Your furnace has served you well for however long you have had it. 确定, 你可能经历了一些起起落落, and there might have been times when the furnace needed repair or some attention. 不过，在很大程度上，多年来，它已经能够让你的家保持舒适.
然而，总有一天，即使是最可靠的炉子也需要更换. Often, a furnace will provide some hints and signs that it is due for replacement. 以下是在决定你的最佳选择是修复还是 代替你的炉.
1. 你在处理频繁的熔炉维修
It is a chilly day, so you turn the thermostat up a few degrees. Your furnace starts to cycle on, then nothing happens. Or, maybe you have noticed that your gas furnace is not working at all.
如果一个赛季或几年只发生一次，这似乎不是什么大问题. 但是，当你的炉子开始频繁故障，或者当你每年都请维修技术员来做的不仅仅是简单的检查和调整, it might make more sense economically to replace the furnace.
乍一看，修理一个炉子的成本比投资一个全新的炉子要低. Repair bills can usually be in the few hundred dollar range, while replacement bills can be in the several thousand dollar range. 一旦你有两个或更多的维修账单, 虽然, or if you are paying to fix up the furnace every single year, 你可能会发现你在旧炉子上的花费比你在新炉子上的花费要多.
To determine whether a replacement furnace is worth it financially, 看看你的修理费用. 如果你有一个新的炉子，你的账单是买一个新炉子或更多的费用的一半, 换掉它是有意义的. 更换旧炉的经济意义甚至更低. 如果你的炉子超过10或15年, 如果修理费用是价格的10%或20%，你就会考虑更换它.
更换炉 that constantly needs repairs will do more than help you save money. 它还节省了你的时间. Rather than having to call in a technician multiple times a year, you can have the replacement installation performed once, leaving you free to live your life and take care of your family and household.
2. 你的取暖费一直在大幅上涨
炉 work by burning fuel, such as heating oil or propane gas, to produce heat. 在一个完美的世界里，熔炉所使用的100%的能量应该用于产生热量. 在现实中, 小于100%, even among the most energy-efficient oil or gas furnaces.
一般来说，你的炉子越老，它的能源效率可能越低. 的 reduced energy efficiency is due to two factors. 其一，旧炉的设计通常不如新炉的设计高效. 两个, 随着炉子的老化，它们的能源效率越来越低, 由于零件和系统的磨损.
年度燃料利用效率，或AFUE，衡量一个炉子的能源效率. AFUE将炉子产生的总热量与它所消耗的燃料能量进行比较. 的 higher the AFUE rating, the more efficient a furnace will be. 的 minimum AFUE rating of a residential furnace is 78. 炉 that earn the Energy Star label need an AFUE rating of at least 油动力系统85 而在美国，燃气动力系统则为90英镑.S. 南.
你的炉子正在失去能源效率的一个迹象是家庭能源账单的增加. 如果你家的温度和往年一样，而且天气也没有异常寒冷, but you need to refill your oil or propane tank more frequently, 检查一下你的炉子是个好主意. 的 problem could be a small and easily fixable one, such as replacing the filters to help the furnace run more smoothly. 然而, 也有可能是炉子需要更复杂的修复才能恢复到以前的效率.
如果炉子是旧的, you are likely better off replacing it with a newer, 更节能的模型. You will save money in the long run on repair bills and energy bills.
3. 你的炉子旧了
旧炉子比新炉子消耗更多的能源. 的y are also more prone to breakdowns and more likely to need costly repairs.
How can you tell if your furnace is 太 old and should be replaced? 的 advertised gas or oil furnace life expectancy is often 20 to 30 years. 通常, 虽然, 一旦炉龄达到10年或15年, 是时候开始考虑更换了. Your furnace might reach its 20th or even 30th birthday, 但这也可能会让你在维修费用或更高的能源消耗方面花费很多.
如果你发现自己经常给技术人员打电话，或者你的能源账单比以前高了, 你的旧炉子可能该换了. 如果你不确定你的旧炉子是否应该更换，明升亚洲手机版能源公司可以提供帮助. 在一个家庭 能源咨询, 我们将查看您当前的系统, 测量你的家，与你讨论你的能源需求，以确定一个新的炉子是正确的选择.
