What English do you need for daily life abroad?

Sure, I can come this afternoon. Before I head over, can you check a couple things? First, is the thermostat set to 'cool'? And second, is the outdoor unit running?

可以，我今天下午来。来之前你能检查几样东西吗？首先，温控器设在'制冷'模式吗？其次，室外机在运转吗？

That could be a refrigerant issue or a failing compressor. I'll bring my gauges and check the pressure. The service call is $85, which covers the first hour of labor.

可能是制冷剂问题或压缩机故障。我带压力表来检查。上门费85美元，包含第一个小时的人工。

I can be there by 2 PM. In the meantime, keep the windows closed and try not to run the system — running it with low refrigerant can damage the compressor further.

2点之前到。这段时间窗户关好，尽量别开系统——制冷剂不足时运行会进一步损坏压缩机。

Sounds good. If you have pets, please make sure they're secured — I'll need access to the air handler, which is usually in a closet or utility room.

好的。如果有宠物请看好——我需要检查空气处理机，通常在壁橱或设备间里。

Absolutely. I recommend a tune-up twice a year — once in spring before cooling season and once in fall before heating season. It catches problems early and extends the life of your system.

当然建议。我推荐每年两次保养——春天制冷季前一次，秋天供暖季前一次。能早发现问题，延长系统寿命。

We check refrigerant levels, clean the coils, replace the air filter, test the thermostat calibration, inspect electrical connections, and lubricate moving parts.

检查制冷剂水平、清洗盘管、更换空气滤网、测试温控器校准、检查电气连接、润滑活动部件。

Our annual plan is $180 for two visits. It includes priority scheduling, 15% off parts, and no service call fee if something breaks between visits.

年度计划180美元包含两次上门。包括优先排期、零件85折、两次保养之间出问题免上门费。

Every one to three months, depending on whether you have pets or allergies. A dirty filter makes the system work harder and drives up your energy bill. It's a $5 filter that can save you hundreds.

一到三个月，取决于你是否养宠物或有过敏。脏滤网会让系统更费力，增加电费。5美元的滤网能省几百。
