Question 20 year old furnace, is too old ?

How do I know when it's time to have my 20-year old furnace replaced with new one ? It work OK.

We are selling house in a year, so I'd prefer to avoid buying new one, unless absolutely neccesary.

Thanks,
Alex

FURNACE WHEN IT DONT WORK

Hey if your going to sell in a year and it works fine let it alone. Oil the blower motor and but a new air filter in. You dont say gas or oil. You could just have a tech service it and stop at that for now ED

Thumbs up 20 year old furnace - clarification

Thanks for your comments, folks.

It's a gas forced air type furnace, made by Borg Warner, model P9UGD07N05001A.

Rated output 11.7(40) kW(Btux).
Normal Input 14.7(50) kW(Btux).

Thanks again,
Alex

I'd say leave it alone. Just because it's old doesn't mean anything, if it has been well maintained. Of course, it's not as efficient as some of the newer ones.

No, both are there.
11.7 kW, 40 kBTU (probably output)
14.7 kW, 50 kBTU (probably input)

It's a gas furnace, but Input/Oputput charactaristics are as I indicated previously, i.e.

Rated output 11.7 kW (40 Btux).
Normal Input 14.7 kW (50 Btux).

Not sure how do they measure gas furnace input/output in kWs,

Alex

kW are a unit of power, BTU are energy. If you assume the BTU is per hour, you have a unit of power. The conversion is actually easy. 1 kW is 3412 BTU/hour.
