Written Adding a RegisterBest option would be to add an additional register and vent in the bedroom if the existing central heating and air can handle the load. If this would require upgrading to a large or additional unit, you may want to look at split units.Adding a Split UnitA split unit is made for this type of scenario. It works much like a conventional AC. The key difference is that there is no duct work. A small pipe and electrical connection run from a unit placed on your wall to the small condenser on the outside.The noise would be comparable to a small fan depending upon the model. Since the compressor \ condenser is located outside, this eliminates the main noise culprit.Portable Unit \ Window UnitAny portable unit regardless if it is a window unit or not is going to be extremely loud.Here is a little chart to give you an idea:Subway Station Platform                     100 dBWindow Air Conditioner                       50 dBSplit Unit(Based on Model)           21 - 36 dBConventional AC - New Register     8 - 12 dBOverall, most units, split and portable, list the noise level and you should look for this in the specifications before purchasing whatever solution you choose.

Written If your looking to install an air conditioner in a bedroom you basically have two options:1.  portable air conditioner that will cool the air in the room and expel the hot exhaust air out of a small opening that will sit in the window or vent through a hole in the wall.2. A window air conditioner that will attach to the window frame and cool the room by drawing outside air in, cooling it, then circulating it throughout the room.1995 honda civic ac compressor replacement///ai... there seem to be a couple models that are praised as being decently quiet. fry's portable ac unitI recommend using ctrl+f and searching the webpage for the word quiet, it turns up more than a few times.ac window unit repair san antonioWritten Looking for a quiet air conditioner for bedroom, the first principles of selection the best bedroom air conditioner still apply.

The bedroom air conditioner must be sufficiently large (in terms of BTU) to be able to cool the space of the size of your bedroom. Bedrooms get very hot too! Additional requirements for a bedroom air conditioner are the energy saving features such as sleep mode. The sleep mode will start by bringing the temperature of the bedroom to the desired level, then in a short amount of time, say about an hour, bring the temperature up by a few degrees, and then keep the temperature at that elevated level for 6-7 hours, supposedly while you sleep. The sleep mode will then bring the temperature down to the desired, original level, just in time to wake up.That way, the sleep mode will save you energy while letting you sleep at a higher temperature, which suits the body.I have investigated the quietest A/C units for bedrooms. In my research, Sharp CV2P10SX with its "Library Quiet" cooling, and Frigidaire FRA086AT7 come out as winners. See more about these here: http://3tonairconditioner.net/qu...Updated Sharp CV2-P10SX is a portable air conditioner marketed as being "library quiet" and, in fact, most buyers agree that it is quiet, even quieter than many window units.

It is therefore highly suitable for bedrooms of light sleepers. Check it out here: http://3tonairconditioner.net/qu... (disclosure: I contributed to this site)Save $20 Each When You Order 2 or More!

An air conditioner seems as if it cools your home's air, but in reality an air conditioner makes your home less warm by removing heat from the indoor air and transferring that heat to the outdoor air. Heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air.

The cooling cycle continues until the indoor temperature reaches the thermostat setting. Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers. A SEER rating (Seasonal Energy Efficiency Ratio) is an efficiency rating for air conditioners.  The higher the SEER rating, the less your unit will cost to operate.  National minimum standards for central air conditioners require a SEER of 9.7 and 10.0. But you do not need to settle for the minimum standard, there is a wide selection of units with SEERs reaching nearly 18. Before 1979, the SEERs of central air conditioners ranged from 4.5 to 8.0. Replacing a 1970s-era central air conditioner with a SEER of 6 with a new unit having a SEER of 12 will cut your air conditioning costs in half.

Generally, yes – central air conditioning systems are better (mechanically, functionally, and with respect to efficiency) than window units. However, it’s important to remember that “better” can be defined in many different ways. There are indeed some circumstances where a window unit might be the best option for your cooling needs. First and foremost, keep in mind that window units are intended primarily for cooling a single room (or area of a room). Window units are not intended to cool multiple rooms in the same building (or even an entire room if the room itself is large). If your goal is to cool a large area or multiple rooms, you should be considering your central air conditioning options, which may include ductless systems in addition to more traditional HVAC systems. Some people assume that today’s ductless systems really just represent an evolution of decades-old window units.

Like window units, ductless systems are also intended to cool only a limited space (such as one room or one portion of a room). However, ductless systems are much more efficient than window units and can be installed as zoned systems with multiple indoor wall units. Ductless systems will also be much quieter to the indoor ear versus window units. Aesthetically speaking, window units carry the obvious baggage of having a large plastic-and-metal box jammed into your window frame – they block your view of the great outdoors, and they block sunlight coming into the room as well. Additionally, window units are louder to building occupants because their compressor is located within the unit itself (not outdoors or in a separate location). There are some limited situations in which a window unit might be the best fit for your cooling needs, including situations where you’re only concerned about cooling one room or where you’d like to supplement other cooling systems in hard-to-cool areas like a four-seasons room or a spare room over a garage.

If you’re cooling multiple rooms and if the budget allows, central air conditioning is the more efficient, less costly-to-operate option to pursue. If you’re a typical homeowner, central air is the most cost effective, energy-efficient way to go. Additionally, central air is the lease intrusive and most aesthetically-pleasing home cooling option.
