你开始听到奇怪的声音了吗, 如呼呼, 碰撞或发出叮当声的, 来自你们的暖通空调系统? 或者，你是否注意到你家里的温度不再像以前那样舒适? 在寒冷的月份里，你可能会一直发抖, even though the thermostat says the temperature is 70 degrees. In the warmer months, it might seem like some rooms never seem to get cool enough.
Your HVAC system is designed to have a relatively long life, but there might be times when your system has issues and needs some attention. 知道要注意什么将帮助您确定您的暖通空调是否需要维修或是否需要更换它.
为什么暖通空调系统维护很重要
When is the last time you gave your HVAC system much thought? 许多房主在家里的供暖和制冷系统出了问题之前都不会去想太多, 如听到设备发出的奇怪声音，或注意到内部温度过高或过低.
留出一些时间来检修你的暖通空调系统，每年对它稍加关注，可以帮助它尽可能长时间地保持良好的工作状态, minimizing the need for extensive repairs or even replacement.
常规的 空调维修 includes an annual tune-up and inspection of your system. 在发动机的调整, 执行该工作的nate认证技术人员将通知您，如果他们注意到设备当前的任何问题或可能在以后发展的潜在问题. 他们还会让你知道建议的行动过程是什么，以及一个特定的修理可能需要多少钱.
当潜在的问题和担忧还很小的时候就发现它们，可以让你迅速采取行动. 在问题发展成主要问题之前解决它意味着你可以省钱. It also reduces the risk of the system breaking down, leaving you without heat or air conditioning for any length of time.
定期的暖通空调维护也有助于您的系统更好地运行，并提高您的家庭的安全性. 现代暖通空调系统有空气过滤器，防止灰尘和碎片通过管道系统进入你的家. 的 filters can become full and clogged after months of use, 这意味着它们不再能够正确地过滤空气中的灰尘和其他颗粒. Clogged air filters can also make your system work harder, 增加了它的磨损量. 常规的 维护 involves replacing the air filters to improve the 空气质量 in your home and to ease the amount of strain on your HVAC system.
Maintaining your HVAC system can also help you save money on energy bills. 一个系统在巨大的压力下或脏将需要更努力工作，以保持你的家舒适. 你的空调和火炉工作得越辛苦，它们需要使用的燃料和能源就越多. This can also lead to higher electricity and fuel costs, too.
6个迹象表明你的暖通空调系统需要维修
即使每年进行调整和维护, there is still a chance your HVAC system will need repair at some point in its life. 暖通空调故障排除包括了解需要寻找的迹象，以及如果系统开始显示其中任何一个迹象，应如何做. 的se are some of the signs that your heating and cooling equipment needs to be repaired.
1. 低效的水平
炉 and air conditioners are rated based on their overall energy efficiency. 的 年燃料利用效率 (AFUE) rating measures the efficiency of a furnace or boiler that uses oil or gas as fuel. 空调的能源效率是用季节能源效率比(SEER)来衡量的. 一个烧油的炉子 AFUE评分高于85 is considered to be energy-efficient, while a central air conditioner with a SEER评分超过12 是节能的.
Over time, the efficiency of heating and cooling equipment can drop. 例如, 过滤网堵塞或充满, it can reduce the efficiency of your air conditioner. Cleaning or replacing the filter can make your air conditioner 高达15%的效率.
You can often tell if the efficiency of your system has been affected, as it will usually need to work harder or run more often. 如果您的系统似乎启动更频繁或运行时间更长，当它打开时, 明升亚洲手机版能源公司的专业技术人员可以出来检查您的系统，并告诉您可能需要哪些维修.
2. 不均匀的温度
Do you notice that some areas of your home are hotter or colder than others? If so, your HVAC system might be contributing to the problem. When heating and cooling equipment is in need of upkeep or repair, 它常常不能使家里的温度均匀地升高或降低. 如果你觉得系统不能完全分配热或冷空气到你的家里, it might be due to a weak motor or fan that needs adjustment and cleaning.
3. 过多的灰尘
如果你的家里有过量的灰尘，或者空气中的灰尘加重了你自己或家人的过敏, your HVAC system might be at fault — at least in part. 系统中的空气过滤器可能已满，这意味着它无法过滤污染物. 如果是这样的话，更换过滤器可以帮助你和你的家人呼吸更顺畅.
