【求助】有关furnace的问题

想问一下，furnace已用17年了，启动时噪音很大，是不是该换了？ 担心那天真坏了，再换就晚了。

该换了。

Buying a furnace is more complex than buying the grocery. My suggestion would be to look into buying / installing the furnace right now, get all the information / model / pricing / company / appointment delay /etc, all the details ready.

Once your furnace goes wrong, or there's a big sale/discount/promotion, you can pull the trigger right away.

要看热效率指标：高的（90+%）能用则用，低的（75-%，你的可能是这一档的）就基本该换了。

十七年，多半是中效炉，换掉吧，联邦大概还能补贴几百刀。可惜安省的已经没有了。高效炉可以省很多，至少30%吧。
