Mini-Split Air Conditioners FAQs 

How do I choose a ductless mini split air conditioner? 
Like all air conditioners you need to know how many BTUs you need to cool the area you are trying to cool. You also need to consider the number of air handles that you need normally one air handler per room is what you would need but, if your home has open areas you may be able to cool multiple rooms. 

There are many options for types of air vents that you can purchase some sit in the home and are mounted on the walls and some can be mounted in the ceiling. It is important that you talk to a person who is certified to install air conditioning about your options to help you decide which would meet your needs. 


What are the pros and cons of a ductless mini split air conditioner? 
Ductless Mini split air conditioners is a cost effective choice to center air conditioning. They are typically more expensive than wall or window air conditioners and you need an HVAC professional to install the unit. Since the compressor sits outside they mini split air conditioners are very quiet and efficient. 



How do I install a ductless mini split air conditioner, why do I need a HVAC Professional? 
Install a Ductless mini split air conditioner is more complicated that a window unit but far less complicated than installing central air. A professional will need to run lines for the coolant, electricity, and drainage. You will also need a professional HVAC person to charge it with the right amount of coolants. 


How big will the hole be in my wall? 
This slightly varies depending on the unit you buy but, it is generally 2-3/4" to 3" in diameter. 


Do I need to purchase tubing? 
Yes, you do need to purchase tubing to install your ductless mini split air conditioner. This is what will connect the indoor and outdoor units. The size of the tubing depends on how far the inside unit is going to be from the outdoor unit. 


Do some ductless mini split air conditioners have heat? 
Some through the ductless mini split air conditioners have electric heat strips and a few have heat pumps for more information on the heating options go here. 


What is ductless dual zone and triple zone? 
Dual zone means that there are two air handlers and triple zone means there are three air handlers. It is best to get an air handler for each room you are trying to cool but, if you are trying to cool open areas that consist of more than one room you may be able to use one air handler just make sure the BTUs are enough to cover the square foot area of all of the rooms. 


General Air Conditioner FAQs 
What is the difference between manual and electronic controls? 
Basically, this is as simple as a digital display for knobs. Keep in mind that you must have electronic (digital) controls to use a remote control. 


Could you explain the difference from between electric heat and a heat pump? 
When a unit says that there is electric heat there is a heat strip in the unit that uses the fan to distribute the heat. Electric heat is meant to subsidies an existing heat source. 

A ductless heat pump function is similar to an air conditioner however instead of cooling the air like it would in the summer it heats the air and redistributes it into the room. It often will not work when it is colder than 40 (except some PTAC units) degrees outside but, most unit have electric heat backup. If heat is very important to you a PTAC unit could be your best choice. Please look at the air conditioner description or call an ductless air conditioning expert. 


What does Energy Star mean? 
Energy star is a government backed program that backs products that are extraordinarily energy efficient. Products that meet strict energy efficient requirements determined by the EPA and the US Department of Energy that do not compromise the performance and features of a product receive the Energy Star logo. 


What are EER and SEER Ratings? 
The Energy Efficiently Rating (EER) is determined by The ductless Air Conditioning and Refrigeration that equals the ration of cooling capacity in BTUs to the power input in watts. This rating determines the state of the air conditioner when it is up and running. 
Seasonal Energy Efficiency Rating (SEER) is commonly used to measure central and ductless air conditioning. All air conditioners must have a SEER rating of at least 10 to be sold in the United States. 


What is a chassis and do I want one that slides out? 
A chassis is the guts of an air conditioner. When the ductless air conditioner is described as fixed that means that the chassis does not slide out. Air conditioners with slide out chassis are easier to repair especially if the air conditioner is a through the wall air conditioner. 


How do I determine the noise level? 
All air conditioners will make some sort of noise however the air conditioners on the market have been engineered to be quieter than older units. Mini split air conditioners are the most quiet since the compressor sits outside. 


What are air flow and output options? 
This determines how you can move the vents to determine where the air flows in your room. Air deflection means that you can move the vents to the side and up and down manually. Air swing means that the vents move electronically? 


