Room air conditioners just got cheaper to run, thanks to stricter standards that require Energy Star models to use at least 15 percent less energy than the minimum allowed. That can save you about $90 over the life of the unit. And tougher standards will affect all models manufactured for next year’s cooling season. Meanwhile, Consumer Reports' new comfort tests show that this year’s best room air conditioners can help you chill more quickly and quietly right now. Our new tests now include how well the models cool the area they’re sized for. The small GE AEM05LS, a CR Best Buy at $210, and large LG LW1214ER, $350, aced those comfort tests. So did the GE AEM12AS, $390. But failure to restart itself after we reduced the voltage in our brownout test makes it a bad choice where power is iffy. Most of our picks, when set on low, were about as quiet as a dishwasher.

The Friedrich Kuhl SQ05N10B, $575, proved whisper quiet. It’s also the first room air conditioner we’ve tested that let’s you turn it on from your smart phone or tablet before you get home. The noisiest of the bunch was the GE AEM08LS, $270, but it had very good scores for comfort and is excellent in brownout conditions.what is the best ac unit brand Check the results of our latest air conditioner tests for a model that fits your needs. how much for a new ac unit installedBut don’t buy too big. outside ac unit replacementA smaller air conditioner that hums steadily along is more efficient and better at dehumidifying than a larger one that cycles on and off. Figure on 20 British thermal units (Btu) for each square foot you’re cooling and then factor in more if you have high ceilings, large doorways or windows, and if the room is in direct sunlight.

Here are recommendations from Energy Star on how to properly size an air conditioner. View and compare all Air conditioners ratings.There's nothing quite like the buzzing drone of an air conditioner. While it can help cool your home during a hot summer day, the noise of A/C can make for some sleepless nights if the unit sits too near your bedroom. The good news is that modern ones operate far more efficiently to help you save money and cool air faster. Many also feature low-noise technology. Quiet operation is a standard industry term to denote window and indoor, portable air conditioner that cool a room or home without a lot of noise. They are usually also labeled Energy Star for power efficiency. You'll also see terms like EER, or energy efficiency ratio, that compares the BTU cooling output to input electricity. Another term, SEER, looks at seasonal efficiency. It attempts tell you what you'll pay on average for a device over a season. More than any other factor, the type  determines the level of noise generation.

Many homeowners focus on initial price, operating cost, and efficiency, but noise levels also play an important role in the overall comfort of a home. Because the units themselves are in the attic, garage, or outdoors, central air conditioners reduce indoor noise levels simply by being located far away from living spaces. Side by side, central units are significantly louder than window or portable air conditioners, but the latter two are usually in close proximity to bedrooms or living rooms. Central air conditioners have two main pieces of equipment: an indoor furnace usually located in a garage or attic and an outdoor compressor unit. The compressor acts as a giant heatsink and fan, chilling coolant that runs to the furnace. Inside the furnace, air is blown over the coolant coils to drop the temperature, and then the chilled air is blown into the house. Besides being the most efficient type of air conditioner on the list, central air conditioners also help insulate the home by maintaining a closed system.

They do not require any holes in the walls between the inside and outside, and windows can remain closed, which would otherwise create gaps in a home's insulation. Inside, it barely makes any noise at all, and the outdoor compressor unit is audible only as a quiet hum through the exterior wall. Significantly cheaper than central AC, ductless air conditioners use smaller compressors and avoid ductwork with the furnace installed directly into the wall. Although they require less work and cost less money to operate, they generally don't provide enough cooling for an entire home. They can still cool a single room or even an entire story efficiently, but they generally require supplementary cooling in the form of window or portable air conditioners. Once again, most of the equipment is located outdoors, but the furnace does generate some noise in the wall, and the fan is also noisier than in a central A/C system. However, they are much easier to install, and they still retain most of the insulation benefits of a central air conditioner.

