How long do wall furnaces last

4 Replies

I'm in Michigan so this is in regards to the northern country. Do wall furnaces last 20 years? Do they break down a lot and need to be serviced every few years or more? What is the general opinion of them?

Are you referring to electric wall heaters? I have some in my rentals that are 40 years old and still work. 

We have a duplex that has gas fired wall units in them. Originals were installed when the place was built in the 50's. We purchased 16 years ago and replaced each one within the first few years. No issues since then.

We have them checked every every year before heating season for safety.

Cheers!