What are fan settings? 
Air conditioners come with many levels of setting some just come with two settings (on and off) or with more like low, medium, and high. 

How do I determine my plug type or how many volts I need? 
Your plug type will let you know how many volts you need. You can look here to compare your outlet to see how many volts you need and also what type of plug your air conditioner requires.

Mini Splits have come as something a bit different from the already existing air conditioning systems in that they are ductless. They don’t require much space because they are not that bulky and in addition to that they are not as expensive as the other air conditioning systems. They are also really easy to install and give a new design and sense of attraction to your house.


The traditional air conditions have a total of two units; one inside and the other outside, both of these units work together to cool the air and force it through the duct system. In contrast mini splits have multiple units that work together to cool the house. Instead of ducts mini splits have refrigerant lines that run through a single unit that’s outside to each of the additional units inside. The refrigerant lines have got to cool the air and the inside units are meant to distribute this cool air throughout the house. Some of the houses require only one unit while the others which are larger may require up to 3 or more to cool the entire house.


It makes the overall cost of the mini splits to be far less cheap as compared to the central air conditioning systems. The absence of the ducts and presence of the refrigerant lines make the mini splits very economical. While the traditional air conditioning systems which use ducts make it really uneconomical because when the cool air passes through the massive duct system much of the cool air is lost while going towards the register of a particular room. In mini splits the cool air travels through very efficient lines directly towards the target. This makes them not only cheaper to install but also cheaper to easily pay off the electricity bills too.


If your home does not have the facility of providing you chilled air inside then you need only to take a little more investigation of the minisplits and have your solution for the problems of the summer heat. These would not only be easy to afford but also they are going to add style to your house.


One of the greatest achievements of science is perhaps the introduction of air conditioners which prove to be more useful then anything else in hot climatic conditions. The first air conditioners introduced were the window air conditioners which were really noisy and covered a large space. As the world is moving towards a new aspect of advancements ever made in the field of science and technology we are being introduced towards new and extraordinary things too. And there came the central air conditioning systems. But doesn’t it sound great to have a better substitute for something that’s already amazing? Mini Splits have come as one such great achievement and added more comfort and luxury to our already great world.

Some of the good features of mini splits are that they don’t have any security problems, they don’t produce a lot of noise, they require less space and you don’t need to make holes in the walls and windows in order to install them. There are no energy losses so they are really very economical.

Working collegially at a meeting dubbed the "Awareness Summit," they are exploring the messages and delivery mechanisms by which the HVACR industry can raise its profile in positive ways with target groups. We have an extraordinary message of achievement. And, new and better ways are evolving to provide more comfort and improved health from more efficient equipment operating at lower cost in harmony with the environment. 

It's cool to care about our customers and the environment and we do. There will never be a better time to build on our message of accomplishment with an industry-wide campaign that reminds the world of how our equipment improves the quality of life.

Thanks to comfort cooling, electronic equipment throughout the historic stock exchange building flashed data that detailed trading of more than a billion shares on August 9. Cable and TV broadcasts brought the bell closing scene to millions of offices and homes, and within minutes a picture of the event was on the Web site of the Air-Conditioning and Refrigeration Institute at www.ari.org. 

Fortuitously, the Dow Jones Industrial Average was up for a fourth straight day. There was happiness on the floor and among the 11 industry representatives as we celebrated shipment of the 130 millionth central air conditioner since the founding of ARI in 1953. 

An estimated - and astounding - 139 million people viewed The Closing BellTM when representatives of the HVACR industry recently ended the trading day at the New York Stock Exchange while standing on a podium before a banner that proclaimed "Air Conditioning and Refrigeration Appreciation Days." 

Looking down from 20 feet above the floor of the Exchange at hundreds of traders cheering The Closing Bell prompted thoughts about how things have changed since approximately a century ago when the Exchange became one of the first major institutions in American to install air conditioning and only a few hundred people would have viewed the closing.