For homeowners on a budget or who have constraints in installing central air and heating systems, window air conditioners can't be beat. They cost just a fraction of the price and do not require expertise to install or remove during the winter. If it breaks, homeowners can simply purchase a new unit. If a central or ductless system breaks, it needs repairs, which could take considerably longer. Window air conditioners tend to be louder than their exterior counterparts because the entire unit sits in the window frame. Homeowners also tend to put them in rooms where they will provide the most benefit, including a bedroom. Even easier to install than window options, portable air conditioners sit on the floor and vent hot air outside through a window, usually through a hose or dual hose system. Window vents take up about 8 inches of window space instead of 18 to 24 inches for window units, and the portable unit itself is about the size of a standard dehumidifier. While installation is easy in any room, portable air conditioners cannot dehumidify efficiently because they cannot drip water outside like the other three types.

Many portable units contain a small reservoir, which vaporizes and humidifies the room. Portable air conditioners are also entirely located inside a building, and they receive no noise reduction from exterior walls. However, not all are noisy. Some are actually rated to operate beneath urban background noise levels, and they can be as quiet as ceiling fans. Other units may generate more noise but cool faster. Many companies have specific air conditioner lines targeted toward quiet operation. Sharp markets its Library Quiet portable air conditioners as being "as low as 38 dB at low cool" settings, or about as quiet as a standard refrigerator. Whynter sells devices like its 14,000 BTU portable dual hose air conditioner with heater that is designed to be quiet and energy efficient. Other models like a Haier air conditioner and heat pump include a remote for operation across the room. Many of these air conditioners trade some efficiency to achieve those low noise levels. Besides the type of air conditioner, homeowners have other choices to reduce unwanted noise.

From how an air conditioner is installed to its individual settings, each of these can save energy and money while preserving a quiet home. As a general rule, smaller air conditioners operate more quietly and cheaply than larger systems, but larger systems can cool air more quickly and efficiently. Smaller systems can reduce unwanted noise, but they can end up using more electricity per BTU than more efficient systems. The best air conditioners balance cost, noise, and efficiency without skimping on any of those concerns. The following chart recommends air conditioners based on the area's size: If there is sufficient cooling for the entire house, consider moving a window or portable air conditioner to another room and leaving the doors open to promote better air circulation. The walls will minimize or completely eliminate any noise between rooms, and there is no cost to move an air conditioner to another room. Good air circulation can also reduce noise by maintaining a uniform temperature throughout the house, which can help reduce an air conditioner's workload, allowing it to switch to a lower setting or turn off completely.

Air circulation can also reduce humidity and musty odors that can develop in closed off rooms. Air conditioners aren't the only appliances that maintain a comfortable temperature. By supplementing air conditioners with these other devices, homeowners can reduce humidity, improve air circulation, and save energy. Ceiling fans don't really cool air, but they do move it around, which makes air feel cooler than it actually is. Even though ceiling fans provide little more than a gentle breeze, it's enough of a wind chill factor to make room temperature feel several degrees cooler. They're also relatively easy to install, and they're inexpensive to both purchase and operate. Ceiling fans create almost no noise and cannot be heard over the hum of a computer or television. Dehumidifiers actually produce a tiny amount of heat, but they remove humidity from the air, which also makes air feel cooler. Dropping a room's relative humidity by 20 percent can make it feel 2 to 3 degrees cooler, thereby allowing homeowners to turn their thermostats up while maintaining the same relative temperature.

Dehumidifiers produce less noise than portable air conditioners, consume less electricity, and can be placed anywhere in a house. They don't need to be located in a particular room because a building's humidity remains uniform with adequate air circulation. The last way to reduce noise is to adjust an air conditioner's settings. If a room or home is already at the target temperature, consider turning the fan speed from high to low. The auto fan setting even turns the fan off if the temperature drops to a predetermined degree, which eliminates any noise and power consumption from the air conditioner. Turning a thermostat up also reduces noise and save money. For every degree, an air conditioner reduces its power consumption by 5 to 10 percent, which allows it to run at lower power settings more frequently. Lower power settings produce less noise. A programmable thermostat can automatically adjust the temperature on a schedule, turning the temperature up when everyone's at school or work and cooling the house down when everyone comes home in the evening.
