空调维修检查表
1. 空调开不了
There can be several causes why your air conditioning won’t start: a tripped circuit breaker, 错误的恒温器设置, 关闭的开关或溢出的冷凝水排水盘.
触发断路器
Your system won’t turn on when you have an overloaded breaker.
To check if one has tripped, locate your house’s main electrical panel. You can spot this gray box on the wall in the basement, garage or closet.
- Make sure your hands and feet are dry before you work on the panel or breakers.
- Look for the breaker marked “AC” and ensure it’s in the “on” location. 如果过载，开关将处于“关”的位置.
- 稳定地转移开关回到“开”的位置. If it instantaneously flips again, leave it alone and get in touch with us at . A breaker that keeps flipping could signal your home has electrical trouble.
不准确的恒温器设置
If your thermostat isn’t signaling your system to start, it won’t turn on.
第一步是确保它被设置为“冷却”而不是“加热”.否则你的空调可能开不了. You may also get warm air moving from vents since the heater is running instead.
如果你使用传统的恒温器:
- 如果显示器是透明的，请更换电池. If the monitor is displaying garbled letters, get a new thermostat.
- 检查是否显示正确的设置. If you can’t change it, cancel it by dropping the temperature and hitting the “hold” button. 这将迫使你的AC工作，如果调度错误.
- Attempt to set the thermostat 5 degrees cooler than the house’s temperature. Your AC won’t cool if the thermostat is set the same as the house’s temperature.
Once your thermostat is adjusted properly, you should start getting cold air quickly.
如果你依赖智能恒温器, 包括Nest制造的手机, Ecobee, 勒克斯, 霍尼韦尔、博世, 查看制造商的网站寻求帮助. 如果你还是不能让它工作，打电话给我们寻求帮助.
断开开关
你的系统通常在冷凝器旁有一个关闭手柄. 这种开关通常安装在你家里的一个金属盒子里. If your equipment has recently been worked on, the switch may have accidentally been turned off.
溢流冷凝水排水盘 
Condensate drain pans keep the additional water your air conditioner pulls from the air. This pan is located either below or inside your furnace or air handler.
当下水道堵塞或堵塞时, water can accumulate and initiate a safety setting to switch off your unit.
如果你的平底锅有PVC管或排水管, you can clear the surplus condensation with a custom pan-cleaning tablet. You can purchase these tabs at a home improvement or hardware shop.
如果你的锅有一个泵，寻找浮子开关. If the lever is “up” and there’s moisture in the pan, you could need to replace the pump. 向我们求助.
2. 空调吹出温暖的空气
If your air conditioner is going but not providing cold air, its airflow may be obstructed. 或者可能没有足够的制冷剂.
阻塞气流
Your system’s airflow can be limited by a plugged air filter or dirty condenser.
如何更换空气滤清器
一个肮脏的过滤器会导致无数的问题，比如:
- 较低的气流
- 冷冻管路或蒸发器盘管
- 不一致的冷却
- 更大的冷却账单
- 让你的身体机能衰竭得更快
We propose installing new flat filters once a month, and pleated filters every three months.
如果你不记得上次更换过滤器是什么时候, 完全关闭你的系统，并拉出过滤器. You can spot the filter in your furnace or air pump’s blower compartment. It might also be located in a connected filter holder or wall-mounted return air grille.
把滤镜对准光线. If you see a lot of dust, you certainly should buy a new filter.
4步骤清洁制冷系统
杂草、植物和树枝会堵塞冷凝系统. This can limit its airflow, lower its energy efficiency and affect your comfort. 这里有一个方法，你可以让你的单位工作得很好.
- Switch off the electrical current totally at the breaker or external switch.
- 清除空调周围的绿色废物. 一旦你清除了两英尺半径内的所有杂物, you can use a soft brush or vacuum to slowly remove dirt from the condenser fins. 弯曲的鳍也可以冲击能力.
- Use a hose nozzle to carefully remove gunk off the fins from inside the equipment. 不要把水弄到风扇马达上.
- 重新打开电源.
制冷剂水平低
空调机组制冷剂不足时, they’ll have to work much harder to remove heat and humidity from your home.
Here are a few indications that your unit is seeping refrigerant:
- It takes an extended amount of time to cool your residence and you’re regularly lowering the thermostat.
- Air conditioning blowing through the registers isn’t as chilled as it should be.
- You’re hearing hissing or burbling sounds when the air conditioning works.
- Your evaporator coil is icy on account of having an issue absorbing warmth.
担心你的设备制冷剂泄漏? You need a licensed heating and cooling service expert to take care of the leak and replenish the correct measurement of refrigerant in your unit. 请联络我们以寻求帮助.
3. 空调没有吹足够的空气
当你似乎没有足够的冷空气, there’s likely a blockage or separation within your air conditioning unit.
- 首先要检查你的空气过滤器. 如果它脏了，就换掉.
- 确保所有房间的管道系统都是打开的.
- 如果你仍然没有接收到足够的冷空气, you should have your ductwork checked by a expert like 网赌博彩十大信誉平台. Your ductwork could need to be serviced or hooked up again in difficult areas like your attic, 地下室或爬行空间.
