A simple reconfiguration of conventional central air conditioners eliminates the need for complicated ductwork and reduces energy inefficiencies caused by moving air through ductwork.

Because each room can be controlled by a separate thermostat or hand-held remote, temperatures can be customized for each room or zone to provide ideal heating or cooling anywhere it is needed. LG Duct-Free Split systems can usually be installed in less than a day by professional contractors. There are a wide variety of that come with duct-free technology. With over 65 years of air conditioning experience, you can be assured of high-quality, long-lasting products for your home from LG. samsung window air conditioner thermostatSee a in action.high seer window ac units Duct-Free Split systems, also known as split, ductless, ductless mini split, or mini splits, are simply a reconfiguration of a conventional central air conditioner.jual ac portable bekas surabaya

They provide greater temperature control since each indoor unit works independently and can be set to different temperatures—allowing you to cool certain parts of your home without cooling the entire space.

This zone cooling helps decrease energy usage since you're only cooling parts your home that you actually use as opposed to cooling your entire home like a central air conditioner. For quick access to the sections in this buying guide, click the links below: Ductless systems are made up of 4 components: Mini-splits have distinct advantages over other room air conditioners: A single-zone ductless split system cools an area of your home using 1 outdoor and 1 indoor unit. These are popular in bedrooms or rooms that aren't ducted for central air conditioning. The main consideration with single-zone ACs is if the unit has enough power to cover your room's square footage. View single zone ductless mini splits. Multi-zone mini splits work just like single-zone models but cool more parts of your home or business. Each indoor unit (representing a zone) connects to the outdoor unit through the refrigerant lines. There are generally up to 4 indoor zones. If you don’t have central air conditioning, consider using a multi-zone system to cool different areas of your home—which can be on multiple floor levels thanks to long refrigerant lines.

Multi-zone models are popular in basements, doctor's offices, and apartments. The single outdoor unit is equipped to handle all interior units, though usually all can't be used on the highest level at the same time. View multi-zone ductless mini splits. Each indoor ductless unit offers a set number of BTUs of cooling power. For single-zone units, you simply need to know the number of BTUs associated with the indoor unit and make sure it fits the square footage you're cooling. For multiple zone systems, both the outdoor and indoor units have a BTU rating attached to them. One benefit of a ductless split system is each indoor unit runs independently. Keep in mind if you're purchasing a multi-zone system, you need to look at the BTU rating for each unit (or zone). For example, an AC may use 30,000 BTUs total, with each indoor unit using 9,000 BTUs and the outside unit using 12,000 BTUs. Check out our square footage and BTU comparison chart below. Installing mini split ACs require professional installation since you run the refrigerant lines indoors from outside your home through a small hole in your wall.

You'll need to contact an HVAC professional to be sure your AC is installed to run as effectively and efficiently as possible. Indoor Unit Location Options Most indoor air conditioning units are hung on a wall using included brackets, while other models are hung from the ceiling. Be sure your refrigerant lines will reach each indoor hanging unit before you install them. Check where your indoor units can be installed before you purchase a mini split AC. Voltage is another important consideration for your ductless mini split's insatllation. Smaller-powered mini splits use a standard 110- to 120-volt plug, which most homes are wired for, but larger units require higher voltage. These models use a 220- to 240-volt plug; make sure your home's voltage matches your unit's before purchasing. Using the incorrect voltage can cause the circuit to break, a loss of efficiency, or even cause a fire. Mini split systems are efficient ways to cool your home. Their efficiency is measured by a Seasonal Energy Efficiency Ratio (SEER).

The higher the SEER, the more efficient the unit. Currently, federal requirements state mini splits must have a 13.0 SEER rating to be used in the United States. Another energy rating to look out for is Energy Efficiency Ratio (EER), which looks at energy usage per square foot of cooling. SEER and EER both rate your product's efficiency, so keep an eye out for one or the other when comparing products. Along with SEER (and possibly EER) ratings, your model should come with an estimated yearly operating cost. This is an average dollar amount associated with your model based on operating and maintenance costs—if you're comparing 2 models, check out the estimated yearly cost before purchasing. If a model is extremely efficient, it can become Energy Star-rated. In order to become Energy Star-rated, models must prove to significantly contribute to energy savings and offers products and performance demanded by consumers. Replacing an inefficient cooling system with a mini-split can cut your heating and cooling costs by up to 30%.

The outdoor unit is the compressor, and it's one of the most important parts of a mini-split AC. The 2 main compressor types for mini splits are inverter and rotary. A rotary compressor turns on and off while working to maintain your set temperature, while an inverter compressor uses only enough power to reach the desired setting, then idles at that setting until more power is needed. A rotary compressor will turn on with full power, while an inverter compressor only uses enough of its resources to reduce the room temperature to your desired setting. Many people prefer inverter compressors because they save energy by not constantly turning on and off. Most new ductless mini splits use inverter compressors. Mini splits can include multiple modes to keep your home full of crisp, cool air in the summer and warm air in the winter. Additional modes are popular for people who don’t have central air conditioners and use their mini-split AC as their primary cooling option. Keep an eye out for these modes for year-round comfort:
