Oil furnace died and needs replaced

*****update! I have managed to secure some Funds outside of GoFundMe. So I have changed the goal. We are so close our puppies are so excited! And we are truly thankful for all the help!*****

We are needing to replace our furnace.  Our
current one wouldn’t start at the beginning of cool weather. Tech came out and said it had a nice 60 year life but now it’s dead. Replacement and installation will be $7200 . They will at least put the diagnostic fee of $120 towards the purchase.  We have been using  space  heaters for 2 months. Fine for us people but our puppies get cold.