4. 你的炉子发出噪音了
每个炉子在运转时都有一些噪音. It is likely to hum as the burner turns on and ignites the fuel. 你可能会听到一种嗖嗖的声音，因为空气通过你家的管道. 一旦一个周期结束，你可能会听到砰砰声或砰砰声，因为管道冷却.
一些炉子的噪音可能是一个值得关注的原因. 例如, 从炉子发出的一声巨响可能表明燃料已经在系统中积聚，当炉子打开时，燃料已经全部点燃. 如果燃烧器脏了或者阀门有问题，就会发生燃料积聚. 在某些情况下, the buildup can cause the heat exchanger to crack, which might require an expensive repair or total replacement of the system.
其他能发出信号的炉声是时候更换了，包括:
- 尖叫: 一声尖锐的尖叫或金属摩擦金属的声音可能意味着什么东西落错了地方, 折断的或松动的. Depending on the extent of the damage, a new furnace might be your best option.
- 抱怨: A high-pitched whine can point to a problem throughout the furnace. 一名训练有素的技术人员将能够检查你的炉子，并检测出发出呜呜声的来源, 以及建议下一步做什么.
- 隆隆: 当空气通过管道或燃料点燃时，炉子可能发出隆隆声. 但如果这种隆隆声持续且响亮, it could be a sign that there is an issue with the burner or ignition system.
5. 你的炉子开始看起来不一样了
When it was first installed, your home’s furnace most likely looked shiny and new. As the years have gone by, it has likely lost that shiny newness. While it is common for appliances to start to show signs of wear and tear, 在某种程度上, those signs can signal that is it time to replace your equipment. Some appearance changes to keep an eye out for include:
- 锈: A furnace can rust in areas where metal is exposed to combustion gases. Over time, rust can be an issue as it weakens the structure of the furnace. Cracks can develop in rusted areas, increasing the chance of leaks and other issues. 如果你的炉子随着时间的推移锈迹斑斑, the best thing to do might be to have a new one installed.
- 条纹的烟灰: 煤烟的形成是不完全燃烧的结果，不完全燃烧可能意味着炉子正在产生大量的一氧化碳. Cleaning the furnace and having it inspected can help. 您的技术人员可能会根据系统的年龄和整体状况建议更换.
- 裂缝: 裂纹的形成可能是由于广泛的生锈或由于热交换器的问题. Any type or size of crack should be a cause for concern, 如果你看到一个, call a technician to have them assess the situation and let you know what to do next.
6. 你正在经历湿度问题
It is not just temperature that affects your home’s comfort level. It is also the amount of moisture, or humidity, in the air. 当家里的空气非常潮湿时, 模具可以茁壮成长, which can contribute to breathing problems and respiratory illnesses. 高湿度还会导致墙壁和房屋结构腐烂，并导致墙壁和天花板上形成污渍. Some pests love moisture and are more likely to infest humid homes.
Humidity levels that are 太 low can also be a cause for concern. Dry air can dry out the skin, making it flaky and itchy. 干燥的空气也会使鼻腔干燥, potentially causing respiratory issues or trouble breathing. 当家中湿度过低时, you are more likely to get shocks from static electricity, 太.
与旧的炉子相比，新的炉子通常能更好地处理湿度问题. If your home is very dry in the colder months of the year, your furnace might be playing a significant role in the overall air quality. 升级到一种新型号, 也许是一个内置加湿器的新型号, 可能有助于解决你的问题.
7. 你的房子感觉加热不均匀
Ideally, your furnace should heat all areas of your home evenly. 随着年龄的增长, 虽然, 它可能很难将等量的暖空气推向房子的各个部分. 如果你的房子是多层的，或者有些房间比其他房间离火炉更远，这一点尤其正确.
Age is not the only reason why a furnace might struggle to heat your home evenly. If the system is 太 large or 太 small for the size of your home, 它可能无法提供均匀的热量. 一个超大的炉子可能会频繁地开关，可能永远没有机会将热量传递到遥远的房间. 一个尺寸过小的炉子可能工作太辛苦，导致一些区域过热，而另一些区域保持低温.
Uneven heat in the home is not always caused by the condition or size of the furnace, 这就是为什么让明升亚洲手机版能源的认证和训练有素的技术人员评估你的情况是一个好主意. 可能是你的炉子仅仅需要新的空气过滤器，或者某个房间的一个通风口被关闭或被堵住了. 在评估情况后, our technicians can help decide if repair or replacement is the way to go.