But what would be the mood in the trading room and how long could heat-sensitive computers function without conditioned air? What would happen to telecommunications equipment without humidity control? How could computer chips be perfected without clean rooms? What would be the impact on productivity if the clock was turned back to the days when temperatures in the 90s emptied offices and factories? How would food and medicine safety and supply be affected without modern refrigeration and refrigerated transport? 

Thanks to an infrastructure built up over decades - and the innovative contributions of men and women in our industry who care about improving the quality of life - people live, work and play in a vastly different world from a century ago. 

From a novelty for moviegoers at theaters in the 1920s to modern-day, high-tech manufacturers' clean rooms, glass skyscrapers and malls, air conditioning is a defining technology. It has transformed America and many parts of the world. 

Yet our contributions are largely taken for granted. With air conditioning available to 83 percent of American households, it is becoming almost as common as water and electricity. You only miss it when the electricity goes off or the unit dies of old age. 

I believe the industry would sell more equipment if specifiers, building owners and consumers better appreciated our products, and also the people responsible for manufacture, sales, distribution, installation and maintenance of the equipment. 

The New York Stock Exchange Closing Bell ceremony was fledgling step toward elevating awareness about the industry. But a meeting in Chicago last month by an industry-wide group of manufacturers and contractors may have more lasting impact. 

Mini Split Air conditioners employ the same operating principles and basic components as your home refrigerator. Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings of your home; likewise, an air conditioner uses energy to transfer heat from the interior of your home to the relatively warm outside environment.
 
A Mini Split Air conditioners cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.
 
A heat pump, called the compressor, moves a heat transfer fluid (or refrigerant) between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils.
 
The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling your home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser's metal tubing and fins.
 
Throughout the second half of the 20th century, nearly all Mini Split Air conditioners used chlorofluorocarbons (CFCs) as their refrigerant, but because these chemicals are damaging to Earth's ozone layer, CFC production stopped in the United States in 1995. Nearly all Mini Split Air conditioners systems now employ halogenated chlorofluorocarbons (HCFCs) as a refrigerant, but these are also being gradually phased out, with most production and importing stopped by 2020 and all production and importing stopped by 2030.
 
Production and importing of today's main refrigerant for home Mini Split Air conditioners, HCFC-22 (also called R-22), will begin to be phased out in 2010 and will stop entirely by 2020. However, HCFC-22 is expected to be available for many years as it is recovered from old systems that are taken out of service. As these refrigerants are phased out, ozone-safe hydrofluorocarbons (HFCs) are expected to dominate the market, as well as alternative refrigerants such as ammonia.

Ductless Mini Split Air conditioners heat pumps (minisplits) make good retrofit add-ons to houses with non-ducted heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions, where extending or installing distribution ductwork is not feasible.
 
Like standard Mini Split Air conditioner heat pumps, mini splits have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units.
 
The main advantages of Mini Split Air conditioners are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated). Since each of the zones will have its own thermostat, you only need to condition that place when someone is there. This will save energy and money.
 
Ductless Mini Split Air conditioners systems are also often easier to install than other types of space mini air conditioning systems. For example, the hook-up between the outdoor and indoor units generally requires only a three-inch hole through a wall for the conduit. Also, most manufacturers of this type of system can provide a variety of lengths of connecting conduits. If necessary, you can locate the outdoor unit as far away as 50 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a building house with the compressor in a more advantageous or inconspicuous place on the outside of the building.
 
Since Mini Split Air conditioners have no ducts, they avoid the energy losses associated with ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.
 
In comparison to other air conditioning systems, Mini Split Air conditioners offer more flexibility in interior design options. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Floor-standing models are also available. Most indoor units have profiles of about seven inches deep and usually come with sleek, high tech-looking jackets. Many also offer a remote control to make it easier to turn the system on and off when it's positioned high on a wall or suspended from a ceiling.
 
Mini Split Air conditioner systems can also help to keep your home safer since there is only a small hole in the wall. Through-the-wall and window mounted room air conditioners can provide an easy entrance for intruders.

