  • How Does Ductless Air Conditioning Work?
  • As the name implies, ductless air conditioning systems are those that do not rely on ductwork to deliver cool air. A ductless air conditioning system consists of two major parts: a small indoor air delivery unit and a larger outdoor compressor unit. On the inside of a room, the indoor component is installed near the ceiling on an exterior wall. Holes must be made through the wall to the outside, and refrigerant lines must be fed through these holes. The refrigerant lines connect to the outdoor compressor, which typically sits on a level concrete slab on the ground. The outdoor compressor is connected to a source of electricity. Top ?
  • Explain Ductless Air Conditioning Cooling Process
  • When a ductless air conditioning system is turned on, the compressor and refrigerant stored in the outdoor unit begin working together to create cool air. Cooled air and electricity are then pumped out of the outdoor unit, along a series of refrigerant lines, into the indoor unit. The electricity delivered to the indoor unit powers a fan, which blows and distributes the cooled air throughout the room in which the system is installed. Hot air inside the room is also pumped out through the indoor units and refrigerant lines, as well as condensation that collects inside the indoor unit because of the cool air. Top ?
  • What are Advantages of Ductless Air Conditioning?
  • Ductless air conditioning offers the best balance of efficiency, cooling power and value for homes that do not have existing ductwork. Many homes built before the development of central climate control were built with thinner walls that cannot accommodate standard ducts. For these homes, there are four air conditioning options; ductwork can be built into the interiors at the expense of living space and décor, flexible pipes can be installed in the walls in place of ducts, window air conditioner units can be used or ductless air conditioners can be installed. Ductless air conditioners are far more powerful, secure and energy efficient that most window units and are far cheaper and easier to install than in-room ductwork or pipe-based central air conditioning. Top ?
  • What are components of Ductless Split System?
  • A ductless air conditioning system takes up very little room inside your home. It is referred to as mini split or a ductless split system because it consists of two components:

    • A compressor unit that is installed outside your home on a concrete slab
    • An indoor unit that contains a fan, which is installed near the ceiling on an exterior wall in the area to be cooled

    Copper refrigerant lines connect the two units through holes that are drilled and run through the wall. Electricity is supplied to the indoor unit from the outdoor unit, so no additional wiring is need in that room. Top ?
  • How the Room is Cooled?
  • Once the ductless air conditioner is turned on, it works pretty much in the same way a regular central air system would work. The only exception is that it works without the ductwork and additional equipment that would be installed in the home for central air.

    The outdoor compressor unit pumps and cools the system’s refrigerant through the copper lines to the indoor unit. The fan inside the unit turns and distributes the cool air throughout the air. Cool air is heavier than warm air, therefore the cooled air drops, while the warmer air rises.

    The warm air is retrieved through the indoor unit and removed along with condensation that may have collected inside the unit back out to the compressor through the copper lines. Top ?
  • What is installation cost of Ductless Air Conditioner?
  • Depending on the size of the home, installation costs for a complete system range from around $2,000 to $7,000. This cost is roughly double that of installing a window system, and roughly 30% more than a central system, if your house already has ducts. For a home that lacks ductwork or the space to install ducts, it is less expensive to install a ductless air conditioning system than central air conditioning. Top ?
  • How to Size Ductless Heat Pumps
  • A ductless heat pump, or mini-split heat pump, is the appliance of choice when it comes to conditioning an addition to your house, according to Christian Smith, an HVAC contractor. Installation is relatively simple and the cost of material is low, since there is no duct involved and you don't need to change the existing HVAC system. Another advantage, according to Smith, is the ability to control the temperature in the room addition separately from the rest of the house. This makes it perfect for a sun room in which temperatures fluctuate more than most

    Instructions:
    • Measure the length and width of the room in which you are installing the ductless heat pump. Write these figures on your pad.
    • Calculate the square footage of the room by multiplying the length by the width.
    • Multiply the square footage by 20. This number is the BTU rating of the ductless heat pump you need.
    • Choose the ductless heat pump you need. The numbers will not match exactly. For example, if you need 20,000 BTUs, then you will use a 24,000-BTU unit. Always round up in size.

  • How to Clean Home Ducts and Vents?
  • Over time the air ducts in a home build up with dust, debris and mold. Removing these contaminants provides your home with cleaner air and make your heating and cooling systems run more efficiently. This job is best left to a professional service who has the necessary equipment.

    Instructions:
    • Cut two access panels-one in the main supply and one in the main return line near the furnace.
    • Attach a high-powered and specially-made vacuum system to these holes.
    • Seal all vents in the home then power up the vacuum to create negative pressure in the duct system.
    • Open each vent, one at a time to access its ductwork. Clean debris from all the ductwork back to the furnace using long hoses and air-powered tools. Then re-seal the vent. Repeat this process with every vent in the house.
    • Access and clean the blower and its motor, the cooling coil and combustion components.
    • Remove the vacuum and re-seal the holes created in Step 1.

  • What Is a Ductless Heat Pump?
  • A ductless heat pump is a dual heating and cooling system that functions without the use of ducts. Japan first developed the ductless heat pump in the 1970s. Since then, much of Europe, Asia and commercial enterprises in the United States have used them.

