中央空调的选择和安装

• 如果你的空调需要持续运行, 昂贵的修理, 或者超过15年, 你应该考虑买个新的. A new higher-efficiency unit, when properly sized and installed, will cost less to operate.
• 如果你想降低运营成本, look for an A/C that has a high Seasonal 能源 Efficiency Ratio (SEER). A/C payback periods for homes can be very long in our service area, due to our short summers.
• Buying the correct-sized unit and installing it properly is critical to efficiency and comfort. 中央A / Cs must be sized, installed and set up by a licensed HVAC contractor.
• 为了最高的效率, consider purchasing an A/C with variable-speed motors for the outdoor fan and compressor as well as the indoor air handler. These variable-capacity A/Cs are the most efficient available and can also provide increased comfort with reduced noise. These systems are usually more expensive and have lengthy payback periods due to our short summers.
• 请专业人士检查你的管道系统. 漏水的, uninsulated or broken duct systems are common and reduce the effectiveness of your central A/C and heating system.

A / C维护

• 在降温季节定期检查系统的过滤器. 根据需要更换(或清洁，如果可重复使用). Dirty filters block normal airflow and significantly reduce a system’s efficiency and life.
• If you are experiencing a problem, have your A/C professionally serviced. 要求进行一次调整，包括检查制冷剂充注量, 清理盘管，检查你的管道系统.

日常空调提示

• 不要为了让房子更快地降温而把温度调低. 它不会更快地冷却你的家.
• 检查你的恒温器设置. 大多数人可以在74-78度之间感到舒适.
• Consider installing a programmable thermostat to allow automatic adjustments for higher temperatures at night and when you are away without sacrificing comfort when you need it.
• Weather strip doors and caulk windows to prevent losing cool air to the outside and warm air from coming in.
• Make sure there’s sufficient insulation throughout your home to help keep the heat out.

窗房空调的选择与安装

• 购买能源之星认证的设备. ENERGY STAR certified window room air conditioners use at least 10% less energy than models built to current minimum-mandated efficiencies and significantly less than older models.
• 为了实现最佳运行, install the unit in a north-facing window of the room you would like to cool, 或者在阴影区.
• 考虑一个带有控件的单元, such as a digital readout for the thermostat setting and a built-in timer; both  can help  your unit use less energy. Some units will be able to be controlled  through Alexa, Google or something similar.
• 更大并不总是更好. Purchasing a unit that is too large is less efficient because of increased on/off cycling. 使用下面的图表来确定您需要的尺寸. 适用于房间空调机组, 尺寸的测量单位是英国热单位(BTU)。, 冷却能力的指示.

针对以下情况进行调整:

• 如果房间的阴影很大，将容量减少10%.
• 如果房间阳光充足，将容量增加10%.
• If more than two people regularly occupy the room, add 600 BTUs per person.
• 如用于厨房，可增加4000 btu容量.

窗房空调维修

• 使用时每月清洗过滤器. 用肥皂和水清洗泡沫过滤器，然后风干.
• 抽真空盘管翅片.

每日靠窗房间空调提示

• Install a timer on the unit if you want the room cool when you get home. Check to see the timer is rated for the amperage and voltage of your unit.

选择和安装吊扇

• ENERGY STAR certified ceiling fan/light combination units are 60% more efficient than conventional fan/light units. 节余主要来自于风扇上的照明, 所以如果你的风扇没有照明, 一定要购买能源之星认证的照明套件.
• 夏季和冬季的储蓄, buy a reversible fan that will create a down-draft in summer and reverse to circulate warmer air near the ceiling in winter.
• Install the fan with the blades at least seven feet above the floor, 离天花板一英尺，离最近的墙两英尺.
• Consider the size of the room and the size of the blades when selecting a ceiling fan. 超过18英尺的房间可能需要多个风扇.

吊扇的日常小贴士

• 离开房间时把电扇和灯关掉. 风扇不是让房间凉快，而是让人凉快. 当循环空气通过你的皮肤时, 它吸收蒸发的水分, 让你感觉体温下降了4度.
• 如果你的吊扇有可逆电机, reverse the fan during the winter months to produce a gentle updraft, 是什么迫使天花板附近的热空气向下进入房间.

选择和安装蒸发冷却器

• Select a unit that has two or three blower speeds and a thermostat that automatically turns the cooler on and off.
• Sizing an evaporative cooler is less critical than sizing an air conditioner. The suggested guideline is about 3 cubic feet per minute (CFM) of airflow per square foot of area to be cooled.
• Place your evaporative cooler in a place free of outdoor obstructions, 通风口或燃烧装置. 确保你能给它安装一根供水管道.

蒸发冷却器维护

• Have your cooler serviced twice a year — once before the cooling season and once during the summer.
• 在冬季来临之前，这个单位有专业的防寒措施吗.

蒸发冷却器的日常小贴士

• 蒸发冷却器可以将室外空气冷却15到20度. 湿度越低，冷却效果越好. Cooled air from an evaporative cooler will add humidity to your home.
• Leave at least one window open while operating an evaporative cooler. The cooler air will go to the rooms with airflow and push the existing air to the outside.
• 在中等温度下(85度或更低), use just the evaporative cooler fan to draw cooler outdoor air into the home without using the cooling media to cool the air.
• Expect to use about one-third of the electricity needed to operate an air conditioner of similar capacity. However, your cooler will use anywhere from 3 to 15 gallons of water per day.