A new type of heat pump for residential systems is the absorption heat pump, also called a gas-fired heat pump. Absorption heat pumps use heat as their energy source, and can be driven with a wide variety of heat sources

Mini split Air Conditioners have two main components: an outdoor unit containing compressor and condenser, and an indoor air-handling unit, containing evaporator and blower. A conduit, which houses the power cable, refrigerant tubing and condensate drain, links the outdoor and indoor units. Ductless mini split air-conditioners have numerous potential applications and advantages. They are perfect for those home/business owners that do not have central air conditioning, and do not want to settle for the noise, insecurity and inefficiency of window AC units.

Ductless mini split air conditioning offer higher efficiency and reduced noise without a large hole in the wall or an open window. By separating compressor and condenser fan from indoor blower, the noisiest components are outside and away from the room. The indoor part of the ductless air conditioner has remote control capabilities and a timer to cycle the system only when needed. 

Since mini split air conditioner have no ducts, they avoid energy losses associated with ductwork of central forced air AC systems. Duct losses can account for a significant portion of energy consumption for space conditioning, especially if the ducts are in a unconditioned space such as an attic. 

Ductless air conditioning offers Higher Efficiency vs. window air conditioning, less noise, and no costly ductwork.

During normal thermostat cycle operation, cooling and heating operations automatically change in accordance with set temperature, time and room temperature. (Heat Pump unit only) 

Night Setback Mode for Cooling and Heating 
Cooling and DRY Mode: With the Night Setback Mode, the air conditioner automatically raises the setting temperature 2?F after 30 minutes, and then another 2?F after the next 30 minutes. 

Heating Mode: With the Night Setback Mode, the setting temperature is automatically lowered 4?F after 30 minutes. This saves energy without sacrificing comfort and is ideal for gentle cooling and heating. 

Ductless Split Air Conditioner / Mini Split Air conditioners Heat Pump products offer wide versatility in solving your cooling and heating requirements. The Indoor unit (evaporator) is mounted inside the room, enclosed in a handsome space saving cabinet. It is connected to the outdoor unit (condenser) via refrigerant lines & inter-unit wiring through a 3 1/2" opening in the wall. Since no ductwork is required, installation is simple. fast & efficient. There is no need to use up window space or cut large openings in existing walls, which could undermine the integrity of your structure, and even pose security risks. Since the Rotary compressor is located in the outdoor unit, compressor operating noise is virtually eliminated from the indoor. The indoor unit has been uniquely designed to provide Whisper Quiet operation while delivering comfort throughout the room(s). In addition, rotary compressors provide efficient, powerful cooling at the lowest noise levels in the industry.

For climates with moderate heating and cooling needs, Mini Split Air conditioner & heat pumps offer an energy efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space into a warm, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house; during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide up to 4 times the amount of energy they consume.
 
The most common type of mini split air conditioner heat pump is the air source heat pump, which transfers heat between your house and the outside air. If you heat with electricity, a heat pump can trim the amount of electricity you use for heating by as much as 30% - 40%. High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months. However, the efficiency of most Mini Split Air conditioner heat pumps as a heat source drops dramatically at low temperatures, generally making them unsuitable for cold climates, although there are systems that can overcome that problem.
 
For homes without ducts, Mini Split Air conditioners heat pumps are also available in a ductless version called a mini split heat pump. In addition, a special type of air source heat pump called a "reverse cycle chiller" generates hot and cold water rather than air, allowing it to be used with radiant floor heating systems in heating mode.
 
Higher efficiencies are achieved with geothermal (ground-source or water-source) heat pumps, which transfer heat between your house and the ground or a nearby water source. Although they cost more to install, geothermal heat pumps have low operating costs because they take advantage of relatively constant ground or water temperatures. However, the installation depends on the size of your lot, the subsoil and landscape. Ground-source or water-source heat pumps can be used in more extreme climatic conditions than air-source heat pumps, and customer satisfaction with the systems is very high.
