AI Overview
A standard gas furnace typically lasts between 15 and 20 years, though they can operate for over 25 years with excellent, consistent maintenance. It is generally recommended to start planning for a replacement once your furnace hits the 15-year mark to avoid emergency repairs during winter.
Key Considerations for Replacement
A standard gas furnace typically lasts between 15 and 20 years, though they can operate for over 25 years with excellent, consistent maintenance. It is generally recommended to start planning for a replacement once your furnace hits the 15-year mark to avoid emergency repairs during winter.
Key Considerations for Replacement
- 15-Year Rule: Once a furnace reaches 15 years old, it is considered "middle-aged" to old. Efficiency starts to decline, and components like the heat exchanger become more likely to fail.
- The 50% Rule: If the cost of a repair is 50% or more of the cost of a new furnace, replacing the unit is often more cost-effective than repairing it.
- Frequent Repairs: If you are calling a technician more than once per season, it is a sign that the system is failing and should be replaced.
- Energy Bills: A sudden increase in energy bills, despite constant usage, indicates declining efficiency.
- Warning Signs: Watch for loud noises (banging, squealing), uneven heating (cold spots), or a yellow flame (indicates potential carbon monoxide issues).
- Maintenance: Annual professional tune-ups can extend the life of your furnace by 5–10 years.
- Filter Changes: Changing filters every 1–3 months prevents strain on the motor, extending its life.
- Climate: In colder regions, furnaces work harder, which can shorten their lifespan compared to warmer climates.
- Replacement: A standard, straightforward furnace replacement usually takes 4 to 10 hours (one day) to complete.
- Complex Installation: If ductwork modifications or new venting are required, it may take 1 to 2 days.
- Replace filters every 1–3 months.
- Schedule annual professional maintenance.
- Keep the area around the furnace clean.
- Ensure carbon monoxide detectors are installed near the furnace.
本来以为是个小问题，结果怎么都没查出问题。电机就是不转。房子已经20多年了。干脆彻底换了新的Furnace。还好从打电话到安装好6个多小时！谢谢村长，谢谢大家帮忙出主意。

非常正确的决定.超过20年的暖炉坏了,修了这个备件,很可能下个备件又坏了,人工修理成本较高.
搜索"暖炉年龄"部分结果如下
冷暖知识普及系列13: 暖炉多久要更换？
一般来说，暖炉保养得当可以使用20-30年。
即使暖炉达到20或30年，如果暖炉很少出问题，不建议更换。渥太华达能冷暖(CanFix Heating and Cooling)冷暖知识普及系列13: 暖炉多久要更换？看完这个帖子就知道了，再也不会被别人忽悠了。
暖炉年龄
大多数暖炉的使用寿命为15到20年。如果您的暖炉接近或已经超过这个使用年限，即使目前仍在运行，也应考虑更换。一台老化的暖炉更容易在关键时刻发生故障，导致供暖中断。无论是旧空调还是旧暖炉,都是在最高温的时间或最低温的的时间最容易出故障.这不是错觉,而是事实.因为温度越高,空调启动越频繁,温度越低,暖炉启动越频繁.已接近年限的暖炉或空调经不起频繁工作的压力而熄火.