    Components
    Ductless heat pumps have three or more components: an outdoor compressor unit, a refrigerant line and "heads." Each "head," or air-handling unit, is fitted high on a wall in each zone to be separately heated and cooled. The refrigerant line is run to the outside compressor from the back of each "head."

    Uses
    Ductless heat pumps are used in rooms where heat and cooling systems are not present, or as a supplement system to traditional units. A new room addition or three-season porches, without duct work, are example applications.

    Benefits
    Installation is uncomplicated and much quicker than traditional heating systems requiring duct work. Ductless heat pumps also provide air-conditioning and can save up to 50 percent on your home energy bill. They are also a safer alternative to portable heaters and consume less electricity. Top ?
  • Ductless air conditioners save energy tips?
  • In addition to the energy saving benefits provided by zoning, ductless air conditioners can circumvent all the energy losses associated with leaking ductwork. Losses from ductwork are some of the primary causes of inefficiency with central air conditioners, sometimes accounting for more than 30% of energy consumption – especially if ducts are in an unconditioned space such as the attic. Top ?
  • Do Ductless air conditioners are make noises?
  • With ductless air conditioners, all the noises that you may be used to from central air conditioners firing up and blowing air through your house are eliminated! The noisy parts of a ductless air conditioner, the compressor and the condenser, are housed as a single unit that is located outside in the backyard. This leaves the all but silent fan and evaporator units inside. Top ?
  • Are ductless systems efficient?
  • Yes! Ductless systems operate using 25% to 50% less energy than electric resistance and forced air systems. Three key factors account for the high efficiency of a ductless system:

    1. Ductless systems allow the user to control each heating/cooling zone independently, eliminating the costly over-heating and cooling common to central air systems. Why pay to heat or cool rooms that are not currently occupied?

    2. While central air systems lose as much as 30% efficiency through air leaks and conduction in the ductwork, ductless systems distribute air directly to each zone, resulting in 25% greater efficiency. Ductless systems use inverter-driven, variable speed compressors that allow the system to maintain constant indoor temperatures by running continuously at higher or lower speeds. Thus, the system can ramp-up or down without great losses in operating efficiency, avoiding the energy intensive on/off cycling common in electric resistance and forced air systems.

    3. Modern ductless systems have ultra-high Seasonal Energy Efficiency Ratios (SEER) between 16 and 22, and Heating Seasonal Performance Factors (HSPF) between 8.5 and 11.

  • How long have ductless systems been around?
  • Ductless heating and cooling systems were developed in Japan in the 1970’s and have since become a preferred heating and cooling system throughout Asia and much of Europe. In the United States ductless systems have been used in commercial applications for over 20 years. Top ?
  • How long will a ductless system last?
  • With proper maintenance and care a ductless systems should perform for over 20 years. Many of the systems installed during the 1980’s are still functioning well today. Top ?
  • How often does an Air Conditioner need Freon or Puron?
  • If your air conditioner doesn't seem to be performing well, you may be thinking about the need for more refrigerant. While you might be mechanically inclined, it's important to realize that there are many regulations and issues involving refrigerants. It's important to use the correct product for your system. Furthermore, most suppliers of HVAC refrigerants will only sell to licensed repair contractors. It's best to contact a properly licensed company to provide the necessary AC service. Top ?
  • How thermostat can play a great role in air conditioning maintenance?
  • The more your AC runs, the more strain is put on the system. If you work during the day, you should set your thermostat at a higher temperature so that your AC will not run as much while you are gone. You can lower the temperature as soon as you get home. This reduces overall strain and AC use and also results in a lower energy bill at the end of the month. If you have a window unit, you should turn it off when you leave home since window units typically use more energy than outdoor units meant to cool entire homes. A window unit will cool a room in little to no time at all, so you won't have to sacrifice much in terms of comfort by simply shutting yours off when you are not around. To keep your home cooler while you are gone, close your curtains or blinds to block out the sun.

    Many thermostats now come equipped with innovative technology that will allow you to program your thermostat to fit your exact needs. If you are lucky enough to have one of these in your home, use it to your advantage to optimize your system's usage and maximize its life over the long run. Top ?

  • Ductless air conditioner maintenance?
    • The air filter should be cleaned regularly. Air filters are usually very easily accessible. You can replace them or wash them if they are washable. Manufacturers recommend this should be done every 1-3 months during the season.
    • You can also spray the outdoor unit. Make sure to shut the power to the outdoor unit off. You can spray it with a garden hose and use a gentle brush to clean the coils. In case you bend some of the fins on the condensing coil, just use a flat screwdriver to straighten it out.
    • Make sure all the electrical connections are tightened and there are no signs of electrical cable overheating. Any discoloration may be a sign of a wire or a cable overheating.
    • Examine the run capacitor(s) for signs of deforming or leaking. If they are bulging or leaking they should be replaced.
    • Make sure there are no refrigerant leaks. In case of leaks, the place will be oily and dirty. It is usually a simple matter of tightening the connections. Be careful not to over torque them or bend the lines.
    • You can use a soapy water solution to check for leaks. Put the solution on the location and see if small air bubbles form. If no bubbles form, the system can be recharged.
    • You should also check the drain hose to make sure it is not clogged. You can complete your ductless ac maintenance by restoring power to the unit and observing a cooling or heating cycle.
