The ductless AC sprays out refrigerant and can cool down all the parts of your house. Ductless systems are the best to use on older homes or if your house was initially planned small but you made extensions and got the design mixed up.
Q: Are ductless systems or mini split systems better than centralized AC units?
A: They are specifically better if we are talking about room size and house size. Centralized AC units are great for bigger homes but you can also experience the same kind of cooling effect if you install ductless AC units at home. The benefits of AC units that are ductless are great because you don’t have do to duct work to get them cooling.
If your house isn’t designed for duct work then you can opt for a mini split system or ductless system. Zone cooling is a thing nowadays because it is cost effective and also less of a hassle to install in most homes. Instead of hiring a HVAC expert, ductless systems can be easily installed with a DIY method.
Q: What cons can I face if I go for a ductless system?
A: While most ductless air conditioners are typically beneficial for most homes over a centralized AC or a window type AC unit, ductless systems are a newer technology and thus, can be expensive. This high expense is much like buying a solar panel or some LED lights that are pretty hefty over the traditional one in terms of price, but can reduce your electric bill.
Ductless systems are meant to reduce on operational costs and your energy bill, hence they may cost even more than other technologies of air conditioning. Many ductless systems are great when it comes down to the return savings, but you need to be prepared to pay an upfront price that can be quite shocking for most people.
Q: Are ductless air conditioners good at air filtering?
A: Yes, most ductless AC units today can improve the quality of your air. Most of these systems have better air filters and could be integrated with the newest HEPA filters so you get an air filter and an air conditioner in just one unit. This is an ideal AC unit to have if you have kids at home or someone who is prone to allergies.
One of the best reasons to get a ductless AC unit is due to the filter. The filter part of the ductless AC unit is usually strong against allergens, dust, pollen and other airborne particles such as bacteria and germs. The strength of this filter can potentially block out deadly diseases such as colds, cough and flu. It is also a great way to keep the pet dander out of the air.
Q: What optional systems can I put into my ductless AC unit?
A: To improve your ductless air conditioner on its performance and convenience, you can add a heat pump so you can also use it during the winter when you need sufficient heat at home. Single zone and multi zone condenser units can also maximize the cooling or heating capability of the ductless AC unit.
A ceiling cassette can also be a great option for homes with lack of space or area. Wall units act like centralized thermostats to help you set the room temperature for each room depending on your needs. All of these neat features may be incorporated with your ductless system so you can enjoy the benefits without a lot of hassle. While they can be an additional budget, you will get more convenience for cooling or heating all year round anyway.
Q: How much does it cost to have a ductless AC unit at home?
A: It depends on the size of your home but you will most likely spend from $3,000 to $5,000 because you need to purchase at least 3 units on the minimum, with one costing pretty hefty, and you may need the assistance of an HVAC contractor who is licensed. Although ductless AC units are ductless, they can still take some time in installation.
Q: Are ductless air conditioners quiet?
A: They are about as quiet as a central air conditioner system but they can be quieter due to the fact that they are made with better technology today. The purpose of a ductless AC unit system is to be an alternative solution to a centralized HVAC or AC system that requires a lot of duct work. While you still need an outdoor unit for ductless systems, they also run quietly like the duct systems.
One of the big advantages of ductless air conditioners is being quiet because the original motor is outdoors. This is similar to the quiet nature of the duct version of this AC unit system – the central air conditioner. However, the advantage is better in the ductless version because you have no ducts to manage and no large electric bill to worry about.
Q: Where is it best to install a ductless air conditioner system?
A: If you have very limited space at home and you do not have room for ducts around the house then you can install a ductless air conditioner system for your best needs. This is a best option for those living in apartments, dorms, condo units and the like where space is something precious to waste.
A ductless air conditioner system can fit well on most older homes or oddly designed homes that were not meant to take duct work, or where space is very limited and considered precious. Moreover, if you add a new room to the house or an extension, you can easily cool it with a ductless air conditioner system without having to do some duct work.
Q: Can you change the temperature of different rooms in a ductless system?
A: Yes, one of the great things to know about a ductless system is that it is not centralized, meaning you can keep one room warm but one room cold. Unlike in a centralized system where everything is cold, you can fine tune the house’s cooling depending on your needs to save up more energy in the long run.
The concept of a ductless system is similar to using a flexible cable service instead of a single cable box. If you have many televisions at home and the kids want to watch cartoons but you want to watch your late night show, the cable box might not work for you because it will simultaneously show the same channel on all your TVs. This is why ductless systems are preferred by most people today.
Q: Why are some people worried about the aesthetics of their home with a ductless system?
A: A ductless system for air conditioning uses refrigerant lines, which can be unattractive and can ruin the aesthetics of your home. In layman’s terms, they are messier in appearance than that of a centralized AC system. Think of it as having wired connections over wireless systems.
Q: What are the parts of a ductless air conditioner and how do they work?
A: The ductless AC is made up of roughly the same things as a central air conditioner, minus the duct work. They have a condenser or compressor outside, which is connected through a conduit or coil unit. This connection or refrigerant line connects to your evaporator or air handler, which then blows the cool air into your home.
Q: Can ductless ACs also have variable speeds?
A: Yes, to help you save up on energy further , you can set the right speed for your needs for the air handler of your ductless air conditioner unit. This makes it easier for you to set the right temperature without expending too much power and preventing a lot of costs on your monthly bill.
Variable speed inverters can be seen on most modern ACs today and is no surprise present in the ductless air conditioner system today. The variable speed function is important so that your motor will not suffer a lot and so that your monthly bill will not be too intense.
Q: Aside from the higher area in your wall, where else can you install a ductless air conditioner?
A: There are many ways for you to connect and install your ductless AC system. For example, you can use a recessed ceiling system to effectively blow cold air better around the house. If you want something more fashionable for your home, you can go for a horizontal version that is smaller. Floor mount units are also available.
The key to getting more cool air around your house even if you only have a ductless air conditioner is a strategic way of placing all of your units around the room. You can consult an HVAC specialist or knowledgeable interior designer to ask the best spots around the house to place your units onto to achieve the best cooling (or heating) possible.
Q: Can you convert the ductless air conditioner into a heater?
A: Yes, most ductless ACs today , as we mentioned above, can also be reversible into heaters. In this way, you can stay as warm as possible during the fall and winter without having to buy another heating unit or furnace.
The ductless system is essentially similar to the central air conditioner, but without the air ducts, such that it can also be converted into a heater for the winter time. The versatility of these units make them a great choice for homes that live in a four-season climate and need to adjust to year-round weather without compromising on health and budget.
Q: What is the inverter technology in air conditioners?
A: The inverter technology, also known as the DC inverter, is the latest in technology when it comes down to the construction of the motor of the air conditioners today. They not only make the AC unit run quieter but are also better when it comes to energy savings. Most ductless type of air conditioners are inverter type units as they are fairly new to the market.
Air conditioners that run on inverter technology can be more expensive, but you get the return of savings every month and a quieter motor as it operates in your home. Inverter technology is a great way to help the environment when you reduce on electricity costs. They are usually made with a microcontroller, which automatically adjust the temperature depending on its surroundings, which makes inverters the “smart” way of cooling your home.
Q: Who can use an inverter type air conditioner?
A: Anyone with a good budget and a need for all year round cooling might need an inverter type air conditioner. If you have a two-season climate then it might not be a necessity, but if you’re in a four-season climate country then having an inverter type unit is important to save up on costs for both cooling and heating, as most AC units can be converted into heaters as well.
Q: What is BTU and what is EER in terms of air conditioners?
A: BTU and EER stand for British Thermal Units and Energy Efficiency Ratio respectively. BTU is the way you measure the strength and capacity of an air conditioning unit in terms of converting hot air into cold air per hour. The average BTU for window type air conditioners is about 10,000 BTUs more or less.
EER is how you measure the energy efficiency of the air conditioner, and can range from 10 and above for most air conditioners. The variant, called SEER, is for larger units that are operated for the whole year, and may include heating capabilities. EER can be found on the air conditioner unit’s sticker.

EER Minimum of 10
SEER Minimum of 12

Q: How is SEER different from EER? What about HSPF?
A: SEER and HSPF are terms you will see on higher grade air conditioners, such as centralized and ductless systems that are typically for larger homes, establishments or commercial use.
SEER or Seasonal Energy Efficiency Ratio measures on variable temperatures instead of a fixed temperature, unlike with EER.
EER or energy efficiency ratio is only based on a fixed temperature instead of variable temperature.
HSPF or Heat Seasonal Performance Factor is for the heat pump function of the AC unit, if it is capable of having one.
Q: How does an air conditioner get Energy Star certified?
A: Energy Star certification is a means of certifying that a product is truly eco-friendly and can help consumers save up on energy costs. The consumer should be able to get return for their investment overtime due to the electricity savings from the air conditioner. These units might also be tested by the EPA (Environmental Protection Agency).
Q: How does a ductless system compare to a window type unit?
A: The ductless system is far more expensive than the window type air conditioner. However, the window type may consume more energy compared to the ductless system, which can help you save up energy and cool a lot of parts of the house simultaneously or one at a time, compared to the single room cooling of a window type AC.