在某些情况下, too much dust in the home is a result of ducts that are not well sealed. 灰尘和碎片可以通过管道连接的小开口或通过管道本身的孔或裂缝进入管道.
4. 湿度控制问题
除了温度，湿度也会影响你在家的舒适度. 当你家里的空气太干燥时，你可能会注意到你的皮肤也很干燥. A low humidity level can also dry out your nasal passages, making you more susceptible to discomfort as well as catching a cold or another illness.
家中湿度过大也是个问题. 当空气中有大量的湿气时, 模具可以茁壮成长, triggering allergic reactions and asthma in sensitive individuals. 高湿度也会导致腐烂，影响你家的结构和稳定性. When it is too humid indoors, it can feel warmer as well. Your thermostat might claim that it is a comfortable 70 or 72 degrees, but the high humidity can make it feel like it is 78 or 80 degrees.
A few signs will let you know if the humidity in your home is too high or too low. If you notice condensation forming on the windows inside your home, 这通常是湿度过高的迹象. 如果你穿过一个房间, 碰到门把手就会被电击, 这通常是湿度过低的迹象.
如果您的暖通空调系统的大小适合您的家庭, it should be able to help control the humidity levels, 确保你的房子既不太干燥也不太潮湿. 如果系统的大小不适合你的房子, 然而, it might struggle to keep humidity within an acceptable range. 暖通空调系统的磨损也会影响其控制室内湿度水平的能力. If you notice that your home is too dry in the winter or too humid in the summer, 安排一个约会 to have a technician take a look and diagnose the issue.
5. 噪音
During the course of normal operation, your HVAC system is going to make some noise. 你可能会听到一个温和的吹声，因为空气通过管道和寄存器或一个柔和的嗡嗡声，作为燃烧器踢上. 而有些噪音是常见和正常的, others are a sign that something is up and that your system most likely needs attention. 听起来很有趣 包括砰砰声、撞击声和口哨声. 如果你的系统开始发出刺耳的声音, 这通常也是一个信号，你应该打电话给技术人员，让他们检查你的设备.
6. 高企的能源账单
能源账单上的变化可能表明你的供暖和制冷系统可能需要维修了. 如果你像往常一样使用加热器或空调，而没有显著增加或减少恒温器, 你的能量消耗应该相对稳定. 然而, 如果你的暖气或空调需要更努力工作，以保持你的家在理想的温度, 这样做可能会消耗更多的能量. You might notice that you need to refill your heating oil or propane tank more often, 增加你的自付成本. 在空调的情况下，你可能会看到你的电费跳.
If you are paying more than you think you should be for heating and cooling, 让技术员检查你的系统. If the heating and cooling system is not in need of repair, 也许是时候换一个新的了, more energy-efficient model to help you get your energy costs under control.
When to Replace Your Air Conditioner or 加热 System
Although repairing your HVAC system when it is having problems, 比如制造噪音, not heating and cooling effectively or not turning on, can be the most appropriate option in certain cases, there might also come a time when replacing your system is the best call. Some signs that your air conditioner and heating system needs to be replaced include:
- 维修费用正在增加: 在某些情况下, the cost of the repair might be nearly the same as the cost of investing in a new system. 也可能是您的系统条件要求它经常进行维修. 从长远来看, 安装一个新的系统比继续修理旧的系统更划算.
- 这个系统很旧: 您的暖通空调系统的使用年限也会影响是更换还是维修更好. 当你的 设备已经用了10到15年了在美国，换掉它通常是有经济意义的. 不过你得先为新系统付费, 随着时间的推移，你可能会省下一笔钱，因为新的空调和火炉比旧的型号要节能得多.
- 你的能源账单非常高: 虽然有很多因素会影响你花多少钱来加热或冷却你的家, one factor that is within your control is the condition of your HVAC system. 如果你的系统没有达到应有的效率, you are most likely paying more for fuel or electricity than you would like to be. 用高效的模型代替低效的加热和冷却设备可以帮助你降低每月的能源成本.
